Wes sent me a link to the latest/greatest new source of data on international aid/development finance:
They compile information on development finance (i.e., grants and loans) from governments and IGOs to developing countries for the period 1947-2009.
We are using it to expand on a paper, which we presented at ASA last August, that looked at the impact of World Bank “structural adjustment” loans on national income inequality. (We found that loans are associated with generally higher inequality in the 1980s; but not in the 1990s and not in Asia.) This database will allow us to look at IMF loans, and other sources as well.
Also: In the future, they plan to add data on aid from NGOs and private groups. That will be really useful.
