We hypothesize the failure of government to protect the rights of individuals from violence committed by youths has led to the formation of youth gangs as protective agencies. Our theory predicts an opposite direction of causality between gang activity and violent crime than is widely accepted....

Empirical evidence reveals that unemployment tends to increase property crime but that it has no effect on violent crime. To explain these facts, we examine a model of criminal gangs and suggest that there is a substitution effect between property crime and violent crime at work. In the model,...

This paper develops a model of the war against illegal drugs in both producer and consumer countries. The paper studies the trade-off faced by the government of the drug consumer country between prevention policies (aimed at reducing the demand for drugs) and enforcement policies (aimed at...

We test whether immigrants are more prone to support terror than natives because of lower opportunity costs, using the international World Values Survey data. We show that, in general, economically, politically and socially non-integrated persons are more likely to accept using violence for...

We analyse property crime in an economy composed of a large number of heterogeneous individuals who need to protect themselves. The crime equilibrium is modeled as a free-access equilibrium in which the match between criminals and victims equates the average returns to crime. The supply and...

This paper analyzes the deterrent effects of both border patrol agents and increased U.S.-Mexico fencing on reported crime rates in U.S. cities located along the border, between 1992 and 2017. We find that, for cities along the U.S.-Mexico border, increases in the number of border patrol agents,...

Most studies examining the impact of migrants on crime rates in hosting populations are in the context of economic migrants in developed countries. However, we know much less about the crime impact of refugees in low- and middle-income countriesâ whose numbers are increasing worldwide. This...

We evaluate the effect of perhaps the largest exogenous decline in a state's incarceration rate in U.S. history on local crime rates. We assess the effects of a recent reform in California that caused a sharp and permanent reduction in the state's incarceration rate. We exploit the large...
