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 consider a voluntary contributions game, in which players may punish others after contributions are made and observed. The productivity of contributions, as captured in the marginal-per-capita return, differs among individuals, so that there are two types: high and low productivity. Every two...

Victorious alliances often fight about the spoils of war. This paper presents an experiment on the determinants of whether alliances break up and fight internally after having defeated a joint enemy. First, if peaceful sharing yields an asymmetric rent distribution, this increases the likelihood...

Democratic societies are challenged by various violent and organized groups, be they terrorists, gangs or organized hooligans. In exchange for offering an identity, leaders in such groups typically require members to be violent. We introduce a simple model to capture these stylized facts, and...

The threat of overthrow stabilizes a constitution because it disciplines the elites. This is the main rationale behind rights to resistance. In this paper, we test this conjecture experimentally. We model a society in which players can produce wealth by solving a coordination problem....

We study the external validity of a standard laboratory measure of cheating. The results show that cheating in the lab significantly predicts classroom misbehavior in middle and high school students.

We explore the individual and joint explanatory power of concepts from economics, psychology, and criminology for criminal behavior. More precisely, we consider risk and time preferences, personality traits from psychology (Big Five and locus of control), and a self-control scale from...

In economic models, risk and social preferences are major determinants of criminal behavior. In criminology, low self-control is considered a fundamental cause of crime. Relating the arguments from both disciplines, this paper studies the relationship between self-control and both risk and...

This paper argues that the Economics of Crime concentrates too much on punishment as a policy to fight crime, which is unwise for several reasons. There are important instances in which punishment simply cannot reduce crime. Several feasible alternatives to punishment exist, such as offering...
