The aim of this paper is to apply recently proposed individual welfare measures in the context of random utility models of labour supply. Contrary to the standard practice of using reference preferences and wages, these measures preserve preference heterogeneity in the normative step of the...

How can public pension systems be reformed to ensure fiscal stability in the face of increasing life expectancy? To address this pressing open question in public finance, we estimate a life-cycle model in which the optimal employment, retirement and consumption decisions of forward-looking...

Die Vereinbarkeit von Beruf und Familie ist seit einiger Zeit eines der wichtigsten familienpolitischen Ziele. Zum einen, weil es Eltern, insbesondere Müttern, erleichtert werden soll, erwerbstätig zu sein. Zum anderen, weil die Hoffnung besteht, dass die Geburtenrate steigt, wenn berufliche...

Das Institut für Arbeitsmarkt- und Berufsforschung (IAB) und das Deutsche Institut für Wirtschaftsforschung (DIW) simulieren die fiskalpolitischen und gesamtwirtschaftlichen Effekte von Investitionen in die Integration der Flüchtlinge, die im Jahr 2015 zugewandert sind. Die Simulationen sind...

This paper contributes to the debate about the optimal design of tax-transfer systems. Based on the theory of optimal taxation, combined with microsimulation and microeconometric techniques we derive the welfare function which makes the current German tax and transfer system for single women...

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

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 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...
