Motivated by the recent debate on return R2 as an information-efficiency measure, this paper proposes and examines a new hypothesis that R2 is related to investors’ biases in processing information. We provide a model to show that R2 decreases with the degree of the marginal investor’s...

This study seeks to identify which factors are important for explaining the time-series and cross-section variation in global stock returns. We evaluate firm characteristics, like size, earnings/price, cash flow/price, dividend/price, book-to-market equity, leverage, momentum, that have been...

Firms in more concentrated industries earn lower returns, even after controlling for size, book-to-market, momentum, and other return determinants. Explanations based on chance, measurement error, capital structure, and persistent in-sample cash flow shocks do not explain this finding. Drawing...

We propose a new approach to estimate the implied cost of capital (ICC). Our approach is distinct from prior studies in that we do not rely on analysts' earnings forecasts to compute the ICC. Instead, we use a cross-sectional model to forecast the earnings of individual firms. Our approach has...

Recent studies report that the size effect in the cross-section of U.S. stock returns has disappeared after the early 1980s. We examine whether the disappearance of the size effect in realized returns can be attributed to unexpected shocks to the profitability of small and big firms. We show...

We study heterogeneity in the comovement of corporate bonds and equities, both at the bond level and at the firm level. Using an extended Merton model, we illustrate that corporate bonds that mature late relative to the rest of the bonds in its issuer's maturity structure should have stronger...

We propose a simple methodology to evaluate a large number of potential explanations for the negative relation between idiosyncratic volatility and subsequent stock returns (the idiosyncratic volatility puzzle). We find that surprisingly many existing explanations explain less than 10% of the...
