Firm Level Productivity, Risk, and Return

Abstract

This paper provides new evidence about the link between firm level total factor productivity (TFP) and stock returns. We estimate firm level TFP and show that it is strongly related to several firm characteristics such as size, the book to market ratio, investment, and hiring rate. Low productivity firms earn a significant premium over high productivity firms in the following year, and this premium is countercyclical. We show that a production based asset pricing model calibrated to match the cross section of measured firm level TFPs can replicate the empirical relationship between TFP, many firm characteristics, and stock returns. Our results offer an explanation as to how these firm characteristics rationally predict returns.
