About Me

I am a final-year PhD student in economics at the Department of Economics, University of Gothenburg. My research interests lie at the (pretty crowded) intersection of labor economics, public economics, family economics and economics of education.

Working Paper

Withheld from Working More? Withholding Taxes and the Labor Supply of Married Women (with Lenard Simon and Jakob Wegmann)

Media coverage (in German): FAZ, Südwest Presse
Non-technical summary (in German): ifo Schnelldienst pp. 23-27

Abstract:
The impact of withholding taxes on labor supply has so far been neglected in the analysis of the optimal design of income taxation systems. We investigate their importance in the context of married couples in Germany. In a first step, we document with the help of a survey that less than 20% of the interviewed married individuals understand that withholding taxes are tax prepayments which are fully credited against the final income tax and, therefore, do not determine the income tax burden. Making use of a reform that decreased the withholding tax burden for some married women more than for others, while inducing no differences in income taxes, allows us to then estimate the elasticity of labor income with respect to the withholding tax. In line with our survey findings, we show that women adjust their labor supply following a change in withholding taxes. Importantly, the German institutional setting allows couples to partially redistribute the withholding tax burden from one partner to the other, and the majority shifts parts of the withholding tax burden from the husband to the wife. Our results suggest that the increased withholding tax burden of married women in Germany contributes to their low labor supply. The finding also highlights that governments should be aware that overwithholding results in an overestimation of the actual income tax and thus distorts labor supply incentives.
