The success of infrastructure projects in low-income countries and the role of selectivity

This research analyzes the success of the infrastructure projects financed by the World Bank, focusing on the causal link between the quality of project implementation and its outcome. The results show that the success of infrastructure projects depends fundamentally on the quality of implementation. Although bad implementation can harm structurally solid projects, good implementation cannot make structurally weak projects successful. This leads to the conclusion that governance and selection of well-designed projects are essential for success and, in order to improve project outcomes, multilateral development banks may need to align their incentives toward this objective and invest more in governance and capacity building.
