This article is a contribution to the debate on the determinants and e
conomic effects of military expenditure in less-developed economies. R
ecent empirical work has suggested that there is much to be gained fro
m analysing groups of relatively homogeneous countries, and to this en
d it focuses on a sample of thirteen Sub-Saharan African countries ove
r the period from 1967 to 1985. The econometric analysis uses data for
the group of countries as a whole, a cross-sectional analysis of the
country averages, and an analysis of the pooled country data. As regar
ds the determinants of military spending, the results suggest that eco
nomic factors play an important role in determining the level of milit
ary burden across countries and over time for the sample as a whole. W
hen the data are pooled, strategic factors such as wars, the size of t
he army and inertia become important. In a time-series analysis, milit
ary expenditure is also found to have a negative effect on economic de
velopment for the countries as a whole, through its negative indirect
effects on human resource accumulation, investment allocations and the
balance of payments. While this result is not found across countries,
or when the data are pooled, the results still imply that there is no
significant positive effect of military burden on economic growth. To
gether, these results show the value of attempting to capture both tim
e-series and cross-sectional effects when analysing the determinants a
nd economic effects of military spending and the value of dealing with
relatively homogeneous groups of countries.
