长江商学院曹辉宁教授荣获全球顶级金融期刊年度最佳论文奖

2011年8月8日,长江商学院金融系主任、金融学教授曹辉宁的论文《对未知的恐慌:熟悉度对经济决策的影响》,荣获由全球顶级金融学术期刊之一《金融评论》颁发的2011年“Spängler IQAM”最佳论文奖优秀奖,这篇论文近期刊登在《金融评论》(2011年7月,第3期,第15册)。该期刊之前出版的四期中的三个最佳论文分别获得了这次大奖的卓著奖和两个优秀奖。曹辉宁教授将于2011年8月19日在瑞典斯德哥尔摩欧洲金融协会的年会上接受此殊荣。

曹辉宁教授的论文中提出了一个模型,认为人们根据现状做出决定时倾向于选择最差状况。该熟悉度偏好模型可用来解释检验行为金融里的禀赋效应、投资组合低分散化、本国和本地区证券偏好以及对均衡资产定价理论进行校正。论文指出,改良后的资本资产定价模型具有充分的可用性,其中,市场证券投资组合被不受熟悉度偏好影响的投资者控股投资组合所取代。曹辉宁教授的获奖再次显示了长江商学院在亚太地区首屈一指的学术研究能力和学术地位。

在过去几年中,曹辉宁教授在全球著名期刊Journal of Finance,Review of Financial Studies,Journal of Financial Economics, Journal of Economic Theory,Journal of Business,Marketing Science and European Financial Management等发表多篇论文,并被大量引用;曾两次获得Journal of Finance的最佳论文提名(1998年和2000年);曾获Northern Finance Association评选的新兴市场领域最佳论文奖;曾获Western Finance Association 评选的最有投资价值的最佳论文奖;在2004中国金融国际年会上获得最佳论文三等奖;任Annals of Economics and Finance的编委会成员及International Financial Review和China Financial Review的主编。

曹辉宁教授于1995年在洛杉矶获得加利福尼亚大学金融博士学位,1991年获得耶鲁大学病理学博士学位。在进入长江商学院之前,曹辉宁教授还在加州大学伯克利分校、加利福尼亚大学圣地亚哥分校、俄亥俄州立大学、卡内基梅隆大学以及北卡罗来纳大学教堂山分校等学校任教。

专访曹辉宁教授:交谈能帮我们避开流行的错误吗?



一般人是怎样决定到底投资哪家公司,买哪个特定的产品的呢?是凭着理智做出选择亦或只是跟风罢了?跟风是最合理的选择吗?假如能目睹别人所做决定的结果,他们能做出更好的决定吗?

2011年7月15日-长江商学院金融学教授曹辉宁、韩冰和David Hirshleifer三位教授即将在《经济理论期刊》上发表一篇文章, 表明很多人会选择跟随别人,即便这样做是基于很粗糙的信息流。此外,目睹、讨论别人所作决定的结果也未必会帮我们避免糟糕的决策。

追随大流

路是人走出来的,但人多的路径,一定是最好的路径吗?很多人会这么想。从众心理—即随大流,追随潮流和时尚—是人们的普遍行为。行为科学家们就热衷于弄清这一特性的本质。以金融圈为例,随大流是导致股票和资产泡沫化和崩溃的关键原因所在。尽管许多这样的行为很不合理,细究这些现象发生的原因,仍有可能受益匪浅。

信息瀑布

人们多不会自己独立做决定,通过观察他们周围人的行为和结果,跟他们交流,尔后采取了某些行动。这是通过社交学习怎样做决定。做别人做的事在一般人看来是理智的,因为人们断定他们的行为是基于一些很得人看好的信息。当人们忽略自己的信息义无反顾的跟随前人的决定时,这些新人的决定就不能反映他们自己独有的信息。这样的反应不断地发生在一连串的个体身上时,就是信息瀑布。信息瀑布淹没了所有后来者的信息。早期几个先行者有限的信息所形成的决定,被所有人重复。

信息瀑布的问题在于会造成空穴来风这样的结果,因为它并没有汇总这条链中所有参与者的信息。仅观察别人的行为然后单纯根据所见做出同样的决定会导致武断甚或错误的决定。大多情况下,很久以后才会有人真正去探寻一条特定路径背后的逻辑。

信息瀑布造成信息流的中断,后面的人只能得到前期几个先行者很少量的信息,因而可能会导致非常低效率的决定。“我也不知道自己为什么会这样做,大家都这样,应该不会错吧”就很好的概括了这群人的思想。用在当今的中国,路易斯威登包的流行便是一个很好的例子。在有其它同样质量更便宜的包的情况下,为什么路易斯威登包的销量能如此之好?类似的中医理论,坐月子,星座分析,血型决定性格论之流行,都与此有关。

从众心理的合理化

学者们提出了大量关于信息瀑布能够继续发展的原因,尽管信息瀑布多次产生过次优的结果。有趣的是,这些差强人意的结果是在个人衡量得失后、积极选取获得最大个人利益路径的结果。怎样才能让我们的决策避开信息瀑布的陷阱而更有效呢?

在即将发表在《经济理论期刊》上的文章中,曹辉宁、韩冰和David Hirshleifer三位教授在他们的研究模型中让人们对交谈讨论各种决策的得失。 鉴于这些额外的信息,他们发现信息瀑布永久持续的可能性更低。人们对错误的决定耿耿于怀时,有关各种决定的新信息会帮助他们解读任何项目的真正价值。这些信息有时也会推动后继者进行试验。

信息闭塞

然而,社会已习惯于屡次犯同样的错误,因为信息冲击还没有强大到能消除它们。哪怕是观察(交流)受到有限的约束,信息闭塞还是可以轻易实现。由于有信息外部性,信息的整合效率很低。第一,个体看不到后来的决策者调整他们行为后的收益。第二,决策得失相关信息的质量也会影响后面决策者决定的质量。

关键的是“鲜有人迹的道路”缺乏实验和尝试, 人们在熟悉的途径上重复探索,拣到了芝麻,丢了西瓜,这阻碍了社会积极的发展。以科研基金为例,虽然个体研究者能从少量广阔的融资渠道获利更多,但是社会却从更多元化的供资机构获益。因此才能保证在不常有人调查的领域有更多的研究。中国把大量的科研基金集中在少数机构的做法,抑制了独创的研究,造成了平庸学霸后面一大堆更平庸的追随者。

少一点交流

观察决策结果并不见得会减少错误的决策流行发生。决策结果越早为人所知,强化的决策流行就能越早实现。反之,如果一开始就只有少量交流,在“信息流堵塞之前”,后来人就能够整合更多的信息。除此之外,关于决策结果的交流也未必很有效。因为交流常常是“喧闹的”,所以意味着缺少实质的东西。这样,在交流中很难抓住实在的信息。

随着大众媒体和交互式通信技术的兴起,观察别人的决策结果变得愈发容易。表面上看,这为决策者提供了更多的参考信息,但实际上只适用于决策链的开始。对后面的人,作出与前人不同的决定需要有强大的自信和独立精准的信息。对这些人而言,效仿先前的决定是合理的。与鲜有人迹的道路相关的信息流会中断,一旦它们不被认可。

摘要:

鲜有人迹的路:交谈会根除恶性信息瀑布吗?

一连串的个体经常趋同于糟糕的决定,易于赶时髦,尽管他们有前人决定的报酬结果的信息。因而直接或间接的反映了基于行为的信息外部性。与以往的信息瀑布文献不同的是,在这篇文章中,信息瀑布可能会自发消失。并且,从大体上说,永久持续的可能性更小。此外,让人们交流反而可能会降低决策准确性和福利的平均值。

长江商学院甘洁教授论文在《经济学人》里引起反响并重点讨论

Privatisation in China



Capitalism confined



Chinese companies, like companies everywhere, do best when they are privately run. In China, however, the state is never far away



Sep 3rd 2011 |BEIJING

| from the print edition

·



·






IN 1992 two Chinese cities, one just south of Beijing, the other just north of Hong Kong, were in desperate shape even by the standards of a desperately poor country. Their municipally run companies were in danger of bankrupting not only themselves but the cities too. Zhucheng, near Beijing

, was best known as the birthplace of Jiang Qing, Mao Zedong’s despotic, doctrinaire fourth wife, who died in jail in 1991. Two-thirds of its revenues were being eaten by corporate losses. Shunde, a small city in Guangdong, was buried in debt.

Meanwhile, the authorities in Beijing were becoming concerned that the state banking system, already creaking under the weight of bad debt, would be unable to bear even more. With the quiet acquiescence of the central government, Zhucheng and Shunde ignored doctrine, old laws and 40 years of failed policies in search of a better approach.



In a carefully constructed phrase subsequently endorsed, in 1993, by the all-powerful State Council, the two cities engaged ingaizhi, which means “changing the system” and implies the diversification of ownership. Put more simply, in words that even now the Chinese government cannot bring itself to utter, they started to privatise many of their companies. They thus began one of the Chinese state’s first attempts to change its relationship with its enterprises. Jiang Qing would not have approved.



At first Shunde and Zhucheng turned their firms over to employees. In 1997, again before a broader shift in national policy, the two began selling companies directly to existing managements. Shunde, in particular, thrived. Two of the companies that emerged, a maker of bottle caps and a trader of duck feathers, are now among the world’s largest appliance manufacturers, Midea and Galanz. Other factories have spread like wild flowers among what were once rice fields and fish farms.



Early signs of success led to modification of the rules on the ownership of companies. In 1995 the State Council endorsed a policy to “retain the large, release the small”. In 1997 it approved a huge shift of ownership from the central government to municipalities with the explicit goal of expediting privatisations. These changes provided the foundation for the dramatic efforts in the late 1990s of Zhu Rongji, the then prime minister, that are reputed to have remade China’s economy.



The short version is that Mr Zhu closed thousands of companies and broke the “iron rice bowl”, a guarantee of living standards for the masses, in an effort to shake China out of economic lethargy. Between 1995 and 2001 the number of state-owned and state-controlled enterprises fell from 1.2m to 468,000 and the number of jobs in the urban state sector fell by 36m—or from 59% to 32% of total urban employment.



A longer version is that the process involved many more companies and has never ceased, and that the method has changed constantly. As some companies were transformed or closed, others were created, with various forms of state backing. The result has been non-stop experimentation with incentives and structures.



Privatisation remains a thorny issue in a country where private property became a constitutional right only in 2004 and where the right to own productive assets remains unclear. Many vibrant, purely private companies have sprung up despite this uncertainty, but take care to stay out of the limelight. Meanwhile, China’s various experiments with privatisation have created several categories of companies which still have close ties to the state (see table).






A taxonomy of privatisation



The first category comprises the vast banks and transport, energy and telecoms providers that were, and to some extent still are, government ministries. Gordon Orr, chairman of McKinsey’s China business, calls this “version 1.0” of the modern state-controlled company. Although these entities have gained a lot of attention outside China

, they account for perhaps 1% of privatised companies.

The relationship between the state and most other businesses is less direct and more subtle. A second category contains joint ventures between private (often foreign) companies and firms backed by the state. A third consists of companies that are largely in private rather than state ownership, but in which the state remains influential nevertheless. Recently another class has started to emerge, in which the state plays the role of a venture capitalist: local governments invest in or create funds that back companies that they hope will bring both jobs and financial returns.



Start with the behemoths. Most of these huge companies have been turned into vaguely conventional-looking businesses. They have been restructured, recapitalised and rebranded. A minority of their equity has been sold to the public and is traded on the stockmarket. They have recognisable corporate structures with boards of directors, chief executives, chief financial officers and sundry other chiefs; and they publish financial reports with carefully presented accounts and dull letters from the bosses. They are steadily climbing up global rankings, symbols of China’s growing industrial heft.



However, few contend that they are truly private companies. The proportion of shares issued is typically no more than 30%. They receive subsidised loans from state-controlled banks, they are given land cheaply and they usually enjoy a sheltered monopoly or oligopoly. Control by the government is never far away. The state appoints their senior managers—including a Communist Party committee headed by a party secretary.



Often, say insiders, these companies’ doings reflect not so much the explicit orders of the government as managers’ anticipation of what will earn its endorsement. An ambitious manager’s career prospects depend on the party’s Organisation Department, which oversees official appointments—and company bosses frequently move on to senior jobs in the ministries that oversee them. Direct control may have been severed, but rule by inferred command continues.



This model provides the government with continuing control of enterprises critical to the functioning of the economy. In particular, it facilitates the execution of big capital projects such as high-speed railways, steel plants, telecommunications networks and ports.



However, this comes at a cost. There are plenty of opportunities for graft. A close relationship between regulators and operating companies can mean that problems (with safety, as well as economic matters) are overlooked. The lack of commercial orientation frequently means that too many employees throughout the company are unproductive. At the top, there are often cushy, well-paid jobs for the children of the well connected. And the commercial and regulatory privileges of these companies crowd out private alternatives.



At home, it is hard to argue that any of the really big Chinese firms—the banks, the telecoms firms and petrol companies—draw customers because of any special appeal rather than their ubiquity and a lack of competitors. Abroad, despite their size, they are yet to become the global champions that the Chinese government would like them to be, even though the Chinese have sought for many years to learn from foreign corporations. This may be partly because the Chinese giants’ ties to the state limit the extent to which they can imitate foreign multinationals, with senior managers from many countries.



In the late 1990s John Thompson, then head of IBM’s international operations, and some colleagues attending a conference in Beijing were asked to visit Jiang Zemin, the president of China

. Mr Jiang asked the IBMers how such a big company was managed centrally. He also asked how corporations and the American courts dealt with “corruption”—a worry, said Mr Jiang, when Chinese ministries were being privatised. Some months later, Mr Thompson recalls, Mr Jiang asked Lou Gerstner, IBM’s chief executive, if the company would play host to a delegation of newly minted Chinese chief executives and some ministers. The group spent several days at IBM’s executive-education centre in New York state. They then visited other organisations to learn more about how American capitalism was run and regulated.

Yet there was an unbridgeable gap between IBM and China’s behemoths. In most successful global companies, a priority for executives from the home country is to prepare local managers who may one day accede to senior jobs at headquarters. The company becomes international inside as well as out. But because the Chinese giants are still in essence tied to the state, their leaders must remain Chinese.



Evidence of how these entities have performed is muddy because so much of their environment is distorted: for example, given cheap enough money and strong enough protection for their franchise, even corporate sluggards can show good profits and return on equity. However, in 2006 three Chinese academics began a vast study of the performance of privatised companies, summarised in a recent working paper*. Jie Gan of Cheung Kong Graduate School of Business, Yan Guo of Peking University and Chenggang Xu of the University of Hong Kong conclude that the return on assets and profitability per employee for companies that have undergone partial share offerings is indistinguishable from those that were not privatised at all.



One driver better than two



The second category of firms, joint ventures, is also small in number (2% of the academics’ sample). Such ventures involve a bargain between the two sides. Often the private partner is a Western company hoping to gain access to a huge and growing economy. In return the Chinese gain Western know-how. For the Westerners, this involves obvious risks beyond the usual differences of opinion in a joint venture: that they will be pushed aside once the Chinese have acquired their knowledge.



In carmaking, where there have been several prominent joint ventures, a squeeze-out of the Western partner was part of the initial plan, says Michael Dunne, a car-industry consultant, and subtle moves along these lines emerge sporadically. Recently, for example, the government has pushed the Western companies to form “indigenous brand” joint ventures with intellectual-property and export rights. And at the end of 2009, Shanghai Automotive Industry Corporation bought an additional 1% of its venture with General Motors, gaining majority control.



Ms Gan,Mr Guo and Mr Xu find that, overall, joint ventures have yielded similarly lacklustre financial results to the partially privatised behemoths. However, carmaking appears to be an exception. Early ventures involving Peugeot-Citroën and General Motors flopped, but that is now ancient history. More than 20 ventures are currently in existence and although financial information is hard to come by, they seem to be doing well.



This may be because in cars joint ventures have been run more as private companies and less as state-owned entities, when compared with other industries. An explanation, says Mr Dunne, lies in the incentives of the two sides. The senior Chinese representative, inevitably appointed by the government, is rarely a car person. He brings valuable political contacts and is likely to move back to a political job eventually. Meanwhile he has little interest in disrupting a venture that produces profits and jobs. Foreign carmakers are interested chiefly in the success of the company. The two sides’ interests turn out to be aligned, or at least not in conflict.



These same incentives, says Mr Dunne, also explain why the efforts of the Chinese joint-venture partners to develop their own brands have yet to produce much success, despite their access to Western technology, vast resources and political pull. The careers of the Chinese partners are tied to the state, not the car market.



Private management, party influence



The third group, largely in private hands, contains the most successful privatised companies: the half that ended up in the hands of their managers. According to the three academics, management buy-outs have done much better than behemoths, joint ventures or firms privatised through other methods (such as leases or sales to outsiders or employees). This probably has much to do with another finding: that the degree of government control declined most in this group of companies. In only 1% of these firms did the state have a shareholding of more than 20%, against a sample average of 19%. And in only 16% of them did the state have “strong control” of corporate decision-making, against 31% overall. The state has thus forgone ownership in an effort to achieve better results. It does, however, continue to exert influence, notably through party representatives.



Consider the state’s involvement with the three Chinese car companies that have done most to build their brands: BYD, Chery and Geely. They are still under the state’s wing, being thought to receive ample financial help from the provinces where they operate (though much the same could be said of many carmakers in the West). Their leaders surely would not last if the state disapproved of them. Yet they are not state-controlled, unlike the behemoths or the Chinese partners in joint ventures. The bosses are not political appointees but charismatic businessmen in pursuit of commercial goals.



There are similar ventures in other industries: ZTE and Huawei, two telecoms-equipment giants; Lenovo, a maker of PCs, in which the Chinese Academy

of Sciences has a large minority stake; and TCL, an electronics firm. The number of companies in this group continues to swell, even if they are less well known than these. As a rule, they are in industries designated as “strategic”—notably anything to do with energy, be it wind, solar or stored—and can also be found in medical equipment, drugs and technology. Such companies benefit from protection against foreign encroachment, research-and-development subsidies, and subsidised purchases from state customers. Someone involved with a foreign health-care company says that buyers connected with the Chinese state demand such generous terms—with payment delayed for up to a year—that only domestic providers, backed by accommodating credit from state banks, can bid for orders.




The fostering of successful private companies becomes particularly attractive in markets in which state entities have plainly been found wanting. The clearest example is the internet, in which China’s state-controlled news providers and broadcasters have the resources and content to succeed but have failed to create much of a buzz. From private internet companies, which were never state-owned, the buzz is deafening. Their managers have often trained abroad. Competition is rampant—although foreign companies face impediments—and quick wits are essential for success. Employees often receive a significant amount of compensation in that most Western of forms: shares or share options. Many of these companies, because of their listings in overseas markets, or backing from foreign investors, could technically be considered foreign, a cause of some scathing criticism in China

.

Yet even these companies depend on the good graces of the state. The Western firms that some of them imitated find obstacles in their way in China. Baidu

, China’s leading internet-search company, profited hugely in the past from being a conduit for pirated Western entertainment. Alibaba, a facilitator of e-commerce, has used Chinese ownership laws to take a large slice of Yahoo!’s valuable stake in its electronic-payment company, Alipay. Relations with officialdom are not always smooth. Beijing’s Communist Party chief recently warned Sina, a social-media firm, that it was too slow to delete remarks that displeased the party. And recent programmes on CCTV, the state broadcaster, have criticised Baidu’s business methods.

Back to the cities



The success of this third group of companies has encouraged the development of the fourth. Officials in cities and provinces have created hundreds of municipally backed funds to invest in promising ventures. According to Z-Ben Advisors, a research and consulting firm, the biggest of these, CDB Capital, a private-equity fund established only in 2009, has raised 40 billion yuan ($6.3 billion) and has a target of 60 billion yuan.



Some of these official investors have brought in foreign partners, including big private-equity firms such as Blackstone, Carlyle and TPG. Infinity Group, an Israeli venture-capital firm, has 12 funds, ten of which have direct ties to different Chinese cities. Its earliest effort, founded in 2004 with money from the Israeli and Chinese governments and private sources, has had much success creating companies combining Chinese manufacturing and Israeli technology.



In theory, making the state into a purely financial investor rather than an operating partner, as in Shunde and Zhucheng 19 years ago, should be beneficial: entrepreneurs, not bureaucrats, run the business. Practice is rarely so neat. Cities back companies that provide local jobs. That affects acquisitions and disposals, where factories are built and where research takes place. Worse, China’s private-equity industry has become another lucrative billet for the children of powerful officials.



It is also troubling that little is disclosed about the operations and returns of these public funds. Many may be managed cleverly and provide money for municipalities and jobs for their citizens; others, though, may turn out to be financial black holes. Equally troubling, they receive favourable attention from local governments, to the disadvantage of China’s most dynamic sector, its truly private companies.



Taken collectively, these iterations of state engagement reflect how China’s government has not only held on to economic control but found subtle ways to extend it. At the very least, they constitute an important series of large-scale economic experiments with implications for China

’s economy and, because of China’s size, the world’s too. Some may see in this a path to follow. China has come far since the trials in Shunde and Zhucheng, but the state has always controlled the itinerary.
