摘要：This paper documents that hedge funds did not exert a correcting force on stock prices during the technology bubble. Instead, they were heavily invested in technology stocks. This does not seem to be the result of unawareness of the bubble: Hedge funds captured the upturn, but, by reducing their positions in stocks that were about to decline, avoided much of the downturn. Our findings question the efficient markets notion that rational speculators always stabilize prices. They are consistent w...

摘要：We examine whether the market interprets changes in dividends as a signal about the persistence of past earnings changes. Prior to observing this signal, investors may believe that past earnings changes are not necessarily indicative of future earnings levels. We empirically investigate whether a change in dividends alters investors' assessments about the valuation implications of past earnings. Results confirm the hypothesis that changes in dividends cause investors to revise their expectatio...

摘要：While many firms grant executive stock options that can be repriced, other firms systematically restrict or prohibit repricing. This article investigates the determinants of firms' repricing policies and the consequences of such policies for executive turnover and retention. Firms that have better internal governance, that use more powerful stock-based incentives, or that face less shareholder scrutiny are more likely to maintain repricing flexibility. Firms that restrict repricing are more vu...

摘要：We test whether momentum strategies remain profitable after considering market frictions induced by trading. Intraday data are used to estimate alternative measures of proportional and non-proportional (price impact) trading costs. The price impact models imply that abnormal returns to portfolio strategies decline with portfolio size. We calculate break-even fund sizes that lead to zero abnormal returns. In addition to equal- and value-weighted momentum strategies, we derive a liquidity-weight...

摘要：This paper investigates the importance of idiosyncratic consumption risk for the cross-sectional variation in asset returns. We find that besides the rate of aggregate consumption growth, the cross-sectional variance of consumption growth is also a priced factor. This suggests that consumers are not fully insured against idiosyncratic consumption risk, and that asset returns reflect their attempts to reduce their exposure to this risk. The resulting two-factor consumption-based asset pricing m...

摘要：Recent work by Diether, Malloy, and Scherbina (2002) has established a negative relationship between stock returns and the dispersion of analysts' earnings forecasts. I offer a simple explanation for this phenomenon based on the interpretation of dispersion as a proxy for unpriced information risk arising when asset values are unobservable. The relationship then follows from a general options-pricing result: For a levered firm, expected returns should always decrease with the level of idiosync...

摘要：Within a rational general equilibrium model in which agents care only about personal consumption, we consider a setting in which, due to borrowing constraints, individuals endowed with local resources underparticipate in financial markets. As a result, investors compete for local resources through their portfolio choices. Even with complete financial markets and no aggregate risk, agents may herd into risky portfolios. This yields a Pareto-dominated outcome as agents introduce community risk u...

摘要：We test overreaction theories of short-run momentum and long-run reversal in the cross section of stock returns. Momentum profits depend on the state of the market, as predicted. From 1929 to 1995, the mean monthly momentum profit following positive market returns is 0.93%, whereas the mean profit following negative market returns is -0.37%. The up-market momentum reverses in the long-run. Our results are robust to the conditioning information in macroeconomic factors. Moreover, we find that m...

摘要：Banks and related financial institutions often have two separate subsidiaries that make loans of similar type but differing risk, for example, a bank and a finance company, or a good bank/bad bank structure. Such bipartite structures may prevent risk shifting, in which banks misuse their flexibility in choosing and monitoring loans to exploit their debt holders. By insulating safer loans from riskier loans, a bipartite structure reduces risk-shifting incentives in the safer subsidiary. Biparti...

摘要：I study incentives received by outside directors in Fortune 500 firms from compensation, replacement, and the opportunity to obtain other directorships. Previous research has only shown these relations to apply under limited circumstances such as financial distress. Together these incentive mechanisms provide directors with wealth increases of approximately 11 cents per $1,000 rise in firm value. Although smaller than the performance sensitivities of CEOs, outside directors' incentives imply a...
