The Inter-American Development Bank (IDB) works exclusively in Latin America. It has just concluded a study and published a book called So- cial Investment Funds in Latin America: Past Performance and Future Role. It occurred about two years ago that social funds have become overwhelm- ingly popular all over the world. They started out as a way of respond- ing to adjustment and have developed in different ways, doing various things. The IDB decided to look at them to determine what is working and what is not working. The Canadians, the Germans, the Swedes, and the Organization of American States (OAS) also thought the subject de- served review, so.
