Endogenous Markups and Fiscal Policy

Author

Listed:
  • Luís F. Costa

Abstract

This note analyses a simple imperfectly competitive general equilibrium model where the entry mechanism generates an endogenous markup. In this second-best world fiscal policy is more effective than in Walrasian or in fixed-markup monopolistic competition models, as it produces efficiency gains through entry.
