This article examines empirically the secular growth of the government
sector in the United States since World War II. Like a similar study
of Canadian federal government expenditures, this article also conside
rs both the economic and political dimensions of the issue, but it inc
orporates additional factors peculiar to the United States, such as mi
litary spending and the Reagan era. The study finds that: (1) Military
spending and real income growth are the primary determinants of the g
rowth of government expenditures' share of GNP; (2) To a lesser extent
, perceived economic problems, government employment, the proportion o
f the elderly population, and elite preferences also play some part in
explaining governmental growth in the United States; and (3) While th
e Reagan presidency had some impact on the purchases of government goo
ds and services, it had little effect in restraining overall governmen
t expansion.
