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 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...

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...

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...

This paper studies whether structural properties of friendship networks affect individual outcomes in education and crime. We first develop a model that shows that, at the Nash equilibrium, the outcome of each individual embedded in a network is proportional to her Bonacich centrality measure....

Delinquents are embedded in a network of relationships. Social ties among delinquents are modelled 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...

The first half of the twentieth century saw rapid improvements in the health and height of British children. Average height and health can be related to infant mortality through a positive selection effect and a negative scarring effect. Examining town-level panel data on the heights of school...

Increases in human stature are seen as a key indicator of improvement in the average health of populations. The literature associates stature with a variety of socioeconomic variables, and much of the focus is on the nineteenth century and on the last 50 years. In this paper I present and...
