A SEARCH‐EQUILIBRIUM APPROACH TO THE EFFECTS OF IMMIGRATION ON LABOR MARKET OUTCOMES
利用搜索匹配模型分析2000-2009年美国技能偏向型移民流入的影响，发现移民提高了本土居民总体净收入，但存在分配效应：低技能者就业和工资均受益，高技能者就业增加但工资下降，若两者为不完全替代则高技能工资也上升。
We analyze the impact of the U.S. skill‐biased immigration influx that took place between 2000 and 2009 within a search and matching model that allows for skill heterogeneity, differential search cost, and capital‐skill complementarity. We find that although the skill‐biased immigration raised the overall net income to natives, it had distributional effects. Specifically, unskilled native workers gained in terms of both employment and wages. Skilled native workers, however, gained in terms of employment but lost in terms of wages. Nevertheless, in an extension where skilled natives and immigrants are imperfect substitutes, even the skilled wage rises.
