However, the majority of the gender gap in labor supply elasticities is driven by across firm sorting rather than within firm differences, a feature predicted in the search theory literature, but which has not been previously documented. The gender differential in supply elasticities leads to 3.3% lower earnings for women. Roughly 60% of the elasticity differential can be explained by marriage and children penalties faced by women but not men. %K discrimination %K monopsony
