Has foreign aid been helpful for development? What helps and hinders it? What does the evidence say?
The key challenge facing foreign aid globally is its effectiveness.
Research on aid effectiveness has focused on outcomes such as a country’s economic growth or quality of institutions. These studies came to mixed conclusions over whether aid can effectively promote economic development.
Microeconomic evidence paints a reasonably positive picture. The World Bank’s Independent Evaluation Group (IEG) finds that the average rates of return to aid are generally above 20%. Evidence based on randomized program evaluation techniques is also largely positive, indicating that aid-financed interventions can generate substantial benefits for individuals.
