Deutschland wird häufig ein im europäischen Vergleich überdurchschnittliches Abgabenniveau bescheinigt. Da dies als eine der Hauptursachen für vergleichsweise schwaches Wachstum und hohe Arbeitslosigkeit gilt, werden in der wirtschaftspolitischen Debatte vermehrt Reformen des progressiven...

The flat income tax has become increasingly popular recently, yet its implementation is limited to Eastern Europe. We analyse the distributional and efficiency effects of flat tax scenarios for Western European countries. Our simulations show that flat tax rates required to attain revenue...

In Germany, there is an ongoing debate about how to increase the efficiency of the social security system and especially its financing. The aim of this paper is to simulate different financing systems for Germany. The introduction of a Liberal British or the Southern Greek financing system...

European countries have the world’s most redistributive tax and transfer systems. While they have been well equipped to deal with vertical inequality - that is, fostering redistribution from the rich to the poor - less is known about their performance in dealing with horizontal inequality,...

Following the report of the Stiglitz Commission, measuring and comparing well-being across countries has gained renewed interest. Yet, analyses that go beyond income and incorporate non-market dimensions of welfare most often rely on the assumption of identical preferences to avoid the...

We analyze different options for the design of a common unemployment insurance system for the euro area (EA). We assess their effectiveness to act as an insurance device in the presence of asymmetric macroeconomic shocks. Running counterfactual simulations based on micro data for the period...

This paper analyzes the effectiveness of the tax and transfer systems in the European Union and the US to act as an automatic stabilizer in the current economic crisis. We find that automatic stabilizers absorb 38 per cent of a proportional income shock in the EU, compared to 32 per cent in the...

Despite numerous studies on labor supply, the size of elasticities is rarely comparable across countries. In this paper, we suggest the first large-scale international comparison of elasticities, while netting out possible differences due to methods, data selection and the period of...

Whether observed differences in redistributive policies across countries are the result of differences in social preferences or efficiency constraints is an important question that paves the debate about the optimality of welfare regimes. To shed new light on this question, we estimate labor...

We analyze how the combined effect of automatic stabilizers and discretionary changes in tax-benefit systems have affected the cushioning of income shocks in the Euro zone and the EU-27 in the period 2007-2014. We propose a new summary measure of the combined effect of automatic stabilizers and...
