Diese Dokumentation beschreibt das integrierte Steuer-Transfer-Mikrosimulations- und CGE-Modell FiFoSiM des Finanzwissenschaftlichen Forschungsinstituts an der Universität zu Köln (FiFo). FiFoSiM unterscheidet sich von den bisherigen Steuer- und Transfersimulationsmodellen auf zweierlei Weise...

Angesichts der dramatischen demographischen Entwicklung in Deutschland hat das Interesse der Politik an der wirtschaftlichen und sozialen Situation von Haushalten mit Kindern in den letzten Jahren stark zugenommen. Das gilt nicht zuletzt auch für den Bereich der Steuerpolitik. Im vorliegenden...

The potential economic outcomes resulting from a flat rate of income tax have been the subject of an ongoing academic and political debate. Many observers have suggested that the introduction of a flat tax would be beneficial for a country's economy, having a positive influence on the labor...

Although discrete hours choice models have become the workhorse in labor supply analyses. Yet, they are often criticized for being a black box due to their numerous underlying modeling assumptions, with respect to, e.g., the functional form, unobserved error components or several exogeneity...

There is a huge variation in the size of labor supply elasticities in the literature, which hampers policy analysis. While recent studies show that preference heterogeneity across countries explains little of this variation, we focus on two other important features: observation period and...

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:...

There is still considerable dispute about the magnitude of labor supply elasticities. While differences in estimates especially between micro and macro models are recently attributed to frictions and adjustment costs, we show that the variation in elasticities derived from structural labor...
