We develop a political-economic model of foreign aid allocation. Each ethni
c group in the donor country lobbies the government to allocate mole aid to
its country of origin, and the government accepts political contributions
from lobby groups. Initial per-capita income of the recipients and those of
the ethnic groups are shown to be important determinants of the solution o
f the political equilibrium. We also examine the effects of changes in the:
degree of corruption, aid fatigue, and ethnic composition, in the donor co
untry on the allocation of aid.
