In this paper we estimate the effects of expanding access to substance-abuse treatment on local crime. We do so using an identification strategy that leverages variation driven by substance-abuse-treatment facility openings and closings measured at the county level. The results indicate that...

This paper estimates the effects of temporary driver's license suspensions on driving behavior. A little known rule in the German traffic penalty catalogue maintains that drivers who commit a series of speeding transgressions within 365 days should have their license suspended for one month. My...

This paper leverages a discontinuity in legal access to alcohol at age 16 to estimate its impacts on teenage drinking and crime in Germany, a country with very high consumption levels. Using detailed survey data and administrative crime records from 2005 to 2015, I detect considerable increases...

Many rights are conferred on Dutch youth at ages 16 and 18. Using national register data for all reported victimizations, we find sharp and discontinuous increases in victimization rates at these ages: about 13% for both genders at 16 and 9% (15%) for males (females) at 18. These results are...

This paper evaluates the impact of a sudden and unexpected nation-wide alcohol sales ban in South Africa. We find that this policy causally reduced injury-induced mortality in the country by at least 14% during the five weeks of the ban. We argue that this estimate constitutes a lower bound on...

This research provides the first evidence on the impacts of waiting times for treatment for a substance use disorder (SUD). Using rich linked administrative information from Norway, we study the impact of waiting time on health-care utilization, employment and crime for patients who enter...

Reducing drink drive limits is generally regarded an effective strategy to save lives on the road. Using several new administrative data sources, we evaluate the effect of a stricter limit introduced in Scotland in 2014. This reduction had no effect on drink driving and road collisions....
