The Age of Mass Migration (1850-1913) was among the largest migration episodes in history. During this period, the United States maintained open borders. Using a novel dataset of Norway-to-US migrants, we estimate the return to migration while accounting for migrant selection across households...

Four million blacks left the South from 1940 to 1970, doubling the northern black workforce. I exploit variation in migrant flows within skill groups over time to estimate the elasticity of substitution by race. I then use this estimate to calculate counterfactual rates of wage growth. I find...
