We develop a model of individual prosecutors (and teams of prosecutors) to address the incentives for the suppression of exculpatory evidence. Our model assumes that each individual prosecutor trades off a desire for career advancement (by winning a case) and a disutility for knowingly...

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...

Empirical studies have found that increasing the probability of punishment has a greater effect on crime than the severity of punishment. This note explains this as the result of criminals having imperfect information on their criminal ability. As they commit crimes, they update their estimates...

This paper provides a simple model of corruption dynamics with the ratchet effect. Corrupt officials have ex post the incentive to price discriminate entrepreneurs based on the entry decisions made in an earlier period. The inability of government officials to commit to future money demands...

This paper provides a simple model of repeated extortion. In particular, we ask whether corrupt government officials' ex post opportunism to demand more once entrepreneurs have made sunk investments entails further distortion in resource allocations. We show that the inability of government...

The economic literature on crime and punishment focuses on the trade-off between probability and severity of punishment, and suggests that detection probability and fines are substitutes. In this paper it is shown that, in presence of substantial underdeterrence caused by costly detection and...
