Exercise and Earnings The Effect of Exercise on Earnings: Evidence from the NLSY

This paper investigates whether engaging in regular exercise leads to higher earnings in the labor market. While there has been a recent surge of interest by economists on the issue of obesity, relatively little attention has been given to the economic effects of regular physical activity apart from its impact on body composition. I find that engaging in regular exercise yields a six to ten percent wage increase. The results also show that while even moderate exercise yields a positive earnings effect, frequent exercise generates an even larger impact. These findings are fairly robust to a variety of estimation techniques, including instrumental variables via two-stage least squares and propensity score matching.
