Analyzing a homogenous household setting with endogenous fertility and endogenous labor supply, we demonstrate that moving from joint taxation to individual taxation and adapting child benefits so as to keep fertility constant entails a Pareto improvement. The change is associated with an...

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:...

We present a non-cooperative model of a family's time allocation between work and a home-produced public good, and examine whether the income tax should apply to couples or individuals. While tax-induced labor supply distortions lead to overprovision of the public good, spouses' failure to...

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...

This documentation describes FiFoSiM, the integrated tax benefit microsimulation and CGE model of the Center of Public Economics at the University of Cologne. FiFoSiM consists of three main parts. The first part is a static tax benefit microsimulation module. The second part adds a behavioural...

This paper explores the implications of gender-based income taxation in a non- cooperative model of a couple's time allocation between market work and providing a household public good. We find that the optimal structure of differential taxation by gender is solely determined by spouses'...
