Agriculture, Roads, and Economic Development in Uganda

A large fraction of Uganda's population continues to earn a living from quasi-subsistence agriculture. This paper uses a static general equilibrium model to explore the relationships between high transportation costs, low productivity, and the size of the quasi-subsistence sector. We parameterize the model to replicate some key features of the Ugandan data, and we then perform a series of quantitative experiments. Our results suggest that the population in quasi-subsistence agriculture is highly sensitive both to agricultural productivity levels and to transportation costs. The model also suggests positive complementarities between improvements in agricultural productivity and transportation.
