This paper analyzes how enforcement along the U.S.-Mexican border has affected the market for migrant smugglers. Using a unique dataset that links border crossing histories from illegal Mexican migrants to aggregate enforcement and punishment statistics, we find that the effect of enforcement on...

We study a theoretical general equilibrium environment in which the only activity of interest is armed robbery. Agents choose whether to be citizens or robbers, and whether to purchase handguns. Armed citizens can protect themselves from robbery but any armed agent runs the risk of accidentally...

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...

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...

The rising trends both in drug addiction and crime rates are of major public concern in Germany. Surprisingly, the economic theory of crime seems to ignore the drugs/crime nexus, whereas the criminological lit- erature considers illicit drug use a main reason of criminal activities. This paper...

Delinquents are embedded in a network of relationships. Social ties among delinquents are modeled by means of a graph where delinquents compete for a booty and benefit from local interactions with their neighbors. Each delinquent decides in a non-cooperative way how much delinquency effort he...

This paper offers a new argument for why a more aggressive enforcement of minor offenses (zero-tolerance) may yield a double dividend in that it reduces both minor offenses and more severe crime. We develop a model of criminal subcultures in which people gain social status among their peers for...

Obwohl das Verhaltensmodell des homo oeconomicus sowohl der Rechtswissenschaft wie der Rechtspolitik bei Fragen der Rechtsfolgenabschätzung von großem Nutzen sein kann, wird dessen Akzeptanz erschwert, weil bei ihm strikte Rationalität unterstellt wird. Im Beitrag wird unter Rückgriff auf...

Our study is based on the traditional Becker-Ehrlich deterrence model, but we analyse the model in the face of currently discussed factors of crime like demographic changes, youth-unemployment and income inequality. We use a panel of the German Laender (states) that allows us to exploit...
