Native Competition and Low-Skilled Immigrant Inflows

Area of Science:

• Economics
• Sociology
• Labor Market Analysis

Background:

• Immigration decisions are complex, influenced by various economic and social factors.
• Understanding the impact of local labor market conditions on immigrant inflows is crucial for policy-making.

Purpose of the Study:

• To demonstrate that immigration decisions are directly dependent on local labor market conditions.
• To quantify the response of low-skilled immigrant inflows to changes in the US-born labor supply.

Main Methods:

• Utilized pre-reform welfare participation rates as an instrumental variable for changes in native labor supply.
• Analyzed the correlation between supply shocks in the native labor force and immigrant inflows in local markets.
• Employed econometric techniques to establish causality and measure the magnitude of the response.

Main Results:

• Immigrants competing with native workers systematically avoid locations with significant increases in labor supply (supply shocks).
• A substantial response was documented: for every native woman entering the workforce due to reform, 0.5 fewer female immigrants entered the local labor force.
• The findings indicate that international migration flows help to equalize economic returns across different US local labor markets.

Conclusions:

• Local labor market conditions are a significant determinant of immigration patterns.
• Immigration acts as an equilibrating force, responding to and mitigating labor supply variations.
• The study provides direct empirical evidence supporting the role of migration in balancing labor markets.
