We find evidence that is consistent with the hypothesis that daily mutual fund flows may be instruments for investor sentiment about the stock market. We use this finding to construct a new index of investor sentiment, and validate this index using data from both the United States and Japan. In...

This paper investigates whether one can profit from the size, book-to-market, or momentum anomaly, when price-impact costs are taken into account. A non-linear price-impact function is individually estimated for 5173 stocks to assess the magnitude of trading costs. Compared to constant...

This paper studies an overlapping generations model with multiple securities and heterogeeously informed agents. There are two types of multiplicity of equilibria, one due to noisy rational expectations and the other resulting from self-fulfilling prophecies. Under general conditions, there...

This paper studies an overlapping generations model with multiple securities and heterogeneously informed agents. The model produces multiple equilibria, including highly volatile equilibria that can exhibit strong or weak correlations between asset returns - even when asset supplies and future...

This paper examines the pricing implications of time-variation in assets' market betas over the business cycle in a conditional CAPM framework. We use a half century of real GDP growth expectations from economists' surveys to determine forecasted economic states. This approach largely avoids the...
