摘要：We provide a formal treatment of both static and dynamic portfolio choice using the Disappointment Aversion preferences of Gul (1991. Econometrica 59(3), 667-686), which imply asymmetric aversion to gains versus losses. Our dynamic formulation nests the standard CRRA asset allocation problem as a special case. Using realistic data generating processes, we find reasonable equity portfolio allocations for disappointment averse investors with utility functions exhibiting low curvature. Moderate v...

摘要：We study the effect of a sovereign credit rating change of one country on the sovereign credit spreads of other countries from 1991 to 2000. We find evidence of spillover effects; that is, a ratings change in one country has a significant effect on sovereign credit spreads of other countries. This effect is asymmetric: positive ratings events abroad have no discernable impact on sovereign spreads, whereas negative ratings events are associated with an increase in spreads. On average, a one-not...

摘要：We develop an equilibrium model to understand how the efficiency of capital allocation depends on outside investor protection and the external financing needs of firms. We show that when capital allocation is constrained by poor investor protection, an increase in firms' external financing needs may improve allocative efficiency by fostering the reallocation of capital from low to high productivity projects. We also find novel empirical support for this prediction. (C) 2004 Elsevier B.V. All r...

摘要：The U.S. book-building method has become increasingly popular for initial public offerings (IPOs) worldwide over the last decade, whereas sealed-bid IPO auctions have been abandoned in nearly all of the many countries in which they have been tried. I model book building, discriminatory auctions, and uniform price auctions in an environment in which the number of investors and the accuracy of investors' information are endogenous. Book building lets underwriters manage investor access to shares...

摘要：This paper studies the mutual fund industry in 56 countries and examines where this financial innovation has flourished. The fund industry is larger in countries with stronger rules, laws, and regulations, and specifically where mutual fund investors' rights are better protected. The industry is also larger in countries with wealthier and more educated populations, where the industry is older, trading costs are lower and in which defined contribution pension plans are more prevalent. The indus...

摘要：We investigate a consumption-based present-value relation that is a function of future dividend growth and find that changing forecasts of dividend growth are an important feature of the post-war U.S. stock market, despite the failure of the dividend-price ratio to uncover such variation. In addition, dividend forecasts are found to covary with changing forecasts of excess stock returns over business cycle frequencies. This covariation is important because positively correlated fluctuations in...

摘要：Regulation Fair Disclosure, implemented on October 23, 2000, prohibits U.S. public companies from making selective, nonpublic disclosures to favored investment professionals. Regulation Fair Disclosure has a number of exclusions, however, including disclosure of nonpublic information to credit rating agencies. As a result, credit analysts at rating agencies have access to confidential information that is no longer made available to equity analysts, potentially increasing the information conten...

摘要：Recent evidence indicates irrational behavior among retail investors. They hold onto losses and sell winners in a manner consistent with the disposition effect. Market professionals often use the term discipline to indicate trading strategies that minimize potential behavioral influences. We investigate the nature of trading discipline and whether professional traders are able to avoid the costly irrational behaviors found in retail populations. The full-time traders in our sample hold onto lo...

摘要：We study the dynamics of IPOs by examining the tradeoff between an entrepreneur's private benefits, which are lost whenever the firm is publicly traded, and the gains from diversification. We characterize the timing dimension of the decision to go public and its impact on firm value and the evolution of firm risk over time. By endogenizing the timing of the decision to go public, we explain the clustering of IPOs and buyouts in time, the industry concentration of IPO waves, the high incidence ...

摘要：I analyze market-order execution quality using order-based data reported in accordance with Securities and Exchange Commission Rule 11Acl-5. These data facilitate a comprehensive investigation of multiple dimensions of execution quality, including measures of costs and speed, for large samples of common stocks on Nasdaq and the NYSE. The evidence is consistent with competitive equity markets. Overall execution costs on Nasdaq exceed those on the NYSE, but orders execute faster. This relationsh...
