大量文献研究了基础设施如何促进贸易。我们问基础设施是否也促进了移徙。使用一般均衡贸易模型和丰富的空间数据，我们研究了一个大的，合理的外生冲击，在巴西的高速公路上的商品和劳动力市场的影响。我们发现，高速公路系统使福利增加了2.8%，其中76%是由于贸易成本降低，24%是由于移民成本降低。代价高昂的移民的一个含义是利益的空间异质性：福利改善的范围是1%到15%，而不是完全流动的均匀收益。(JEL H54、H76、O18、R23、R42、R53）
A large body of literature studies how infrastructure facilitates trade. We ask whether infrastructure also facilitates migration. Using a general equilibrium trade model and rich spatial data, we study the impact of a large, plausibly exogenous shock to highways in Brazil on both goods and labor markets. We find the highway system increased welfare by 2.8 percent, of which 76 percent was due to reduced trade costs and 24 percent to reduced migration costs. An implication of costly migration is spatial heterogeneity in benefits: the range of welfare improvement is 1 to 15 percent, as opposed to uniform gains with perfect mobility.
