Road Maintenance and Local Economic Development

Abstract

This paper estimates the local welfare impacts of highway maintenance investments. We instrument road quality exploiting Indonesia’s two-step budgeting process for allocating funding to local road authorities. Using comprehensive data on road quality from 1990-2007, we find evidence that better roads help manufacturers create new jobs, enabling worker transitions out of informal employment, and increasing labor income. Road quality also changes the cost of living, reducing perishable food prices but also raising housing prices. We estimate the elasticity of household welfare with respect to road quality to be 0.09 and the benefit/cost ratio for road maintenance investments to be 1.8.
