Immigrants and Human-Capital Investment
从理论和实证角度探讨为何移民比本土出生者更倾向于投资人力资本，以及不同移民类型的投资模式差异。研究发现，移民缺乏美国特定技能导致机会成本较低、未转移人力资本作为生产因素、以及外国与美国人力资本的互补性提高了投资回报，这些因素共同促进了移民的人力资本投资。
The following question is approached theoretically and empirically: Why do immigrants invest more in human capital than the native-born, and how do investment patterns vary by type of immigrant? It is found that greater immigrant human capital investment is due to the lower opportunity costs of investment by immigrants lacking US-specific skills and the role of untransferred human capital as a factor of production for destination-country skills, as well as the higher return to investment spending from the complementarity of foreign and US human capital. This theoretical insight is supported by direct evidence of human capital investment and by empirical analyses.
