This paper describes IZAΨMOD, the policy microsimulation model of the Institute for the Study of Labor (IZA). The model uses household microdata from the German Socio-Economic Panel Study and firm data from the German linked employer-employee dataset LIAB. IZAΨMOD consists of three components:...

Der Beitrag untersucht die Arbeitsmarktwirkungen einer vom Deutschen Gewerkschaftsbund vorgeschlagenen Subventionierung der Sozialbeiträge über einen allgemeinen Freibetrag. Im Rahmen eines mit SOEP-Daten geschätzten diskreten Arbeitsangebotsmodells werden die Wohlfahrtseffekte des Konzepts...

This research evaluates the impact on German household labor supply of various subsidy schemes proposed to foster low-wage employment. Using data from the German Socio-Economic Panel, we estimate a discrete choice model of household labor supply. On the basis of the estimated labor supply...

We assess the labour supply effects of two 'making work pay' reforms in Germany. We provide evidence in favour of policies that distinguish between low effort and low productivity by targeting individuals with low wages rather than individuals with low earnings. In assessing the policies we...

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...

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...

This paper formulates a simple model of female labor force decisions which embeds an in-work benefit reform and explicitly allows for announcement and implementation effects. We explore several mechanisms through which women can respond to the announcement of a reform that increases in-work...

In this paper we examine the link between wage inequality and consumption inequality using a life cycle model that incorporates household consumption and family labor supply decisions. We derive analytical expressions based on approximations for the dynamics of consumption, hours, and earnings...
