"The purpose of much foreign aid is to reduce poverty and encourage progress in developing nations. Toward that end, Roodman's CGD has attempted to capture other policies to construct a Commitment to Development Index for 21 rich nations. Here the United States comes in much better, at No. 7. The index considers trade policy, foreign investment, immigration, environmental policy, technology, and security (some military assistance), as well as official and private aid in ranking the generosity of nations."
