Abstract

This paper studies the welfare consequences of monetary policy in a sticky wage New Keynesian model with heterogenous firms and endogenous entry. Cross-sectional dispersion in price-markups and labor shares is generated by a translog demand structure and aggregate fluctuations in these variables are driven by firm entry and selection. We show that when the distribution of firm-level productivity is Pareto, selection is such that the aggregate price-markup and labor share are fixed. If firm entry is static, the divine coincidence appears, and wage stability is optimal. If firm entry is dynamic, or selection is weakened, optimal stabilization policy accounts for the size distribution of firms. We calculate the welfare loss of ignoring firm entry and selection to be 0.1 − 0.3 percent of steady state consumption.
