How do changes in market structure affect the US business cycle? We estimate a monetary DSGE model with endogenous fi…rm/product entry and a translog expenditure function by Bayesian methods. The dynamics of net business formation allow us to identify the extent to which desired price markups and in‡flation decrease when entry rises. We …find that a 1 percent increase in the number of competitors lowers desired markups by 0.17 percent. While markup ‡fluctuations due to sticky prices or exogenous shocks account for a large proportion of US infl‡ation variability, endogenous changes in desired markups also play a non-negligible role.

Keywords: Bayesian estimation, business cycles, competition, entry, markups
