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...

We solve the problem of a social planner who seeks to minimize inequality via transfers with a fixed public budget in a distribution of exogenously given incomes. The appropriate solution method depends on the objective function: If it is convex, as in the case of the absolute mean deviation, it...

Constructing measures of post-tax income inequality that are consistent with national accounts requires the allocation of the entirety of government expenditure to individuals. About half of government expenditure in the United States takes the form of in-kind collective expenditure (e.g.,...

Individuals vary considerably in how much they earn during their lifetimes. This study examines the role of the tax-and-transfer system in mitigating such inequalities, which could otherwise lead to disparities in living standards. Utilizing a life-cycle model, we determine that taxes and...

This paper examines the evolution of the redistributive role of the State in Brazil at the beginning of the 21st century. For this purpose, we compute the marginal effects of the cash transfers, taxes, and in-kind benefits on inequality using the Lerman-Yitzhaki progressivity index. Our main...

We study three budget-neutral reforms of the German tax and transfer system designed to improve work incentives for people with low incomes: a feasible flat tax reform that provides a basic income which is equal to the current level of the means tested unemployment benefit, and two alternative...

Using a laboratory experiment, we present first evidence that social image concerns causally reduce the take-up of an individually beneficial transfer. Our design manipulates the informativeness of the take-up decision by varying whether transfer eligibility is based on ability or luck, and how...
