The author argues that macroeconomic evaluations of the impact of aid
still lack an established methodology. It is mentioned that when asses
sing the impact of economic reform programmes, the authors of the vari
ous evaluations have encountered a series of problems such as the time
span which has often been too short. Very few evaluations address the
issue of the extent of 'ownership' of the respective adjustment progr
ammes and the degree of domestic political credibility Potential criti
cal areas that might be addressed in evaluations could include the fol
lowing items: incentive problems related to the high marginal tax on g
ood performance implicit in the 'financing gap' approach; the danger o
f a soft budget, constraint being introduced by benevolent donors; the
danger of programme aid being used to bail out bad performers year af
ter year; and the multiple roles played by the IFI as preferred credit
ors, major macroeconomic advisers and coordinators of part of the bila
teral aid.
