Economics, History, and Causation 经济学、历史和因果关系

R. Morck, B. Yeung
Economics and history both strive to understand causation: economics by using instrumental variables econometrics, and history by weighing the plausibility of alternative narratives. Instrumental variables can lose value with repeated use because of an econometric tragedy of the commons: each successful use of an instrument creates an additional latent variable problem for all other uses of that instrument. Economists should therefore consider historians' approach to inferring causality from detailed context, the plausibility of alternative narratives, external consistency, and recognition that free will makes human decisions intrinsically exogenous.
经济学和历史学都努力理解因果关系:经济学通过使用工具变量计量经济学,而历史学通过权衡不同叙述的合理性。由于计量经济学的公地悲剧,工具变量可能会随着重复使用而失去价值:一种工具的每次成功使用都会为该工具的所有其他使用带来额外的潜在变量问题。因此,经济学家应该考虑历史学家从详细的背景中推断因果关系的方法,其他叙述的合理性,外部一致性,以及自由意志使人类决策本质上是外生的认识。

The Riddle of the Great Pyramids 大金字塔之谜
Pub Date : 2009-04-01 DOI: 10.3386/W14858
R. Morck
Large pyramidal family controlled business groups are the predominant form of business organization outside America, Britain, Germany, and Japan. Large pyramidal groups comprising dozens, even hundreds, or listed and unlisted firms place the governance of large swathes of many countries' big business sectors in the hands of a few of their wealthiest families. These structures plausibly substitute for weak market institutions in economies undergoing rapid early-stage industrialization. They may also substitute for weak governments in coordinating Big Push growth programs to establish numerous interdependent simultaneously. However, no such role is evident in developed or in slowly growing developing economies, where such structures appear prone to agency problems and political rent-seeking. If sufficiently large, they may also add to economy volatility by rendering the risk of misgovernance systematic, rather than firm-specific.
除了美国、英国、德国和日本以外,大型金字塔家族控制的商业集团是主要的商业组织形式。由数十家,甚至数百家上市或未上市公司组成的大型金字塔集团,将许多国家大型商业部门的大片管理权掌握在少数最富有的家族手中。这些结构似乎可以替代处于快速早期工业化阶段的经济体中脆弱的市场制度。它们还可以代替软弱的政府协调“大推动”增长计划,同时建立众多相互依存的项目。然而,在发达国家或增长缓慢的发展中国家,这种作用并不明显,在这些国家,这种结构似乎容易出现代理问题和政治寻租。如果规模足够大,它们还可能使治理不当的风险成为系统性的,而不是企业特有的,从而加剧经济波动。

Review of China's Financial System and Initiatives for the Future 中国金融体系回顾及未来举措
Pub Date : 2008-07-28 DOI: 10.2139/ssrn.1185877
Franklin Allen, Jun Qian, Meijun Qian, Mengxin Zhao
We provide a comprehensive review of China's financial system, and explore directions of future development. First, the current financial system is dominated by a large banking sector. In recent years banks have made considerable progress in reducing the amount of non-performing loans and improving their efficiency. It is important that these efforts are continued. Second, the role of the stock market in allocating resources in the economy has been limited and ineffective. Further development of China's stock market and other financial markets is the most important task in the long-term. Third, the most successful part of the financial system, in terms of supporting the growth of the overall economy, is a non-standard sector that consists of alternative financing channels, governance mechanisms, and institutions. This sector should coexist with banks and markets in the future in order to continue to support the growth of the Hybrid Sector (non-state, non-listed firms). Finally, in order to sustain stable economic growth, China should aim to prevent and halt damaging financial crises, including a banking sector crisis, a real estate or stock market crash, and a twin crisis in the currency market and banking sector.
我们对中国金融体系进行了全面的回顾,并探讨了未来的发展方向。首先,目前的金融体系由庞大的银行业主导。近年来,银行在减少不良贷款数量和提高效率方面取得了相当大的进展。这些努力必须继续下去。第二,股票市场在经济中配置资源的作用有限且无效。进一步发展中国的股票市场和其他金融市场是长期最重要的任务。第三,就支持整体经济增长而言,金融体系最成功的部分是一个由替代融资渠道、治理机制和机构组成的非标准部门。未来,这个部门应该与银行和市场共存,以继续支持混合部门(非国有、非上市公司)的增长。最后,为了维持稳定的经济增长,中国应该致力于防止和制止破坏性的金融危机,包括银行业危机、房地产或股市崩盘,以及货币市场和银行业的双重危机。

Shareholder Value Maximization: What Managers Say and What They Do 股东价值最大化:管理者说什么和做什么
Pub Date : 2003-08-14 DOI: 10.2139/ssrn.337140
Petra Joerg, Claudio Loderer, Lukáš Roth
This paper examines whether Swiss firms maximize shareholder value. To find out, we survey the goals of 313 listed and unlisted firms. We then examine whether managers' decisions are consistent with their goals and analyze whether performance corresponds to intentions. Our results show that most managers pursue conflicting targets. Moreover, they mention maximization of shareholder value only about half of the time. And when they do, it is often because share prices have fallen. Shareholder-value maximizing managers sometimes rely on inconsistent investment criteria. We also find that share-price performance is marginally better when managers claim to maximize shareholder value, particularly after a stock price decline.
本文考察了瑞士公司是否实现了股东价值最大化。为了找到答案,我们调查了313家上市和非上市公司的目标。然后,我们检查管理者的决策是否与他们的目标一致,并分析绩效是否与意图相符。我们的研究结果表明,大多数管理者追求的是相互矛盾的目标。此外,他们只有大约一半的时间提到股东价值最大化。当他们这样做时,通常是因为股价下跌。追求股东价值最大化的管理者有时依赖于不一致的投资标准。我们还发现,当管理者声称要实现股东价值最大化时,股价表现略微更好,尤其是在股价下跌之后。

Characteristics of Hostile and Friendly Takeover Targets 敌意收购和友好收购目标的特征
Pub Date : 1987-06-01 DOI: 10.3386/W2295
R. Morck, Andrei Shleifer, Robert W. Vishny
Compared to an average Fortune 500 firm, a target of a hostile takeover is smaller, older, has a lower Tobin's Q, invests less of its income, and is growing more slowly. The low Q seems to be an industry-specific rather than a firm-specific effect. In addition, a hostile target is less likely to be run by a member of the founding family, and has lower officer ownership, than the average firm. In contrast, a target of a friendly acquisitions is smaller and younger than an average Fortune 500 firm, and has comparable Tobin's Qs and most other financial characteristics. Friendly targets are more likely to be run by a member of the founding family, and have higher officer ownership, than the average firm. The decision of a CEO with a large stake and/or with a relationship to a founder to retire often precipitates a friendly acquisition. These results suggest that the motive for a takeover often determines its mood. Thus disciplinary takeovers are more often hostile, and synergistic ones are more often friendly.
与《财富》500强公司的平均规模相比,敌意收购的目标规模更小、历史更悠久、托宾Q值更低、投资收入更少、增长更慢。低Q似乎是行业特有的效应,而不是公司特有的效应。此外,与一般公司相比,敌意目标不太可能由创始家族成员经营,高管持股比例也较低。相比之下,友好收购的目标比财富500强公司的平均规模更小,成立时间也更短,并且具有可与托宾Qs和大多数其他财务特征相比较的特征。与一般公司相比,友好的目标公司更有可能由创始家族成员经营,并且拥有更高的高管所有权。拥有大量股份和/或与创始人有关系的首席执行官决定退休,往往会促成友好收购。这些结果表明,收购的动机往往决定其情绪。因此,纪律收购往往是敌对的,而协同收购往往是友好的。
