Immigration, Human Capital Formation, and Endogenous Economic Growth
利用覆盖全球77%移民人口的普查数据，发现主要目的地国高技能移民占比持续上升，并通过内生增长模型分析移民对长期收入增长和分配的影响。
Census data from international sources covering 77 percent of the world’s migrant population indicate that the skill composition of migrants in major destination countries, including the United States, has been rising over the last four decades. Moreover, the population share of skilled migrants has been approaching or exceeding that of skilled natives. We offer theoretical propositions and empirical tests consistent with these trends via a general equilibrium model of endogenous growth in which human capital, population, income growth and distribution, and migration trends are endogenous. We derive new insights about the impact of migration on long-term income growth and distribution and the net benefits to natives in both destination and source countries.
