Technical Guidance Note on Assessing the Welfare and Distributional Impacts of Private Sector Participation in Infrastructure Interventions

This Note introduces key evaluation approaches and methods that can produce credible evidence about the welfare and distributional impacts of infrastructure interventions. Evaluating both types of impact is crucial because the ultimate objective of public policy is to improve the well-being of the population, and particularly that of the poorest and the most vulnerable in society. The Note focuses on infrastructure because across the developing world, inadequate infrastructure remains a major constraint to achieving the Sustainable Development Goals (SDGs) and the World Bank Group’s (WBG’s) goals of ending extreme poverty by 2030 and promoting shared prosperity (income growth of the bottom 40 percent in every country). To bridge the infrastructure gap, the WBG and other development actors are committed to leveraging all sources of finance, expertise, and solutions, including those of the private sector.
