Taxation and Household Labour Supply

Abstract

We evaluate reforms to the U.S. tax system in a life cycle set-up with heterogeneous married and single households and with an operative extensive margin in labour supply. We restrict our model with observations on gender and skill premia, labour-force participation of married females across skill groups, children, and the structure of marital sorting. We concentrate on two revenue-neutral tax reforms: a proportional income tax and a reform in which married individuals file taxes separately (<it>separate filing</it>). Our findings indicate that tax reforms are accompanied by large increases in labour supply that differ across demographic groups, with the bulk of the increase coming from married females. Under a proportional income tax reform, married females account for more than 50% of the changes in hours across steady states, while under separate filing reform, married females account for all the change in hours.
