The Effect of Customs Unions Among Specialized Countries on International Capital Flows*

This paper examines the effect on international capital flows of a customs union formed by specialized countries. We assume no economies of scale, and use a general equilibrium model with internationally mobile capital. It is shown that integration among countries with characteristics generally associated with having specialized economies will lead to a flow of capital into the union. These characteristics specifically concern the types of goods they trade among themselves, and with the rest of the world, and their ability to absorb capital inflows.
