【 摘 要 】
The connections between transportinfrastructure and economic development have beenextensively analyzed in previous research, but little isknown about the cost of infrastructure investments in poorcountries. This paper examines drivers of unit costs ofconstruction and maintenance of transport infrastructure inlow and middle income countries and documents that: (i)there is a large dispersion in unit costs for comparableroad work activities; (ii) after accounting forenvironmental drivers of costs, residual unit costs aresignificantly higher in conflict countries; (iii) there isevidence that costs are higher in countries with higherlevels of corruption; (iv) these effects are robust tocontrolling for a country’s public investment capacity andbusiness environment. Our findings have implications forgovernments aiming to increase connectivity in poor countries.
