We find significant variation in the prior stock returns of firms that dismiss their CEOs between 1996 and 2008. 49% of firms that dismiss their CEOs do so in the absence of negative industry-adjusted stock returns prior to dismissal (37% dismiss in the absence of negative raw returns). We find evidence for two reasons why boards may dismiss CEOs early, i.e., in the absence of significant poor prior stock performance. First, we find that early dismissals are more likely to be associated with corporate scandals, suggesting that CEOs that are found to engage in unethical or illegal activities are dismissed although their actions may not have a significant adverse impact on firm value. Second, we find support for the argument that early dismissals are proactive actions by boards to dismiss low ability CEOs. We find that firms with more equity-based compensation for directors and higher independent director ownership are more likely to dismiss their CEOs early. Boards with strong incentives are more likely to be proactive and act on their private information about the CEO than boards with poor incentives. Early dismissal firms experience a short-lived decline in operating performance around the date of CEO dismissal, and their operating performance recovers immediately after the CEO is replaced. On the other hand, the operating performance of late dismissal firms declines significantly prior to dismissal and improves substantially after dismissal. We also find that CEOs that are dismissed early are not more likely to find new CEO positions than CEOs that are dismissed late, supporting the idea that early dismissal CEOs may not have different ability than late dismissal CEOs.  相似文献

This paper extends the work of accounting educators and researchers who have sought to develop and implement effective ethics interventions in the accounting curriculum. Its purpose is to assess the influence of ethics interventions, integrated into a one-semester introductory auditing course at both the undergraduate and graduate level, on the moral development and ethical behavior of accounting students. Ethics interventions were based on the review and discussion of ethics cases following a well known pedagogical framework over the first 10 weeks of one academic semester. The effectiveness of these interventions was tested two ways. First, using the Defining Issues Test (DIT) and a pre/post-test research design, the moral development of accounting seniors and graduate students in four separate auditing classes was assessed. Second, students' unethical behavior, defined as excessive “free-riding” on an economic-choice experiment based on the Prisoners' Dilemma, was observed by the researcher. In summary, results of this study show that ethics interventions did not cause accounting students' level of ethical reasoning to develop (increase) and did not curtail students' free-riding behavior. Findings also provide evidence of an association between ethical reasoning and students' economic choices, where students with relatively low and high levels of ethical reasoning were most likely to engage in free-riding. The implications of these findings are discussed in the last section of the paper.  相似文献

We study the link between beta predictability and the price of risk. An investor who desires exposure to a certain risk factor needs to predict what next period’s beta will be. We use a simple model to show that an ambiguity averse agent’s demand is lower when betas are hard to predict, leading to a reduction in risk premiums. We test the implications for downside betas and VIX betas. We find that they have economically and statistically small prices of risk once we account for the fact that an investor cannot observe ex-post realized betas when determining asset demand.  相似文献

There is overwhelming empirical evidence on the existence of country and industry momentum effects. This line of research suggests that investors who buy country and industry portfolios with relatively high past returns and sell countries and industries with relatively low past returns will earn positive risk-adjusted returns. These studies focus on country and industry indexes that cannot be traded directly by investors. This raises the question of whether country and industry momentum effects really can be exploited by investors or whether they are illusionary in nature because they exist only on non-tradable assets. We analyze the profitability of country and industry momentum strategies using actual price data on exchange traded funds (ETFs). We find that over the sample periods during which these ETFs were traded, an investor would have been able to exploit country and industry momentum strategies with an excess return of about 5 % per annum. These returns cannot be explained by unconditional exposures to the Fama–French factors. The daily average bid-ask spreads on ETFs are substantially below the implied break-even transaction cost levels. Hence, we conclude that investors who are not willing or able to trade individual stocks may use ETFs to benefit from momentum effects in country and industry portfolios.  相似文献

In a seminal study, Elton and Gruber (1970) argue that ex-dividend day pricing can be used to infer marginal tax rates of shareholders. We examine ex-dividend day pricing for individual firms and ask whether their CFOs could use the history of a firm's ex-dividend price-drop ratios to infer reasonable estimates of shareholders’ marginal tax rates. We use TAQ data for 1,124 US firms that have at least 30 ex-dividend days during the period August 1993 to October 2012. Our results show that ex-dividend day pricing is so noisy as to prohibit sensible estimates of shareholders’ marginal tax rates.  相似文献

Financial markets, such as the global foreign exchange (FX) market, often exhibit trending behaviour. Within such trends, the market level oscillates with changes in market consensus. Continued oscillations of this type result in the formation of wave patterns within the underlying trend known as channels, which are used by technical analysts as trade entry signals. A sample space of such channels has been constructed from a set of US dollar/British pound Spot FX tick data from 1989–1997 using pattern recognition algorithms and the profitability of trading using such patterns has been estimated. A number of attributes of the resulting collection of channels has been subjected to statistical analysis with the aim of classifying patterns that can be traded profitably using a number of simple trading rules. Results of this analysis show that there exist statistically significant links between the channels' attributes and profitability.  相似文献

Under economies with hyperbolic preferences, vast research has investigated welfare‐improving tax policies to resolve capital misallocation issues. In this paper, we suggests an alternative channel to overcome a form of this issue associated with consumer's present bias—optimism, as defined by overexpectation of future productivity. We show that even though optimism negatively impacts consumers under normal circumstances, a moderate level of it can be beneficial when consumers have hyperbolic preferences. On the other hand, pessimism always negatively impacts consumer welfare. A steady‐state analysis shows that the quantitative impact of optimism on welfare can be sizable.  相似文献

We investigate whether firms’ corporate social performance (CSP) ratings impact their performance (cost of capital) and risk. Using a proprietary CSP ratings database, we find no difference in the risk-adjusted performance of UK firms with high and low CSP ratings. Additionally, the firms do not differ in their amount of idiosyncratic risk. We find some evidence of high-ranked firms being larger. The empirical evidence therefore indicates that investors and managers are able to implement a CSP investment or business strategy without incurring any significant financial cost (or benefit) in terms of risk or return.  相似文献

In 1976, Genentech, the first biotechnology company, was founded by a young venture capitalist and a university professor to exploit recombinant DNA technology. Thirty years and more than 300 billion dollars in investments later, only a handful of biotech firms have matched Genentech's success or even shown a profit. No avalanche of new drugs has hit the market, and the long-awaited breakthrough in R&D productivity has yet to materialize. This disappointing performance raises a question: Can organizations motivated by the need to make profits and please shareholders successfully conduct basic scientific research as a core activity? The question has largely been ignored, despite intense debate over whether business's invasion of basic science-long the domain of universities and nonprofit research institutions- is limiting access to discoveries, thereby slowing advances in science. Biotech has not lived up to its promise, says the author, because its anatomy, which has worked well in other high-tech sectors, can't handle the fundamental challenges facing drug R&D: profound, persistent uncertainty and high risks rooted in the limited knowledge of human biology; the need for the diverse disciplines involved in drug discovery to work together in an integrated fashion; and barriers to learning, including tacit knowledge and murky intellectual property rights, which can slow the pace of scientific advance. A more suitable anatomy would include increased vertical integration; a smaller number of closer, longer collaborations; an emphasis by universities on sharing rather than patenting scientific discoveries; more cross-disciplinary academic research; and more federal and private funding for translational research, which bridges basic and applied science. With such modifications, science can be a business.  相似文献

The standard modeling practice in corporate finance has been to assume a linear tax schedule. This paper extends the structural contingent-claim model of corporate finance to incorporate a more realistic convex tax schedule. It is shown that tax convexity raises the optimal default boundary and thus increases the likelihood of default, and also reduces the optimal leverage ratio. While the former effect seems insignificant in general, the effect of tax convexity on the optimal leverage ratio can be quantitatively significant. We conclude that tax convexity should not be ignored in corporate financing decisions, and theoretical models should use a convex tax schedule instead of a linear one. Thus, the short answer to the question in the title is “No”.  相似文献

Today a company is not considered environmentalist unless it moves beyond mere compliance with government regulations to behavior its competitors, and even customers, do not expect. How should it set its agenda? Author Art Kleiner proposes that, to be green, a company must ask three questions: What products should we bring to market? How much disclosure of pollution information should we support? And how can we reduce waste at its source? These questions can't be answered, Kleiner says, unless managers insist on sustainable growth. In this sense, a big investment in environmentalism is like a big one in R&D--both presuppose patient capital and managerial maturity. What are green products? Kleiner cautions against giving in to misinformed public opinion--as McDonald's did in giving up its styrene "clamshells," which were more recyclable than the composite papers it switched to. Rather, companies should rely on literature that analyzes the product life cycle. As for public disclosure, the benefits may be unexpected. Federal legislation requiring companies to report the emission of potentially hazardous waste to a central data bank has not made environmentalists attack them. Rather, it has forced companies to learn what chemicals they inadvertently produce and how much--knowledge that helps them improve production processes. Sharing it helps ecological researchers study the combined effects of plant emissions. As for pollution prevention, Kleiner notes the analogy to quality and observes that it is better to design harmful waste products out of the system than catch them at the end of the line.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

Using daily data for a select set of four Asian exchange rates, namely the Hong Kong dollar, the Singapore dollar, the Taiwan dollar and the Thailand baht, from October 1985 to October 2002, we apply principal components analysis and the O-GARCH model to describe the evolution and persistence in the correlations over time. We also estimate 2-, 3- and 4-variable multivariate GARCH models, without imposing the assumption of constant correlations, to investigate volatility interaction amongst the currencies. To allow for fat tails in the distributions of exchange rate changes, we use the multivariate student-t distribution in maximising our log-likelihood functions. Our results indicate the possibility of designing an Asian exchange rate system involving a number of the region's currencies.  相似文献

In this study, we examined the effectiveness of central bank communications during times of significant adverse shocks. Specifically, we examined how the National Bank of Ukraine (NBU) regulated foreign exchange (FX) markets during the Russo-Ukrainian War in 2022. Data collected from both the black and authorized FX markets suggested that the content of the NBU's announcements significantly impacted FX market agents. Announcements aimed at maintaining a fixed (floating) FX rate prompted an increase (decrease) in the black market premium in cash transactions. Moreover, the NBU's announcements influenced the sale side of foreign currency more than any other aspect, an area where the black market FX traders held near monopolistic power.  相似文献

Financial systems all over the world have grown dramatically over recent decades. But is more finance necessarily better? And what concept of financial system – a focus on its size, including both intermediation and other auxiliary “non-intermediation” activities, or a focus on traditional intermediation activity – is relevant for its impact on real sector outcomes? This paper assesses the relationship between the size of the financial system and intermediation, on the one hand, and GDP per capita growth and growth volatility, on the other hand. Based on a sample of 77 countries for the period 1980–2007, we find that intermediation activities increase growth and reduce volatility in the long run. An expansion of the financial sectors along other dimensions has no long-run effect on real sector outcomes. Over shorter time horizons a large financial sector stimulates growth at the cost of higher volatility in high-income countries. Intermediation activities stabilize the economy in the medium run especially in low-income countries. As this is an initial exploration of the link between financial system indicators and growth and volatility, we focus on OLS regressions, leaving issues of endogeneity and omitted variable biases for future research.  相似文献
