# Oligopolistic vs. monopolistic competition: Do intersectoral effects matter?

Recent extensions of the standard Dixit–Stiglitz (Am Econ Rev 67:297–308, 1977) model, that go beyond the CES sub-utility assumption while maintaining monopolistic competition, have mainly emphasized the role of intrasectoral substitutability. We argue that introducing oligopolistic competition can be an alternative extension, still tractable, allowing to restore the role of intersectoral substitutability and reinforcing the general equilibrium dimension of the model. For this purpose, we…

Abstract This paper proposes a model of a continuum of industries in which some industries are monopolistically competitive, the others are oligopolistic, and they interact in a labor market. We use…

Equilibria and optima generally differ in imperfectly competitive markets. While this is well understood theoretically, it is unclear how large the welfare distortions are in the aggregate economy.…
