Smoking is one of our favorite topics on this blog -- from the ethics of not hiring smokers to the use of commitment devices to quit. A new NBER paper (gated) by Kerry Anne McGeary looks at smoking in marriages. It finds that one spouse quitting causes the other to quit, through bargaining:
Previous research studying the correlation in smoking behavior between spouses has discounted the role of bargaining or learning. Using the Health and Retirement Study (HRS), which contains information on smoking cessation and spouse’s preferences, this paper presents an essential investigation of the importance of spousal bargaining or learning on the decision to cease smoking. We find, regardless of gender, when one member of [a] couple ceases smoking this induces the other member to cease smoking through bargaining. Further, we find females demonstrate either altruistic behavior toward a spouse, who has suffered a health shock, or learning from their spouse’s health shock.
