Haufler, A. and Wooton, I. (2010) Competition for firms in an oligopolistic industry : the impact of economic integration. Journal of International Economics, 80 (2). pp. 239-248. ISSN 0022-1996
We set up a model of generalised oligopoly where two countries of different size compete for an exogenous, but variable, number of identical firms. The model combines a desire by national governments to attract internationally mobile firms with the existence of location rents that arise even in a symmetric equilibrium where firms are dispersed. As economic integration proceeds, equilibrium taxes initially decline, but then rise again as trade costs fall even further. A range of trade costs is identified where economic integration raises the welfare of the small country, but lowers welfare in the large country.
