No-fault divorce laws and the labor supply of women with and without children

We use a difference-in-difference-in-difference estimator to compare changes in labor force participation, weeks, and hours of work associated with no-fault divorce laws, allowing for differential responses for married women with and without children. Although other research has found that the labor supply of women in general does not respond to no-fault divorce laws, we find that no-fault divorce laws are associated with increases in the labor supply of married mothers relative to married nonmothers, even after controlling for changes in female labor supply, in states without no-fault divorce laws and for property, division rules associated with the laws.
