We characterize the conditions under which efficient portfolios put small weights on individual assets. These conditions bound mean returns with measures of average absolute covariability between assets. The bounds clarify the relationship between linear asset pricing models and well-diversified efficient portfolios. We argue that the extreme weightings in sample efficient portfolios are due to the dominance of a single factor in equity returns. This makes it easy to diversify on subsets to reduce residual risk, while weighting the subsets to reduce factor risk simultaneously. The latter involves taking extreme positions. This behavior seems unlikely to be attributable to sampling error. 相似文献

When the Congress barred the importation of slaves into the United States in 1808, it left the internal slave trade intact. The trade took on a new importance as the slave states of the Old South saw their agricultural economies shift to a point that holding large numbers of slaves became too expensive. During this time, the large agricultural concerns shifted to the New South, where cotton and sugar plantations needed the cheap labour provided by the institution of slavery. As this transition intensified, Richmond, Virginia, became a central slave market that facilitated the interstate slave trade as Old South planters chose the course of selling slaves as a valuable commodity rather than the course of manumission. The records of two businesses—Dickinson & Hill and Hector Davis & Company—which plied the slave trade in the Richmond market, have survived into the twenty-first century. These records revealed a primitive, yet sophisticated, process to account for the consignment, purchase, and sales of human merchandise in this haunting story of the 'business of suffering'. 相似文献

This study examines whether market participants react to the announcements of corporate governance ranking exercises. As a regulatory innovation, the Financial Supervisory Commission in Taiwan initiated and administered two ranking exercises, one in 2015 and the other in 2016, on all publicly listed companies. Adopting anchoring-and-adjustment theory, the study predicts that market participants will react strongly to the second announcement if the ranking obtained in the second exercise turns out to be better than the ranking in the first round. Employing an event study methodology, the study shows that market participants react positively and significantly to firms ranked in the top 50% in the second corporate governance exercise. Their reactions to the announcement are even stronger among those that did not list in the top 20% in the first exercise, but made it into the top 50% in the second one. Overall, our analyses support that anchoring-and-adjustment theory effectively explains market participants’ behaviour. Since the monitoring of the board of directors and investors may not effectively mitigate the potential moral hazard committed by family owners/executives, our empirical evidence demonstrates that a ranking exercise probably can be employed to supplement routine corporate governance disclosures made in annual reports, in order to strengthen the check-and-balance mechanism and reduce the risk of principal–principal conflicts. In conclusion, we discuss the implications of the research findings and propose directions for future studies. 相似文献

This paper describes situations in which tax liabilities assume the form of a negative position in a call option. This structure motivates an examination of the investment decisions of taxed corporations in the presence of risk. It is shown that the structure of the tax liability creates an incentive to underinvest in more risky projects and an incentive for conglomerate merger. These effects are then evaluated in the presence of conflicts of interest between stockholders and bondholders, and under alternative assumptions about the tax code, and about the timing of investment and financing decisions. 相似文献

We use market data on corporate bonds and equities to measure the value of U.S. corporate assets and their payouts to investors. In contrast to equity dividends, total corporate payouts are highly volatile, turn negative when corporations raise capital, and are acyclical. At the same time, corporate asset returns are similar to returns on equity, and both are exposed to fluctuations in economic growth. To reconcile this evidence, we argue that acyclical but volatile net repurchases mask the exposure of total payouts' cash components to economic growth risks. We develop an asset pricing framework to quantitatively illustrate this economic channel. 相似文献

This paper analyzes the relationship between Australian stock returns and inflation over the period 1965-79. The effects of inflation in a ‘rational investor’ valuation framework are discussed. Empirical tests suggest that nominal stock returns and inflation are related in a significantly negative fashion, implying that stocks have been extremely poor inflationary hedges for the investor over the period. In addition, Granger-Sims tests of causality indicate a mainly unidirectional relationship between inflation and stock returns, with price level charges leading the equity index in time. 相似文献
