This paper analyses the effect of firm learning on labor market efficiency in a frictional labor market with asymmetric information. I consider a model with random matching and wage bargaining a la Pissarides (1985, 2000) where worker ability is unknown to firms at the hiring stage. Firm learning increases relative expected earnings in high-ability jobs and, thereby, enhances imitation incentives of low-ability workers. The net effect on aggregate expected match surplus and unemployment is indeterminate a priori. Numerical results show that firm learning does not increase labor market efficiency.
