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 survey presents the various methods to estimate the size of the shadow economy, their strengths and weaknesses and the estimation results. The purpose of the survey is threefold. Firstly, it demonstrates that no ideal method to estimate the size and development of the shadow economy exists....

We estimate the "incapacitation effect" on crime using variation in Italian prison population driven by eight collective pardons passed between 1962 and 1995. The prison releases are sudden – within one day –, very large – up to 35 percent of the entire prison population – and happen...

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...

The monopoly position of the public bureaucracy in providing public services allows government employees to acquire rents. Those rents can involve higher wages, monetary and non-monetary fringe benefits (e.g. pensions and staffing), and/or bribes. We propose a direct measure to capture the total...

This paper explores the experience of information sharing, coordination, and integration of actions of the Civil and Military Polices in the state of Minas Gerais, Brazil, in the context of the IGESP program. The IGESP is based on the introduction of information management systems and...

This paper contributes to the literature on specific deterrence by addressing the issue of selecting adolescents into adult and juvenile law systems. In Germany, different from the U.S. and most other countries, turning a critical cutoff age does not cause a sharp discontinuity from juvenile to...

We examine the consequences, of integrating large minorities into productivity-relevant majority ethno-linguistic norms, for distribution, ethnic conflict and crime. We develop a two-community model where such assimilation generates social gains by: (a) facilitating economic interaction, and (b)...

This paper argues that UN military interventions are geographically biased. For every 1,000 kilometers of distance from the three Western permanent UNSC members (France, UK, US), the probability of a UN military intervention decreases by 4 percent. We are able to rule out several alternative...

Turf wars commonly occur in environments where competition undermines collaboration. We develop a game theoretic model and experimental test of turf wars. The model explores how team production incentives ex post affect team formation decisions ex ante. In the game, one agent decides whether to...
