Marital conflicts can have negative welfare consequences. In this pape
r we use an equivalence scale approach to analyze the household labor
supply and welfare effects of marital conflict. It might be assumed th
at there is a simultaneous relation between labor supply and marital c
onflict: increased labor force participation of women may increase mar
ital conflict, while spouses may adjust their labor supply because of
marital conflict. The empirical results show that such a simultaneous
relation exists. Women who participate in the labor market have more c
onflicts about the division of household tasks and the care of childre
n than non-participating women. On the other hand, marital conflicts c
ause women to reduce their labor supply. Finally, it is found that the
welfare losses due to marital conflict are substantial.
