Das Papier gibt einen einführenden Überblick über wesentliche Konzepte der Messung von Einkommens- bzw. Vermögensungleichheit und Armut. Es werden grundlegende Prinzipien der Ungleichheitsmessung vorgestellt und analysiert, inwieweit einige gebräuchliche Ungleichheitsmaße diesen Prinzipien...

In a recent paper Ganguli and Yang [2009] demonstrate, that there can exist multiple equilibria in a financial market model á la Grossman and Stiglitz [1980] if traders possess private information regarding the supply of the risky asset. The additional equilibria differ in some important...

This paper deals with credit market imperfections and idiosyncratic risks in a twosector heterogeneous agent dynamic general equilibrium model of occupational choice. We focus especially on the effects of tightening financial constraints on macroeconomic performance, entrepreneurial risktaking,...

This paper discusses the emergence of endogenous redistributive cycles in a stochastic growth model with incomplete asset markets and heterogeneous agents, where agents vote on the degree of progressivity in the tax.transfer.scheme. The model draws from Bénabou (1996) and ties the bias in the...

This paper investigates the redistributive effects of taxation on occupational choice and growth. We discuss a two.sector economy in the spirit of Romer (1990). Agents engage in one of two alternative occupations: either self.employment in an intermediate goods sector characterized by...

This paper analyzes conditions for existence of a strongly rational expectations equilibrium (SREE) in models with private information, where the amount of private information is endogenously determined. It is shown that the conditions for existence of a SREE known from models with exogenously...

This paper examines the effects of credit market imperfections and idiosyncratic risks on occupational choice, capital accumulation, as well as on the income and wealth distribution in a two sector heterogeneous agent general equilibrium model. Workers and firm owners are subject to...

The paper demonstrates how the Estability principle introduced by Evans and Honkapohja can be applied to models with heterogeneous and private information in order to assess the stability of rational expectations equilibria under learning. The paper extends already known stability results for...
