We estimate the effects of the reform of the German Unemployment Insurance that replaced the wage related Unemployment Assistance with an income maintenance program and stronger means testing. We model the tax-benefit system and use the Socio-Economic Panel. We estimate a discrete labour supply...

In this paper we estimate the effects of an unconditional basic income on labor supply and income distribution with a special focus on the incentives to work in the family context. An unconditional basic income guarantees every citizen a minimum income without any means-testing. We simulate a...

Social assistance and unemployment assistance, which provide means tested income support (social welfare) without pre-specified time limits, are viewed as one important reason for the persistently high level of unemployment in Germany by many economists. In order to increase work incentives and,...

Benefit sanctions imposed on non-compliant welfare recipients are a new element in the German welfare system. In practice, the sanction policy and the application of sanctions vary considerably across the 439 welfare agencies. Based on combined administrative and survey data, these differences...

This paper assesses the effects that an introduction of the French family splitting mechanism would have on German families' labour supply and intra-household consumption behaviour. We use simulated real world microdata created by means of a 'deterministic' collective labour supply model. The...

This paper compares predictions obtained for the analysis of tax reforms with collective and unitary models of household labour supply and consumption behaviour. We simulate real world microdata by means of a collective approach, using a compound procedure of estimation and calibration based on...

We present a model that integrates the discrete working time choice of heterogenous households into a general equilibrium setting where wages are determined by sectoral bargaining between firms and trade unions. The model is calibrated to German micro and macro data. We then use it to analyse...

We compare two options of integrating discrete working time choice of heterogenous households into a general equilibrium model. The first, known from the literature, produces household heterogeneity through a working time preference parameter. We contrast this with a model that directly...

We report empirical evidence from the first field experiments to be conducted in Germany with program and control groups between 1999 and 2002. The evaluated program called ?Targeted Negative Income Tax (TNIT)? is a time-restricted employee subsidy for means-tested welfare recipients. We focus...

The labor supply of West German married and cohabiting couples is analyzed using a discrete choice model. Following van Soest (1995), the labor supply decision is based on a household utility function which is determined by the leisure of the two spouses and net household income. Furthermore,...
