We consider a setting where owning stock confers direct utility due to an affect heuristic. Specifically, holding equity in companies with visible brands or environmentally conscious products yields positive consumption benefits, whereas investing in sin stocks yields the reverse. We find that...

High levels of turnover in financial markets are consistent with the notion that trading, like gambling, yields direct utility to some agents. We show that the presence of these agents attenuates covariance risk pricing and volatility, and implies a negative relation between volume and future...

We analyze a model with information asymmetry where owning stock confers direct utility, in addition to impacting wealth. In contrast to settings based on wealth considerations alone, expected stock prices deviate from expected fundamentals even when assets are in zero net supply. Stocks that...

How might markets exhibit both short-term reversals and longer-term momentum? Motivated by this question, we develop a dynamic model which includes noise traders and investors who underreact to signals that they do not themselves produce. Our setting implies the following: Return predictability...
