Using state-level data for the period 1990 through 2007, we estimate the effect of legalizing medical marijuana on suicide rates. Our results suggest that the passage of a medical marijuana law is associated with an almost 5 percent reduction in the total suicide rate, an 11 percent reduction in...

Occupational licensing is intended to protect consumers. Whether it does so is an important, but unanswered, question. Exploiting variation across states and municipalities in the timing and details of midwifery laws introduced during the period 1900-1940, and using a rich data set that we...
