Does immigration accelerate sectoral change towards high-productivity sectors? This paper uses the mass displacement of ethnic Germans from Eastern Europe to West Germany after World War II as a natural experiment to study this question. A simple two-sector specific factors model, in which moving costs prevent the marginal product of labor to be equalized across sectors, predicts that immigrati...
