We offer a new social approach to investment decision making and asset prices. Investors discuss their strategies and convert others to their strategies with a probability that increases in investment returns. The conversion rate is shown to be convex in realized returns. Unconditionally, active...

We examine the causal effect of limits to arbitrage on 11 well-known asset pricing anomalies using Regulation SHO, which relaxed short-sale constraints for a random set of pilot stocks, as a natural experiment. We find that the anomalies became weaker on portfolios constructed with pilot stocks...
