So What Did You Do Last Night? The Economics of Infidelity

Anyone married to an unhappy 55-year-old man who lives in the city could think about being suspicious that their husband may be having an affair.

Likewise, for anyone married to an unhappy 45-year-old woman who doesn't have a college education and regularly skips church may need to raise the question, according to a recently released University of New Hampshire study.

Those composite descriptions are based on a slew of demographic and economic factors that determine the likelihood someone will have an affair, the study found.

Bruce Elmslie, an economics professor at the UNH Whittemore School of Business and Economics, and Edinaldo Tebaldi, assistant professor of economics at Bryant University, jointly compiled the study, titled "So What Did You Do Last Night? The Economics of Infidelity."
