In attempting to identify institutional factors that influence a natio
n's per capita growth rate scholarship in political science has focuse
d almost exclusively on differences in political regimes. This article
argues that if we are interested in understanding why some nations gr
ow faster than others, then we must redirect our inquiry and focus on
property rights. Using new measures for property rights protection and
democracy, and building on an endogenous growth model, this study pre
sents the first approximation of the relationship between property rig
hts, democracy, and economic growth. These relationships are tested us
ing cross-national panel data from 1960-90. The evidence supports two
conclusions: (1) economies of nations that protect property rights gro
w more rapidly than those of nations that do not protect property righ
ts; and (2) the nature of a political regime influences economic growt
h indirectly through its commitment to property rights.
