A simple dynamic general equilibrium model is set up in which firms face idiosyncratic productivity shocks. Firms whose productivity has fallen too low exit, and entrants try to imitate the practice of existing firms, so that the expected productivity of entering firms is a function of current average productivity.

When calibrated to U.S. data, the model suggests that around 50 percent of productivity growth may be due to such a selection e¤ect
