The rate of teen smoking rose by one-third in the 1990s. Cruber and Zinman explore four aspects of the decision by youths to smoke. They find that smoking participation is not simply concentrated among the most disadvantaged youth; indeed, increasingly over time youth smoking is taking place among white, suburban youth who have college-educated parents and good grades. The authors also show that neither changes in demographic characteristics nor new attitudes toward smoking can explain the striking increase in smoking rates in the 1990s. Price is a powerful determinant of smoking for high school seniors, though. Analysis of data for the 1991-7 period suggests that the drop in cigarette prices in the early 1990s can explain 30 percent of the subsequent upward smoking trend. However, price is not important for younger teens, although restrictions on access to cigarette purchases may lower the quantity that younger teens smoke. Finally, the authors demonstrate an important link between smoking as a youth and smoking later in life. This suggests that policies that stop youth from smoking can have long-lasting effects, and raises potential concerns about the long-run implications of the current rise in youth smoking.

Traffic accidents are the leading cause of deaths among young adults, but teen traffic safety has improved considerably in recent years. Between 1979 and 1997, the teen traffic fatality rate has fallen by almost 25 percent, much more than among older drivers. According to Dee and Evans, these numbers actually understate the true improvements in safety, because teen driving has increased considerably over this period. Nearly all of the drop in the fatality rate can be explained by a large reduction in drunk driving among teens, they find. …
