The optimal investment-dividend policy of a financially constrained firm whose earnings are subject to additive shocks is shown to exhibit several stylized economic and financial features of the firm life cycle which usually require considerably more complex models. This parsimonious model...

This paper investigates the role that the entry and exit of heterogeneous firms plays in shaping aggregate fluctuations in economic activity. In so doing, it develops a dynamic stochastic general equilibrium model in which procyclical entry and countercyclical exit along a real business cycle...

We analyze a general equilibrium model of firm dynamics to study the effects of shocks to productivity, labor wedge, and collateral constraint (credit shock) on firm exit. We find that only the credit shock increases firm exit. This result is robust to the magnitude of shocks and different model...
