Based on micro data for Germany (SOEP) we show that joint income taxation in Germany which discriminates by marital status, has a strong and highly significant impact on the reservation/market wage ratio. Relative to single filers, this leads to strong negative labour supply incentives for secondary earners and to positive incentives for first earners in married couples.
