This paper explores the impact of donor supervision on development project performance using data from World Bank-funded projects. Maximum likelihood estimation of a restricted ordered probit function finds that early supervision has a positive impact on performance. Given the size of World Bank-funded projects, gains from increasing supervision far outweigh the costs. The results provide evidence of an institutional bias toward lending at the expense of increased development impact.
