We consider a standard two-country environment, where one of the two countries has a rigid labor market, and analyze how global economic integration affects the economies with respect to expectations-driven cycles and steady state welfare. We show that by allowing free capital mobility, equilibrium indeterminacy is exported from the rigid wage country to the world economy. If further liberalization is permitted, by allowing free movements of labor, the scope for indeterminacy is reduced and open labor markets may produce a stabilizing effect on the global macro-economy. Whether this also implies higher welfare in the long run depends on differentials in average firm size across countries, which determines the direction of migration flows.
