In the year 2000, the German government passed the most ambitious tax reform in postwar German history aiming at a significant tax relief for households. An important aim of this tax reform was to improve work incentives and, thereby, foster employment. Drawing on data of the German Socio...

This paper studies the speed at which workers' pre-tax earnings respond to tax changes along the intensive margin. We do so in the context of Germany, where a large discontinuity - or notch - in the tax schedule induces sharp bunching in the earnings distribution. We analyze earnings responses...

This paper assesses Italy’s 2019 tax and benefit reforms, analyses hypothetical reforms and proposes a reform package that balances goals of reducing poverty, encouraging employment and fiscal sustainability. Using the OECD’s Tax-Benefit and the EUROMOD microsimulation models, it shows that...

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

We estimate a model of labour supply and participation in multiple cash and in-kind welfare programmes. The modeling exploits a reform that affected U.K. single mothers. In-work cash entitlements increased under this reform but eligibility to in-kind child nutrition programmes was lost for some...

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:...

This paper describes the ifo Tax and Transfer Behavioral Microsimulation Model (ifoMSM-TTL), a policy microsimulation model for Germany. The model uses household microdata from the German Socio-Economic Panel and firm data from the German Linked Employer-Employee Dataset. This microsimulation...

In January 2015, Germany introduced a federal, statutory minimum wage of 8.50 € per hour. This study evaluates the effects of this policy on regular and marginal employment and on welfare dependency. Based on county-level administrative data, this study uses the difference-in-differences...

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...
