Counterpart funds generated by programme aid do not provide real resou
rces over and above the commodities or foreign exchange transferred as
aid: they represent the tail not the tiger. However, donor policy has
evolved to recognise this fact and now focuses less on specific ear-m
arking of counterpart Funds, more on the overall quality ol the budget
process. This development opens up new and more interesting possibili
ties for evaluating the effectiveness and efficiency of counterpart fu
nd management. The paper proposes performance criteria, especially for
bilateral donors supporting the budget through counterpart fund gener
ation. Existing evaluations do not generally provide information about
whether these standards have been satisfied. This is a task for the f
uture.
