This paper provides a framework for the analysis of firms' integration strategies that incorporates the endogenous determination of the number of firms that serve foreign markets through exports and the number of multinational firms that choose to engage in horizontal foreign direct investments....

This paper provides a theory of the international business cycle grounded on firms' entry and sticky prices. It shows that under simple monetary rules pro-cyclical entry and counter-cyclical markups can generate fluctuations in macroeconomic aggregates and trade variables as large as those...

This note studies the synchronization of firm entry and markups in a DSGE model with nominal frictions. Simulations show that the model matches the comovement of markups and entry observed in the data while at the same time reproducing empirically plausible moments for macroeconomic variables. I...

This paper studies the business cycle implications of entry costs in a dynamic stochastic general equilibrium model with firm entry and nominal rigidity. Simulations show that my baseline model matches the dynamics observed in the data fairly well. Remarkably, it overcomes the difficulties...
