Frequent exercise boosts wages, but the increase is much more pronounced for women than for men, according to Vasilios D. Kosteas of Cleveland State University. Women who exercise frequently earn 11.9% more, on average, than women who don’t—a premium that’s approximately equal to the effect of 1.8 additional years’ schooling. For men, the wage benefit of frequent exercise is 6.7%, equivalent to about 1.3 years more school, Kosteas says. The findings are consistent with the hypothesis that beauty and fitness matter more for women’s wages than for men’s.
