Although researchers have recently made some progress in explaining th
e outputs of the US economic aid decision-making process, their effort
s to explain the allocation of US military aid have been rather disapp
ointing. In this article, we follow previous studies that have assumed
a two-stage process leading up to the allocation of military aid, whi
le making three significant improvements over those efforts. First we
employ a better model, including a variety of political, strategic, ec
onomic, and humanitarian variables we hypothesize to be related to the
allocation of military aid. Second, we solve the 'low n' difficulty t
hat plagued previous research, by employing an extensive dataset that
covers a global sample of countries covering the 1983-8 period. And th
ird, unlike previous research where a two-stage process has been assum
ed, we employ a methodology that solves the difficulties associated wi
th selection bias, which arises when two interrelated decisions are mo
deled separately. As a result of these improvements our results are mu
ch stronger than those of previous studies. We find that strategic, po
litical, and economic interests, as well as human rights concerns and
economic development, have been considered in the US military aid deci
sion-making process.
