8.1 percent for women (Kenkel 1993). Even larger reductions of 12.6 percent among men and 21.1 percent among women would occur among people ages 21 years and younger. A study using self-reported data on involvement in traffic crashes obtained during the 1982 and 1989 Monitoring the Future surveys concluded that a policy adjusting the Federal beer tax for the inflation rate since 1951 would reduce the probability of nonfatal traffic crashes by almost 6 percent for both men and women (Chaloupka and Laixuthai 1997).
