This article investigates the impact of tax simplification on various indicators of the efficiency of the tax system and on the distribution of income. The analysis is based on a simulation model (FiFoSiM) using German income tax and household survey microdata. We model tax simplification as the...

This paper deals with the impact of electoral competition on politicians ́outside earnings. We propose a simple theoretical model with politicians facing a tradeoff between allocating their time to political effort or to an alternative use generating outside earnings. The model has a testable...

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...

When comparing tax benefit systems across Europe, Germany is usually regarded as a country with a high level of taxes and contributions which is often seen as a main challenge for the economic performance of the welfare state. In this paper, we analyse the progressivity and redistribution...

Using panel data on the full population of corporate tax returns of Armenian firms, we study the behavioral response of firms to three size-dependent regulations. We find: i) a strong response to an accounting notch where International Financial Reporting Standards become mandatory; ii) a...

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...

The consistent underestimation of inequality of opportunity has led some scholars to call into question the usefulness of such estimates. In this paper we argue that neglecting heterogeneity in the influence of circumstances across types as well as neglecting heterogeneity in type-specific...

This contribution develops a blueprint for a European fiscal union. We argue that a viable European fiscal union can be constructed without joint liability for public debt or a centralized government with a large common budget. Such a fiscal union should combine elements of market discipline...
