We introduce Cournot competition and endogenous entry in an oth- erwise neoclassical macroeconomic framework. First, we develop a model with exogenous savings à la Solow describing the dynamic path of busi- ness creation. Then, we develop a model à la Ramsey describing the dynamic interaction of consumption and business creation. Our models are able to explain why markups vary countercylically and pro?ts are procyclical. The analysis of permanent and temporary technology and preference shocks and of the second moments suggests that our model can outperform the Real Business Cycle framework in many dimensions.

Abstract
We introduce Cournot competition and endogenous entry in an oth- erwise neoclassical macroeconomic framework. First, we develop a model with exogenous savings à la Solow describing the dynamic path of busi- ness creation. Then, we develop a model à la Ramsey describing the dynamic interaction of consumption and business creation. Our models are able to explain why markups vary countercylically and pro?ts are procyclical. The analysis of permanent and temporary technology and preference shocks and of the second moments suggests that our model can outperform the Real Business Cycle framework in many dimensions.
