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...
