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...

The paper explores the fit properties of a class of multivariate Lévy processes, which are characterized as time-changed correlated Brownian motions. The time-change has a common and an idiosyncratic component, to re ect the properties of trade, which it represents. The resulting process may...

This paper constructs a class of multivariate Gaussian marked Poisson processes to model asset returns. The model proposed accommodates the cross section properties of trades, allows for returns to be correlated conditional on trading activity, and preserves the economic intuition of normality...

The traditional multivariate Lévy process constructed by subordinating a Brownian motion through a univariate subordinator presents a number of drawbacks, including the lack of independence and a limited range of dependence. In order to face these, we investigate multivariate subordination,...

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...

Time-changed Brownian motions are extensively applied as mathematical models for asset returns in Finance. Time change is interpreted as a switch to trade-related business time, different from calendar time. Time-changed Brownian motions can be generated by infinite divisible normal mixtures....
