This paper examines the effects of increasing marginal tax rates on labour supply in a setting in which workers may hold two jobs and may be constrained in their weekly hours on their main jobs. A panel data, multi-equation labour supply model is estimated with correction for tax system...

This paper presents an evaluation of the tax-transfer treatment of married couples in 15 EU countries using the EUROMOD microsimulation model. First, we show that many tax-transfer schemes in Europe feature negative jointness defined as a situation where the tax rate on one person depends...

Der Abstand zwischen dem potentiellen Nettoarbeitseinkommen und dem Sozialhilfeanspruch (Lohnabstand) wird für verschiedene Haushaltstypen gemessen. Er ist im Jahr 2001 für Haushalte, die aus drei oder mehr Personen bestehen, gering. Der Lohnabstand hat in den vergangenen 40 Jahren abgenommen....

Based on a description of the German system of taxes and transfers, the incentives to work are analyzed for several groups of the labor force. The effects of the Hartz IVʺ reform (effective from 2005 onwards) on the incentives receive particular attention. It turns out that the marginal...

We use a behavioural microsimulation model embedded in a numerical optimization procedure in order to identify optimal (social welfare maximizing) tax-transfer rules. We consider the class of tax-transfer rules consisting of a universal basic income and a tax defined by a 4th degree polynomial....

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...

The income tax rate structure introduced in 2007 was changed in 2009. The income tax rates will be lowered in 2010, too. The effects on the wage income tax revenues and on the incentives to work are analyzed. It turns out that bracket creepʺ will remain a problem in Germany. -- Wage income tax...

Shifting taxes from labor income to consumption is regularly suggested as a measure to induce work incentives. We investigate the effect of increases in the Value Added Tax on labor supply and the income distribution in Germany, which is compensated by a revenue-neutral reduction in...

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