OPENING THE FLOODGATES: PARTIAL AND GENERAL EQUILIBRIUM ADJUSTMENTS TO LABOR IMMIGRATION
研究大规模移民冲击对职业工资的影响，构建一般均衡模型分析个体职业选择，利用移民与本地人职业分布差异的工具变量识别效应，发现移民降低了相对职业工资，对本地人福利影响近乎零，但对原有移民群体有负面影响。
Abstract We investigate the impact of a large immigration shock on occupational wages. We develop a general equilibrium model where individuals sort into occupations and confront testable hypotheses with data. To identify the effect of the labor supply shock, we introduce a novel instrument that exploits that immigrants systematically sort into different occupations than natives. We study the immigration wave to Norway after the Eastern enlargement and find that immigration led to lower relative occupational wages. A quantification of the general equilibrium shows welfare effects of immigration close to zero for natives, but negative effects for the pre‐existing population of immigrants.
