The paper examines the effect of aid on "poverty", rather than on economic growth. We devise a 'pro-poor (public) expenditure index', and present evidence that, together with inequality and corruption, this is a key determinant of the aid's poverty leverage. After presenting empirical evidence...

We review experimental evidence collected from risky choice experiments using poor subjects in Ethiopia, India and Uganda. Using these data we estimate that just over 50% of our sample behaves in accordance with expected utility theory and that the rest subjectively weight probability according...
