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...

Estimates of labour supply effects of recent UK reforms in the area of direct taxes and benefits show that policy can have significant influence on the level of employment. We confirm this in a simulation of in-work support system introduced into the German tax and benefit system. Our simulation...

Labor supply in the market for low-paid jobs in Germany is strongly influenced by tax exemptions - even for individuals to whom these exemptions do not apply. We present compelling evidence that an individual's choice set depends on other workers' preferences because firms cater their job offers...

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...

Financial support for families with children implies inherent trade-offs some of which are less obvious than others. In the end these trade-offs determine the effectiveness of policy with respect to the material situation of families and employment of their parents. We analyse several kinds of...

We analyze the effects of three alternative proposals to reform the taxation of families relative to the current German system of joint taxation of couples and child allowances: a French-type family splitting and two full family splitting proposals. The empirical analysis of the effects of these...

In this paper we empirically derive the welfare effects of a shift from joint taxation with full income splitting to a revenue neutral system of individual taxation in Germany. For the empirical welfare evaluation we estimate the preference heterogeneity in the population and use normative...

In this paper, we address the question whether family support via the income tax system is more generous in France than in Germany, as it is often claimed in the public debate. We use two micro-data sets and a micro-simulation model to compare effective average tax rates for different household...
