The economics literature generally finds a positive, but small, gain in income to native-born populations from immigrants and potentially large gains in world incomes. But immigrants can also impact a recipient nation’s institutions. A growing empirical literature supports the importance of strong private property rights, a rule of law, and an environment of economic freedom for promoting long run prosperity. Although the literature on the impact of economic freedom on various social and economic outcomes is quite large, comparatively little work has tried to explain economic freedom as a dependent variable. This paper empirically examines how immigration impacts a region’s policies and institutions. We find small but positive increases in institutional quality as a result of immigration.
