Criminals are embedded in a network of relationships. Social ties among criminals are modelled by means of a graph where criminals compete for a bounty and benefit from local interactions with their neighbours. Each criminal decides in a non-cooperative way how much crime effort they will exert....

We highlight the role of commuting cost, location and housing market in crime decision. By assuming that all crimes are committed in the central business district and that criminals create both positive and negative externalities to each other, we find that high wages or large levels of police...

We propose a simple conformism model that explains how parental education and peer pressure impact on criminal activities. We then test the model using the U.S. National Longitudinal Survey of Adolescent Health (AddHealth), which contains unique information on friendship relationships among...

We develop a model in which delinquents compete with each other in criminal activities but may benefit from being friends with other criminals (by learning and acquiring proper know-how in the crime business). We first study the Nash equilibrium of this game by taking the social network...

The aim of this paper is to show that both location and stereotypical racial beliefs matter for explaining the high criminality rate among blacks in cities. In our model, blacks and whites are identical in all respects. However, if, for not economic but extrinsic reasons, everybody (including...

Policy towards asylum seekers has been a controversial topic for more than a decade. Rising numbers of asylum applications have been met with ever-tougher policies to deter them. Following a period of policy harmonisation, the EU has reached a crucial stage in the development of a new Common...

We analyse an oligopoly model in which differentiated criminal organizations compete on criminal activities and engage in corruption to avoid punishment. When law enforcers are sufficiently well-paid, difficult to bribe and corruption detection highly probable, we show that increasing policing...

This Paper aims to explain the spatial variations of crime, both between and within cities. Two types of mechanisms are put forward: social interactions that stipulate that an individual is more likely to commit crime if his peers commit than if they do not commit crime; and distance to jobs that...

Australia’s policies towards asylum seekers hit the headlines when it refused to admit those aboard the Tampa in September 2001. This tough stance and the raft of legislation that followed became known as Australia’s ‘Pacific Solution’. It was clearly intended to deter those who might...

This paper analyses the interplay between social structure and information exchange in two competing activities, crime and labour. We consider a dynamic model in which individuals belong to mutually exclusive two-person groups, referred to as dyads. There are multiple equilibria. If jobs are...
