One aspect in which non‐financial corporations (NFCs) are said to be financialized is that they have been increasingly engaged in financial accumulation from which they derive a growing proportion of financial income. This is what we call the financial turn of accumulation hypothesis. In this article, we show that the evidence used to sustain it, in the U.S. setting, has to be reconsidered. Our findings show that, contrary to the financial turn of accumulation hypothesis, financial income averages 2.5% of NFCs’ total income since the 1980s, oscillating since the beginnings of the 1990s until 2005 and then declining. In terms of assets, some of the alleged financial assets might actually reflect other activities in which NFCs have been increasingly engaged, such as tax avoidance, internationalization of production, activities refocusing and M&As.  相似文献

In a conversation held in June 2016 between Nobel laureate Eugene Fama of the University of Chicago and Joel Stern, chairman and CEO of Stern Value Management, Professor Fama revisited some of the landmarks of “modern finance,” a movement that was launched in the early 1960s at Chicago and other leading business schools, and that gave rise to Efficient Markets Theory, the Modigliani‐Miller “irrelevance” propositions, and the Capital Asset Pricing Model. These concepts and models are still taught at prestigious business schools, whose graduates continue to make use of them in corporations and investment firms throughout the world. But while acknowledging the staying power of “modern finance,” Fama also notes that, even after a half‐century of research and refinements, most asset‐pricing models have failed empirically. Estimating something as apparently simple as the cost of capital remains fraught with difficulty. He dismisses betas for individual stocks as “garbage,” and even industry betas are said to be unstable, “too dynamic through time.” What's more, the wide range of estimates for the market risk premium—anywhere from 2% to 10%—casts doubt on their reliability and practical usefulness. And as if to reaffirm the fundamental insight of the M&M “irrelevance” propositions—namely, that what companies do with the right‐hand sides of their balance sheets “doesn't matter”—Fama observes that “we still have no real resolution on the key questions of debt and taxes, or dividends and taxes.” But if he has reservations about much of modern finance, Professor Fama is even more skeptical about subfields now in vogue such as behavioral finance, which he describes as “mostly just dredging for anomalies,” with no underlying theory and no testable predictions. Although he does not dispute that a number of well‐documented traits from cognitive psychology show up in individual behavior, Fama says that behavioral economists have thus far failed to come up with a testable theory that links cognitive psychology to market prices. And he continues to defend the concept of “efficient markets” with which his name has long been closely associated, while noting that empirically based asset pricing models such as his (with Ken French) “three‐factor” CAPM have produced much better results than the standard CAPM.  相似文献

This article shows how to construct an optimal capital structure for a private firm. Since the agents who supply the firm’s capital are risk averse, they diversify by holding both debt and equity. This can mitigate, or even eliminate, the classical risk shifting problem. There is a wealth effect since the optimal capital structure, which can involve multiple types of debt, depends on the amount of wealth that each agent contributes to the firm. However, it is shown that the agents’ equity holdings do not depend on the contributed amounts of wealth. Thus the model can produce a wedge between ownership rights and equity cashflow rights. These features are illustrated in a firm with three agents.  相似文献

This paper examines the uncertain information hypothesis on one major index and its corresponding exchange-traded fund: the S&P 500 Index and SPDRs in the pre-SPDRs (01/63–12/93) and post-SPDRs (01/94–12/03) periods. Two strategies are used to measure the economic significance of the uncertain information hypothesis. Overall, we present evidence confirming the uncertain information hypothesis in the post-SPDRs period. However, we fail to convert the statistically significant gains observed into economic gains under a conservative approach. In addition, the degree of difference in the volatilities of the 5-day post-event returns (in both the S&P 500 and the SPDR) among the three subgroups diminishes in the post-SPDR period. Hence, we conclude that the market is in fact short-term efficient in a more realistic setting.  相似文献

Enhancing airport runway safety is a difficult problem because runway accidents are rare events. Nonetheless, investments are being directed at improving safety for US airport ground traffic control systems. This paper shows that under these circumstances it is difficult to assess and measure the added safety offered by new replacement systems. We develop a framework for introducing and sequencing system improvements to provide greater assurances in enhancing safety. This framework shows how a new method can first be introduced as a secondary system, to test and verify its efficacy prior to its adoption as a primary system.  相似文献

This paper explores whether DICTION text analysis software reveals distinctive language markers of a verbal tone of hubris in annual letters to shareholders signed by CEOs of major companies. We analyze 193 letters to shareholders, comprising about 368,000 words, focusing initially on 23 letters signed by CEOs who are alleged to be hubristic: Browne (BP), Goodwin (Royal Bank of Scotland), and Murdoch (News). Their language use is statistically significantly high in terms of the DICTION master variable, REALISM. Based on further analysis, we contend that language high in REALISM is not a distinctive marker of hubris but is likely to be a genre effect that is common in CEO letters to shareholders. We draw attention to the restricted capacity of DICTION to capture subtlety of language in CEO letters to shareholders.  相似文献

This paper develops a dynamic duopolistic model of advertising and price competition. Advertising accumulates a stock of goodwill which enters directly into the demand functions and both the cooperative and predatory effects of advertising are considered. It is shown that firms invest more in advertising the higher the degree of cooperativeness of advertising and some comparative static results are provided. In the second, empirical part of the article, estimations of the demand equations are presented using data from the German automobile industry. The main conclusion drawn is that advertising plays an important role in this market and has a predatory nature.  相似文献

Public trust in government and nongovernment organizations is essential to the public’s willingness to donate and to support those organizations. We measure public trust in disaster aid using people’s perception of these organizations’ effectiveness in delivering aid relief to the victims of two recent major earthquakes in China. Based on the survey data collected in 2013 from about 2100 residents in Hong Kong, we document the vulnerability of these residents’ trust perceptions in aid delivery. We find that the sharp decline in trust perception is highly negatively correlated with their perception of corruption of local governments in China.  相似文献
