GMO 季度信函,2002 年 10 月,主席 杰里米·格兰瑟姆 泡沫破灭——第七部分:轻松阶段结束 对经济和市场的评论完整版。 格林斯潘对泡沫有责任这一说法令人发指地否认——有时甚至与他早期言论公然矛盾——又引发了一波分析浪潮。 全球股市的第三季度是自 1937 年以来最残酷的季度之一,也是 9 月表现最差的一个月。全球经济似乎至少有些疲软,风险也高于正常水平。日本和德国似乎尤其无法解决自身问题。与伊拉克开战的威胁也无助于事。 总体影响是,所有投资者,无论是机构投资者还是个人投资者,都感到被我们金融和政府体系中太多的组成部分所背叛。商业世界,不久前还是全世界的羡慕对象,却因道德妥协甚至公然欺骗的程度而继续让所有人失望,包括我们 GMO 在内。投资者似乎没有得到公平的对待,尤其是个人投资者,但机构投资者亦不例外。太多环节——高层管理人员和华尔街的许多部分——不仅把自己的利益放在首位,而且以自 1920 年代末以来未曾见过的对客户和股东的蔑视态度行事。 今年,利己行为的层层伪装已一点点被揭开。总统过去的公司行为显然并非无可疑之处。很明显,许多国会议员(以参议员利伯曼为首),他们总体上看起来相当合理,但确实将他们的竞选捐款人置于金融体系的诚信之上,阻挠了改革会计准则和会计事务所的努力。 围绕格林斯潘也发现了更多的确凿证据。他似乎真的相信过泡沫的危险;甚至一度相信泡沫存在。他当时至少认为他有遏制泡沫的工具,主要是通过提高保证金要求。他没有这样做并不很奇怪,因为他会承受巨大的政治压力,但令人失望的是,他没能更加强硬。可以肯定的是,他的职责描述中绝没有让他成为新经济如此雄辩的倡导者这一条。(我对格林斯潘的看法附在另一篇文章中。) 后果将是深远的,而且已经加快了市场向公允价值必然回调的步伐。在某个更晚的时点,这种失望情绪可能会在决定市场会多大程度超越公允价值方面扮演一个不幸的角色,因为市场很可能会超越公允价值,就像我们发现历史上没有例外于这种过度倾向一样。 重复我们通常的主要观点,泡沫的形成和破裂是迄今为止市场历史上最重要的时刻。如果一切做得正确,总会有很多痛苦。如果任何事做错了,就会有更多痛苦。这次我们做错了多少事,越来越令人印象深刻且惊讶。 市场板块 本季度,全球危机感日益强烈,从季度中期到 10 月,几乎所有国家(包括美国)的优质股开始大幅跑赢大盘。与危机中较低质量相关的小盘股和价值股开始在所有地方表现不佳,除了澳大利亚,有趣的是,澳大利亚能够更长时间地坚守小盘股和价值股的老主题,并且还跑赢了大多数市场。 美国的价值股跑输了极度疲弱的标普 500 指数(-17.3%)1.4 个百分点,价值股跑输成长股 3.7 个百分点,这可能是价值股在两位数的熊市季度中表现最差的一次。

(My views on Greenspan are attached as a value has done in a double-digit bear quarter since the separate piece.)

1930 年代。这种相对表现不佳迟早会发生,但偏偏在一个如此疲弱的市场中发生,时机确实不同寻常。2000 年 3 月,价值股与成长股之间的差距达到了前所未有的程度,到 2001 年 9 月已基本消失。在 2001 年第四季度成长股反弹之后,这一差距在 6 月 30 日之前已恢复正常,甚至进入过度区——这是典型情况。小盘股也在 6 月前完成了同样前所未有的差距弥合。这两项押注的防御性表现——在持续下跌的市场中前 21 个月逆势上涨——比我们合理预期的还要令人印象深刻。在第二季度的信中,我曾提到,这两项资产在绝对意义上都被严重高估,很可能会经历严重的绝对痛苦,特别是因为它们对标普 500 指数的周期性敞口要大得多,而经济仍非常容易受到低于预期增长的影响。原话是:“随着市场继续下行,这两个板块都将失去其防御性的大部分。”我当时完全没想到,这个考验会来得如此之快,而“大部分”这个说法会显得如此保守。话虽如此,我们预计,在这轮熊市结束时,价值股和小盘股都将创下新的相对高点,但过程中波动会更大,也会经历一些非常痛苦的时期。

在国际市场上,小盘股和价值股从相对高点回落,但本季度仍保住了微弱优势。

我们对标普 500 指数的公允价值估算是 670 点,对纳斯达克指数的估算是 1050 点。这与 10 月初的低点之间的差距几乎可以忽略不计。纳斯达克指数从 5050 点跌至 1050 点的痛苦已基本完成 99%,标普 500 指数从 1550 点跌至 670 点的痛苦已完成 83%。我们现在都需要担心的是过度修正的程度。如果修正幅度很大——这有可能——它可能还会与已经脆弱的全球格局产生相互作用。

资本配置

上述大部分损失早在第三季度之前就已发生,但在该季度,一个个小碎片逐渐拼凑起来,画面变得越来越清晰,这是我们在从事资产配置的 12 年里首次出现的情况。一些非美国成分股(如小盘价值股和新兴市场股)的潜在 7 年期回报已变得相当具有吸引力。其不利之处在于,如果美国市场下跌,任何外国股票成分实际上涨的可能性都微乎其微,接近于零。但是,在一项预期实际回报率为 13%(升至 17%)的资产中承受痛苦,要好过在美国资产中承受痛苦——其实际回报率仅为 2% 至 6%(顺便说一句,再有两个 9 月的跌幅就能达到这个水平)。美国与非美国股票之间的价值差距,实际上已是 40 年来最便宜的水平(图表 1)。美国股票与非日本 EAFE 指数之间过往的走势幅度大且持久,而最近一次美国股票上涨是持续时间最长的。图表 2 显示,周期可能已转向有利于非日本 EAFE 指数,即使尚未转向,我们也预计它很快就会转向,并出现一次持续多年的大幅反向走势。资产配置三大基石中有两项之间的这一差距,可以为未来几年带来可观的价值增值提供燃料,但一如既往,均值回归这条真爱之路不会平坦。我们目前对 7 年期的偏好是:非美国股票第一,固定收益产品遥遥领先地排在第二,美国股票第三。即使在美国股票内部,REITs 也远好于固定收益产品,小盘价值股可能略好一些。事实上,固定收益产品凭借自 2000 年 3 月以来的出色表现,已变得严重高估。通胀保值美国国债(TIPS)的实际收益率在经历了两位数的年化回报后,已从诱人的 4.1% 降至相当节俭的 2.4%。如果股票市场的危机模式持续下去,即使从当前水平出发,它们可能仍会表现良好,但合理的 7 年规划要求逐步退出这一领域以及常规政府债券的押注。

不过,第三季度在某些艰难局面下还是出现了积极迹象。非美国股票多年来首次变得绝对便宜,并且比固定收益证券更便宜,而高价债券与危机模式下的股票(尤其是定价过高的美国股票)之间的紧张关系,最终迫使我们持有了一些现金及现金等价物。过去 12 年来,EAFE(不含日本)综合估值相对于标普 500 综合估值,以及新兴市场相对于美国市场的估值比率,终于出现了这一转折。

日本仍然是那个巨大而危险的谜团。终于出现了正采取更严肃纠正措施的迹象。这是必要的第一步。安德鲁·史密瑟斯十年来一直主张,没有真正的危机,日本永远不会采取严肃行动。与此同时,日本股市处于 19 年低点,但反常的是,它却是今年主要股票市场中跌幅最小的。由于内在不确定性,我们决定对日本维持中性配置,这一决策今年效果良好,释放了我们的时间和风险单位,用于更可靠的押注。

GMO 第三季度业绩

第三季度与头两个季度不同,远非易事,连那种相对难啃的“蛋糕”都算不上。鉴于不利的环境,GMO 的相对业绩在外国股票中表现良好,在资产配置中略好,在美国股票中令人失望地出现回撤,在新兴市场股票中遭遇亏损。国际内在价值策略本季度跑赢 4.9%(年初至今超 +16%),资产配置策略(全球平衡型)跑赢 2.7%(年初至今超 +12%),美国核心策略仅勉强实现令人失望的 +0.1%(年初至今 +1.6%),新兴市场策略表现不佳。

我们很清楚,我们正在进入一个困难时期,正如我们两年来一直说的,我们最可能犯的错误是过早投资于那些虽然已经便宜但价格仍在继续下跌的股票——这与 1997 年至 2000 年的情况正好相反。问题在于,过度阶段再次成为一种博傻现象,而我们更倾向于在 7 年周期上押注有价值的赌注。不过,我们已经学到,一定的惯性是好事,我们在资产配置中总是行动缓慢。话虽如此,今年我们在固定收益上的早期减持,降低了我们在资产配置中的超额收益。另一种选择是押注一定程度的过度上涨,那等于用直觉(即便是基于历史趋势和观察的合理直觉)去交换均值回归的近乎确定性。这就是我们计划做的事:当股票价格低于公允价值时,我们会买入股票,但我们会缓慢行动。在对股票大幅超配之前,我们将等待股价跌穿我们的常规标准——超过 1 个标准差——在此期间,我们将保持接近基准配置。

However, we have learned that some our time and our risk units for more dependable bets. inertia is a good idea and we always move slowly in asset allocation. Having said this, our early reductions in fixed GMO’s Third Quarter Performance income during the year have reduced our outperformance The third quarter, unlike the first two, was far from a in asset allocation. To do the alternative, which is to bet piece of cake, even the hard to eat relative piece of cake. on a certain degree of overrun, is to trade off a hunch GMO’s relative performance, given the unfavorable (even a likely hunch based as it is on historical trends, was good in foreign, modestly good in asset observation) against the near certainty of eventual mean allocation, a disappointing draw in US equities, and a loss reversion. This is what we propose to do: we will move in emerging equities. International intrinsic value into equities as they pass fair value but we will do it outperformed by 4.9% for the quarter (over +16% year- slowly. Before we overweight equities materially, we will to-date), asset allocation (global balanced) outperformed wait for stock prices to undershoot by our usual 1+ by 2.7% (over +12% year-to-date), US Core eked out a standard deviations, during which time we will stay close disappointing +0.1% (+1.6 year-to-date) and emerging to the benchmark.

3 GMO 季刊 – 2002 年 10 月 GMO 专题 2002 年 10 月 杰里米·格兰瑟姆,董事会主席 泥足巨人 艾伦·格林斯潘对美国大股灾的贡献 ——美国大股灾系列文章之一—— 引言:美联储主席的职责是什么?

在早期,美联储似乎把重点放在经济活动上,这是对 1930 年代高失业率以及二战后经济萧条担忧的合理回应。到了 90 年代,在经历 1973 至 1983 年高通胀的阵痛之后,重心转移到控制通胀上。这两个因素在它们看起来对稳定至关重要的时期都得到了强调,而我相信,美联储的根本职责很可能是、也理应是维护总体经济的稳定。

没有什么比一场大型股市泡沫的潮涨潮落更威胁经济稳定的了,尤其是在这次泡沫破裂之前就已经存在全球通缩风险的情况下。这种严重风险让“泡沫难以察觉”的论点相形见绌,因为赌注实在太高,连尝试都不做不行;大型泡沫在大多数情况下就像平原上突起的山峰。将 36 倍市盈率与 1929 年之前的 21 倍峰值以及 75 年平均的 14 倍相比,似乎并不需要特别敏锐的分析技巧。潜在的危险压倒了格林斯潘的辩解,即对抗泡沫的技术并不精确——经济学里有什么是精确的呢?美国经济的稳定,只有在美联储及其主席愿意在罕见的时刻承担一些实质性政治风险的情况下,才能免受泡沫破裂带来的真实危险。他们必须尝试识别并遏制大型泡沫,并准备好承担一些后果。如果他们不准备这样做,那么经济的风险水平将大幅上升。

This in turn increases on economic activity, a reasonable response to the high corruption a little and unethical behavior a lot.

场景设定 大牛市的负面影响实际上始终会验证墨菲定律:但凡可能出岔子的事,偏偏就在这个时候爆发。大规模股市泡沫对经济而言堪称最危险的事情。它们在热门领域引发浪费性的过度投资,并通过创造的巨额账面财富大幅增加泡沫风险。由过高股价和过度放贷导致的过度投资,随后将引发资本支出崩溃。某种程度上感到被背叛的投资公众会丧失投资信心。由高股价推动的过度放贷将会趋于枯竭,同样枯竭的还有受股价上涨和美国经济繁荣双重鼓励的外国投资。这些因素中的许多会相互作用,人们永远无法预知情况会糟糕到何种程度。当然,股价本身总是会过度修正到趋势线价值之下。基于所有这些原因,应当不惜一切合理代价避免泡沫。为了降低出现大型泡沫的可能性,值得在经济和职业层面冒一些风险。最有可能采取有效行动的人物是美联储主席艾伦·格林斯潘。本文的目的在于评估他的表现并给他打分。

美国在 1927 年经历了一场温和的收缩,美联储便增发了更多纸币储备,以期防范可能出现的银行储备短缺。他是否预见到了泡沫的来临?他又能做什么?美联储向经济中注入的过量信用蔓延至股市,引发了一场离奇的投机狂潮。导致 1995-2000 年泡沫形成与破裂的因素有很多,那是美国历史上迄今规模最大、也最为重要的泡沫。许多事情要么做得很糟,要么根本没做,但我认为,事实和常识表明,对我们当前困境贡献最大的单一因素确实是艾伦·格林斯潘,因为只有他拥有阻止或削弱这场股权泡沫的权力。美联储官员们姗姗来迟地试图吸收过剩储备,最终成功遏制了这场繁荣。但为时已晚:到 1929 年,投机失衡已变得势不可挡,这次尝试反而引发了一场急剧的紧缩,并随之导致商业信心崩溃。

结果,美国经济——格林斯潘本可以在 1996 年小幅加息时就那么做……"他显然在指责美联储,既导致了繁荣,也引发了随后的崩盘。他还大谈特谈抑制资产价格泡沫的决心。最明显的一点或许是,他本可以提高保证金要求。如果格林斯潘当时准备好运用所有可用工具并展现他的决心,那几乎肯定能奏效,并且会切掉美国股市上涨和随后下跌中最后一波实质性的行情。此外,这还会减少伴随一场真正重大泡沫而来的过度投资、贪婪和腐败。J.K. 加尔布雷思,很可能不带任何偏见,研究了 20 年代末上一次重大股市泡沫,并撰写了《大崩盘》(约翰·肯尼斯·加尔布雷思,《大崩盘,1929》,第 189-194 页,纽约,马利纳出版社,1997 年)一书,他的分析以一个响亮的结论收尾:美联储确实拥有防止重大泡沫的工具,但他似乎有先见之明地指出,这些工具永远不会被使用!

他辩称,“投机狂热(比如引发 1929 年大崩盘的那种)再次上演的可能性仍然很高。没有人怀疑美国民众依然容易受到投机情绪的感染……政府的预防措施和控制手段早已就位,在意志坚定的政府手中,其效力毋庸置疑。然而,有上百种理由说明政府可能会决定不使用这些手段……采取行动刺破繁荣,必须始终权衡其可能在一个政治不合时宜的时刻引发失业的风险。”

就在我努力梳理思绪、思考此类投机狂潮重演的可能性时(像是导致格林斯潘失策的那种),他却以令人瞠目结舌的无耻态度,在今年 8 月杰克逊霍尔的会议上彻底否认了对泡沫的责任,完全超越了我的努力。

按照格林斯潘的说法,对市场进行口头干预“若无行动支撑,将会无效”。这一点我们倒能达成一致。他声称,认为“时机恰当的渐进式”加息本可阻止泡沫,这种信念是站不住脚的。

He argued “that the chance for While I’ve been trying to marshal my thoughts on the recurrence of a speculative orgy (like that leading up to Greenspan fiasco, he has overtaken my efforts with his 1929) remains good. No one can doubt that the American breathtakingly shameless and complete denial of people remain susceptible to the speculative mood … The responsibility for the bubble at Jackson Hole in late government preventatives and controls are ready.

He claimed that the belief that “well- chance that it will cause unemployment at a politically timed incremental tightening” of rates could have inopportune moment.

这在任何时候都会显得如此——就像它在反对“20 世纪 90 年代末的泡沫几乎肯定让美联储董事会在 2 月吓破了胆”这一观点时表现的那样,该观点认为泡沫是一种幻觉。更具争议的是,他认为 1929 年提高保证金要求的决定,如同支持立即面对死亡而非延缓之策,最终也会导致毁灭。正如我们所看到的,立即死亡并非毫无影响。他进一步质疑,即便 GMO《泥足巨人》一文(2002 年 10 月)所识别的行刑者规模,其劣势也不仅在于来得快,还在于其作用有限。人们可能会预期……随着对新经济、其历史新高的生产率、盈利能力和增长水平,以及为更高股价提供理由的日益热情,银行家和经纪商会要求美联储将保证金比例提高到极限……公众将敏锐地被告知买入股票以博上涨所固有的风险,而这一切按理都可能发生。然而,在 20 世纪 90 年代末的狂飙年代,这并未发生。不过,格林斯潘虽然并未卖股,但他似乎比任何人都更彻底地相信这一套新经济胡话,到 2000 年 3 月时更是如此。

It will always look, as it did to the succeeded against “the late 1990s bubble is almost surely frightened men on the Federal Reserve Board in February an illusion.” Even more controversially, he argued that 1929, like a decision in favor of immediate as against increasing the margin requirement would also have had ultimate death. As we have seen, the immediate death not little effect. He further asked whether even the size of the only has the disadvantage of being immediate but of GMO 2 Feet of Clay, October 2002 identifying the executioner … One might expect that … increasing enthusiasm for the new economy, its new high The Federal Reserve would be asked by bankers and plateau of productivity, profitability and growth, and its brokers to lift margins to the limit … The public would be justification for higher stock prices.

遗憾的是,对所有人而言,这听起来都太过明确地指向一个泡沫——尽管他本人就像现任美联储主席一样。格林斯潘在 1996 年 9 月声称自己识别出了一个泡沫,而即使在今天,他也承认当时“强烈怀疑”市场在最终价格还不到一半时就已经在他看来是非理性的了。他接着说:“没有任何货币紧缩措施……能够可靠地戳破泡沫。”不,当然,货币紧缩不会‘可靠地’起作用,但结合口头干预和提高保证金要求(他声称知道这会有用),它很可能就会奏效。保罗·克鲁格曼最近指出了格林斯潘在 1996 年对公开市场委员会同事的惊人声明:“我认识到,此刻存在一个股市泡沫问题。我们确实有可能……戳破它。”

This unfortunately for everyone sounds all too definitely identify a bubble, although he himself had like the present Fed Reserve Boss. claimed in September 1996 to have identified one, and Greenspan himself back in 1996, when the market at even now he confesses to “strongly suspecting” that one under half its final price was already irrational in his eyes, existed then. “No monetary tightening … can reliably lets on that a bubble can indeed be broken. Paul Krugman deflate a bubble,” he went on. No, of course monetary recently pointed out Greenspan’s remarkable September tightening would not have ‘reliably’ worked, but together 1996 statement to fellow Open Market Committee with jawboning and increased margin requirements colleagues, “I recognize that there is a stock market (which he claimed to know would work), it very probably bubble problem at this point. We do have the possibility would have worked.

保证金要求不断膨胀的泡沫后果,我也向你保证,如果你要打破它,无论采取何种方式,后果通常都很严重。在处理这一问题的任何负责任工作中,这都只是若干确凿证据之一。在经济学和金融学这类软科学中,确定性是过高的要求。他的工作就是尽最大努力应对不确定性,而在这一点上他彻底失败了。尽管他认为泡沫很危险且后果可能具有毁灭性,尽管他明知自己有工具可以打破泡沫,尽管早在 1996 年——可能恰是行动的最佳时机——他就察觉到了这一点,他却没有采取行动,让我们承受痛苦的后果,其中最糟糕的莫过于不得不听他的借口,并看到那么多信徒愿意点头附和。格林斯潘的摇摆不定和变卦,可能源于一些混乱的思考,尽管很难将混乱思考与为了顺应政治便利而改变论点的倾向区分开来。

有两个典型例子。

首先是他对市场效率的看法。1966 年时他认为,过度行为或泡沫确实存在,可以被识别并采取行动。但在因“非理性繁荣”判断失误而被国会议员当头棒喝之后,他急忙转向,采纳了市场有效论来自保:“要提前识别泡沫,需要做出比数十万名投资者都更正确的判断。”

那么格林斯潘为何不在喊出“非理性繁荣”之后继续跟进呢?加尔布雷斯大概一语道破:没有人想成为那个被抓住“握紧别针”的人。没有人愿意承受巨大的政治压力,而我们都知道格林斯潘因为那句“非理性繁荣”已经惹了不少麻烦。在那种压力下犹豫不决是合理的,而对泡沫的处理犹豫不决,就好比有人比喻的那样——你在伦敦公交车上跳下去的那一刻还在犹豫。

There are two prime examples. First, his view of market Why did Greenspan not follow through after “irrational efficiency. His 1966 view is that excesses or bubbles do exuberance?” Galbraith probably had it nailed. No one indeed exist and can be identified and acted on. After wants to be the one caught “holding the pin.” No one having his head slapped by congressmen for his looks forward to taking a lot of political heat and we ‘irrational exuberance’ miscalculation, he hurriedly know that Greenspan took a good deal because of moves to cover his tail by adopting a view that the market “irrational exuberance.” Hesitating under that pressure is is efficient: “to spot a bubble in advance requires a reasonable, and hesitation in dealing with a bubble has judgment that hundreds of thousands of investors have it been likened to jumping off a London bus as it all wrong.”

然而,他在 1996 年早些时候的疑虑进一步加深。这起初是个令人不快的命题,但一旦你拖延下去,它就变得极其危险。在这样的时刻,一厢情愿的思维成为一种诱人的选择,而格林斯潘似乎确实深陷于这种一厢情愿之中。作为新经济时代的信徒,在坚持不懈和不断抛出惊人预测方面,只有高盛的阿比·科恩和雷曼兄弟的杰夫·阿普尔盖特等少数卖方策略师能紧随其后。他最初的说法听起来像是彻底相信市场无效。到了 2002 年夏天,他又回到了早先的观点:“历史证明,投资者常常夸大经济基本面改善的程度。人性使然,泡沫往往会自我强化,繁荣后期往往由不切实际的潜在需求预测所支撑。”“不切实际的预测!”

Yet his suspicions in his earlier 1996 accelerates. It is at first an unpleasant proposition, but as statement did sound like flat-out belief in an inefficient soon as you delay it becomes just plain dangerous. At market. Now in the summer of 2002 he returns to his such times, wishful thinking becomes an appealing earlier view: “history attests, investors too often proposition, and Greenspan seems genuinely to have exaggerate the extent of the improvement in economic been deep into wishful thinking. As a believer in the new fundamentals. Human psychology being what it is, era, only a few sell-side strategists such as Goldman bubbles tend to feed on themselves and booms in later Sachs’ Abbey Cohen and Lehman Brothers’ Jeff stages are often supported by implausible projections of Applegate ran him a close second for relentless and potential demand.” “Implausible projections!”

这里是他的阿喀琉斯之踵,2002 年 10 月 3 日 GMO 听起来像一位行为主义者,认为市场是一只宠物。“股票价格高企,”他说,“降低了资本成本。其结果是对高科技设备的支出出现了一场名副其实的爆炸……我看不到任何迹象表明这些机会会在短期内消退……事实上,许多人认为创新的步伐将继续加快……以充分挖掘电子商务的巨大潜力,尤其是企业对企业领域。”所有这一切都发生在格林斯潘的言论发表后一周内,但他的另一项突出的智力混乱之处涉及资本成本。他的新辩护包括一种表面上的信念,即生产率提升或许能让企业利润以足以证明新高股价合理性的速度增长。这是一个相当常见的错误,但对格林斯潘而言却显得异常业余。

Here he Feet of Clay, October 2002 3 GMO sounds like a behavioralist who believes the market is a pet. “Lofty equity prices,” he said, “have reduced the cost dangerous jungle of psychological impulse! of capital. The result has been a veritable explosion of spending on high-tech equipment … And I see nothing to His other remarkable intellectual woolliness regards the suggest that these opportunities will peter out anytime cost of capital. His new defense includes an apparent soon … Indeed many argue that the pace of innovation belief that productivity improvements might permit will continue to quicken … to exploit the still largely corporate profits to rise at a rate that would have justified untapped potential for e-commerce, especially the the new high stock price. This is a common enough error, business-to-business arena.” All this within one week of but an oddly amateurish one for Greenspan.

如果纳斯达克“虚高价位”下跌的顶点确实让利润率 —— 进而让企业回报 —— 永久性地改善了 75%,而企业对企业子指数跌幅超过 95%,那么股东的回报也必然随之提升 —— 而这只有在股价更低、收益率更高的情况下才会发生,而不是股价更高时。这种反直觉的结果,不过是在说资金成本必须与资本回报保持平衡。没有这种平衡,就会形成经典的资本主义套利。如果股票回报高于资本回报,那么资金会持续流入,直到两者平衡。格林斯潘热情高涨的经济基础始终看起来摇摇欲坠。不是说经济和生产力表现不佳 —— 它们比 70 年代、80 年代和 90 年代初期好得多。只是看起来并没有格林斯潘认为的那么好。

If indeed the peak from which the Nasdaq’s “lofty prices” declined profit margins, and hence return to corporations, had by 75% and the business-to-business sub index fell by improved in a permanent way, then return to stockholders over 95%! must also improve - and this only occurs with lower stock prices and higher yields, not higher prices.

They were much better than the seventies, Without this balance, there is set up a classic capitalist eighties, and early nineties. It simply did not seem to be arbitrage. If the return to stocks is higher than the return as good as Greenspan believed.

怀疑论者认为,格林斯潘的逻辑甚至过不了金融学基础课程的期末考试!举例而言,他们指出,享乐主义通胀调整法——这种方法认为,如果电脑速度提升四倍,就相当于实际价格下降 75%——并不现实。这种方法每年给生产率增长贡献约 0.5 个百分点,而许多相当严肃的国家并未采用。生产率增长中过大的部分来自科技资本设备领域不可持续的繁荣。生产率是按人均计算,而非按每小时计算,而在 90 年代,随着自己变得更富有,美国人和英国人成为唯一工作时间反而延长的群体。

按照格林斯潘的逻辑,如果公司对投资感到恐惧,那么就没有公司会投资——它们只会干脆在股市上买入更便宜的资产,直到新资产的短缺推高企业回报。反过来,如果公司不恐惧,那么它们就会通过出售高价股票来筹集新资本,并投资于新的工厂(令人联想到电信泡沫),从而压低新投资的回报,直到整个系统重新达到平衡。

Skeptics argued, for to corporate investment, then no company will invest but example, that hedonic inflation adjustment, which argued simply buy cheaper assets in the stock market until a that four times the speed in a computer was equivalent to shortage of new assets drives up corporate returns. a 75% reduction in real prices, was unrealistic.

Productivity was Greenspan’s logic would fail a Finance 101 final! calculated per person, not per hour, and Americans and Brits were alone in working longer in the nineties as they Greenspan: the Great Promoter got richer.

在加尔布雷思的帮助下,我们很容易理解,一个抱有政治动机的美联储主席,为何会避免对资产类别泡沫采取果断行动。我们甚至可以理解,他在若干问题上的混乱思维,也未能帮助他变得果断行事。然而,更令人费解的是,他对经济前景发表的看多言论。考虑到他公开表露的疑虑,以及对泡沫可能性的“怀疑”,他为何还会频繁地表达对经济最乐观的看法?

The rest of the developed world quite sensibly With Galbraith’s help, it is easy to understand how a worked less. This list of earlier challenges to the validity politically minded Federal Reserve Chairman would of the new economy is just a sample. In short, for many avoid taking decisive action against an asset class bubble. of us, the case for a permanent and significant We can even understand that his muddled thinking on improvement was possible but absolutely not proven, and several issues would not have helped him be decisive. the degree of improvement was seen as entirely unlikely Much harder to understand, though, are his statements of to rival Greenspan’s vision. bullishness about the economy. Given his stated Whatever Greenspan’s motives for voicing his misgivings and “suspicions” on the probability of a enthusiasm for the new economy, we know what its effect bubble, why would he frequently make the most was.

这个说法消除了大多数投资者的合理怀疑。关于新《金融时报》的过度乐观言论——顺带一提,该报获得"对广大公众最不经济"奖——考虑到他的地位,他难道不是在拍各大报纸的马屁,关于格林斯潘,他难道没想过这些话会被当作火上浇油?过去 5 年里,他难道没有指出,他"越来越意识到这会助长恰恰是他现在归咎于泡沫的那种‘夸大’的乐观看法……很可能助长了 1990 年代末的过度繁荣",难道他真的认为监督资产泡沫不属于他的职责范围,而发表这些言论才是?摩根士丹利的经济学家史蒂芬·罗奇更进一步,认为格林斯潘直言不讳地相信这个周期具有独特特征——快速增长同时低通胀——本身就值得反思他某些言论的极端性。

It removed reasonable doubt for most investors. The extravagantly optimistic statements about the new Financial Times, who incidentally get the award for least economy to a broad public? Given his status, did he not boot-licking of the major papers regarding Greenspan expect this to be used as fuel for the fire? Did he not over the last 5 years, pointed out that his “increasingly realize it would encourage precisely the “exaggeration” bullish observations … may well have contributed to the of economic progress he now blames for the bubble? Did explosion of exuberance in the late 1990s.” Morgan he really see this as being in his job description whereas Stanley’s economist, Stephen Roach went further, controlling an asset class bubble was not? arguing that Greenspan’s outspoken belief in the unique It is worth reminding ourselves of the extravagance of features of this cycle – rapid growth yet low inflationary some of his statements.

例如,在 2000 年 1 月,他(的压力)消除了加息之需。格林斯潘声称“美国经济正经历百年一遇的创新加速,这股势头推动生产力、产出、企业利润和股价以几代人未见的步伐前进,如果说此前有过的话。”好家伙!互联网,那个为“公司驱散不确定性迷雾”的东西,成了他的心头好。GMO《泥足巨人》,2002 年 10 月

说到底,格林斯潘面对的并非道德困境。道德上很清楚:他掌握了知识、经验与信念,却没有采取行动。他遭遇的是一个职业困境。如果早早从疾驰的巴士上跳下,他会招致不小的非议。倘若经济放缓,他会被归咎责任——这份声誉,若没有抵偿回报的现实希望,仅仅因为做了正确的事就甘愿放弃,那才叫天真。

In January 2000, for example, he pressure – removed the need to raise interest rates. “That claimed that “the American economy was experiencing a was the buy signal every investor and speculator dreamed once-in-a-century acceleration of innovation, which of.” propelled forward productivity, output, corporate profits Summary and stock prices at a pace not seen in generations, if In the end, what Greenspan faced was not a moral ever.” Phew! The internet, which had “pushed back the dilemma. The morality was clear. He had the knowledge, fog of uncertainty” for corporations, was his particular experience, and belief and failed to act. What he had was GMO 4 Feet of Clay, October 2002 a career dilemma. If he jumped off the moving bus early, reputation without a realistic hope of offsetting rewards he would have taken some considerable grief. If the simply because it was the right thing to do would have economy had slowed, he would have been blamed.

采用的道德标准极高,以及对偶发性普通衰退时机的极度关注,并非性格特质中的关键要素。保罗·沃尔克或许对社会具有重要性。确实,偶尔有一位温和派人物做出了那样的选择。从长远来看,衰退或许对健康的经济是必要的,尽管你也能找到持相反观点的经济学家。社会真正的代价来自泡沫所引发的腐败、失望情绪、储蓄减少以及浪费的投资。然而,对于想要连任、而其选民对政治纲领的看法往往简单归结为“笨蛋,关键在于经济!”的政客们来说,衰退的时机才至关重要。

至于格林斯潘近期的辩护,我们最终能指望什么?指望他悔恨自己缺乏品格?还是指望他承认哪怕部分错误?他在这方面的彻底否认,让人想起 1960 年代英国普罗富莫性丑闻中的一件事。其中一名涉案女性曼迪·赖斯-戴维斯,在听说政府大臣否认与她有过性关系后,说出了那句不朽的话:“嗯,他当然会那么说,不是吗?”

The taken very high ethical standards and considerable timing of occasional ordinary recessions is not of vital strength of character. Paul Volker perhaps might have importance to society. Indeed, an occasional moderate made that choice. recession may be necessary for a healthy economy in the As for Greenpan’s recent defense, in the end what did we long run, although you could find economists who would expect? That he would repent his lack of character? That argue the other side. The real cost to society comes from he would admit even partial fault? His complete denial on the corruption, disappointments, reduced savings, and the this regard brings to mind an incident in the Profumo sex wasted investments brought on by a bubble. The timing scandal of the 1960s in England. One of the women of recessions is, however, of real importance to involved, Mandy Rice Davis, on hearing that the politicians who want to be re-elected and who face an government minister had denied having sex with her, electorate whose view of their political platforms is often replied with the immortal words, “Well he would say that, a simple, “It’s the Economy, Stupid!”

在格林斯潘的辩护下,我们会同意他几乎不会或者根本不会感谢人们阻止了泡沫与崩盘的弊端,这一点永远无法被证明。我们所知道的是,世界上许多舆论制造者(但令人鼓舞的是并非所有人)接受他的论点,仅仅是因为令人恼火。无论恼火与否,必须承认,就逃避责任而言,他似乎基本成功脱身。那些看似显而易见的道理有时会很有趣。这次,同样可以预测的是,许多人否认自身责任,并且明显轻信事情会安然度过泡沫,这种态度令人不快。因此,如果他采取行动,他的声誉和职业生涯至少会暂时受损。如果他沉溺于一厢情愿,他可能会相信事情会勉强应付过去。

In Greenspan’s wouldn’t he?” Sometimes the blindingly obvious is defense, we can agree he would have received little or no funny. This time the equally predictable denial of thanks for preventing the evils of a boom and bust for it responsibility and the apparent credulousness of many could never be proved. What we do know is the world’s opinion makers (but encouragingly not all of them) in willingness to believe that things would work out well accepting his argument are merely irritating. despite the bubble. So if he had acted, his reputation and career would have suffered at least temporarily. If he had Irritating or not, it must be conceded that in terms of engaged in wishful thinking, he could believe that there avoiding blame he appears to have mostly gotten away would be either a chance that things would muddle with it.

你确实可以“愚弄大多数人很长一段时间”,或者指望他否认责任时那些混乱矛盾的说辞能蒙混过关。这里的“大多数人”可能也包括了那位因他在全球(的所谓贡献)而最近授予他爵士头衔的女王陛下。不过,我私下里还是希望,女王陛下之所以这么做,是看在他过去三年里一直持有一个不错的空头头寸,从而替他挡掉了大量政治压力和某些短期损失。

You can indeed ‘fool most of the people all of the through or a chance that his denials of responsibility, time.’ ‘Most of the people’ this time probably included muddled and contradictory as they are, would suffice. For Her Majesty who recently knighted him for his global a Federal Reserve boss to have volunteered to have taken services. My secret hope though is that she justified it by a lot of political heat and certain short-term damage to his having had a good short position for the last 3 years.
