Abstract

This paper documents the effect of road construction on city population growth in sub-Saharan Africa from 1960-2010 through the channel of increasing market access. Using changes in market access due to foreign or otherwise distant road construction as a source of exogenous variation in overall market access, the study estimates a 30-year elasticity of city population with respect to market access of 0.05 to 0.20, larger than OLS estimates of 0.02–0.05, but somewhat smaller than estimates for other contexts. The effect is concentrated 10–30 years after road construction, closer to coasts and borders, and farther from a country’s largest cities.
