The World Bank has ratings for its development projects. The dataset is comprehensive, but crucial details, like return on investment, are missing.
What are other sources of data on projects in international development, such as power plants, roads, investments in equipment, and so on? Maybe some governments disclose information about their projects? Or organizations besides the World Bank?
Return on investment, IRR, and other financial metrics would be extremely appreciated, but I would also be glad to have any related information on large development projects.
