Real Anomalies

We examine the importance of cross-sectional asset pricing anomalies (alphas) for the real economy. We develop a novel quantitative model of the cross-section of firms that features lumpy investment and informational inefficiencies, while yielding distributions in closed form. Our findings indicate that anomalies can cause material real inefficiencies, raising the possibility that agents that help to eliminate them add significant value to the economy. The framework reveals that the magnitude of alphas alone is a poor indicator of real implications, and highlights the importance of alpha persistence, the amount of mispriced capital, and the Tobin's q of firms affected
