 Abstract:

The last U.S. recession stands out not only for its depth, but also for the rather slow recovery that followed it. What is less well known is that the number of productive units also dropped substantially, while it barely budged in occasion of the 1981 recession, and kept increasing during the 1991 and 2001 recessions. To the extent that the stock of establishments is a very slow–moving variable, a recession characterized by an unusually large drop in establishments will necessarily be followed by a slow recovery. In order to evaluate the quantitative significance of this mechanism, we build a general equilibrium business cycle model with heterogenous firms and endogenous entry and exit, and calibrate it so that the implied unconditional average firm–level and aggregate dynamics are consistent with the empirical evidence. Preliminary results show that recessions characterized by a sizeable drop in entry rates stand out along two dimensions: (1) The response of output in hump-shaped, meaning that output can diverge from trend for years following a negative mean–reverting shock; (2) The recovery is substantially slower.
