Reexamining the Economics of Marital Infidelity

Abstract

This study utilizes data from the National Youth Survey to reevaluate key conclusions made by Fair (1978). While Fair (1978) used data collected from mail-in surveys, the National Youth Survey was collected using standard probability techniques. This paper also extends Fair (1978), by including an explicit variable for wage rate. While this study supports some of Fair's empirical findings, other estimates contradict Fair in several key ways. For example, this paper finds that the coefficients of occupation and education are both statistically significant but the signs are opposite to those in Fair (1978). An even more noteworthy contradiction is the negative relationship between years of marriage and infidelity; this suggests that marriage longevity is positively related to that of match quality of the relationship.extramarital affairs, marriage, wages, match quality
