The Long-Run Development Impacts of Agricultural Productivity Gains: Evidence from Irrigation Canals in India, with Sam Asher, Ali Campion, and Paul Novosad.
ABSTRACT: How do investments in agricultural productivity translate into development and structural transformation? We estimate the long-run impacts of India's irrigation canals, which span 300,000+ km and deliver water to 130,000+ villages. Drawing on high-resolution data on every household, firm, village, and town in India, we use three empirical strategies to characterize the direct and spillover effects of large increases in agricultural productivity. Decades after canal construction, directly treated areas have sharply higher agricultural productivity and population density, but similar non-farm employment shares to non-canal areas. Persistent consumption gains accrue only to landowners and structural transformation occurs exclusively through the concentrated growth of regional towns. Our findings are consistent with a spatial equilibrium model in which labor is mobile, and urban areas have non-farm productivity advantages. In the long run, the substantial productivity effects of canals were equilibrated through the movement of labor across space rather than within locations across sectors.
