The Tax-Transfer-Simulation-Model (STSM) is a microsimulation model used for the empirical analysis of the effects of taxes, statutory social security contributions and social transfers on the distribution of incomes, labour supply decisions of private households, and their budgetary (fiscal)...

In this paper we develop a structural model of female employment and fertility which accounts for intertemporal feedback effects between the two outcomes. We identify the effect of financial incentives on the employment and fertility decision by exploiting variation in the tax and transfer...

This paper contributes to the debate about the optimal design of tax-transfer systems. Based on the theory of optimal taxation, combined with microsimulation and microeconometric techniques we derive the welfare function which makes the current German tax and transfer system for single women...

We analyze the work incentives and labor supply effects of the so-called mini-jobs reform (subsidies of social security contributions to people with low-earnings jobs) introduced in Germany in April 2003. The analysis is based on a structural labor supply model embedded in a detailed tax-benefit...

We estimate the elasticity of enrollment into higher education with respect to the amount of means tested student aid (BAfoeG) provided by the federal government using the German Socioeconomic Panel (SOEP). Potential student aid is derived on the basis of a detailed taxbenefit microsimulation...

We analyze potential labor supply effects of a shift from the current German system of taxation of married couples to a system of limited real income splitting on the basis of econometric household labor supply model embedded in a tax-benefit model. Our simulation results show relatively small...

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...
