This article evaluates the poverty alleviation effect of international
aid provided by Japan, the United Kingdom, the United States, the Dev
elopment Assistance Committee members, and multilateral organizations.
A consistent poverty evaluation framework together with head count ra
tio data comparable across countries is employed. Results indicate tha
t aid expansion by the government of Japan is relatively inefficient a
nd ineffective in terms of poverty alleviation. On the other hand, the
UK and multilateral institutions might have been most effective at th
e margin among the donors considered. Results for US aid indicate that
major revisions of the amounts disbursed under its Economic Support F
und are required to improve the efficiency and marginal effectiveness
of US aid in terms of poverty alleviation. However, the change in meas
ures between 1985 and 1990 suggests a decline in poverty alleviation e
ffectiveness for Japan and the UK, and a increase for the US.
