Smoking and alcohol use are widespread among adolescents in the US and are linked to negative socioeconomic effects.While existing research has separately looked at the dynamic choice and the social interactions that shape adolescent risky behaviours, this column considers both components in a dynamic social interactions model. Looking at alcohol and smoking use in a school environment, it finds that addiction and peer effects are more than twice as important as the effect of individual preferences in shaping risky behaviour and that students take into account the amount of time they have left in the school system.

Sicker consumers tend to exhibit higher demand for health insurance, which drives up costs. This column argues that this adverse selection takes place along two margins: whether to buy insurance at all and how much coverage to buy, It develops a new framework that incorporates both selection margins, and shows that policies aimed at addressing one margin can often exacerbate selection along the other. It is therefore vital for optimal policy to consider both margins simultaneously.

Higher public risk perception increased patent applications and the rate of new product innovation, even without changes in liability or regulation.
