Mens Sana in Corpore Sano! The hiring premium for physical versus mental exercise in different occupations

We investigate the impact of participation in physical and mental exercise activities on hirability. To this end, an audit experiment is conducted in which we send 2184 fictitious applications of young job seekers to real job vacancies. On average, the estimated effect of both physical and mental exercise activities is small and statistically nonsignificant. However, the effect of participation in any exercise activity is significantly positive for jobs combining low cognitive with low physical demands. These findings are not consistent with the common consideration of physical exercise activities being used by employers as signals of physical fitness and appearance.
