Using novel corporate Twitter data on all U.S. public firms, we show that firms with a Twitter account earn 50 basis points per month higher returns than similar firms without a Twitter account. This `Twitter premium' is higher among smaller firms and firms with higher fundamentals uncertainty,...

The primary purpose of this research is to empirically test a new asset pricing model, the Relative Asset Pricing Model (RAPM), and to confirm whether hedge portfolios on two new risk factors highlighted in that model, and embedded in all portfolios, have negative and significant risk premia. In...

We examine the time-series relation between aggregate bid-ask spreads and conditional equity premium. We document that average market-wide relative effective bid-ask spreads forecast aggregate market returns only when controlling for average idiosyncratic variance. This control allows us to...

We test the implications of the return decomposition of Campbell (1991), in which the unexpected market return is decomposed into cash-flow and discount-rate news. Unlike most of the previous literature, which uses VAR models to implement the return decomposition, we propose a state-space model...

We provide a simple but fairly general theoretical model that produces many of the implications regarding the value premium and stock volatility suggested in prior empirical literature and provides a number of new implications. Our equilibrium model naturally incorporates technological...

Existing empirical findings on the validity of catering theory of dividend policy are mixed at the aggregate-market level, while there is little cross-sectional evidence based on individual firms, which is necessary for studying investor preferences for dividend policy with greater resolution....

Based on information signaling theory, this paper empirically shows that distribution effect matters for idiosyncratic volatility discount. Idiosyncratic volatility discount arises primarily among stocks with non-cash distributions. Such stocks show a significant idiosyncratic volatility...

Existing models of mortgage default cannot explain variation in mortgage performance across origination years because they do not account for the “convenience yield” households derive from owning, rather than renting, a home. The convenience yield is the flow of services from owning rather...

We describe four channels through which breakups can potentially increase idiosyncratic volatility for parent firms. These are: loss of diversification (portfolio effect), change in growth opportunities, change in operational efficiency, and the flow and assimilation of information (information...
