Train to Opportunity: the Effect of Infrastructure on Intergenerational Mobility

Abstract Can transport infrastructure expand long-term labour opportunities and weaken the occupational link between parents and children? We estimate the causal effect of railway access on occupational attainment and intergenerational mobility in nineteenth-century England and Wales. Exploiting the as-good-as-random opening of built and planned stations, we address endogeneity in rail proximity. Sons living 5 km closer to a station were more likely to leave farming for industrial and commercial jobs, often entering the top quartile of the occupational distribution. Railway access increased the probability of working in a different occupation than one’s father by 2% and of upward mobility by 6%.
