In mid-1995, a government effort to reduce the supply of methamphetamine precursors successfully disrupted the methamphetamine market and interrupted a trajectory of increasing usage. The price of methamphetamine tripled and purity declined from 90 percent to 20 percent. Simultaneously,...

We provide a critical review of research in economics that has examined causal relationships between alcohol use and crime. We lay out several causal pathways through which alcohol regulation and alcohol consumption may affect crime, including: direct pharmacological effects on aggression,...

In this paper we estimate the effect of class attendance on exam performance by implementing a policy in three large economics classes that required students scoring below the median on the midterm exam to attend class. This policy generated a large discontinuity in the rate of post-midterm...

We estimate the effect of alcohol consumption on mortality using the minimum drinking age in a regression discontinuity design. We find large and immediate increases in drinking at age 21, including a 21 percent increase in recent drinking days. We also find a discrete 9 percent increase in the...

A substantial economics literature documents that tighter alcohol controls reduce alcohol related harms, but far less is known about mechanisms. We use the universe of Canadian mortality records to document that Canada's Minimum Legal Drinking Age (MLDA) significantly reduces mortality rates of...

Previous research has established an association between air pollution and adult mortality. However, studies utilizing short-term fluctuations in pollution may detect mortality changes among the already ill or dying, while prospective cohort studies, which utilize geographic differences in...
