Based on unique data on individual bank robberies perpetrated in Italy between 2005 and 2007, this paper estimates the distribution of criminals' disutility of jail. The identification rests on the money versus risk trade-off criminals face when deciding whether to stay an additional minute...

Using unique data on criminal profiles of 800 US Mafia members active in the 50s and 60s and on their connections within the Cosa Nostra network we analyze how the geometry of criminal ties between mobsters depends on family ties, community roots and ties, legal and illegal activities. We...

Using declassified Federal Bureau of Narcotics records on 800 US Mafia mem- bers active in the 1950s and 1960s, and on their connections within the organized crime network, I estimate network effects on gangsters’ economic status. Lacking information on criminal proceeds, I measure economic...

We define and investigate a new class of measure-valued Markov chains by resorting to ideas formulated in Bayesian nonparametrics related to the Dirichlet process and the Gibbs sampler. Dependent random probability measures in this class are shown to be stationary and ergodic with respect to the...

The paper proposes a new nonparametric prior for two-dimensional vectors of survival functions (S1,S2). The definition we introduce is based on the notion of Lévy copula and it will be used to model, in a nonparametric Bayesian framework, two-sample survival data. Such an application will yield...

A Bayesian nonparametric methodology has been recently proposed in order to deal with the issue of prediction within species sampling problems. Such problems concern the evaluation, conditional on a sample of size n, of the species variety featured by an additional sample of size m. Genomic...

A random distribution function on the positive real line which belongs to the class of neutral to the right priors is defined. It corresponds to the superposition of independent beta processes at the cumulative hazard level. The definition is constructive and starts with a discrete time process...

Incarceration of criminals reduces crime through two main channels, deterrence and incapac- itation. Because of a simultaneity between crime and incarceration–arrested criminals increase the prison population–it is difficult to measure these effects. This paper estimates the incapaci- tation...
