(HealthDay News) -- A new study finds that men are more likely to cheat if their income is much lower than what their wife or female partner makes, while women are more likely to fool around if they make more than their husband or male partner.

The findings suggest that disparities in moneymaking play a significant role in infidelity, at least among the young couples they studied.

"With women, they were less likely to engage in infidelity the less money they make relative to their husband," said study author Christin Munsch. "But for men, the less money you make relative to your spouse, the more likely you are to engage in infidelity."

Munsch, a graduate student at Cornell University, said she came up with the idea of studying the effects of income on infidelity after hearing from a friend who has cheated on his partner. He told Munsch that "she made all the money, she had all the friends, and he'd moved up there to be with her. He felt completely powerless."
