The trade-off between the immediate returns from committing a crime and the future costs of punishment depends on an offender's time discounting. We exploit quasi-experimental variation in sentence length generated by a large collective pardon in Italy and provide non-parametric evidence on the...

Research in criminology has shown that the perceived risk of apprehension often differs substantially from the true level. To account for this insight, we extend the standard economic model of law enforcement (Becker, 1968) by considering two types of offenders, sophisticates and naïves. The...

We focus in this paper on the effects of court errors on the optimal sharing of liability between firms and financiers, as an environmental policy instrument. Using a structural model of the interactions between firms, financial institutions, governments and courts we show, through numerical...

When a principal’s monitoring information is private (non-verifiable), the agent should be concerned that the principal could misrepresent the information to reduce the agent’s wage or collect a monetary penalty. Restoring credibility may lead to an extreme waste of resources - the so-called...

Using an identification strategy based on random assignment of refugees to different municipalities in Denmark between 1986 and 1998, we find strong evidence that gang crime rates in the neighbourhood at assignment increase the probability of boys to commit crimes before the age of 19, and that...

We examine the extent to which DNA exonerations can reveal whether wrongful conviction rates differ across races. We show that under a wide-range of assumptions regarding possible explicit or implicit racial biases in the DNA exoneration process (including no bias), our results suggest the...

We investigate one possible explanation for observed rates of corrupt behavior namely that individual decision makers who frequently engage in illegal actions may underestimate the overall probability of being caught. This might in particular be true for petty corruption where small amounts of...

This paper offers a new argument for why a more aggressive enforcement of minor offenses ('zero-tolerance') may yield a double dividend in that it reduces both minor offenses and more severe crime. We develop a model of criminal subcultures in which people gain social status among their peers...

This paper tests predictions of a structural, augmented supply-of-offenders model regarding the relative effects of police, public prosecution and courts, respectively, on crime. Using detailed data on the different stages of the criminal prosecution process in Germany, empirical evidence...

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,...
