A number of states passed legislation in the 1990s requiring youths to wear helmets when riding bicycles. The effect of this legislation on bicycling fatalities is examined by subjecting data from the Fatality Analysis Reporting System to a panel analysis, using a control-group methodology. A...

Among U.S. drivers involved in fatal accidents, blood alcohol concentration conditional on drinking is static. Thus the dynamics of drunk driving can be described using the fraction of accident-involved drivers who have been drinking (HBD). Changes in this variable imply significant reductions...

"By 1998, all states had passed laws lowering the legal blood alcohol content for drivers under 21 to effectively zero. Theory shows these laws have ambiguous effects on overall fatalities and economic efficiency, and the data show they have little effect on driver behavior. A panel analysis of...
