Endogenous Market Structures in International Trade
Ignatius J. Horstmann, James R. Markusen
Almost all of the large literature on international trade with imperfect competition assumes exogenous market structures. The purpose of this paper is to develop a simple model that generates alternative market structures as Nash equilibria for different parameterizations of the basic model. Familiar configurations such as a duopoly competing in exports or a single multinational producing in both markets arise as special cases. Small tax-policy changes can produce large welfare effects as the equilibrium market structure shifts, implying discontinuous jumps in prices, quantities, and profits.
