Immigration and Wage Dynamics: Evidence from the Mexican Peso Crisis Joan Monras∗ Sciences Po November 30, 2015 Abstract How does the US labor market absorb low-skilled immigration? I address this question using the 1995 Mexican Peso Crisis, an exogenous push factor that raised Mexican migration to the US. In the short run, high-immigration states see their low-skilled labor force increase and native low-skilled wages decrease, with an implied inverse local labor demand elasticity of at least -.7. Internal relocation dissipates this shock spatially. In the long run, the only lasting consequences are for low-skilled natives who entered the labor force in high-immigration years. A simple quantitative many-region model allows me to obtain the counterfactual local wage evolution absent the immigration shock. Key Words: International and internal migration, local shocks, local labor demand elasticity. JEL Classification: F22, J20, J30 ∗Economics Department and LIEPP. Correspondence:
