We argue that the rationalization gains often predicted by static applied general equilibrium models with imperfect competition and scale economies are artificially boosted by an unrealistic treatment of fixed costs. We introduce sunk costs into one such model calibrated with real-world data. We...

This article investigates the international duopoly equilibrium when two countries impose antidumping constraints. It shows that, depending on the parameters of the model, three Nash equilibria exist: one in which both firms trade, one in which no firm trades and one in which a single firm trades.

The authors argue that the rationalization gains often predicted by static applied general equilibrium models with imperfect competition and scale economies are artificially boosted by an unrealistic treatment of fixed costs. They introduce sunk costs into one such model calibrated with...

Using the Hotelling approach to product differentiation, this article derives the equilibrium product configurations and prices when two firms enter and sell in two interdependent markets separated by barriers to trade. It shows that product imitation and no trade as well as product...

This paper investigates the effects of reciprocal tariff reductions in a two-identical country model of product differentiation. It makes three points. First, the existing results about market structure effects of trade liberalization can easily be replicated from a one-dimensional...
