Title: How is foreign aid spent?
Description: We use oil price fluctuations to construct a new instrument to test the impact of transfers from wealthy OPEC nations to their poorer Muslim allies. The instrument identifies plausibly exogenous variation in foreign aid. We investigate how aid is spent by tracking its short-run effect on aggregate demand, the national accounts, and the balance of payments. We find that much aid is consumed, primarily in the form of imported non-capital goods. Some aid is invested and aid has a positive, though statistically imprecise, effect on growth. Aid has no effect on the financial account but leads to unaccounted capital flight.
