The German Federal Government has expanded subsidies for employees with low gross wages (midijob employees) as of January 1, 2023, and raised the upper earnings limit to 2,000 euros. As a result, around 6.2 million midijob employees will benefit from paying reduced social security contributions...

Two traditional options for reforming Ehegattensplitting, the joint taxation of married couples with full income splitting, are de facto income splitting (Realsplitting) or individual taxation with a transferable personal allowance. However, these proposals do not significantly reduce the...

In the year 2000, the German government passed the most ambitious tax reform in post-war German history aiming at a significant tax relief for households.

In this paper we develop a dynamic structural life-cycle model of labor supply behavior which fully accounts for the effects of income tax and transfers on labor supply incentives. Additionally, the model recognizes the demand side driven rationing risk that might prevent individuals from...

In this paper we develop a discrete model of optimal taxation of married couples and empirically discuss the optimality of income taxation for this group. To this end, we derive the social welfare function which guarantees that joint taxation of married couples is optimal. We will contrast this...

This paper extends previous research about the determinants of reservation wages by analysing the effect of progressive income taxation on the ratio between reservation and net market wages. Based on micro data for Germany (SOEP) we show that joint income taxation in Germany which discriminates...

We estimate a dynamic structural life-cycle model of employment, non-employment and retirement that includes endogenous accumulation of human capital and intertemporal non-separabilities in preferences. Additionally, the model accounts for the effect of the tax and transfer system on work...
