Marriage as a Mechanism of Internalizing Externalities: A Case of Smoking

Abstract

Abstract With the view of marriage as a legal institution to internalize externalities, I examine the effect of marriage on smoking. From analyzing the data of Panel Study of Income Dynamics, I found that unmarried individuals are more likely to smoke by 4.9% point than married individuals with stronger impact on females. The long-run impact of marriage also shows that the unmarried individuals smoke more than married individuals but some of its positive impact diminishes within two years. These results on the whole imply that marriage internalizes the negative externalities of smoking and thus leads smokers to reduce smoking.
