Das deutsche Einkommenssteuerrecht ist zu komplex und zu intransparent. Zahlreiche Reformkonzepte wurden in den vergangenen Jahren öffentlich diskutiert. Allerdings ist es bisher nicht gelungen, den bestehenden Zielkonflikt zu überwinden und positive Beschäftigungs- und Verteilungswirkungen...

Die Steuervorschläge der Parteien stellen einen wesentlichen Teil ihrer Wahlprogramme für die Bundestagswahl 2013 dar. Sie werden in der Öffentlichkeit kontrovers diskutiert, da davon ausgegangen wird, dass sie einen erheblichen Einfluss auf die Wahlentscheidung haben wer-den. Daher stellt...

Inequality has increased considerably in many Western countries over the past decades. When dealing with economic inequality as a research subject the question "inequality of what among whom" arises. Analyses of inequality are typically concerned with the distribution of wages, earnings or...

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:...

Previous reviews of static labor supply estimations concentrate mainly on the evidence from the 1980s and 1990s, Anglo-Saxon countries and early generations of labor supply modeling. This paper provides a fresh characterization of steady-state labor supply elasticities for Western Europe and the...

There is still considerable dispute about the magnitude of labor supply elasticities. While differences in micro and macro estimates are recently attributed to frictions and adjustment costs, we show that relatively low labor supply elasticities derived from microeconometric models can also be...

The current debt crisis has given rise to a debate about deeper fiscal integration in Europe. The view is widespread that moving towards a 'fiscal union' would have a stabilising effect in the event of macroeconomic shocks. In this paper we study the economic effects of introducing two elements...

We suggest the first large-scale international comparison of labor supply elasticities for 17 European countries and the US, separately by gender and marital status. Measurement differences are netted out by using a harmonized empirical approach and comparable data sources. We find that own-wage...

Mircrosimulation models (MSM) and Computable General Equilibrium models (CGE) have both been widely used in policy analysis. The combination of these two model types allows the utilisation of the advantages of both types. The aim of this paper is to describe the state-of-the-art in simulation...
