The economics of korean unification

Abstract
We simulate the impact of a customs union and an exchange rate unification of North and South Korea. Factor mobility and technological change are of critical importance. If factor markets do not integrate, the macroeconomic impact on South Korea of economic integration is relatively small, while the effects on North Korea are large. With factor market integration, there is a significant impact on the South Korean income and wealth distribution. If integration is accompanied by external capital inflows, there is a significnt appreciation of the real exchange rate with deleterious implications for the South Korean traded-goods sector.
