Regionalism and Multilateral Trade Liberalization with Asymmetric Countries

Abstract The paper examines the impact of regionalism on the process of multilateral trade liberalization when countries are asymmetric. The author uses a three‐country, three‐good, competing exporters model, with countries being symmetric in everything but their discount factors. The equilibrium regional agreement is found to be a customs union between a patient and an impatient country and that the impact of regionalism depends on the discount factors. The impact of regionalism on multilateral trade liberalization depends critically on which countries engage in regionalism.
