Our paper explores the link between cross-sectional fund return dispersion and performance evaluation. The foundation of our model is the simple intuition that in periods of high return dispersion, which is associated with high levels of idiosyncratic risk for zero-alpha funds, it is easier for...

We show theoretically that when Bayesian investors face time-series uncertainty about assets' risk exposures, differences in their priors affect the pricing of risk in the cross-section: different priors for the same asset can generate differences in perceived risk exposures, and thereby...

Many regulations that affect firms and banks in the economy are based on size thresholds. We develop a model that shows that such regulations distort risk-taking incentives, providing above-threshold firms with greater incentives to take risk and below-threshold firms the opposite. Risk...

Product-harm crises can adversely affect brand equity and advertising effectiveness. We develop state space models to capture brand and sub-brand equity the dynamics related to product recalls and spending on different levels and types of advertising, integrate them with a random coefficient...
