摘要：The prevailing view in finance is that the evidence for long-horizon stock return predictability is significantly stronger than that for short horizons. We show that for persistent regressors, a characteristic of most of the predictive variables used in the literature, the estimators are almost perfectly correlated across horizons under the null hypothesis of no predictability. For the persistence levels of dividend yields, the analytical correlation is 99% between the 1- and 2-year horizon es...

摘要：The Review of Financial Studies has among its missions the facilitation and promotion of a vigorous academic debate across unsettled questions in finance. This issue represents a cross section of views regarding one such debate: Can ourempirical models accurately forecast the equity premium any better than the historical mean ? Or, is the forecast our empirical models give us any more accurate than what we would get by simply using the historical mean ?

摘要：Using a sample of municipal bond offerings, I find that local investment banks have substantial comparative and absolute advantages over nonlocal counterparts--locals charge lower fees and sell bonds at lower yields. Local investment banks' strongest comparative advantage is at underwriting bonds with higher credit risk and bonds not rated by rating agencies. These findings suggest that high-risk bonds and nonrated bonds are more difficult to evaluate and market, and that investment banks with...

摘要：Using a new technique, and weekly data for 25 countries from 1994 to 1998, we analyze the relationship between institutional cross-border portfolio flows, and domestic and foreign equity returns. In emerging markets, institutional flows forecast statistically indistinguishable movements in country closed-end fund NAV returns and price returns. In contrast, closed-end fund flows forecast price returns, but not NAV returns. Furthermore, institutional flows display trend-following (trend-reversin...

摘要：We have developed Bayesian Markov chain Monte Carlo (MCMC) methods for inferences of continuous-time models with stochastic volatility and infinite-activity Levy jumps using discretely sampled data. Simulation studies show that (i) our methods provide accurate joint identification of diffusion, stochastic volatility, and Levy jumps, and (ii) the affine jump-diffusion (AJD) models fail to adequately approximate the behavior of infinite-activity jumps. In particular, the AJD models fail to captu...

摘要：Aggregate stock prices, relative to virtually any indicator of fundamental value, soared to unprecedented levels in the 1990s. Even today, after the market declines since 2000, they remain well above historical norms. Why? We consider one particular explanation: a fall in macroeconomic risk, or the volatility of the aggregate economy. Empirically, we find a strong correlation between low-frequency movements in macroeconomic volatility and low-frequency movements in the stock market. To model t...

摘要：We theoretically and empirically investigate the role of information on the cross section of stock returns and firms' cost of capital when investors face estimation risk and learn from noisy signals of uncertain quality. The resultant equilibrium is an information-dependent conditional CAPM. We find strong empirical support for the model. Innovations in market volatility, oil prices, exchange rates, and dispersion of analysts' forecasts not only help explain the cross section of stock returns,...

摘要：An investment factor, long in low-investment stocks and short in high-investment stocks, helps explain the new issues puzzle. Adding the investment factor into standard factor regressions reduces the SEO underperformance by about 75%, the IPO underperformance by 80%, the underperformance following convertible debt offerings by 50%, and Daniel and Titman's (2006) composite issuance effect by 40%. The reason is that issuers invest more than nonissuers, and the investment factor earns a significa...

摘要：Microstructure researchers have long understood that information quality has an effect on price formation in the underlying asset market. However, option researchers have largely ignored the fact that information quality might also impact the options market. This article characterizes the nature of the impact by showing how option prices and implied volatility levels are related to the forward looking information quality path. This result follows from a noisy rational expectations model that a...

摘要：Using earnings announcement events made by firms belonging to Korean chaebols, we examine propping within a chaebol. Consistent with the market's ex ante valuation of intragroup propping, we find that the announcement of increased (decreased) earnings by a chaebol-affiliated firm has a positive (negative) effect on the market value of other nonannouncing affiliates. The sensitivity of the change in the market value of nonannouncing affiliates to abnormal returns for the announcing firms is hig...
