How can the impact of aid be estimated in the presence of fungibility? And how far does fungibility reduce its benefits? These questions are analyzed in a context where a donor wants to target its efforts on a specific sector and specific geographic areas. A traditional...

The present paper argues that the correct experiment to evaluate the effects of a fiscal adjustment is the simulation of fiscal plans rather than of individual fiscal shocks. The simulation of the fiscal plans adopted by 16 OECD countries over a 30-year period supports the hypothesis that the...
