This study considers the effect that judicial and police efficiency exercised on crime in 25 of the 33 political-administrative divisions in Colombia during the period 2000-2011. Specifically, the study seeks to determine whether the reduction of crime was the result of increases in the cost of...

We study peer effects in crime by analyzing co-offending networks. We first provide a credible estimate of peer effects in these networks equal to 0.17. This estimate implies a social multiplier of 1.2 for those individuals linked to only one co-offender and a social multiplier of 2 for those...

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,...

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...

A significant number of women experience physical or sexual violence throughout their lives, with a considerable portion of such incidents occurring in public spaces. Harmful social norms emphasizing men's power over women have been highlighted as one crucial culprit. We study a public festivity...

We provide evidence about voters' response to crime control policies. We exploit a natural experiment arising from the Italian 2006 collective pardon releasing about one third of the prison population. The pardon created idiosyncratic incentives to recidivate across released individuals and...

This study analyses voters' response to criminal justice policies by exploiting a natural experiment. The 2006 Italian Collective Pardon Bill, designed and promoted by the incumbent center-left (CL) coalition, unexpectedly released about one-third of the prison population, creating idiosyncratic...

We study how news coverage of immigrant criminality impacted municipality-level votes in the November 2009 “minaret ban” referendum in Switzerland. The campaign, successfully led by the populist Swiss People's Party, played aggressively on fears of Muslim immigration and linked Islam with...
