Immigrant Inflows, Native Outflows, and the Local Labor Market Impacts of Higher Immigration
利用1990年人口普查数据，研究移民流入对特定职业劳动力市场的影响，发现移民流入降低了低技能本地人在传统门户城市的工资和就业率1-3个百分点。
This article uses 1990 census data to study the effects of immigrant inflows on occupation-specific labor market outcomes. I find that intercity mobility rates of natives and earlier immigrants are insensitive to immigrant inflows. However, occupation-specific wages and employment rates are systematically lower in cities with higher relative supplies of workers in a given occupation. The results imply that immigrant inflows over the 1980s reduced wages and employment rates of low-skilled natives in traditional gateway cities like Miami and Los Angeles by 1-3 percentage points.
