Firm-specific information can affect expected returns if it affects investor uncertainty about risk-factor loadings. We show that a stock's expected return is decreasing in factor-loading uncertainty, controlling for the average level of its factor loading. When loadings are persistent, learning...

Reputational concerns have commonly been perceived to have a positive effect on auditing firms' execution of their monitoring and attesting functions. This paper demonstrates that this need not always be the case by studying a two-period game of repeated interaction between a manager and an...

We examine a duopolistic setting in which firms can preannounce their future competitive decisions before they actually implement them. We show that there is a unique equilibrium in which both firms preannounce and overstate their future actions when uncertainty of demand is low. We find that...

The article develops a dynamic model that nests the rational expectations (RE) and differences of opinion (DO) approaches to study how investors use prices to update their valuations. When investors condition on prices (RE), investor disagreement is related positively to expected returns, return...

Regulatory restrictions and market frictions can constrain the aggregate quantity of long and short positions in a security. When these constraints bind, we refer to the security as scarce, and its price becomes distorted relative to its value in a frictionless market. We show that an otherwise...
