CROSS-COUNTRY ANALYSIS*

ABSTRACT
Violence rates differ dramatically across countries. A widely held view is that
these differences reflect differences in gun control and/or gun availability, and certain
pieces of evidence appear consistent with this hypothesis. A more detailed exami-
nation of this evidence suggests that the role of gun control/availability is not com-
pelling. This more detailed examination, however, does not provide an alternative
explanation for cross-country differences in violence. This paper suggests that dif-
ferences in the enforcement of drug prohibition are an important factor in explaining
differences in violence rates across countries. To determine the validity of this hy-
pothesis, the paper examines data on homicide rates, drug prohibition enforcement,
and gun control policy for a broad range of countries. The results suggest a role for
drug prohibition enforcement in explaining cross-country differences in violence, and
they provide an alternative explanation for some of the apparent effects of gun control/
availability on violence rates.
I. INTRODUCTION
VIOLENCE rates differ dramatically across countries. Each year there is
roughly one homicide per 100,000 persons in England or Japan but nine per
100,000 in the United States. Moreover, these differences have persisted over
long time periods; they suggest fundamental differences in the determinants
of violence across countries, not just transitory variation.
A widely held view is that these differences result from differences in gun
control and/or gun availability, and certain pieces of evidence appear con-
sistent with this hypothesis.' Most notably, England and Japan have restrictive
