This article describes ZEW-EviSTA®, the microsimulation model developed and used at ZEW - Centre for European Economic Research in Mannheim. The model simulates the German tax and transfer system using household micro level data. By estimating fiscal effects, labor market outcomes as well as...

I propose a method to decompose changes in income inequality into the contributions of policy changes, wage rate changes, and population changes while considering labor supply reactions. Using data from the Socio-Economic Panel (SOEP), I apply this method to decompose the increase in income...

We analyze the long-run growth effects of automation in the canonical overlapping generations framework. While automation implies constant returns to capital within this model class (even in the absence of technological progress), we show that it does not have the potential to lead to positive...

Using new survey and experimental data for a representative sample of the German population, we study preferences for tax simplification. The general wisdom seems to suggest that most tax systems are overly complex and that tax simplification is generally desirable. Consistent with this general...

We study reforms of non-linear income tax systems from a political economy perspective. We present a median voter theorem for monotonic tax reforms, reforms so that the change in the tax burden is a monotonic function of income. We also provide an empirical analysis of tax reforms, with a focus...

Heterogeneous-agent New Keynesian models with sticky nominal wages usually assume that wage-setting unions demand the same amount of hours from all households. As a result, unions do not take account of the fact that (i) households are heterogeneous in their willingness to work, and that (ii)...
