Mircrosimulation models (MSM) and Computable General Equilibrium models (CGE) have both been widely used in policy analysis. The combination of these two model types allows the utilisation of the advantages of both types. The aim of this paper is to describe the state-of-the-art in simulation...

In this paper, we define a new class of richness measures. In contrast to the often used headcount, these new measures are sensitive to changes in rich persons' income and therefore allow for a more sophisticated analysis of richness. We demonstrate the application of these new measures to...

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...

This paper deals with the impact of electoral competition on politicians' outside earnings. In our framework, politicians face a tradeoff between allocating their time to political effort or to an alternative use generating outside earnings. The main hypothesis is that the amount of time spent...

Clemens Fuest, Andreas Peichl und Thilo Schaefer, Finanzwissenschaftliches Institut an der Universität zu Köln, analysieren die Beschäftigungs- und Finanzierungswirkungen des Grundeinkommens-Konzepts von Dieter Althaus. Ihrer Meinung nach entlastet das vorgeschlagene Modell nicht den...

Clemens Fuest, Andreas Peichl und Thilo Schaefer, Universität zu Köln, sowie Joachim Mitschke stellen in diesem Beitrag das von ihnen entwickelte Kombilohnmodell, den "Kölner-Kombilohn", vor und berechnen Beschäftigungs- sowie Aufkommenswirkungen ihres Vorschlags, bei dem gering entlohnte,...

In Germany, two observations can be made over the past 20 years: First, income inequality has been constantly increasing while, second, the average household size has been declining dramatically. The analysis of income distribution relies on equivalence-weighted incomes which take into account...

The success of the flat rate tax in Eastern Europe suggests that this concept could also be a model for the welfare states of Western Europe. The present paper uses a simulation model to analyse the effects of revenue neutral flat rate tax reforms on equity and efficiency for the case of...

Closely following recent innovations in the literature on the multidimensional measurement of poverty, this paper provides similar measures for the top of the distribution using a dual cutoff method to identify individuals, who can be considered as rich in a multidimensional setting. We use this...
