We conclude that individual aid sector volatility matters as well as total aid volatility. Easily, the most important contributor to total volatility is debt aid. The most volatile aid sectors per se include debt, industry, and humanitarian, and the least include education and health. In several sectors volatility appears to have peaked around 2006.
