GMO 季度信函 2012 年 7 月 欢迎来到反乌托邦!

GMO Quarterly Letter July 2012 Welcome to Dystopia!

进入一场长期且具有政治危险的粮食危机 杰里米·格兰瑟姆(第 2–18 页) 当糟糕的事情发生在廉价资产上 本·英克(第 19–22 页) GMO 季度信函 2012 年 7 月 欢迎来到反乌托邦! 1 进入一场长期且具有政治危险的粮食危机 2 杰里米·格兰瑟姆 “他们肚子饱了,我们却饿了……饥饿的人是个愤怒的人……饥饿的暴民是一群愤怒的暴民。”——鲍勃·马利,《他们肚子饱了》 “任何认为在一个有限的世界里指数级增长可以永远持续下去的人,要么是个疯子,要么是个经济学家。”——肯尼思·博尔丁,经济学家 摘要的摘要 我们正处于一场严重的全球粮食危机之中,这场危机已经持续了五年,而且极不可能消失。它将威胁贫困国家,导致营养不良和饥饿加剧,甚至社会崩溃。资源争夺和一波波由粮食引发的移民潮将威胁全球稳定和全球增长。几乎所有人以及所有机构——可能除了一些军事机构之外——都严重低估了这一威胁。

Entering a long-term and politically dangerous food crisis Jeremy Grantham (pages 2-18) When Bad Things Happen to Cheap Assets Ben Inker (pages 19-22) GMO Quarterly Letter July 2012 Welcome to Dystopia! 1 Entering a long-term and politically dangerous food crisis 2 Jeremy Grantham “Them belly full but we hungry ... … A hungry man is a angry man ... … A hungry mob is a angry mob.” —Bob Marley, “Them Belly Full” “Anyone who believes exponential growth can go on forever in a finite world is either a madman or an economist.” —Kenneth Boulding, Economist Summary of the Summary We are five years into a severe global food crisis that is very unlikely to go away. It will threaten poor countries with increased malnutrition and starvation and even collapse. Resource squabbles and waves of food-induced migration will threaten global stability and global growth. This threat is badly underestimated by almost everybody and all institutions with the possible exception of some military establishments.

第一项总结。去年我们公布的数据显示,人类已进入一场范式转变或阶段变化达 10 年之久——资源价格从持续下跌转向相当迅速的实际上涨。

Summary 1. Last year we reported the data that showed that we are 10 years into a paradigm shift or phase change from falling resource prices into quite rapidly rising real prices.

2. 现在看来,我们大约也已陷入一场全球性粮食危机达五年之久,这场危机不太可能在几十年内消退,至少要到全球人口从 2050 年可能超过 90 亿的峰值大幅下降之后,才有可能缓解。

2. It now appears that we are also about five years into a chronic global food crisis that is unlikely to fade for many decades, at least until the global population has considerably declined from its likely peak of over nine billion in 2050.

3. 普遍的假设是,到 2050 年,我们需要将粮食产量提高 60% 到 100%,才能为超过 90 亿人提供至少基本足量的热量,同时为发展中国家迅速壮大的中产阶级供应更多肉类。

3. The general assumption is that we need to increase food production by 60% to 100% by 2050 to feed at least a modest sufficiency of calories to all 9 billion+ people plus to deliver much more meat to the rapidly increasing middle classes of the developing world.

GMO 2 季度信函——欢迎来到反乌托邦!——2012 年 7 月 4\. 人们普遍认为,至少这一目标的下限将得以实现。我认为这个看法相当乐观。即便我们真的达到了那个水平,也根本无法维持住。更可能出现的情况是,我们根本接近不了那个目标,因为太多因素会让原本容易实现的粮食产出增长变得越来越困难:• 自 1970 年以来,粮食生产率每十年都在下降,从 3.5% 降到 1.5%。很可能,最高效的粮食生产者正接近“玻璃天花板”,此时每英亩生产率的进一步提升在大麦物种的极限处趋近于零(正如赛马现在跑得并不比 1920 年代快多少一样)。值得注意的是,全球农业研究投资占 GDP 的比重一直在稳步下降。• 水资源问题将加剧到一定程度,以至于灌溉增产带来的收益将被地下水枯竭和土壤盐碱化所抵消。

GMO 2 Quarterly Letter – Welcome to Dystopia! – July 2012 4. It is also widely assumed that at least the lower end of this target will be achieved. I believe that this is substantially optimistic. At very best, if we reach that level we will not be able to hold it. Much more likely, we will not come close because there are too many factors that will make growth in food output increasingly difficult where it used to be easy: • Grain productivity has fallen decade by decade since 1970 from 3.5% to 1.5%. Quite probably, the most efficient grain producers are approaching a “glass ceiling” where further increases in productivity per acre approach zero at the grain species’ limit (just as race horses do not run materially faster now than in the 1920s). Remarkably, investment in agricultural research has steadily fallen globally, as a percent of GDP. • Water problems will increase to a point where gains from increased irrigation will be offset by the loss of underground water and the salination of the soil.

• 持续的不良农耕实践不断加剧土地退化,这将继续削弱我们长期可持续的生产能力。• 过去 50 年间化肥使用量增长了 5 倍,边际上增加化肥用量所带来的增量回报将稳步下降,唾手可得的收益早已成为过去。

• Persistent bad farming practices perpetuate land degradation, which will continue to undermine our long-term sustainable productive capacity. • Incremental returns from increasing fertilizer use will steadily decline on the margin for fertilizer use has increased five-fold in the last 50 years and the easy pickings are behind us.

• 天气将变得更加不稳定,特别是洪水和干旱,同时气温也会持续上升。过去三年的全球天气糟糕到了这样的程度——要随机抽出连续三个这样的年份,可能性微乎其微。气候正在发生变化。

• There will be increased weather instability, notably floods and droughts, but also steadily increasing heat. The last three years of global weather were so bad that to draw three such years randomly would have been a remote possibility. The climate is changing.

• 肥料和燃料的成本将迅速上升。

• The costs of fertilizer and fuel will rise rapidly.

5. 即便我们能在全球范围内生产出足够的粮食来让所有人吃饱,投入成本的持续稳步上涨也意味着越来越多的人将买不起我们生产的粮食。这是一个常被忽略的关键点。

5. Even if we could produce enough food globally to feed everyone satisfactorily, the continued steady rise in the cost of inputs will mean increasing numbers will not be able to afford the food we produce. This is a key point that is often missed.

6. 从积极方面看,科学家们现在相当乐观地认为,他们能在大约 20 到 30 年内,把更高效的光合作用“C4”基因(玉米就属于这一类)改造到效率较低但至关重要的“C3”植物(比如水稻和小麦)中去。如果成功,这将使产量提升多达 50%,并为向可持续人口水平过渡争取更多时间,减少痛苦。

6. On the positive side, scientists are now very optimistic that they will be able to engineer more efficient photosynthesizing “C4” genes (corn belongs to that family) into relatively inefficient but vital “C3” plants such as rice and wheat, in 20 to 30 years. If successful this would increase output up to 50% and would buy time for a less painful transition to a sustainable population.

7. 许多日益加剧的困难体现在最初的 2008 年粮食危机和 2011 年的价格反弹上。过去六周的涨价更具威胁性,因为这次涨价发生在播种面积远超 2008 年的情况下。全球需求如今如此之高,增长如此之快,而储备又如此之低,以至于价格对天气不利因素的敏感度已变得极为极端。

7. Many of these increasing difficulties were reflected in the original 2008 food crisis and the 2011 rebound. The last six weeks’ price rise is more threatening because it occurred despite very much larger plantings than were available in 2008. Global demand is now so high and rising so fast and reserves are so low that price sensitivity to weather setbacks has become extreme.

8. 有几个依赖进口粮食的国家似乎至今仍未从 2008 年的冲击中恢复过来。比如埃及,其消费者预算中用于食品的比例已经上升到 40%。在这一水平上,社会压力可能已处于极端状态,或许已经为“阿拉伯之春”运动推波助澜。今后的任何涨价都可能导致社会崩溃,并引发一场和平时期前所未有的移民浪潮。若粮食价格再翻一番,后果将是灾难性的。

8. It seems likely that several countries dependent on foreign grain imports have in fact never recovered from the 2008 shock. Countries like Egypt saw the percent of their consumer budget for food rise to 40%. At this level, social pressures may be at an extreme and probably have already contributed to the Arab Spring. Any price increases from here may cause social collapse and a wave of immigration on a scale never before experienced in peacetime. Another doubling in grain prices would be catastrophic.

9. 旨在防止粮食危机的强力应对措施,本可以有效遏制当前危机,并阻止事态演变为更严重的危机,但这些措施很可能不会被采取。原因在于,富裕国家感受到的价格信号太弱——它们负担得起更高的价格——而且整个系统各个环节都存在惯性。此外,遥远国家的营养不良问题,在富裕国家通常不被视为高度优先事项。

9. Strong countermeasures to prevent a food crisis would be effective in curtailing the current crisis and preventing the development of a much greater crisis, but these measures will likely not be taken. This is because the price signals for the rich countries are too weak – they can afford the higher price – and there is inertia in all parts of the system. Also, the problems of malnutrition in distant countries are not generally felt as high-order priorities in the richer countries.

10. 如果粮食压力再次出现,并且因燃料价格上涨而加剧,那么社会崩溃和全球不稳定的风险就会攀升到一定程度,很可能成为国际冲突的主要根源。中国对资源稀缺,尤其是粮食问题,特别担忧(甚至有些绝望)。

10. If food pressures recur and are reinforced by fuel price increases, the risks of social collapse and global instability increase to a point where they probably become the major source of international confrontations. China is particularly concerned (even slightly desperate) about resource scarcity, especially food.

GMO 3 季度信函——欢迎来到反乌托邦!——2012 年 7 月 11. 公众、媒体、金融市场以及各国政府都严重低估了这些风险。只有包括美国和英国在内的一些国家的军方,似乎才对此有恰当的认识。12. 天然气供应的增加为(主要是美国)争取了一些时间,但似乎更可能滋生自满情绪,并导致对碳氢化合物的持续依赖。全球范围内,能源问题在短期内的紧迫性不及粮食问题。能源供应充足,只会导致价格缓慢而不稳定地上涨。石油的主要问题在于,它通过推高农业生产成本,并普遍加剧贫困国家的成本压力,从而加剧了粮食问题。

GMO 3 Quarterly Letter – Welcome to Dystopia! – July 2012 11. The general public, the media, the financial markets, and governments badly underestimate these risks. Only the military of some countries, including the U.S. and the U.K., seem to appreciate them appropriately. 12. Natural gas supply increases buy some time, mainly for the U.S., but seem more likely to create complacency and continued dependence on hydrocarbons. The energy situation is less pressing globally in the short term than is the food problem. Supplies are sufficient to cause merely a slow and erratic price increase. The main problem with oil is in its contribution to the food problem through higher farming costs and generally increasing cost pressures on poorer countries.

13. 反观长期来看,能源成本以及石油的绝对短缺构成了仅次于粮食短缺的严重问题,并将导致价格高企,进而影响全球增长,甚至危及现代经济——这些经济本就相当脆弱——的存续能力。

13. In the longer term, in contrast, energy costs and absolute shortage in the case of oil form a serious problem second only to food shortages and will result in prices so high that they will impact global growth and even the viability of modern, rather fragile, economies.

14\. 不过,从纸面上看,能源问题可以通过对可再生能源和智能电网的巨额投资得到相对容易的解决。那些这样做的国家,几十年后最终将在更低的边际成本和能源安全方面占据巨大优势。包括美国在内的大多数国家,将无法凝聚起足够的政治意愿来克服惰性、一厢情愿的想法以及能源利益集团巨大的政治影响力,从而难以启动这些昂贵的计划。它们有在竞争力上被甩在后面的风险。

15\. 相比之下,在未来几十年里,金属的可得性只是一个小问题。价格会稳步上涨,但后果不那么严重。然而,长期来看,金属是最棘手的问题。它不像农业那样有脑力密集型解决方案(即有机农业),也不像能源那样有资本密集型或技术密集型解决方案。我们只会慢慢地耗尽它,而价格上涨。

16\. 这些问题的后果,在富裕国家主要体现为价格压力。获取充足资源的需求将挤压国家预算、利润率以及经济增长。但对于穷国而言,这简直就是生死攸关的问题。

14. On paper, though, the energy problem can be relatively easily addressed through very large investments in renewables and smart grids. Those countries that do this will, in several decades, eventually emerge with large advantages in lower marginal costs and in energy security. Most countries including the U.S. will not muster the political will to overcome inertia, wishful thinking, and the enormous political power of the energy interests to embark on these expensive programs. They risk being left behind in competiveness. 15. Availability of metals is, in contrast, a minor problem in the next few decades. The prices will steadily rise but the consequences will be less. In the long run though, metals are the most intractable problem. There is no brain-intensive solution as there is for agriculture (i.e., organic farming), nor is there any capital-intensive or technology-intensive solution as there is for energy. We will just slowly run out and prices will rise. 16. The results of these problems will be felt mainly as price pressure in rich countries. The need to obtain adequate resources will squeeze national budgets, profit margins, and economic growth. For poor countries, though, it is literally a matter of survival.

17. 我们天生就不擅长应对这个问题:遗憾的是,我们并非投资理论中描述的那种高效物种,而是信息闭塞、容易被操控、充满惰性且容易堕落的存在。只有在极其罕见的情况下——比如第二次世界大战——我们的表现才能勉强接近理论上的能力极限,而这一次的敌人形态模糊,攻击方式又极其缓慢。但全球面临的利害关系确实非常重大。我们必须更加努力。18. 以下关于此话题的评论仅代表我个人观点,反映的是我基金会的投资组合(而且完全没有职业风险!)。这些评论基于十年及以上的时间跨度。其投资组合的含义是:随着资源实际价格上升,投资者应该预期资源类股票——即那些在地下拥有资源的公司——在未来几十年中表现优于大盘。不过,农业和林业处于优先地位。严肃的长期投资者应该在资源类组合中持有非常显著的超配仓位。我建议长期投资者的资源类仓位至少达到 30%。资源压力下的另一个相对受益者是优质股票群体。优质股票在最终销售额中的资源占比低于平均水平,且利润率更高,使其更能抵御利润率压力。

17. We are badly designed to deal with this problem: regrettably we are not the efficient species of investment theory, but ill-informed, manipulated, full of inertia, and corruptible. Only once in a blue moon – like World War II – do we perform anywhere near our theoretical capabilities and this time the enemy is amorphous and delivers its attack very, very slowly. But the stakes globally are very high indeed. We must try harder. 18. The following comments on this topic are mine personally and reflect my Foundation’s portfolio (and a total lack of career risk!). These comments are based on a time horizon of 10 years and beyond. The portfolio investment implications are that investors should expect resource stocks – those with resources in the ground – to outperform over the next several decades as real prices of the resources rise. Farming and forestry, though, are at the top of the list. Serious long-term investors should have a very substantial overweighting in a resource package. I suggest for long-term investors a resource position of at least 30%. Another relative beneficiary of resource pressure is the quality group of equities. Resources are a smaller fraction of final sales than average and higher profit margins make them more resilient to margin pressures.

19. 或许更重要的是,资源紧张加上其他抑制增长的因素(下一季度再讨论),可能会降低投资组合其余部分的回报。

19. Perhaps more importantly, the resource squeeze, coupled with other growth-reducing factors (to be discussed next quarter), is likely to reduce the return from the balance of the portfolio.

GMO 四季度信 – 欢迎来到反乌托邦!– 2012 年 7 月 引言 自 15 个月前我写出关于资源短缺的信函《是时候醒来了》以来,我一直努力跟进最新细节,并补习自 1972 年具有开创意义的《增长的极限》出版以来的历史背景。令人不安的是,我研究得越深入,情况看起来就越糟糕:我们确实似乎正在耗尽廉价资源,而且无处不在一一甚至在中国也不例外一一这个问题都被低估了。其后果是,我们继续挥霍那些剩余的较低成本资源,并承受着由此带来的大量不必要的废弃物排放,尤其是二氧化碳,它已经开始对我们的天气稳定性产生显著影响,进而削弱我们生产足够粮食的能力。仅在过去五周内,玉米、小麦和大豆的价格就上涨了 30% 至 50%,达到并超过了 2008 年的危机水平,而这一次,尽管种植面积大幅增加。贫穷国家的社会反应不会落后太久。

GMO 4 Quarterly Letter – Welcome to Dystopia! – July 2012 Introduction In the 15 months since my letter on resource shortage, “Time to Wake Up,” I have tried to keep up on the current details and to catch up on the historical background since the ground-breaking “Limits to Growth” was published in 1972. Disturbingly, the more research I did the worse things looked: we indeed seem to be running out of cheap resources, and everywhere – even including China – the problem is underestimated. The consequences are that we continue to squander those lower-cost resources that remain and suffer from the large, unnecessary increase in the associated output of waste, particularly CO2 – which has already begun to have significant effects on our weather stability and, hence, our ability to grow enough food. The price of corn (maize), wheat, and soy in just the last five weeks rallied 30 to 50% to reach and exceed the 2008 crisis levels, this time despite enormously increased planting. Social reaction in poor countries will not be far behind.

去年信中曾指出,在大约 100 年的价格稳步下降之后,10 年前我们进入了一个资源价格持续上涨的新时代。现在看来,大约从 5 年前开始,我们也进入了一个针对几个最贫困国家的持续粮食危机时期。这种情况似乎很可能在可预见的未来持续下去。如果是这样,它将导致几个国家的社会结构崩溃,引发规模在现代(重大战争之外)史无前例的移民浪潮。在争夺资源(尤其是粮食,还有能源)的过程中,国家之间的关系也可能变得不稳定,给全球安全带来风险。中国对未来资源安全的担忧超过其他国家,会发现动用其日益增长的经济和军事实力尤其具有诱惑力。这种风险似乎也被各国政府忽视或低估,尽管包括美国在内的几个国家的军方似乎是例外。不需要为连任操心,军事领导人的时间视野远比政府其他部门长远,他们能够关注资源短缺(尤其是粮食和水)的长期后果,以及气温上升和天气不稳定性对国家安全与福祉日益增长的影响。

The New Food Crisis Last year’s letter showed that 10 years ago we entered a new era of rising resource prices after at least 100 years of steadily falling prices. It now appears that about five years ago we also entered a period of sustained food crisis for several of the poorest countries. This situation seems likely to continue for the indefinite future. If it does, it will cause the social structure of several countries to break down, resulting in waves of immigration on a scale unknown in modern times, outside of major wars. In the drive for resources, particularly food but also energy, country relationships are also likely to be destabilized, causing risks to global security. China, more concerned with future resource security than others, will find it particularly tempting to throw its increasing economic and military weight around. This risk also seems to be ignored or underestimated by national governments, although the military arms of several, including the U.S., seem to be exceptions. Not needing to be re-elected, military leaders have far longer time horizons than other branches of government and can afford to pay attention to both the long-term consequences of resource shortages – particularly food and water – as well as the growing effects of increasing temperatures and weather instability on the long-term security and well-being of their countries.

粮食压力带来的脆弱性很容易被证明,而且已经开始在我们眼皮底下上演。在发达国家,粮食只占我们总支出的 10% 或 12%。然而,对于包括埃及在内的几个较贫困国家来说,自 2002 年以来全球粮价飙升,粮食成本已升至其总支出 40% 甚至更高。(小麦是埃及以及北非其他地区关键的卡路里来源,他们大部分小麦依赖进口,因此直接暴露在全球价格波动之下。)过去 10 年全球粮食价格几乎翻了三倍。如果在未来 20 年再翻一番,即使对富裕国家来说也会是痛苦的现实,但简单的算术就能告诉你,对于那些粮食支出已占预算 40% 的较贫困国家来说,情况将变得多么不可能承受。甚至目前这 40% 的比重能否轻松承受也并不明确:据信粮价已经在阿拉伯之春中扮演了重要角色,尤其是在埃及。从现在开始,实际粮食价格的任何实质性上涨,都可能难以应对。

The vulnerabilities from food pressure can be easily demonstrated and are already beginning to play out beneath our noses. In developed countries, food accounts for only 10 or 12% of our total budget. For several poorer countries though, including Egypt, food costs have risen to 40% and above of their total expenditures following the surge in global grain prices since 2002. (Wheat is the critical source of calories in Egypt and the rest of North Africa and much of their wheat is imported so they are directly exposed to global price moves.) Global grain prices almost tripled in the last 10 years. If they were to double in the next 20 years it would be painful indeed even for rich countries, but simple arithmetic will show you how impossible the situation becomes for those poorer countries that start out with a 40% share of food in their budget. It is not even clear that the existing 40% share can be easily tolerated: grain prices are thought to have already played a substantial role in the Arab Spring, particularly in Egypt. Any material increases in real grain prices from here on are unlikely to be easily manageable.

埃及为何会陷入粮食困境?为什么把焦点放在埃及?因为出于地缘政治原因,美国将埃及视为一个多少还算重要的国家,而索马里或苏丹这类国家则很容易被忽视,也确实被忽视了。当拿破仑在 1800 年入侵时,埃及只有 300 万人口。如今,尼罗河畔有限的耕地挤满了 8400 万人!该国的人口年龄结构以及当前的计划生育做法(不算特别差,但也不算特别好)几乎可以保证,到 2050 年人口将膨胀到惊人的 1.4 亿!目前他们用自己生产的粮食养活约 5500 万人(这已经是很乐观的估计)。到 2050 年,如果行为非常明智,且社会能保持基本稳定,乐观估计他们也许能将这个数字提高到 8000 万。但今天,他们已有 250 亿美元的贸易逆差,主要用于进口粮食,尤其是小麦。凭借最近与国际货币基金组织的接触以及朋友的些许帮助,他们无疑能勉强渡过眼下这一年。但随着人口增长,贸易逆差也会扩大。随着时间推移,谁来为他们日益增长的进口粮食需求买单?我相信,简短的回答是:没有人。要想完整幸存,更不用说繁荣发展,他们需要的是受启发且可持续的转基因农业——按通常标准,他们的农业已经非常高产了——同时还需改变生育率。他们似乎没有时间等待因财富增长而导致的生育率自然下降。短期内,他们唯一可能藏着的王牌,或许就是未开发的常规石油和天然气,如果迅速开发,可能给他们换来比如十年或二十年的缓冲时间。如果你意识到有几个国家处于这种境地,甚至还有不少处境更糟,你就会明白全球稳定的外衣是多么脆弱地悬挂着。全球粮食危机并非遥远的未来前景,它似乎已经在路上,未来即使天气好转,似乎也只能给它带来一两年的喘息之机。粮食短缺是众多子因素的产物,每个子因素本身都是复杂议题。让我们从去年以来做一些更新和补充。

Egypt heads into food trouble Why focus on Egypt? Because it is treated as a more or less serious country by the U.S. for geopolitical reasons whereas Somalia or Sudan, for example, can be easily ignored and are. Egypt was home to three million people when Napoleon invaded in 1800. Today it crowds 84 million into the limited arable land around the River Nile! Its population age profile and its current family planning practices (which are not particularly bad, merely not particularly good) more or less guarantee that by 2050 the population will swell to a staggering 140 million! Today they feed about 55 million of their people with their own food (with the benefit of several doubts). By 2050, if they behave very sensibly and if their society stays reasonably stable, they might optimistically move this number up to 80 million. But today they already run a $25 billion trade deficit, basically importing food, critically, wheat. With their recent meetings with the IMF and a little help from their friends, no doubt they will finesse this recent year. But as the population grows so will their trade deficit. Who will pay for their increasing need for imported food as the years go by? I believe the short answer is no one. To survive in one piece, let alone thrive, they need inspired sustainable GMO 5 Quarterly Letter – Welcome to Dystopia! – July 2012 agriculture – it is already very productive by normal standards – and a shift in their fertility rate. They do not appear to have the time to wait for the typical reduction in fertility caused by advancing wealth. In the short term the only possible ace up their sleeve may be undeveloped conventional oil and gas, which might, if developed rapidly, be used to buy them, say, a decade or two of time. If you realize that several countries are in this position and quite a few are worse off, then you realize how perilously thin the veneer of global stability is. The global food crisis is not just a prospect for the distant future, it seems to be well on its way already and better weather in the future would seem unlikely to buy it more than a year or two of reprieve. Food scarcity is the product of many sub factors, each complex issues on their own. Let’s update since last year and expand a little on several of them.

水资源短缺水资源限制比我一年前认为的更为严峻。围绕流经不同国家的河流归属问题发生争吵甚至战争的可能性似乎更高了:埃塞俄比亚、苏丹和埃及之间的尼罗河;中国与印度、巴基斯坦、孟加拉国、柬埔寨以及几乎整个东南亚之间的喜马拉雅河流。过度抽取地下水问题也比我所描述的更为严重。大约 3 亿中国人和印度人(分别为 1.25 亿和 1.75 亿),以及许多其他国家的人,是依靠日益枯竭的含水层来养活。当这些含水层完全耗尽时,这或许多达 5 亿的人口将被迫依赖本已过载的地表水。与其他一些资源问题一样,有一个简单的解决方案——海水淡化。也与其他简单方案一样,它伴随一个可怕的缺点——超高成本。(新加坡一如既往地走在前列,正确地处理了其关键水问题:将其所有水的定价都基于下一个边际升的成本。独特的是,他们的下一升水来自海水淡化厂,因此他们支付的水价是其他沉浸在水价补贴中的世界的许多倍。即便如此,尽管他们对自己产的水采取了严厉政策,新加坡仍然受益于用于生产其大部分进口粮食的、价格极其低廉的水。而新加坡在一个非常重要的方面并不代表我们普遍面临的水问题:他们现在是附近最富有的人,人均收入超过 5 万美元(美国)!)老常态气候模式的改变似乎每周都在揭示水问题正在恶化:不可预测的季风(有时像今年一样减弱)、春季融雪减少,以及令人不安的常见严重干旱——我们只能希望这些干旱至少有一部分不会重演。

Water shortages Water constraints are worse than I thought a year ago. Squabbles or even wars over the division of rivers that flow through different countries seem more likely: Ethiopia, Sudan, and Egypt over the Nile; China and India, Pakistan, Bangladesh, Cambodia, and practically all of South East Asia over the flow of Himalayan rivers. Over pumping is also a bigger problem than I represented. About 300 million Chinese and Indians (125 and 175 million, respectively) among many others are fed through the use of declining aquifers. When entirely depleted, these perhaps then half a billion people will be thrown back onto already overstressed surface water. As with some other resource problems, there is an easy enough solution – desalination. And as with other easy solutions, it comes with a dreadful drawback – ultra high cost. (Singapore, ahead of the curve as usual, has addressed its critical water problem correctly: by pricing all of its water at the cost of the next marginal liter. Uniquely, their next liter of water is from desalination plants, so they are paying many multiples of the water price that is paid by the rest of the world, drowning as it is in subsidies. Even then, despite their Draconian policy with locally generated water, Singapore still benefits from the hugely underpriced water used to produce the majority of their food, which is imported. And Singapore is not representative of our problems with water in one very important way. They are now just about the richest people around with incomes per capita of more than $50,000 U.S.!) That changes from the old normal climate patterns exacerbate water problems seem to be revealed by the week: unpredictable monsoons (that as this year are sometimes weaker), less snow cover to run off in the spring, and unnervingly common severe droughts that we must hope are at least partly non-recurring.

土壤侵蚀至少侵蚀问题如我所料:可以通过大规模采用免耕农业来补救,但当前全球采用率不足 10%,能否足够迅速地(比如说 40 年内)普及,以防止一英寸都不可浪费的耕地的进一步关键性损失?在目前不变的耕作方式下,假设每年流失 1% 的土壤,数学计算很简单:我们将在 100 年内耗尽所有土壤并陷入饥荒。

Erosion Erosion, at least, is as I thought: it can be remedied through massive adoption of no-till agriculture, but with a starting point currently at under 10% globally, can it be adopted rapidly enough (say, in 40 years) to prevent further critical loss of arable land, every inch of which will be needed? With current unchanged practices and with 1% loss of soil per year the math at least is quite simple: we run through all of our soils in 100 years and starve.

潜在的肥料危机与可能的有机解决方案去年报告中最令人担忧的一个领域——磷肥和钾肥的耗尽风险——现在有所改善。这很幸运,因为我希望你还能记得当时讲述的故事有多么令人却步:钾(钾肥)和磷(磷酸盐)是所有生命物质生长所必需的;它们无法被制造或替代,并且是通过开采而不断耗竭的。这段叙述至今仍让我起鸡皮疙瘩!但好消息是,至少我们在一年前展示的那些储量依然可观,而且很可能还有相当多的未探明储量。因此,即使以我们目前这种挥霍的方式,我们仍有 100 年或更多的时间来醒悟。更重要的是,现有储量很有可能通过采用有机农业而大大延长,当有机农业运作良好时,可以将对额外钾肥和磷肥的需求降低到当前“大农业”所用量的极小部分。至少一些土壤专家认为,在最佳状态下,有机农业甚至可以完全解决这个问题。如果真是这样,那将是非常好的消息,因为如果继续沿用当前做法,即使能撑 200 年,我们也会耗尽陆上储量,并像土壤侵蚀一样,最终陷入极其糟糕的境地。不过,至少对于磷和钾来说,届时非常富有的人可以从海洋和海底获取它们。我的希望——实际上也是我的信念——是,随着长期肥料价格上涨(短期内当然可能大幅下跌),我们将被迫在有机农业方面变得更有创造力和更开放,从而永远不需要走海底回收这条最后的路。

Potential fertilizer crisis and possible organic solution The risk of phosphate and potash fertilizer running out is the one area in our report of last year that has improved. This is fortunate for you will remember, I hope, how intimidating was the story told then: potassium (potash) and phosphorus (phosphate) are necessary for the growth of all living matter; they cannot be made or substituted for and are mined and depleted. This recitation still gives me goose bumps! But the good news is that there are at least the substantial reserves we showed a year ago and it is likely that there is considerably more. Thus, even with our current prodigal ways, we have 100 years or more to see the light. More importantly there is a very good chance that existing reserves can be greatly stretched out by the adoption of organic farming, which, when done well, can reduce the need for extra doses of potash and phosphates to a very small fraction of that used in current “Big Ag.” Perhaps at its very best, say at least some soil experts, organic farming could totally remove the problem. If true, this would be very good news for if current practices continue, even if it took us 200 years, we would simply run through the onshore reserves and, as with erosion, end up very badly off indeed. Although, with phosphorus and potassium at least, the very rich at that point could retrieve them from the ocean and the ocean bed. My hope – and actually my belief – is that as fertilizer prices rise in the longer term (and they could certainly fall considerably in the short term) we would GMO 6 Quarterly Letter – Welcome to Dystopia! – July 2012 be forced to be more resourceful and open-minded about organic farming and then would never need the last resort of ocean-based recovery.

有机农业的一些利弊我们之前讨论过有机农业的本质。它旨在培育土壤微生物、昆虫、蠕虫和养分的复杂性,而不使用化学杀虫剂和农药,因为这些化学物质会消灭上述所有生物,只留下土壤,然后土壤完全依赖每年重新施用三大主要肥料,尤其是能源密集型氮肥。我们花了大量时间试图确定,转向有机农业在短期和中期内可能导致产量下降多少。主流观点(我并不是以此作为解决研究问题的方式,仅仅是传递事实和意见)是,全面转向有机农业将使谷物和大豆的即时产量下降 20% 到 30%。较高的降幅适用于灌溉土地,较低的降幅适用于雨养土地,因为有机土壤能保持更多水分,且在干旱条件下表现更好——这在当前环境下是一个非常有用的特性。然而,在长期的消耗战中,由于有机土壤能够保持质量甚至改善,并且比传统农业更能抵抗侵蚀,根据起始假设,天平会慢慢倾斜,几十年后可能会弥合大部分甚至全部产量差距。

Some pros and cons of organic farming We have talked before about the essence of organic farming. It is the nurturing of the soil’s complexity in microorganisms, insect life, worms, and nutrients without the use of chemical insecticides and pesticides, which have the effect of sterilizing all of the above, leaving just dirt, which is then completely dependent on the new application of all three major fertilizers each year, especially the energy-intensive nitrogen. We have spent considerable time trying to determine the possible reduction in output in the short and intermediate term that you might get from moving to organic farming. The majority opinion (I am not arguing for this as a way of settling research issues, merely passing on facts and opinions) is that immediate output of grains and soy would be reduced by 20 to 30% by moving to fully organic farming. The higher range is applied to irrigated land and the lower range to rain-fed land because organic soil retains more moisture and holds up better as conditions get drier – a very useful trait these days. In a long-term war of attrition, though, because organic soil holds up in quality and even improves, and because it resists erosion better than standard farming, the equation shifts and in several decades may close much or all of the gap, given the starting assumptions.

然而,事情更复杂的是,一些有机农业研究人员认为,当有机农业做得好——通过反复试验和科学研究进行精细调整——它能够(并且在他们超过 20 年的测试中已经)达到与当前标准耕作方式相当的产量。由于有机农业尤其能大幅减少日益昂贵的化肥使用,即使没有目前为少量有机谷物支付的相当可观的溢价,这种耕作也同样可以实现盈利。但这一论点的关键弱点在于,这种耕作方式需要投入大量脑力:它必须针对每种作物和每种土壤类型进行精细调整,而现有的知识体系、可咨询的建议、有经验的操作者,甚至良好的培训项目都非常匮乏。将最好的有机农业与普通的传统农业相比,显然是不公平的。而且,你如何说服典型的农民——一个 60 岁的人——去采用一种复杂得多的系统,这种系统因此至少在初期风险更高、更难获得保险?坏消息是,要实现 100% 有机农业是一项艰巨的任务,需要几十年的努力,包括政府的参与和大量研究。更糟糕的消息是,这是一项绝无替代方案的任务,因为长期来看,维持现状注定会导致如前所述的钾和磷资源枯竭,并最终走向极其糟糕的结局。不过,好消息是,这项至关重要的任务毫无疑问是可以完成的,一旦完成,将首次为粮食生产的可持续基础提供保障。

But to make matters more complicated, some researchers in organic farming3 believe that when organic farming is done well – fine-tuned by both trial and error and scientific research – it can (and has in their 20+ year tests) reach parity with current standard-practice farming. Because the use of increasingly expensive fertilizers in particular is much reduced with organic practices, such farming can be equally profitable also, even without the considerable premium now paid for the modest quantities of organic grain produced. But the key weakness in this argument is the brain intensity required of this kind of farming: it has to be fine-tuned for each crop and each type of soil and there is a skimpy body of existing knowledge, available advice, experienced practitioners, or even good training programs. To compare the best organic farming with ordinary conventional farming is obviously an unfair comparison. And how would you persuade the typical farmer, a 60-year-old, to adopt a much more complex system that is therefore riskier at least initially and harder to insure? The bad news is that to gear up for 100% organic farming is a herculean task that will take decades of effort, including government participation and considerable research. The worse news is that this is a task for which there is absolutely no alternative in the long run for the status quo will guarantee that we will run out of potash and phosphorus as mentioned earlier and eventually come to a very bad end. The good news, though, is that this vital job can without doubt be done and when done would guarantee for the first time a sustainable basis of food production.

摩洛哥难题:肥料领域的尾刺。关于磷矿储量,去年我曾提及长期供应的另一个隐患——资源极度集中在摩洛哥。后续研究证实,基于目前已知储量,全球优质低成本磷矿的 70% 掌握在摩洛哥手中,这一比例远超整个欧佩克(OPEC)的石油份额。(沙特石油大臣最美好的梦想,就是能拥有这样的地位,而不是面对那么多吵嚷不休的同事。)因此,即便我们继续维持当前极度浪费的开采方式,磷矿储量或许还能支撑 200 年。但若果真如此,摩洛哥——它已日益被视为价格制定者——将在短短几十年内掌握人类历史上最重要的准垄断地位!我认为,我们至少应为磷价持续上涨做好充分准备,而这一趋势将逐步把成本优势转向更节俭的有机农业。

The Moroccan quandary: a sting in the fertilizer tail On the topic of phosphate reserves, last year I mentioned another snag with long-term availability – the extreme concentration of resources in Morocco. Follow-up research confirms that given currently known reserves, as much as 70% of all high-quality, low-cost reserves are in their hands, a number far in excess of the whole of OPEC collectively for oil. (The best dream of the Saudi oil minister is that they would be in that position rather than having so many obstreperous colleagues to deal with.) So, yes, we may have up to 200 years of phosphate reserves even if we continue in our present ultra-wasteful ways. But if we do so, Morocco, already increasingly considered to be the price setter, will have in a relatively few decades the most important quasi-monopoly in the history of man! We should at the very least be very prepared, I believe, for a steady rise in the price of phosphates, and how that will steadily shift the cost benefits toward the more frugal organic farming.

谷物产量增速放缓。一年前我曾提到,谷物每年每英亩产量的增速正在下降。这一增速从绿色革命时期(例如 1970 年)惊人的每年 3.5%,降至 2010 年依然可观的 1.5%。我当时指出,这一增速已令人不安地接近全球人口增速。好消息是,罗代尔研究所(Rodale Institute)对此有研究。

Grain productivity gains slow A year ago I mentioned the declining rate of increases in yearly productivity per acre for grains. It had fallen from an astonishing 3.5% a year in the Green Revolution, say, 1970, to a still considerable 1.5% in 2010. This rate of increase, I pointed out, was disturbingly close to the same as the growth in global population. The good news here, 3  Rodale Institute.

GMO 7 季度信函——欢迎来到反乌托邦!——2012 年 7 月,我们更新的内容中,几乎可以肯定的是,人口增长将继续放缓。事实上,每年新生婴儿的数量已经趋于平稳,全球人口之所以还在增长,主要是因为早期出生的婴儿群体(比如现在 60 岁左右的那代人)人数远少于近期的婴儿群体。这并非因为他们已经去世,而主要是因为他们从未出生过。随着这些人数更多、但已趋于稳定的新婴儿群体逐渐年长,80 年后(即 2090 年),全球人口将接近 90 亿到 100 亿的峰值。还有一个很大的可能性是,生育率(繁殖率)将在目前的稳定水平基础上继续下降,出生人数也将开始下降(即使没有长期粮食短缺的潜在推波助澜)。而且,它最好真的下降,因为目前我们已远超地球的长期承载能力。坏消息是:首先,谷物产量的增长也可能放缓;其次,随着发展中国家迅速壮大的中产阶级持续要求更多肉类——目前每磅精牛肉需要消耗 30 磅谷物!——潜在供应与未来需求之间的安全裕度将消失。事实上,这个裕度可能已经消失了。

GMO 7 Quarterly Letter – Welcome to Dystopia! – July 2012 as we update, is the near certainty that population growth will continue to slow. Indeed, the number of new babies born each year has already leveled off and the global population continues to grow only because earlier cohorts of babies who are now, say, 60-year-olds, were much smaller than more recent ones. This is not because they have died off, but primarily because they had never been born. As the new, larger but now stable cohorts of babies grow old, in 80 years the population approaches a peak of 9 to 10 billion (in 2090). There is also a good probability that fertility (reproduction rate) will continue to decline beyond the current stabilization and that the number of births will start to decline (even without possible help from chronic food scarcity). And it had better do so, for currently we are well beyond the long-term carrying capacity of our planet. The bad news is first that the increases in grain productivity are also likely to decline, and second that as the very rapidly increasing middle class of the developing world continues to demand more meat – one pound of dressed beef currently replaces 30 pounds of grain! – the safety margin between potential supply and future demand would disappear. Indeed, it may have disappeared already.

谷物生产率中有一个出人意料的问题,被称为“玻璃天花板”。每个物种都存在理论上的极限。一个现实中的例子是赛马:人类为追求速度而培育赛马已有 5000 多年历史——对部落首领来说,没有什么比一匹快马更能彰显威权了!然而,赛马显然已经触及了天花板。尽管马匹培育者费尽心机、投入巨大,如今赛马的速度相比 20 世纪 20 年代,并没有出现可测量的、可靠的提升。它们尝试跑得更快,结果摔断腿的次数更多,得到的化学刺激也更多,但就是无法再快一步。令人不安的是,有迹象表明谷物也可能正在发生同样的事情。不出意料,你会去那些每英亩产量最高的农民那里寻找这种玻璃天花板——之所以叫这个名字,是因为在撞上它之前你根本看不到它。图表 1 显示了英国、法国和德国的小麦每英亩产量,以及日本的水稻产量。这些直接供人类食用的两种最重要谷物的顶级产区,在过去十年甚至更长的时间里,未能提高生产率。这就把大幅增产的压力转嫁给了产量较低的生产者,而理论上,这些生产者确实有更大的改进空间。不过,要记住一点:许多产量偏低的耕地,长期以来或多或少一直表现不佳。如果容易改进,早就改进了。然而,资本主义有一些伟大的优点:其中之一就是高价格很可能是一切老师中最好的那一位。

Glass ceiling In grain productivity there is an unexpected problem known as the “glass ceiling.” Each species has a theoretical limit. A real life example is that of race horses, bred for over 5,000 years for speed – nothing was more macho for a chief than a fast horse! Well, horses have apparently reached a ceiling. Despite the ingenuity and expenditures of horse breeders, horses do not run measurably or dependably faster today than they did in the 1920s. They break more legs trying and they get more chemical encouragement, but they just can’t run any faster. Disturbingly, there are signs that this may be happening with grains. Not surprisingly, you would look for this glass ceiling – it is called this because you can’t see it coming until you get there – amongst the farmers who have the greatest output per acre. Exhibit 1 shows the yield per acre for wheat in England, France, and Germany and the yield for rice in Japan. These top-producing countries for the two most important cereals for direct human consumption have failed in the last 10 or more years to increase productivity. This puts the burden of major increased production on the poorer producers, and there is indeed on paper much more room for improvement. It is important to remember, though, that many of these under-producing acres have been suboptimal more or less forever. If it were easy to correct, it would have been corrected. Yet capitalism has some great virtues: one of them is that high price is probably the best teacher of all.

It was the major reason for the Green Revolution: first, selecting seeds that could utilize more inputs of fertilizers and turn them into more plant growth, and second, providing them with the extra fertilizer. But beyond a certain point more fertilizer does not improve returns. It does, on the other hand, do increasing environmental damage, mainly by over fertilizing waterways and helping to create dead zones near river mouths. There are still big areas, particularly in Africa, that could process more fertilizer, but in general they are already priced out of the fertilizer market. The net result is that we are deep into diminishing returns with fertilizer and can hope for only modest and decreasing help from this source in the future for increasing the productivity of grain.

气候变化对谷物生产的负面影响

过去我曾认为“气候变化”是“全球变暖”的一个软弱、逃避现实的替代说法,但现在我不这么认为了,因为极端天气——干旱、洪水和极端高温的爆发——对粮食生产的破坏力远大于全球平均气温的稳步上升。三个种植季以前,干旱和洪水的严重程度已经突破了历史纪录,我当时预测情况会有所改善。然而,基于以往的天气分布模式,极端天气事件发生的概率低得不可思议,但严重的天气事件却接连又持续了两个种植季。正如去年详细讨论过的资源价格问题,当概率达到数千比一时,通常意味着旧模型已经失效。所以,在资源问题上,资源价格持续下跌的旧模式被打破了,一个截然不同的新时代已经开启。同样,连续三年出现如此灾难性天气的概率实在太高,以至于难以令人置信;更安全的假设是,旧的天气模式已经失效,一个气温上升、干旱和洪灾更严重的新时代已经降临。世界各地的城市正在纷纷打破高温纪录,今年 3 月至 5 月是美国有史以来最热的月份。与资源价格上涨这个同样令人不快的现实一样,这个新的、更不理想的气候状况也必须被接受并加以适应。再次重申,我们适应得越快,处境就会越好。保险等几个行业已经在深入研究新的后果。农业也必须进行调整,而不仅仅是适应价格上涨。凭借技能、研究,尤其是试错,农民将根据不断变化的天气调整他们种植的作物类型和玉米种子品种。我毫不怀疑他们将减轻干旱和洪灾加剧带来的一些最坏影响。但最严重的冲击还在遥远的未来:谷物是在数千年异常温和且稳定的气候中(即,在以数十万年计的尺度上温和)进化而来的;过去几百年的选种育种也是在那种温和的环境中进行的。谷物就是不喜欢非常高的温度。到本世纪末,政府间气候变化专门委员会(IPCC)预测,全球气温的预期上升将使传统产区的谷物生产力降低 20% 到 40%——考虑到其他问题,这个数字高得令人揪心。是的,北部地区的气候将受益(因此加拿大再次看起来像一个好盟友),但世界上将有更多一流谷物产区消亡,而非增加。而且,千万不要以为科学家们是拿着邪恶基金会薪水、危言耸听的夸大者,就像右翼智库让你相信的那样。迄今为止的记录表明,他们一直是在谨慎地低估问题。绝大多数科学家都不喜欢处于聚光灯下,并且极其害怕被指责为夸大其词——在学术界,这是一项仅次于伪造数据的严重罪行。这些谨慎的科学家们忘记的是(这一切都是由职业风险驱动的,就像机构投资一样),在这种独特的情况下,低估才是危险的!将科学清晰地置于公共领域——这一任务至今完全失败——留给了少数勇敢且敢于直言不讳的科学家。私下里与气候研究科学家交谈,你会发现他们认为几乎所有事情都比他们担心的更糟,并且正在危险地加速。一个明显的例子是北极冰盖的融化,到 2005 年,其夏末的覆盖面积已比近 30 年的平均水平减少了 30%。今天它处于的水平(上个月是有记录以来 6 月份冰盖最少的一次)是 15 年前对 2050 年的预测!去年有数十艘船只在北极水域进行了商业航行,而在 2008 年之前,从未有船只到过那里。一个危险的正反馈循环正在起作用:深色的海洋吸收热量,而冰层则反射热量,因此海水变暖,更多的冰融化。其他潜在更危险的循环也可能开始:冻土带蕴藏着大量的甲烷,而甲烷的作用就像增压版的二氧化碳。它使空气变暖,导致更多冻土带融化,如此循环往复。对于对温度变化极其敏感的农业来说,世界已经变得非常危险。如今没有任何安全边际来吸收意外的冲击,正如我们正在中西部持续上演的全球危机中所看到的那样。

The negative effect of climate change on grain production I used to think that “climate change” was a weak, evasive version of “global warming” but not anymore, for weather extremes – drought, floods, and bursts of extreme heat – have turned out to be more devastating for food production than the steady rise in average global temperatures. Droughts and floods were off-the-scale awful three growing seasons ago, and I forecasted some improvement. But with impossibly low odds – based on the previous weather distribution pattern – severe weather events kept going for two more growing seasons. Just as with resource prices, detailed last year, when the odds get into the scores of thousands to one, it is usually because the old model is broken. So in the resource case, the old model of declining resource prices was broken and a new, very different era had begun. Similarly, the odds of three such disastrous years together are just too high to be easily believed and the much safer assumption is that the old weather model is broken and a new era of rising temperature and more severe droughts and floods is upon us. All-time heat records in cities across the world are falling like flies and the months of March through May this year were the hottest in U.S. history. As with the equally unpleasant fact of rising resource prices, this new, less desirable climate has to be accepted and adjusted to. Once again, the faster we do it, the better off we will be. Several industries like insurance are already deep into the study of the new consequences. Farming must also adjust, and not just to the rising prices. With skill, research, and, above all, trial and error, farmers will adjust the type of crop and the type of corn seed they use to the changing weather. And I have no doubt that they will mitigate some of the worst effects of increased droughts and floods. But the worst shock lies out quite far in the future: grains have developed over many thousands of years in an unusually moderate and stable climate (moderate, that is, over a scale of hundreds of thousands of years); and selective breeding of the last few hundred years also was done in that moderate environment. Grains simply do not like very high temperatures. By the end of the century, the expected rise in temperature globally is projected by the IPCC to reduce the productivity of grain in traditional areas by 20% to 40% – numbers so high that the heart sinks given the other problems. Yes, northern climates will benefit (so Canada once again looks like a good ally) but more world-class grain land will be lost than is gained. And do not for a second think that the scientists can be dismissed as exaggerators in the pay of evil foundations as right-wing think tanks would have you believe. The record so far has been one of timid underestimation. Much the majority of scientists hate being in the limelight and live in dread of the accusation of the taint of exaggeration, so severe a crime in the academic world that it is second only to faking data. What the timid scientists forget (this is all driven by career risk just as with institutional investing) is that in this unique case it is underestimating that is dangerous! To put the science clearly in the public domain – a task so far totally failed at – is left to a brave handful of scientists willing to be outspoken. Talk privately to scientists involved in climate research and you find that they believe that almost everything is worse than they feared and accelerating dangerously. A clear example is in the melting of the Northern ice, now down in late summer by 30% from its recent 30-year average to 2005. It is at a level today (and last month was the least ice cover of any June ever) that was forecast 15 years ago for 2050! Dozens of ships last year made commercial voyages across the Northern waters where none had ever gone before 2008. A dangerously reinforcing cycle is at work: the dark ocean absorbs heat where ice reflects it, so the water warms and more ice melts. Other potentially more dangerous loops might also start: the Tundra contains vast methane reserves and methane acts like supercharged CO2. It warms the air and more Tundra melts and so on. For agriculture, which is very sensitive indeed to temperature shifts, it has GMO 9 Quarterly Letter – Welcome to Dystopia! – July 2012 become a very dangerous world. There is now no safety margin to absorb unexpected hits as we are seeing in the global crisis playing out in the Midwest today.

关于粮食的一点希望

数百万年来,一个日益壮大的禾本科植物亚群(如今已占到 43%)发生了一种突变式的进化,在利用氮、水和太阳能方面的效率显著提高。绝大多数禾本科植物是相对低效的光合作用者,属于植物学家所称的 C3 家族。不幸的是,这个家族包括水稻和小麦,这两种人类最重要的食用谷物。而那个发生突变的较小家族,被称为 C4,幸运地包括玉米和甘蔗。这意味着,在它们目前的基因条件下,无论你多么努力地种植小麦和水稻,其产量永远也不会超过玉米的一半。

The one piece of hopeful news for food Over millions of years, an increasing minority of grass species – now up to 43% – have made a mutating jump into much greater efficiency in processing nitrogen, water, and the sun’s energy. The majority of grasses are relatively inefficient photosynthesizers and belong to the family botanists known as C3. This group unfortunately includes rice and wheat, the two most important grains for human consumption. The smaller family that has made the jump, known as C4, luckily includes corn (maize) and sugar cane. Among other things, this means that under their present genetic circumstances, however hard you try to grow wheat and rice you will never get more than about half of the output of corn.

到目前为止,尽管谷物基因工程在改变其他种子特性方面取得了成功,但在提高实际产量方面却收效甚微或根本没有。然而,根据邱园千年种子库的说法,种子工程的“圣杯”是将高效的 C4 基因植入低效的 C3 禾本科植物中。据认为,这可以将小麦和其他 C3 植物的生产力提高高达 50%!这项工作进展顺利,参与的科学家将其描述为“简单的工程”,我希望他们不会过于傲慢。他们相信这项工作将在 20 年内完成。即使需要 30 或 40 年,它也将是那种罕见的东西——一个游戏规则改变者。它可以养活数以亿计的额外人口,为人口更平稳地减少(而非目前这种可能性较大的情况)赢得时间。

Up until now, genetic engineering of grains has shown little or no increases in actual yield, despite success in changing other seed characteristics. Nevertheless the “Holy Grail” of seed engineering, according to the Millennium Seed Bank of Kew Gardens, is to engineer efficient C4 genes into inefficient C3 grasses. This, it is thought, could increase productivity of wheat and other C3 plants by up to 50%! The work is apparently going well and has been described as “simply engineering” by involved scientists, without, I hope, too much hubris. They believe it will be done in less than 20 years. Even if it is done in 30 or 40 years, it would be that rare bird – a game changer. Hundreds of millions more could be fed, buying time for a more graceful population decline than is currently likely.

2050 年的粮食前景

关于这一主题的文献一致认为,到 2050 年,全球粮食产量需要“大幅”增长。过去几年中最常用的两个数字(几乎成了陈词滥调)是,到 2050 年,我们需要将粮食产量翻一番,或增加 70%,才能满足预期的需求。最近,联合国消息来源估计,我们可能能够将粮食供应增加 60%。

Food prospects for 2050 The literature on this topic agrees that a very large increase in global food production is “needed” by 2050. The two most commonly used numbers in the last several years (almost clichés) are that we either need to double food production or to increase it by 70% by 2050 to keep up with expected demand. Recently, U.N. sources have estimated that we are likely to be able to increase food supply by 60%.

鉴于农业面临的诸多问题,毫不奇怪,我认为即使是较低的联合国预测也极不可能实现,而较高的数字则完全是空中楼阁。是的,为了满足到 2050 年人口实际增长 30%(达到 90 亿以上)以及预期的肉类消费增长,增产 60% 是必要的。但考虑到已经描述的所有困难,这根本不会发生,至少不可能持续地发生。(我知道这类言论总爱回来困扰人们,但在这个问题上,我期待一个不受困扰的人生,甚至来世也是如此。)来自不断增长的人口的日益增长的需求将在 2050 年存在,尽管如果一些较大的穷国开始崩溃,人口是否会完整地达到 90 亿以上还远未确定。但这就是市场先生介入的地方:在粮食供应达到额外 60% 之前很久,不断上涨的价格就已经使数亿人买不起食物。为了平衡收支,必须采取一系列严肃(但仍然可行)的步骤。首先,全世界必须比“翻一番”预测中假设的消费更少的肉类。明智的政府会鼓励这样做:穷国减少日益昂贵的谷物和豆粕进口,富国遏制从美国蔓延开来的肥胖流行病,这种流行病威胁着每个感染它的国家的长期医疗健康成本。(如果有什么问题需要“保姆国家”出手,那就是这个!)随着人口老龄化,一波额外的医疗费用可能会压垮几个国家的财政预算。其次,从农田到餐桌的全球粮食浪费率高达惊人的三分之一。(一些消息来源称这个数字要高得多。)如果我们想有机会勉强支撑到 2050 年,就必须大幅减少这种浪费。第三,主要粮食生产国必须更加认真地投资于可持续生产,增加对灌溉、农业教育和研究的投资。采取认真措施降低燃料的长期成本,当然,保护气候免于持续恶化也至关重要。但减少粮食供需不平衡的主要因素可能再次是价格:更多的穷人将减少食量,而一些穷人,令人遗憾地,将根本吃不上东西。

Given the long litany of farming problems, it will come as no surprise that I believe that even the lower U.N. forecast is highly unlikely to be met and that the higher numbers are complete pie in the sky. Yes, a 60% increase is necessary to meet the realistically forecast 30% increase in population to 9 billion+ together with the anticipated increase in meat consumption. But given all of the difficulties already described, it is just not going to happen, at least on any sustained basis. (I know statements like this love to come back and haunt people but on this one I look forward to an unhaunted life, and afterlife, for that matter.) The increasing demand from a growing population will be there in 2050, although it is far from certain that it will be the full 9 billion+ if some large poorer countries begin to unravel. But this is where Mr. Market intrudes: long before an extra 60% in food supply is reached, rising prices will have made food too expensive for hundreds of millions. To balance the books, a series of serious (but still doable) steps must occur. First, the entire world must consume less meat than is assumed in the estimate of a doubling. Sensible governments will encourage it: poor countries to reduce increasingly expensive grain and soy imports and rich countries to contain the epidemic of obesity that is sweeping outwards from the U.S. and threatening the long-term health costs of each country that catches it. (If any issue needs a “nanny state” feature this is it!) With an aging population, a wave of extra health costs would be likely to break several national budgets. Second, food wastage runs – from farm to stomachs – at a shocking one-third globally. (Some sources claim the number is considerably higher.) This waste must be much reduced if we mean to have any chance at all of muddling through to 2050. Third, major food-producing countries will have to be more serious about investing more in sustainable production with increased investments in irrigation, farm education, and research. Taking serious steps to lower the longer-term costs of fuel and, of course, protecting against continued deterioration in the climate will also be vital. But the main contributor to reducing the food imbalance between supply and demand is once again likely to be price: more of the poor will eat less and some, regrettably, will eat nothing.

为了应对粮食和其他资源问题,发达国家可以尽早采取果断行动,节约使用并提高效率。无疑会有一点行动,但对于富裕国家来说,价格信号仍然相当微弱。我们有很大的惯性。总的来说,在这个问题上我们的领导力很差——只有斯堪的纳维亚国家和中国可能勉强及格。而在美国,我们一直被灌输一切都会好起来的信息。因此,我们对这些正在发展的问题的集体应对不足,将导致资源价格,特别是粮食价格,出现不必要的急剧上涨。无意之中,却又是轻率地,我们将导致,并已经在导致,穷国出现不必要的营养不良和饥饿,这种情况只会变得更糟。

To deal with food and other resource problems, developed countries could respond early and decisively to economize on use and improve efficiency. There will no doubt be a little of this, but the price signal is still quite faint for GMO 10 Quarterly Letter – Welcome to Dystopia! – July 2012 the affluent countries. We have enormous inertia. We are in general badly led on this issue – only Scandinavian countries and China might get even a passing grade. And we in the U.S. are constantly told that all will be just fine. So our collective under-response to these developing problems will cause unnecessarily sharp rises in the prices of resources, particularly food. Unintentionally, but thoughtlessly, we will cause and already are causing, unnecessary malnourishment and starvation in the poorer countries, which is only bound to get worse.

当然,他们——穷国——应该以更加紧迫的态度来应对。特别是,可以更积极地抑制人口增长。让女性接受教育并提供计划生育服务在一些国家效果良好。然而,每年仍有 8000 万例意外怀孕,往往就发生在那些粮食前景最为危险的国。但是,这些国家中有多少会在问题的时间范围内做出强有力的反应呢?随着粮食和能源状况恶化,它们会严重削弱经济的其余部分以及政府和社会的应对能力。最终,随着国家崩溃,它们将失去采取果断行动的一切希望。

Of course they – the poorer countries – should respond with much increased urgency. Population growth in particular could be more actively discouraged. Educating women and making family planning available have worked well in some countries. Yet there are still 80 million unwanted conceptions a year, often in those very countries whose food future is most perilous. But will many of these countries respond vigorously within the time scale of the problem? As food and energy conditions worsen, they seriously weaken the remainder of the economy and the ability of government and society to respond. Finally, as states fail, they lose all hope for determined action.

北美堡垒对于北美堡垒(不含墨西哥),或者我们可以称之为“加美尼亚”,这些问题相对遥远。当玉米歉收时,我们担心的是农民的收入,而不是饥荒。从长远来看,事实是,将加美尼亚视为一个整体,其处境相对于地球上其他地区的平均水平而言,几乎好得令人难以想象。仅美国的人均地表水就是中国的 5 倍,人均可耕地是中国的 7 倍!而加拿大甚至更多。我们是粮食的极大出口国。加拿大,我们非常、非常好的朋友(拜托了!),拥有巨大的钾盐矿床,而美国也拥有数量可观的磷酸盐,尽管这可能是我们最薄弱的一环。(颇具讽刺意味的是,我们可能一直在以外国人需求的最高速度出口这种相对有限的资源,而就在上上个月,美国第二大磷酸盐矿在佛罗里达州因储量耗尽而关闭。)在处理这类问题时——如果你愿意,可以说这是一场全球公地悲剧——很难让赢家过度担心输家。而我们,这些富国,并不担心,而且很可能在可预见的未来也不会担心,因为要对这个问题有广泛的认识,需要深刻的文化和伦理变革。我们这种无忧无虑且漫不经心的态度,一个完美的象征便是我们对玉米乙醇的政策。这是一种间接的、后门式的补贴(伪装成强制要求),受益者是那些如今在粮价大幅上涨背景下、与正常情况相比已经相对富裕的农民。尽管与甘蔗和数十种其他作物相比,玉米作为乙醇原料的效率几乎荒谬地低下,但我们仍有 40% 的玉米作物——全球最重要的出口作物——被转离了食品用途。如果往一辆 SUV 里加满一箱纯乙醇(是的,我知道在美国是混合使用,但请容忍我这么说),它所取代的食物热量足以养活一个印度农民一整年!如果营养不良问题加剧(我认为会如此),却还坚持这种愚蠢的做法,客气点说,就是不够慷慨:它推高了玉米价格,使较贫穷国家的人们难以负担,并通过替代效应,推高了所有谷物价格。(全球玉米和小麦价格在短短两个月内已暴涨超过 40%。)我们的乙醇政策在道德层面上,正变得与枪杀一些贫穷的印度农民无异。只是死亡来得更缓慢、更痛苦。

Fortress North America For Fortress North America (ex-Mexico), or what we might call Canamerica, these problems are relatively remote. When corn crops fail we worry about farmers’ income, not about starvation. In the long run, the truth is that Canamerica seen as a unit is in an almost unimaginably superior position to the average of the rest of our planet. Per capita, the U.S. alone has five times the surface water and seven times the arable land of China! And Canada has even more. We are very large exporters of food. Canada, our very, very good friends (please!) has huge deposits of potash and the U.S. has a respectable amount of phosphate, although that probably is our weakest link. (Ironically, perhaps, we have been exporting this relatively limited resource as fast as foreigners demand it and the second largest mine just closed in Florida, reserves exhausted, the month before last.) It is hard when dealing with this kind of problem, which is a tragedy of the global commons if you will, to get the winners to worry too much about the losers. And we, the rich countries, do not worry and probably will not as far as the eye can see, for such a broad recognition of the problem would require a profound cultural and ethical change. A perfect symbol of our carefree and careless attitude is in our policy toward corn-based ethanol. It is an indirect, back-door subsidy (disguised as a mandated requirement) for farmers who today, with much higher crop prices, are already relatively well-off compared to normal. Despite corn being almost ludicrously inefficient as an ethanol input compared to sugar cane and scores of other plants, 40% of our corn crop – the most important one for global exports – is diverted away from food uses. If one single tankful of pure ethanol were put into an SUV (yes, I know it’s a mix in the U.S., but humor me) it displaces enough food calories to feed one Indian farmer for one year! To persist in such folly if malnutrition increases, as I think it will, would be, to be polite, ungenerous: it pushes the price of corn away from affordability in poorer countries and, through substitution, it raises all grain prices. (The global corn and wheat prices have jumped over 40% in just two months.) Our ethanol policy is becoming the moral equivalent of shooting some poor Indian farmers. Death just comes more slowly and painfully.

再问一次,为什么特别提印度农民?因为据《彭博社》上月报道,根据印度国家抽样调查办公室的数据,印度农民的人均每日热量摄入已从 1973 年的峰值 2266 卡路里,下降到去年的 2020 卡路里。而城市居民的人均每日热量摄入,则从大约 2100 卡路里下降到了 1900 卡路里。同一报道还指出,印度人均粮食消费量已从 1990 年代初的 177 公斤下降到 2004 年的 153 公斤(大致相当于 1934 年的水平!)。如果你还想让人们干好一天活,那这样的降幅在未来 30 年里可不能再重演了!而且,匪夷所思的是,这些下降恰恰发生在城市居民官方平均收入翻了一倍多的时期。显然,对于进城务工者来说,农村里免费的棚屋变成了城里昂贵的棚屋。现在他得为做饭的燃料和上班的通勤掏钱。他还得买食物,这些食物从乡下运进城来运费昂贵,沿途还有“只有印度才有的”惊人浪费、太多中间商,于是,行了,按 GDP 衡量他富裕了一倍,却买不起足够的食物。更令人震惊的是,印度三岁以下儿童中有超过 40% 营养不良、体重不足,这个比例比大多数甚至更贫穷的非洲国家还要糟糕。这个数字威胁着印度的未来。而与此同时,印度新增的百万富翁数量却在惊人地增长。好吧,这对尼赫鲁大学的乌莎·帕特奈克来说倒是不错。

Once again, why single out Indian farmers? Because it was reported last month in Bloomberg that the caloric intake of the average Indian farmer had dropped from a high of 2,266 a day in 1973 to 2,020 last year according to their National Sample Survey Office. And for city dwellers the average had dropped from approximately 2,100 to 1,900. It was also reported4 that per capita consumption of food grains had fallen from 177kg in the early 1990s to 153kg in 2004 (about 1934 levels!). These are not drops you would want to repeat in the next 30 years if you wanted a good day’s work! And, perversely, these declines occurred while the official average income of urban dwellers more than doubled. Apparently a free hut in the country became an expensive hut in town for the migrant. Now he has to pay for cooking fuel and transportation to work. And he has to buy food, expensively shipped in from the country, with incredible “only in India” quantities of wastage, and too many middle men and, bingo, he is twice as rich as measured by GDP but cannot afford to buy sufficient food. Even more shocking, over 40% of India’s children under the age of three are undernourished and underweight, a ratio worse than most even poorer African countries. This is a number that threatens India’s future. And meanwhile there is an amazing increase in new Indian millionaires. Well, good for 4  Utsa Patnaik of Jawaharlal Nehru University.

GMO 11 季度信函 – 欢迎来到反乌托邦! – 2012 年 7 月 但给穷人更多食物,同时大幅减少浪费、粮食盗窃和彻头彻尾的腐败,将是个好主意。不过,这个故事的要点,是为了强调一个观点:这场危机现在正在上演!

GMO 11 Quarterly Letter – Welcome to Dystopia! – July 2012 them. But a little more food for the poor, and a lot less waste and food theft and outright corruption would be a good idea. The point of this story, though, is to reinforce a point: this crisis is playing out now!

接下来说说金属(我猜你们早就在等这个结尾了)。在近期,情况其实没有那么严重——由于全球经济日益疲软,价格下跌的可能性大于上涨。而从 20 到 40 年的长期看,情况也不像粮食或能源那么糟糕,因为金属储量相当可观(大约还有 50 到 100 年),而且存在大量替代空间。这再次印证了经济学家们喜欢挂在嘴边的那句话:"只是价格问题"。优质资源在枯竭,价格在上涨,但依我看,这还不至于像能源和粮食那样严重影响经济增长——它充其量也只是给增长制造了点小小的障碍,是另外两个更紧迫制约因素之外的又一个叠加项。

Metal To move on (at long last, I can hear you say) in our update to metals, the story is not really as serious in the near term, where price declines are more likely than rises because of growing weakness in the global economy. Nor is it as bad in the 20- to 40-year horizon as food or energy for there are quite a lot of reserves (let’s say about 50-100 years) and there is substantial ability to substitute. Again it is “just a question of price” as economists like to say about everything. High-quality resources are depleted and prices rise, but in my opinion not enough to materially affect economic growth as it does with energy and food, but it is certainly a modest hindrance to growth and one that is an add-on to the other two more immediate constraints.

不过,金属的大问题出现在长期和超长期,届时金属的可获得性将成为最棘手的难题。因为金属中的熵是无情的。无论我们多么努力地回收,无论实物产出的增长多么缓慢,金属仍会从我们指间慢慢流失。它们永远无法被替代。如果我们的行为非常得当,金属价格会缓慢上涨;如果我们的行为不那么得当——这看起来可能性大得多——那么金属价格就会涨得更快。直到有一天,价格压力迫使我们表现得更好:近乎百分之百地回收,并去那些富饶的 20 世纪垃圾堆里翻找。

The big problem with metals, though, comes in the long term and the very long term where metal availability becomes the most intractable problem of all. For entropy in metals is merciless. However hard we try to recycle and however low our growth in physical output, metals will still slip slowly through our fingers. They are never replaced. Metals prices will rise slowly if we behave very well. If we behave less than well, which seems much more likely, then metal prices will rise more quickly. Until one day, the price pressure will insist we behave better, recycling close to 100% and raiding those rich 20th century dumps.

能源 替代能源领域的天量资本支出 能源短缺是我们各类资源问题中最容易应对的,至少理论上如此。它需要的不过是:我们的领导者拿出真正的领导力;公众具备常识;碳氢能源利益集团愿意从政治和宣传中抽身——外加一群会飞的猪!我们需要建设一个规模极大、极为智能的电网,覆盖整个美国,有朝一日或许还能延伸至加拿大。除了诸多功能之外,它还需要能够接入智能家居,在必要时将冰箱等设备暂停运行几分钟。事实上,这一切技术已属业界前沿,而在它建设所需的 10 到 20 年期间,技术和工程水平无疑会因规模巨大而大幅提升,从而进一步拉低成本。在电网背后,我们还需要在储能技术和各类可再生能源上投入真正海量的资金,尤其是太阳能和风能。过去三年,太阳能成本已出人意料地暴跌,降幅超过三分之二,最终在当今理想条件下(即便不考虑煤炭承担其全部环境成本),太阳能已具备竞争力。作为摩尔定律的一个令人欣喜的变体,太阳能成本——其下降动力既来自规模效应和工程进步,也来自新技术——将继续快速走低。(尽管从阳光中能提取的能量当然存在物理上限,而这里的好消息/坏消息是,我们大约 30 年后就会接近这个上限,但价格下降却没有这样的上限。)风能成本也会下降,虽然速度远不及太阳能,而且在非常理想的条件下也已具备竞争力。与之相反,各类碳氢能源的成本将必然地、尽管会起伏不定地持续上升。即使以应急模式(你可以称之为“曼哈顿计划之子”,但以其占当前 GDP 的比例来衡量,实际比那项非凡努力更便宜)来执行这样一个计划,也需要 20 到 30 年时间;但远在那之前,随着廉价碳氢能源逐渐枯竭,这套新系统的运营和维护边际成本就会超过我们当前系统不断上升的成本。到 2050 年,廉价碳氢能源将成为遥远的记忆。到那时,完全依赖碳氢能源的电网,在经历了绝望挣扎和限电之后,很可能会彻底瘫痪,而依赖这种电网的经济体将承受极为严峻的压力。如果我对某些国家的这一判断有误,只需在时间线上加上 10 到 20 年即可。

Energy Massive capital spending for alternatives Energy shortages are the easiest to handle of our resource problems. At least on paper. All it takes is real leadership from our leaders; common sense from the general public; a willingness of hydrocarbon interests to back off from politics and propaganda and a herd of flying pigs! We need to build a very large, very smart grid, covering the whole of the U.S. and one day perhaps including Canada. Among many tricks, it needs to be able to reach into smart homes and turn off the refrigerators and so on for a few minutes when needed. It is, in fact, all state–of-the-art already and in the 10 or 20 years it would take to build, the technology and engineering would no doubt greatly improve, given the great scale, helping to drive down the cost. Behind the grid we would need a truly massive investment in storage technologies and all renewables, especially solar and wind power. Solar costs have unexpectedly crashed in the last three years, down by over two-thirds, and finally today, in ideal conditions (even without coal carrying its full environmental costs), solar is competitive. In a happy variant of Moore’s Law, solar costs, driven by scale and engineering as much as new technology, will continue rapidly downwards. (Although there is of course a physical limit to how much energy can be extracted from sunlight and the good/bad news here is that we should be close to it in 30 years or so, there is no such limit on price reductions.) Wind power costs will also fall, if substantially less fast, and it too is already competitive in very good conditions. In contrast, the costs of hydrocarbon energy of all kinds will implacably, if erratically, rise. To carry out such a program even in crash mode (son of Manhattan project, if you will, but actually cheaper as a percentage of our current GDP than that remarkable effort) would take 20 or 30 years, but long before then the marginal costs of operating and maintaining such a system would cross the rising costs of our current system as cheap hydrocarbons steadily disappear. By 2050, cheap hydrocarbon sources will be a distant memory. Electric grids based solely on hydrocarbons would by then, after desperate struggles and brownouts, likely have turned totally black and economies based on such grids would be under very severe stress. If I’m wrong in this assertion for some countries, simply add 10 or 20 years onto the timeframe.

美国在资源问题上和许多其他方面一样,相对而言在能源方面得天独厚。新钻井技术带来的新增天然气储量和额外石油产量,将使这个国家独一无二地改善其能源状况。其中的隐患在于,这也会滋生自满情绪。在这方面,一如往常,那些“丰裕论者”会鼓励我们,告诉我们永远不必担心耗尽汽油或其他任何东西。不难想象,这会让我们坚守在消耗性碳氢化合物上,而德国以及其他国家——可能还包括 GMO 12 季度信函——《欢迎来到反乌托邦!》——2012 年 7 月——中国——则在可再生能源领域大步向前,直到它们主导这些相对劳动密集型的新产业,并最终实现极低的边际成本。随着可再生能源价格下降、碳氢化合物价格上涨,它们的优势将稳步扩大。不过,凭借新的水力压裂技术储备,未来几年能拥有一些非常廉价的能源确实令人兴奋,并且无疑会在几年内每年拉动美国 GDP 增长 0.25% 到 0.5%。但从长远来看,仅仅因为奇特的特许权使用费安排,就把天然气这种优质、不可替代的燃料定在过低的价格,是荒谬的。然而,所有这些额外储备的主要不利之处在于,它们会给我们更多的绳索,让我们有机会用其“勒死自己”——通过炙烤地球。(康奈尔大学近期的初步估计——我希望这些数据有误——认为从钻探到炉灶燃烧器,近 8% 的压裂天然气会泄漏。只要泄漏率超过 4%——可能低至 3%——天然气对全球变暖的危害就比煤炭更大。甲烷——也就是天然气的主要成分——其温室效应是二氧化碳的 20 到 100 倍。根据时间范围不同,在短期内其危害程度最高可达 100 倍,在大约 100 年的时间里则会下降到 20 到 1 倍。与其他环保人士不同,我对水力压裂的其他几种负面影响不那么担忧:烤焦地球这件事让我觉得其他负面影响相对微不足道了。)

The U.S., as in so many aspects of the resource problem, is relatively blessed in energy resources. The new reserves of natural gas and extra oil from new drilling technology will uniquely allow this country to improve its energy position. The worm in the apple is that it will also allow for complacency. In this we will be encouraged as always by the Cornucopians, telling us we will never need to worry about running out of gas or anything else. It is easy to imagine that this would leave us sticking loyally to depleting hydrocarbons while Germany and others, possibly including GMO 12 Quarterly Letter – Welcome to Dystopia! – July 2012 China, forge ahead with renewables until they dominate these new, relatively job-intensive industries and eventually end up with much lower marginal costs. Their advantage would steadily increase as renewables fall in price and those for hydrocarbons rise. Still, with the new fracking reserves it will be exciting for a few years to have some very cheap energy, and it will surely stimulate the U.S. economy in the range of 0.25 to 0.50% a year of GDP for several years. In the longer run, though, it is ridiculous to underprice natural gas, a premium, irreplaceable fuel, just because of odd royalty arrangements. The major disadvantage of all of these extra reserves, though, is that they will give us more rope with which to hang ourselves by frying the planet. (Recent estimates by Cornell University,5 which are preliminary and therefore, I hope, mis-measured, estimate that almost 8% of fracking gas leaks from drill to stove burner. Anything more than 4% (and it may be as little as 3%) makes natural gas even more dangerous to a warming planet than coal. Methane (which is what natural gas is) is 20 to 100 times worse than CO2 in its greenhouse effect. Depending on the time horizon, it is up to 100 times worse in the very near term, declining to 20 to 1 times worse over 100 years or so. Unlike other environmentalists, I worry less about other of the several negative effects of fracking: boiling the planet makes other negatives seem to me relatively inconsequential.

中国在能源领域的独特机遇——这里谈一下中国的话题。中国在认真对待未来资源可获性这一议题上,堪称独树一帜。它有悠久的儒家传统,善于以极长远的眼光思考问题,其政治家无需像我们的政客那样为连任、选民和资助者操心。同时,中国在资源问题上也展现出某种程度全然合理的恐慌,这体现在其在海外大规模购置农业用地,以及收购国外矿产资源的意愿上。我的同事们担忧中国储蓄和投资过多——大约占其所有收入的 50%,这一比例史无前例。如此之高的原因之一是,他们试图刺激经济时,特别是在全球金融危机之后,发现基于大型基础设施的公共支出最具可扩展性和可管理性。我的同事们还担心中国的资本效率低下:太多的公路、高铁线路和完全不必要的地区机场,太多的空置中产阶级公寓,甚至空置的城市。(不过依我看来,这仍比用公共资金去救助银行体系的错误,甚至保护奖金要强!但我跑题了。)然而,对于建设完全可再生的能源体系而言,这真是多么得天独厚的基础!如果中国人认为必须维持 50% 的资本支出比例(或至少平稳下降以避免彻底萧条),那么能吸收如此巨额资金,且在社会层面长期有良好投资回报的大型项目并不多。建设可再生能源体系实现了这两个目标。作为先行者,他们很快就能减少燃煤电厂的数量,并最终彻底淘汰。30 到 40 年内,他们可以逐步关闭最后一批燃煤电厂,停止缓慢毒害城市居民,同时帮助停止缓慢炙烤地球。(不过,或许最后一批燃煤电厂可以保留碳捕集与再利用模式——他们目前在世界上首次进行半大规模试验的正是该领域——因为这类电厂能提供部分基础负荷以平抑风能和太阳能的不稳定性,从而使负荷平衡变得容易得多。)

China’s unique opportunity in energy Time out here to take a look at China on this point. China has been in a class of its own in taking seriously this topic of future availability of resources. It has a long Confucian tradition of thinking very long term and its politicians do not have to worry about being re-elected or about voters and funders as much as ours do. It has also shown a degree of entirely justifiable panic on this resource issue as reflected in massive agricultural land deals outside of China and in a willingness to acquire foreign-based mineral resources. My colleagues worry that the Chinese save and invest too much, approximately half of all their income, a level never before reached in history. One of the reasons for so high a level is that in their attempts to stimulate their economy, notably after the global financial crisis, they found giant infrastructure-based public spending to be the most scalable and manageable. My colleagues also worry about the capital inefficiency in China: too many roads and fast rail lines and completely unnecessary regional airports and too many empty middle class apartments and even empty cities. (For my money, though, this still compares favorably to using public funds to bail out the banking system’s errors and even protecting bonuses! But, I digress.) But for undertaking a completely renewable energy system, what a set-up! If the Chinese feel they must maintain a 50% capital spending ratio (or at least come down gracefully to avoid an outright depression), there are few projects big enough to both absorb the giant quantities of money available and have a good return on investment at the societal level in the long term. Building a renewable energy system achieves both aims. As a first mover they would quickly be able to build fewer coal utilities and, eventually, none. In 30 or 40 years they could phase out the last of them and stop slowly poisoning their urban residents while at the same time helping to stop slowly cooking the Earth. (Perhaps, though, the last coal plants could be kept in carbon capture and recycling mode – in which field they are undertaking today the first semi large-scale test in the world – for such plants would make load balancing that much easier by providing some base load to smooth out the variability of wind and solar.)

中国人已经在风能和太阳能的建设与研究领域崭露头角,成为领先者。如果规模进一步扩大,他们的成本优势将难以匹敌;一旦可再生能源体系建成,他们最担心的问题——能源安全——也将随之消失。比较一下他们的问题——“我们怎么花掉所有的钱?”——和我们自己的问题——“我们怎么还清所有的债?”——你就会明白我们的障碍高出了多少。相比之下,我们需要更英勇的领导力,以及大量那些“会飞的猪”。与此同时,中国的大规模努力既是很好的榜样,也是一种商业激励,促使其他国家跟进。加油,中国!

The Chinese are already becoming leaders in wind and solar power construction and research. At much higher scale, their cost advantages would be hard to match, and if a renewable energy system were to be completed, their biggest long-term worry of all – energy security – would be gone. Compare their problem – “How do we spend all of our money?” – with ours – “How do we pay back all of our debts?” – and you can see why our hurdles are so much higher. It will, in comparison, need much more heroic leadership from us and plenty of those flying pigs. In the meantime, a major Chinese effort would be both a great example and a commercial goad to encourage others to follow. Go China!

对研究的必要性 随着太阳能和风能的可再生项目推进,应同时为其他有前景的可再生能源提供研究支持和财务激励。这包括将藻类及其他植物物质转化为液态燃料,或许还需要研究基于钍的核能,甚至可能包括核聚变——尽管这些技术(最终失败)的风险很高,但其回报也同样巨大——近乎无限的增量能源供应。(这很可能值得投入资金。)

The need for research As renewable projects for solar and wind go forward they should be accompanied by research and financial encouragement for other promising renewables. This would include converting algae and other vegetal matter into liquid fuels, perhaps research into Thorium-based nuclear, and possibly even fusion, for which the risks (of eventual failure) are high, but so are the returns – almost infinite supplies of incremental energy. (It is probably worth 5 Professor Robert Howarth, “Climate Change Letters” (105:5), May 2012.

GMO 13 季度信函——欢迎来到反乌托邦!——2012 年 7 月,这里要提一下,根据热力学第二定律,你不可能无限地给地球升温。所有热量都必须通过红外辐射散发出去。这就是为什么城市比乡村温度更高的原因,因为城市有更多废热。如果能源年增长率为 2.3%,持续 400 年,即便全部来自可再生能源或核聚变(这能排除温室效应的考量),地球温度也会达到沸点,届时只剩少数最近才发现的生物能存活。在这个仍然燃烧碳氢化合物、事实而非观点说了算的世界里——虽然有时你根本看不出来——未来 100 年温室效应的强度很可能是热力学效应的 300 倍。但或许最需要研究的是电力存储,这将远成为理想可再生能源体系中最薄弱的经济环节。几乎每周都有新发明的、巧妙的方法公布,但它们似乎总是近在眼前。在这个领域,我们或许该用上那些永远乐观派常挂在嘴边的“人脑的无限能力”;而这一次,连我这个快乐现实主义者(这可不是件容易的事!)也相信,最终确实会出现某种真正的突破,至少是在成本层面,如果不是在高端科学层面的话。这肯定会有帮助。

GMO 13 Quarterly Letter – Welcome to Dystopia! – July 2012 mentioning here that, courtesy of the second law of thermodynamics, you cannot indefinitely heat up the world. All heat must be dissipated through infrared radiation. This is why cities with more waste heat are warmer than the countryside. Given energy growth of just 2.3% a year, for 400 years, even if the supply is 100% renewable or fusion [to remove the need to consider the greenhouse effect], the planet’s temperature would reach boiling point and only a few recently discovered organisms would be left. In this world, where hydrocarbons are still burned and where facts rather than opinions hold – although sometimes you would never know – the greenhouse effect in the next 100 years is likely to be 300 times the thermodynamic effect.) But perhaps the greatest need for research is in power storage, which will become by far the weakest economic link in the desired renewable energy system. There are almost weekly announcements of new, ingenious approaches, but they seem always to be just around the corner. This would be a good area to have some of that “infinite capacity of the human brain” one hears so much about from the perma-optimists, and for once even I, a cheerful realist (which is no mean feat!), believe there will indeed be, eventually, some real breakthrough, at least in cost if not heavy science. It would certainly be helpful.

如今必须严肃应对了。在前几篇文章中,我试图说明人口或实体产出保持任何永续稳定增长都是完全不可能的事:我曾经指出,1% 的复利增长持续 3000 年,人口或财产将变成最初数量的 7 万亿倍。但对于那些着眼较短时间的人来说,正如我们所看到的,热力学效应本身已设下一个完全独立的天花板:即使每年仅以 2.3% 的温和速率增长,能源使用的增长也只能持续区区 400 年。若加上气候变化的影响,按照目前的趋势,用不了 400 年,人类就会完蛋。在一个有限的星球上,我们根本不可能实现指数级增长,但几乎没有政治家(这可以理解),也几乎没有经济学家(这几乎令人难以置信)愿意处理这个话题。我们在面对资源短缺——尤其是转向可再生能源的必要性——方面拖延得越久,问题就变得越严重。例如,等到碳氢化合物价格达到“临界点”时,一些国家可能已经没有能力——政治、社会或经济上的能力——来满足所需的巨额投资,它们将或多或少地永远陷入困境。在 20 世纪 30 年代末,丘吉尔面对政界和公众对令人不快的消息——德国重整军备及其敌对意图——所表现出的顽固不化、拒不面对的态度。最终,当问题即便对最迟钝的人也显而易见时,他忍不住说了句“我早就告诉过你们”。他说:“拖延、半心半意、一再推迟的时代即将结束……取而代之的是,我们正在进入一个承担后果的时代。”这次,我们已然看到了早期的后果,但我们仍在拖延。

The need for a serious effort now In earlier pieces I tried to convey the sheer impossibility of any perpetual rate of steady growth in people or physical output: 1% compounded for 3000 years, I noted, would multiply people or possessions by seven trillion times the original number. But for those with shorter horizons, the thermodynamic effect on its own, as we’ve seen, puts a quite separate ceiling of a mere 400 years’ growth in energy use at a modest 2.3% growth a year. Throw in climate change effects and our species would be toast long before 400 years would pass if present trends continue. We simply cannot have exponential growth on a finite planet, but no politicians (understandably) and almost no economists (almost unbelievably) will deal with this topic. The longer we delay in facing up to resource shortage, especially the need to go to renewables, the more severe the problem becomes. For example, by the time hydrocarbon prices go “critical,” some countries may not have the capability – political, social, or economic – to meet the substantial investments required and they will be left more or less permanently floundering behind. In the late 1930s, Churchill faced intractable unwillingness to deal with unpleasant news – German rearmament and hostile intentions – on the part of both politicians and the general public. Finally, as the problem became obvious even to the most block-headed, he could not resist a little “I told you so.” He said, “The era of procrastination, of half measures … of delays is coming to its close … In its place we are entering a period of consequences.” This time we can already see the early consequences but we still delay.

但我们仍在拖延……拖延甚至否认的原因多种多样。在美国,一些政客可以理解地拼命保护本州的就业岗位——至少在短期内如此。作为回报,他们中有人从碳氢化合物利益集团那里获得帮助以争取连任。这些碳氢化合物公司反过来保护它们庞大的现有和地下未来储量价值,这些储量往往代表了它们的全部市值。它们大概还认为自己是在为股东的利益行事,而这种利益被时下流行且极其狭隘地解读为中期利润最大化。其他潜在的利害相关方,包括所属国家及其当下与未来公民的福祉,通常根本不被考虑。一些拖延者是自由意志主义者,他们就是讨厌政府干预,无论事实或情况如何。但数量多得多的,是那些衷心希望一切都能顺利解决、期盼未来能像过去美好时光一样轻松的普通人。然而,思考和希望并不能让理想成真,而拖延和否认是危险的、甚至可能致命的游戏。

But we still delay… The reasons for delay and even denial are varied. In the U.S., some politicians are understandably desperate to protect jobs, in the short term, in their state. In return for so doing, some receive help from hydrocarbon interests in getting re-elected. They, the hydrocarbon companies, are in turn protecting the value of their huge current and future reserves in the ground, which often represent all of their market value. They also presumably feel that they are acting in their shareholders’ interest, which interest is interpreted in the currently fashionable and extremely narrow sense of maximizing intermediate-term profits. Other possible stakeholders, including the country of origin and the well-being of its current and future citizens, typically play no role at all. Some delayers are libertarians who just hate government intervention regardless of the facts or circumstances. But far, far more numerous are the ordinary people who would just dearly love for everything to work out well and the future to be as easy as it used to be in the good old days. But thinking and hoping will not make it so, and delay and denial are dangerous, even potentially lethal, games to be playing.

最后,我们是谁?

Finally, who are we?

这就引出了我对粮食与资源问题的最后一点看法:我们所有的资源问题(以及就此而言,绝大多数其他问题),只要我们振作起来,动用理论上我们拥有的全部能力,都是可以解决的。我所看到的大多数偏乐观的计算和预估,都建立在一个假设之上:我们会那样做,我们是理性经济人(就像投资领域一样)——理性、聪明、信息灵通、心怀善意且廉洁奉公。可实际情况根本不是这样。我们信息闭塞,又偏执地喜欢好消息,轻易就能回避令人不快的事实;我们的观点很容易被既得利益者操纵;我们有时效率低得可怕;而且我们显然是相当容易腐败的。正是基于人类这种普通、未开化的假设,我们的全球粮食前景——以及由此引发的未来政治不稳定——才会显得如此危险。

This brings me to my final point on our food and resource problems: all of our resource problems (and most of all of our other problems for that matter) are soluble if we rise to the occasion and use all of the abilities that, on paper, we have. Most of the more optimistic calculations and estimates that I see are based on the assumption that we will do just that, that we are homo economicus (just as in investing): rational, smart, well informed, well-intentioned, GMO 14 Quarterly Letter – Welcome to Dystopia! – July 2012 and incorruptible. Well, it just ain’t so. We are badly informed, passionately prefer good news, and easily evade unpleasant facts; our views are easily manipulated by vested interests; we are sometimes desperately inefficient; and we are apparently corruptible as heck. It is on this assumption of ordinary, unenlightened humans that our global food outlook and, in consequence, our future political instability, looks so dangerous.

不过,偶尔我们也能真正挺身而出。上一次是在二战期间,特别是曼哈顿计划那会儿。当然,那时的美国社会团结得多,国会也更愿妥协。我们还有一个清晰而直接的敌人——它通过一次偷袭(对我们来说堪称绝妙)把全国凝聚起来。但总而言之,那是多么了不起的努力,也是对今天那些认为政府从来办不成任何事的人的有力回击。如果那真是事实,战争就会输掉,世界也会变成完全不同的模样。不过,今天的威胁更偏技术性,进程缓慢得多,敌人似乎也面目模糊。另一方面,如果我们不尽快集体行动,这次付出的代价将更为惨重,波及整个地球。是时候再来一次“蓝月亮”了。加油吧,世界!

But once in a blue moon we really do rise to the occasion. The last time was World War II in general and The Manhattan Project in particular. Of course, we were a much more cohesive society then and we had a Congress much more willing to compromise. We also had a clear and immediate enemy who brilliantly (for us) galvanized and united the country by a sneak attack. But, all in all, what a magnificent effort and what a rebuttal to those today who think no government can ever do anything right. If that were indeed true, the war would have been lost and the world would have become a very different place. The threat today, though, is more technical and very much slower burning and the enemy seems amorphous. On the other hand, the penalties this time will be even greater and for the whole planet if we collectively do not start to act soon. It is time for another blue moon. Go world!

资源限制的最新投资启示。一句话总结就是:我对人类面临的问题深感悲观,而可悲的是,对资源却极为乐观。毫不意外,与一年前相比,我更加确信资源价格上涨(以及由此带来的社会和国际动荡)是不可避免的。因此,我对一年前提出的投资作战方案也更有信心。对于任何有十年或更长投资视野的负责任投资团体而言,都应稳步将资源相关投资作为主要配置。就我的基金会而言(即个人层面,而非机构层面——在机构层面,我们显然无法强求客户接受十年以上的投资周期),我设定的最终目标是 30% 配置于资源类资产,目前正缓慢分批买入,尽管担心短期价格大幅下跌,但更担心完全错过我自己的判断。在我的基金会中,目前已完成该目标约三分之二,配置比例为 20%。

Updated Investment Implications of Resource Limitations The one-line summary is this: I am very bearish on the problems we humans face and, sadly, very bullish on resources. Not surprising, I am even more convinced than I was a year ago of the inevitability of rising resource prices (and, unfortunately, associated societal and international instability). Therefore I am more confident in my suggested investment battle plan of a year ago. For any responsible investment group with a 10-year horizon or longer, one should move steadily to adopt a major holding of resource-related investments. For my Foundation (i.e., personally as opposed to institutionally where, reasonably enough, we cannot impose 10-year plus horizons on our clients) I had adopted 30% in resources as my eventual target and was slowly averaging in, nervous of near-term substantial price declines, but even more nervous of completely missing my own point. In my Foundation, I have currently reached about the two-thirds point of 20%.

我个人比较主观地,把一个 30% 的目标配置拆解如下:林业与农田占 15%,“地下的东西”占 10%,资源效率类投资占 5%。随着我对其中某些子类更加熟悉,或者看到异乎寻常的机会,我会调整这个比例。不过就长期而言,我确实视农田和林业为优先级更高或者说更偏好的配置:矿业和石油公司从价格上涨中获益丰厚,但作为资本主义企业,它们每年都需要不断补充可售存货,而这会慢慢变得完全不可能做到。农田则不同:它们同样受益于大宗商品价格上涨,但它们的“地下的东西”就是土壤,如果管理得当,土壤每年都能完全再生其生长能力,甚至还带有温和上升的趋势。不过,在潜在的“地下的东西”这个子组合里,有一个类别我会避开:煤炭和油砂。这主要不是因为它们对环境造成的惊人代价让我良心不安;而是因为,在我看来,随着气候损害日益明显,这些能源的使用受到限制的可能性会稳步增大。

My personal, somewhat arbitrary breakdown of a targeted 30% is to have 15% in forestry and farms, 10% in “stuff in the ground,” and 5% in resource efficiency plays. I will change the mix as I become more comfortable with some of the subsets or as I see exceptional opportunities. I do, though, see farms and forestry as the senior or preferred component, if you will, for the longer term: mining and oil companies benefit a lot from rising prices, but they suffer from the need, as capitalist enterprises, to keep replacing their stock in trade every year and this slowly becomes impossible to do completely. Farms, however, also benefit from rising commodity prices but for them their “stuff in the ground” is soil, which, if well managed, has fully renewed growing capacity each year, usually even with a modestly rising trend. There is one component of the potential “stuff in the ground” sub portfolio, though, to which I would give a miss: coal and tar sands. This is not primarily because their incredible cost to the environment hurts my conscience; it is because, in my opinion, the odds will steadily grow as climate damage becomes increasingly apparent, that their use will be curtailed.

在离开这个话题之前,我想提供一个小信息,是关于地上实物真实价格上涨与持有这些储量的公司相对优异表现之间的强相关性。想象一下在附件 2 中我正用 PowerPoint 逐页展示:点击第一页“A”,你会看到 2002 年之前原材料价格的持续下跌。点击第二页“B”,你会看到在此前环境下矿业股随之出现的持续、非常长期的落后表现:每一年它们都在对存货进行减记,每一年其主要资产的价值都在缩水——一个很难繁荣的环境。点击第三页“C”,你会看到 2002 年以后资源价格的急剧突破,最后点击“D”,你会看到矿业股同样戏剧性的优异表现。这种相关性高达惊人的 0.52。对其他资源来说,相关性通常更低——大约 0.3 左右。这是因为原材料价格上涨对一家多元化公司的不同部分可能既有利也有弊。例如,大型石油公司既是石油的卖家,也是其资本密集型炼油厂的买家,这削弱了与油价变化的直接关系。但总体而言,我认为你可以有把握地预期:如果资源价格在实值上持续上涨,那么资源股就应该跑赢市场。

Before I leave this topic I would like to throw in a tidbit concerning the strong relationship between real price increases in stuff in the ground and the relative outperformance of those companies that own the reserves. Imagine in Exhibit 2 that I am clicking through on PowerPoint: Click one “A” would show the steady decline in raw material prices to 2002. Click two “B” would show the accompanying steady, very long-term underperformance of mining stocks in that previous environment: every year they took inventory markdowns and every year the value of their main asset lost value, a tough environment in which to prosper. Click three “C” would show the dramatic breakout of resource prices after 2002, and the final click “D” would show the equally dramatic outperformance of the miners. This relationship is a remarkable .52. For other resources it is typically lower – around .3. This is because raw material price rises can help and hurt different parts of a diversified company. Large oil companies, for example, are both sellers of oil and buyers in their capital-intensive refineries, which mutes the direct relationship with oil price changes. In general, though, I think you can confidently expect that if resource prices steadily rise in real terms, then resource stocks should outperform the market.

去年我曾警告,我认为资源价格下跌的可能性很大。我指出,恶劣天气——2010 年或许是 150 年一遇的全球性事件——肯定会有所好转,而中国看起来可能步履蹒跚,或至少会放缓增长。此外,价格从 2009 年的低点快速大幅回升,也吸引了一些纯粹的趋势投机。自那以后,我逐渐相信,矿商在完成产能和基础设施扩建方面可能有意“放慢脚步”——价格如此之高,谁又能责怪他们呢?——或许还存在一些真正的寡头垄断、类似卡特尔的行为,大概属于合法的那种,目的是维持价格高位。然而,在根本层面(请原谅我用了这个词),数据让我们可以确信,主要的输入因素是一场范式转变,或者说相变,由当前和潜在需求与长期潜在供给之间深刻失衡所引发:也就是说,我们确实在快速耗尽廉价资源。但如今,额外的金属产量终于开始投产,以美国为主的新页岩气与石油生产(以及储量)的繁荣仍在继续。在需求端,全球经济增长,尤其是中国和欧洲,正在放缓。结果,大多数“地下资源”的价格已从峰值下跌约 25% 至 35%,而随着天气好转,截至 6 月初,农产品的平均跌幅也大致相当。

The bad weather – perhaps a 1-in-150-year global event in 2010 – would surely get less bad, I argued, and China looked likely to stumble or at least slow down. Some outright momentum speculation had also been attracted by the rapid and large price recoveries from the lows of 2009. I have been persuaded since then that there was likely some deliberate “go slow” on the part of miners to complete capacity and infrastructure extensions – with the prices so high, who could blame them? – and perhaps some genuine oligopolistic, cartel-like behavior, probably of a just legal variety to keep prices up. Yet at bedrock (pardon the expression) the data allowed for certainty that the main input was a paradigm shift, or phase change, caused by a profound shift in balance between current and potential demand and long-term potential supply: i.e., we are indeed rapidly running out of cheap resources. Today, though, extra metal production is finally coming on line and the boom in new fracking gas and oil production (and reserves) mainly in the U.S. continues. On the demand side, global economic growth, especially in China and Europe, is slowing. As a result prices have fallen by about 25% to 35% from their peaks for most “stuff in the ground” and, with the weather less bad, have also fallen by a similar average amount for agricultural products up to the beginning of June.

气候问题突然闯入。嗯,在农业领域,一个月的时间可不短,尤其是近些年的情况。六月初开始,全球又出现一轮反常天气。今年问题的中心与去年如出一辙:美国中西部,加上北半球小麦种植带的干旱天气。受到严重干旱和 90 到 100 华氏度酷热高温的侵袭,全球最大的美国玉米作物受损,价格在一个月内惊人地飙升了 50%。大豆也遭遇了类似情况。几乎一夜之间,三种最重要农作物中的两种就回到了 2008 年的高位——当时人们常形容那是“再也见不到了”的价格。小麦价格同样逼近 2008 年高点,并且在过去六周内上涨了超过 40%。

Climate problems intrude Well, a month is a long time in agriculture, particularly these days apparently. For starting in early June there came yet another burst of anomalous global weather. The center of this season’s problem is as it was last year: the U.S. Midwest coupled with dry weather around the Northern Hemisphere’s wheat belt. Suffering intense drought and 90-to 100-degree searing heat, the U.S. corn crop, the world’s largest, has been damaged and the price has jumped an astonishing 50% in a month. A similar story exists for soy beans. In almost no time, two of the three most important crops have gone back to the highs of 2008, which were often described as “never to be seen again.” Wheat also is within striking distance of its 2008 high and up over 40% in the last six weeks.

我们来谈谈这意味着什么。这与 2008 年完全不同,当时农作物种植量并未特别庞大。然而,自 2008 年价格大幅上涨以及 2011 年从崩盘影响中意外反弹以来,前所未有的总种植面积被投入生产,以利用高得多的价格。2008 年还有一个强有力的理由,即价格在一年内翻倍吸引了前所未有的投机动能因素。但这一次,尽管种植规模巨大,纯粹恶劣的天气却让市场措手不及。至于投机,仅仅六周前,投机者还在做空谷物!全球需求现在如此之高且增长如此之快,而储备又如此有限,导致系统内的缓冲似乎完全消失,面对像今年这样的恶劣天气,脆弱性已大幅增加。

Let’s discuss what this means. It is not at all like 2008, when the planted crops were not that exceptionally large. However, since the massive rise of price in 2008 and the unexpected rebound in 2011 from the effects of the crash, unprecedented total acreage has been planted to take advantage of the much higher prices. There was also a strong GMO 16 Quarterly Letter – Welcome to Dystopia! – July 2012 case back in 2008 that there was an unprecedented speculative momentum element attracted by prices doubling in a single year. This time, though, just plain awful bad weather blindsided the market despite the massive planting. And as for speculation, just a brief six weeks ago speculators were short grains! World demand is now just so high and growing so fast and reserves so modest that the slack in the system appears to have completely gone and vulnerability to bad weather like this year’s has increased enormously.

再来谈谈天气,因为它确实开始产生可能会付出昂贵代价的投资影响了。全球范围内,2010 年在我看来像是 150 年一遇的事件——俄罗斯等地遭遇极端高温,巴基斯坦和澳大利亚则经历了圣经般的大洪水。这严重打击了全球粮食产量。我当时曾想,接下来的季节至少应该没那么糟了吧,可结果呢?泰国——全球最大大米出口国——全国一半地区洪水齐腰深,密西西比河遭遇 80 年一遇洪水,得克萨斯州高温远超此前纪录,而许多其他地方则遭受了相当严重的干旱。全球来看,这或许算是 50 年一遇的事件。所以,归根结底,也许我没错;它确实“没那么糟”,但远不是我原意所指的那样。而现在,就在我思考这封信时,突然之间,50 年一遇的干旱和高温又袭击了我们的主要种植区。那么,我们就暂且称之为全球 20 年一遇吧,因为巴西、阿根廷、俄罗斯以及其他几个地区也出现了异常恶劣的天气。任何统计学家在看到 150 年一遇、50 年一遇、20 年一遇连续出现时,都会开始感到不安。长期天气记录并不完善,这很大程度上是判断性的,但连续这三年的情况,我们只能说,极为反常。(美国国家海洋和大气管理局表示,今年中西部地区的热浪不受气候变化影响的概率不到百万分之一。其他来源则使用了更低得多的概率,比如十万分之一。我姑且称之为“极为反常”吧。)我们确实必须开始将恶劣且多变的种植天气概率上升这一因素纳入投资方程。

And let’s talk about the weather, for it is indeed beginning to have investment implications that might be expensive to ignore. Globally, 2010 looked to me like a 1-in-150-year event with heroic heat in Russia and elsewhere and biblical floods in Pakistan and Australia. It really hurt global grain output. I suggested then that surely the following season had to be at least less bad, and what did we get? Thailand, the largest rice exporter was knee-deep in floods over half the country, 80-year floods occurred in the Mississippi, Texas sweltered in way-above record heat, and quite severe droughts gripped many other places. Perhaps in total a 1-in-50-year event globally. So, after all, perhaps I was right; it was “less bad” but hardly what I meant. And now, quite suddenly, even while I was thinking about this letter, 1-in-50-year drought and heat have hit our major growing areas. So let’s call this a 1-in-20-year globally, for Brazil, Argentina, Russia, and several other areas are also having unusually bad weather. Any statistician starts to get jumpy when looking at 1-in-150, 1-in-50, and 1-in-20 back to back. Long-term weather records are poor and a lot of this is judgmental, but this three-year stretch is, shall we say, very unusual. (The National Oceanic and Atmospheric Administration has said that the chance that this year’s heat in the Midwest was not affected by a warming climate was over 1 in 1 million. Other sources have used much punier odds, such as 1 in 100,000. I will settle for “very unusual.”) We really have to start factoring into the investment equation increased odds of difficult and volatile growing weather.

潜在价格下跌与遗憾最小化 再回到投资组合,矿业和石油公司可能还有大约 20% 的相对表现不佳风险(随着美国新油气供应持续扩大),加上中国已从一年前的“可能放缓”变为明确减速,而欧元问题与美国财政悬崖足以让久经沙场的冷静投资老手也感到不安。(下行结果有个令人不安的习惯:往往是你预估的两倍。)谷物价格再度反弹后十分脆弱,土地价格通常需要连续两三年歉收才会受到传导影响。因此,农场价格始终居高不下,这对潜在买家而言既令人沮丧又充满危险。农场买家被迫放眼全球——尽管我建议只考虑安全友好的国家——去搜寻折价交易和特殊机会。不过幸运的是,农场市场效率极低,总能在某个地方找到相对便宜的机会。

Possible price declines and regret minimizing Moving back to the portfolio, there is probably a risk of another 20% or so relative underperformance in the miners and oil companies (as the new supplies of U.S. oil and gas continue to expand) and as China has gone from our “likely to slow” a year ago to definitely slowing, and the euro and fiscal cliff in the U.S. are enough to make even seasoned cool-cat investors jumpy. (And downside results have a disturbing habit of being twice what you counted on.) Grain prices, having bounced once again, are very vulnerable and land prices typically need a couple of bad grain years in a row to have the effect pass through to them. So farm prices have stayed resolutely high, which for potential buyers is both frustrating and dangerous. Farm buyers are forced to look globally – although I advise safe and friendly countries only – and hunt for bargains and special cases. Fortunately, though, farms form a very inefficient market and there are always relative bargains to be had somewhere.

资源问题很可能会挤压投资组合中其他部分的收益。因此,我那个关于最小化后悔的建议仍然有效:根据事态发展,在未来一、两或三年内缓慢分批建仓。但景象中一个重要因素已经变了。不仅我比一年前更加确信,理性长期投资者的 7 至 10 年视角应该超配资源(30% 大约是市场权重的两倍),而且我现在也确信,资源价格上涨将通过挤压利润率并降低整体增长,从而恶化投资组合中剩余部分的前景。

Resource problems are likely to squeeze the balance of the portfolio So my regret-minimizing advice still holds: average slowly in over the next one, two, or three years depending on developments. But something important in the picture has changed. Not only am I more convinced than a year ago that sensible long-term investors’ 7- to 10-year horizons should overweight resources (30% is about two times market weight), but I am now also convinced that rising resource prices will worsen the prospects for the balance of the portfolio, by both squeezing profit margins and reducing overall growth.

如果判断正确,这将对捐赠基金和养老基金的长期回报产生严重影响:在其他因素不变的情况下,长期国内生产总值低速增长可能意味着所有资本的回报都将走低。这个问题,连同对整体 GDP 增长的讨论、以及我为何认为未来 GDP 增速很可能低于普遍预期的分析,将在下个季度展开讨论。与此同时,值得思考的是:哪类公司更能抵御较低 GDP 增长的影响——尤其是在发达经济体——并且更有能力吸收资源价格上涨带来的压力?答案依然是:我们偏好“优质”股票。它们的资源成本占营收比例远低于典型公司,而且拥有更高的利润基础来抵御利润率压力。

If correct, this will have serious implications for longer-term endowment and pension fund returns: among other factors, a lower growth for GDP in the long term may mean lower returns on all capital. That question, along with a discussion of overall GDP growth and why I think it is likely to be lower in the future than generally expected, will be discussed next quarter. In the meantime, it may be worth asking which kind of company will better resist lower GDP growth, especially in the developed world, and be better able to absorb pressure from higher resource prices. Once again, we prefer “quality” stocks. They have much lower resource costs as a percentage of total revenues than typical companies and they have a higher margin base from which to resist margin pressure.

GMO 第 17 期季报 – 欢迎来到反乌托邦!– 2012 年 7 月 “土拨鼠之日” 经济环境似乎陷入一种相当令人不快的永久循环。希腊总在违约边缘;最新一轮纾困计划总说能解围,却似乎从未真正奏效;中国总被认为即将崩溃,却只是缓慢下行来撩拨我们;我发誓《金融时报》已经开始重复使用旧报道了!在美国,财政悬崖隐约逼近,债务上限和惯常的选举不确定性也一并袭来。功能失调的美国国会目前依然固执己见、难以妥协。股市涨了又跌,跌了又涨。要在客户会议上找到什么新话题来讲,越来越难了。就我个人而言,我真希望这世界赶紧迎来下一步会发生的事。不过,有个小小的变化是,那些高得惊人(几乎令人难以置信)的利润率与盈利增长,终于有所减弱了。这些因素,连同伯南克的超低利率,一直是市场的两大支柱,而且这两个支柱还不算差:在这样一个极度令人不安的金融与经济世界里,我们年内居然涨了 8%。随着利润率减弱,其中一根支柱摇摇欲坠,股价下跌的可能性似乎比以往更大了。

GMO 17 Quarterly Letter – Welcome to Dystopia! – July 2012 “Groundhog Day” The economic environment seems to be stuck in a rather unpleasant perpetual loop. Greece is always about to default; the latest bailout is always about to save the day and yet never seems to; China is always about to collapse but instead teases us by inching down; and I swear the Financial Times is beginning to recycle its reports! In the U.S., the fiscal cliff looms along with debt limits and the usual election uncertainties. The dysfunctional U.S. Congress continues for the time being in its intractable ways. The stock market rises and falls and rises and falls again. It is getting difficult to find anything new to say at client meetings. I, for one, wish that the world would get on with whatever is coming next. One slight change, though, is that fantastic (almost unbelievable) profit margin and earnings gains have finally weakened a little. They, together with Bernanke’s super low rates, have been the twin pillars of the market and not bad ones at all: here we are up 8% for the year in a thoroughly unsettling financial and economic world. With margins weakening, one of the twin pillars is looking shaky and price declines look more likely than before.

GMO 第 18 期季报——欢迎来到反乌托邦!——2012 年 7 月 GMO 评论 2012 年 7 月 当坏事降临到廉价资产头上 本·英克 我们是价值投资者。我们的职责是在认为资产廉价时买入。价值投资者买入廉价资产的标准理由是,廉价资产能带来超额回报。而我们更进一步,不仅声称廉价资产平均表现更好,而且风险更低——这里的风险指的是资本永久性损失的可能性和规模。历史似乎支持我们的说法,但问题在于,我们从这一趋势中能获得多少信心?换种说法,我们得对坏事降临到廉价资产头上的可能性有多担忧?

GMO 18 Quarterly Letter – Welcome to Dystopia! – July 2012 GMO Commentary July 2012 When Bad Things Happen to Cheap Assets Ben Inker W e are value managers. We view it as our job to buy assets when we believe they are cheap. The standard reason value managers give for buying cheap is that cheap assets outperform. We’ve gone farther than merely saying that. We have claimed that cheap assets not only perform better on average but also have lower risk where risk is considered as the likelihood and size of a permanent impairment of capital. History seems to be supportive of our claim, but the question is how much comfort can we take in this tendency? Or to put it another way, how concerned do we have to be about the potential of bad things happening to cheap assets?

如果有人对高价资产可能导致资本的永久性减值曾存有丝毫怀疑,我们希望过去十余年的经历已让他们摒弃这一观念。从 2000 年 3 月到 2012 年 6 月,标普 500 指数实际下跌了 15%。但把此归因于估值过高造成的永久性资本减值,这还远远不够。那些在 2000 年 3 月投资、信奉长期持股的投资者,并非指望能在股市里熬过 12 年后收回实际成本的本金;他们期望的是每年 7% 的长期实际收益率。这个 7% 的实际数字之所以被美化,是因为市场最终的估值远高于 1900 年、1926 年、1945 年、1970 年——老实说,也包括历史上你随便挑的任何起始点。但如果我们把 5%-6% 的实际收益率视为持有股票的合理回报,那么投资者本应预期在此期间获得 85% 到 110% 的收益,这使得投资于被高估的标普 500 指数所造成的资本永久性减值,大约落在 55%-60% 的区间——这一点在图表 1 中或许更易看清。我在此把这种状态称为“永久性”,多少有些笼统,但考虑到我们认为标普 500 指数至今仍然严重高估,我愿意用一个可能性来交换:即标普 500 指数未来可能惊人地上涨,从而减轻了损失;而另一种可能性是,我们尚未完全经历这场减值。2007 年至 2009 年的损失,大体上也是高价资产遭遇不幸的案例。尽管大量资产在底部时相对于公允价值已变得便宜,但总体而言,那些至今仍受资本减值困扰的地方,正是那些资产在本轮周期开始时交易价格远高于历史估值水平的领域。我在这里说“总体而言”,是因为关于损失仅仅是高价资产回归公允价值这一观点,存在两个可能的例外。

If anyone had ever had a doubt about the potential for expensive assets to inflict a permanent impairment of capital, we hope that the experience of the last dozen years has disabused them of that notion. From March 2000 to June 2012, the S&P 500 lost 15% in real terms. But declaring that to be the permanent impairment of capital from the overvaluation is a significant understatement. Believers in stocks for the long run who invested in March 2000 were not expecting to get their money back in real terms after 12 years in the stock market; they were expecting to get the long-term average return of 7% real per year. The 7% real figure was flattered by the fact that the market had ended at a much higher valuation than it started at in 1900, or 1926, or 1945, or 1970, or quite frankly any starting point in history you wanted to pick. But if we took 5-6% real to be the fair return to owning equities, investors would have expected to earn between 85% and 110% over the period, making the permanent impairment of capital from investing in the overvalued S&P 500 somewhere in the 55-60% range, which can perhaps be more easily seen in Exhibit 1. I’m doing a bit of hand waving in declaring that to be “permanent,” but given that we believe that the S&P 500 is still substantially overvalued today, I’d trade off the possibility that the S&P 500 makes a stunning run higher that mitigates the loss against the possibility that we are not yet done with the totality of this impairment. The losses from 2007-09 were also generally a case of bad things happening to expensive assets. While plenty of assets wound up cheap relative to fair value by the bottom, by and large the places where one is still nursing impairment to capital are those places where the assets came into the period trading well above their historical valuation levels. I say “by and large” here because there are two potential exceptions to the idea that the losses were simply due to expensive assets falling back to fair value.

银行是个例外,自 2007 年市场高点以来,美国和 EAFE 市场的银行股实际价值已下跌约 60%。就资本减损而言,银行属于异类。首先,它们是高杠杆实体,资产或负债的微小变化都可能导致权益价值大幅变动。其次,它们是 2007 年大量高估资产的主要持有者,主要是公司债务和抵押贷款,这是非金融公司不会面临的问题。第三,由于杠杆的存在,当它们遭受损失时,会形成一条非常危险的反馈回路。这些损失迫使它们筹集权益资本,如果损失巨大,投资者会通过将其估值压低至账面价值以下来惩罚它们。在账面价值以下为杠杆实体进行资本重组,往往会对股东产生相当的稀释效应,而这种稀释就是永久性的资本减损。所以,如果你有一大堆高度杠杆化的实体,一旦它们在资产上遭受重大损失,就必然导致你的永久性资本减损,而且它们持有的资产又严重高估,那么可能根本不存在一个估值水平能让它们称得上“便宜”。一旦它们承受了损失,事情就另当别论了,如今金融股也可能是便宜的。就我们而言,我们仍对它们有些戒心,因为其资产负债表上还可能潜藏着什么其他风险,并不完全清楚。另一个可能的例外是欧元区股票。它们的跌幅小于银行——欧元区(剔除金融股)从其高点算起,以实际欧元计,仅下跌了 33%。截至 2007 年 10 月,我们的预测显示,EAFE(剔除日本)需要下跌 33% 才能达到公允价值。假设当时欧元区的定价与非美国其他市场类似,那就意味着,如果市场今天处于公允价值且没有资本减损,那么它本应下跌 13%(估值下跌 33%,但 4.7 年的股息和实际销售增长现在本该已经减轻了跌幅)。那么,欧元区是便宜了,还是遭受了某种永久性的资本减损?我们认为两者兼而有之。如果我们用 7 年预测框架来审视欧元区的估值,我们发现其预期实际回报率约为 7.5-8%,这表明它目前比公允价值便宜约 15%。既然欧元区要从当前水平上涨 30% 才能达到总损失 13% 的水平,为什么它没有更便宜呢?部分原因在于,我们使用的假设比 2007 年市场严重高估时略微严苛。这解释了约 6% 的差异。其余部分,如图表 2 所示,大约 8%,是由于我们估算的欧元区股票迄今已发生的资本减损。

One exception is banks, which since the market high in 2007 have fallen about 60% in real terms in both U.S. and EAFE markets. Banks are an odd case with regard to capital impairment. First, they are highly levered entities where small changes to assets or liabilities can lead to large changes to equity values. Second, they were large holders of a number of the overpriced assets in 2007, principally corporate debt and mortgages, which is not a problem faced by non-financial companies. And third, due to their leverage, there is a very dangerous feedback loop that can arise when they take losses. Those losses force them to raise equity capital, and if the losses are big, investors will punish them by pushing their valuation below book value. Recapitalizing a levered entity below book value tends to be quite dilutive to shareholders, and this dilution is a permanent impairment of capital. So if you have a bunch of highly GMO 19 When Bad Things Happen to Cheap Assets – July 2012 Exhibit 1 Impairment of Capital for S&P 500 since 2000 2.0 Cum ulative Real Return 1.5 5.7% Real 57% Grow th Im pairment of Capital 1.0 S&P 500 0.5 200 0 200 1 200 2 200 3 200 4 200 5 200 6 200 7 200 8 200 9 201 0 201 1 201 2 Source: S&P, BLS As of 6/30/2012 levered entities that are bound to give you a permanent impairment of capital in the event that they take large losses on their assets, and they are holding assets that are substantially overvalued, there may not actually be a valuation level at which you can call them “cheap.” Once they have taken their losses it is a different matter, and it is possible that the financials are cheap today. For our part, we are still somewhat leery of them since it is not entirely clear what other dangers still lurk on their balance sheets.1 The other possible exception is eurozone equities. They have fallen less than the banks – the eurozone ex-financials is down a “mere” 33% from its high in real euro terms. As of October 2007, our forecast suggested that EAFE ex-Japan needed to fall 33% to hit fair value. Assuming the eurozone was priced similarly to the rest of the non-U.S. markets at the time, that suggests that if the markets were at fair value today and there was no impairment of capital, it should have lost 13% (a 33% hit to valuations, but 4.7 years of dividends and real sales growth should have dampened the pain by now). So, is the eurozone cheap, or has it suffered some permanent impairment of capital? We believe it is a combination of both. If we look at the valuation of the eurozone on our 7-year forecasting framework, we see it as having an expected return of around 7.5-8% real, which suggests it is currently about 15% cheaper than fair value. Why is it not cheaper, given that the eurozone would have to rise 30% from here to get to a total loss of 13%? A piece of this is due to the fact that we use slightly tougher assumptions than we did when markets were very overvalued in 2007. That explains about 6% of the discrepancy. The rest, which is about 8% as can be seen in Exhibit 2, is due to our estimated impairment of capital to date for eurozone stocks.

当考虑到美国大萧条似乎仅导致了约 4 个点的价值减损(原因是 1930 年代派发的股息低于均衡水平),那么 8% 的减损幅度实际上是个相当大的数字。² 但迄今为止的减损只是故事的一部分。我们还需要追问一个问题:未来可能还会出现多少减损?欧元区股票如今究竟是真实折价 14%,还是市场正确地预估到,正在持续的危机将对其长期价值再砍去一块?为了回答这个问题,我们全球量化股票团队的安东尼·赫恩牵头开展了一项欧元区情景分析工作¹——这还不算危机前后及期间那些见不得光的操作可能引发的更多罚款和诉讼损失。² 根据 1931-1941 年间低于趋势水平的股息计算,损失为 4%。而事实是,这一损失被以下情况完全抵消:在那段时期的大部分时间里,市场相当便宜,因此你那比预期更少的美元股息实际上买入了比预期更多的股票,从而助力复利滚出了更高的回报。

An 8% impairment is actually a pretty big number when one considers that the Great Depression in the U.S. seems to have caused about only four points of impairment, due to lower than equilibrium dividends paid in the 1930s.2 But impairment up until today is only part of the story. We also need to ask the question of what impairment there may be going forward. Are eurozone stocks actually 14% cheap today, or is the market correctly estimating that the ongoing crisis will knock another chunk out of their long-term value? In an attempt to answer that question, Anthony Hene of our Global Quantitative Equity group has led an effort into scenario analysis for the eurozone, 1  Not to mention the potential for further fines and litigation losses driven by shady practices before, during, and after the crisis. 2  Based on lower dividends relative to trend from 1931-41, the loss was 4%. As it turns out, this loss was more than compensated for by the fact that the market was quite cheap for most of that period and therefore your smaller than expected dollar dividends actually bought a larger than expected quantity of stocks, helping compound out greater returns.

While this analysis does not pretend to be definitive, it suggests the potential for a further 10-15% impairment in the event of large-scale government defaults or a euro breakup scenario, versus minor impairment if the eurozone takes an inflationary route to sustainability. It should be noted that this 10-15% impairment is an analysis across all non-financial companies and countries in the eurozone. Some companies would undoubtedly go bankrupt in a government default or breakup scenario, and some countries will fare significantly worse than others. And it is very likely that in the event of a bad outcome, the prices of the stocks would fall by more than 15% as myopic investors overreact to the bad news. But across the whole of the eurozone, 10-15% further impairment is at least an educated guess as to the permanent impact of a bad end to the crisis. Another way of putting the 10-15% possible impairment would be to say that current valuations of non-financial stocks in the eurozone broadly discount an ugly endgame for the region. If something less bad than that occurs, the stocks are at least mildly cheap. Believing this, after the market fall of April and May we bought a decent chunk of European stocks in our asset allocation portfolios. In our Global Asset Allocation Strategy, benchmarked to 65% MSCI ACWI/ 35% bonds, we have a 5% overweight to eurozone equities. This is a significant bet, bigger than our overweight to emerging equities (2%) and similar to our overweight to Japanese stocks. It is not, however, particularly close to our maximum weight in the region because, while “somewhere between fair value and mildly cheap” is a pretty good deal relative to U.S. stocks, global bonds, or cash today, it is not exactly a table-pounding endorsement. We stand ready to buy more eurozone stocks should prices fall significantly from here, but at the moment it is not particularly close to qualifying as a “Big Bet” in the GMO mold.

鉴于欧元区 6 月出现不错的反弹,以及价值股在本季度的优异表现,第二季度对于我们的资产配置策略而言在相对业绩方面算是不错的一个季度:基准策略跑赢 1%–2%,因此基本收复了第一季度的失地。绝对业绩为负,因为 ACWI 本季度下跌超过 5.5%,因此我们偏向多头的绝对收益导向型策略表现艰难,亏损在 -0.1% 至 -1.4% 之间,视策略而定。只有多策略和均值回归策略(目前它们的贝塔值接近零,因此不受整体股市低迷影响)勉强取得了正收益,分别上涨约 1% 和 3%。

Given the decent rally in the eurozone in June and quality’s outperformance in the quarter, the second quarter was a pretty good one for our asset allocation strategies in terms of relative performance, with the benchmarked strategies outperforming by 1-2% and thus making up most of the ground lost in the first quarter. Absolute performance was negative given that ACWI was down over 5.5% in the quarter, and consequently our long-biased absolute return oriented strategies struggled with losses of -0.1% to -1.4% depending on the strategy. Only the Multi-Strategy and Mean Reversion Strategies, which have an approximate zero beta at the moment and were therefore unaffected by the general equity malaise, eked out absolute gains, rising about 1% and 3%, respectively.

GMO 21 《当坏事降临廉价资产》——2012 年 7 月 简要谈谈我们在当前环境下的资产配置和量化全球股票策略。我们已习惯于我们的股票策略在市场下跌时往往能跑赢大盘,这一趋势近年来因我们大量超配高质量股票而进一步强化。如果我们逐步转向更多欧元区股票,尤其是欧元区价值股(它们目前的估值最具吸引力),那么我们的几项股票策略在下跌日跑输大盘的可能性就会增加,尤其是如果下跌是由欧元区问题(它从来不缺问题)推动的话。大多数时候,更便宜的股票在下跌时具备相当不错的防御性,但这一次可能会有一段时间走向相反方向。

GMO 21 When Bad Things Happen to Cheap Assets – July 2012 A quick word on our AA and quantitative global equity strategies in the current environment. We are accustomed to our equity strategies tending to outperform when markets fall, a tendency that has only been intensified in recent years given our large overweight to quality stocks. As and if we shift more toward eurozone stocks, particularly the eurozone value stocks, which today have the most enticing valuations, it becomes more likely that several of our equity strategies may underperform on the down days, particularly if the downdraft is driven by problems in the eurozone (of which there is no shortage). Most of the time, cheaper equities are fairly defensive on the downside, but this may be one of those times when it may go the other way for a while.

在下跌时跑输大盘,既可能是因为坏事确实降临廉价资产,也可能是因为市场会产生膝跳反应,假设坏事正在发生——无论这些坏事实际是否发生。持有欧元区资产无疑是眼下令人神经紧张的一件事。如果我们判断正确,那么对于欧元区非金融股的投资者而言,因金融危机和欧元区解体共同导致的永久性资本减值可能在 17%–22% 左右。这是一个很大的数字,远远超过美国大萧条的影响。坏事确实可能降临廉价资产,作为价值型管理者,我们需要警惕这种可能性,并相应管理我们的组合。但我们所讨论的损失,与由市场估值过高驱动的减值(例如 2000 年的标普 500 指数或 1989 年的日经指数,分别给投资者造成约 55% 和 75% 的损失)相比,就显得微不足道了。作为尽责的投资者,我们纠结于所有导致资本减值的路径。但如果你只能选择一条路径来关注,从历史上看,估值过高几乎肯定是比基本面恶化大得多的减值驱动因素。

Underperformance on the downside would likely be both because bad things were actually happening to cheap assets and because the market will have a knee-jerk response assuming bad things are happening, whether or not they actually are. Owning the eurozone is undoubtedly a nerve-wracking activity at the moment. If we are right, the permanent impairment of capital due to a combination of the financial crisis and breakup of the eurozone could be something on the order of 17-22% for investors in eurozone non-financial stocks. This is a big number, and far larger than the impact of the Great Depression in the U.S. Bad things can indeed happen to cheap assets, and as value managers we need to look out for this possibility and manage our portfolios accordingly. But the damage we are talking about pales in comparison to the impairments driven by overvalued markets such as the S&P 500 in 2000 or the Nikkei in 1989, which cost investors about 55% and 75%, respectively. As conscientious investors, we obsess about all routes to capital impairment. But if you only had to choose one route on which to focus, across history, overvaluation has almost certainly been a much bigger driver of impairment than deteriorating fundamentals have been.
