【摘要】This paper studies the implications of labor reallocation for the welfare effects of transportation infrastructure in a quantitative spatial model with costly trade and migration. Migration frictions generate imperfect spatial arbitrage of individual well-being and imply that the impacts of transportation infrastructure depend on the change in labor flow across locations. Our analyses on the highway expansion in China indicate a difference in the extent of labor reallocation over time. We show that labor reallocation accounts for 4% of the overall welfare gains from highway construction in the short run but 25% in the long run. The distributional effects of highway construction also differ due to the reversal in migration flows between small and large cities.
