Using individual data on persons arrested in the Medellin Metropolitan Area, this paper assesses whether the change in punishment at age 18, mandated by law, has a deterrent effect on arrests. No deterrent effect was found on index, violent or property crimes, but a deterrence effect was found...

This paper estimates the effect of local labor market conditions on crime in a developing country with high crime rates. Contrary to the previous literature, which has focused exclusively on developed countries with relatively low crime rates, we find that labor market conditions have a strong...

In this paper, we propose a new approach to the empirical study of the relationships among schooling, youth employment and youth crime which provides a comprehensive analysis of the dynamic interactions among these choices and exposure to the criminal justice system. The empirical framework...

This paper studies the causal impact of court deferrals, a legal strategy to help defendants avoid a felony conviction record, on the future criminal and labor market outcomes of first-time felony drug offenders. To accomplish this, we exploit two natural experiments in Harris County, Texas, in...

Understanding whether, and in what situations, time spent in prison is criminogenic or preventive has proven challenging due to data availability and correlated unobservables. This paper overcomes these challenges in the context of Norway’s criminal justice system, offering new insights into...

Punishment has been shown to be an effective reinforcement mechanism. Intentional or not, punishment will likely generate spillover effects that extend beyond one’s immediate decision environment, and these spillovers are not as well understood. We seek to understand these secondary spillover...
