Die Preise für Energierohstoffe wie Gas und Rohöl sind in den vergangenen Monaten auf Rekordniveau gestiegen. Sollte Klimapolitik auf diese Energiepreisanstiege reagieren und kurzfristig CO2 -Preise anpassen, um Haushalte zu entlasten? In unserer Analyse adressieren wir diese Frage in einem...

Das Papier untersucht, wie Erwartungsbildung mit Hilfe neuronaler Netze modelliert werden kann. Die Grundlage bildet ein Cobweb-Modell, in dem Firmen Preiserwartungen auf Basis eines Feedforward-Netzes bilden.<br />Zunächst wird anhand von Simulationen gezeigt, daß Firmen durch neuronale...

This paper analyzes the relationship between the expectational stability of rational expectations equilibria and the possible convergence of adaptive learning processes. Results obtained using recursive least squares lead to the conjecture that a correspondence between these both selection...

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 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...

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,...

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...

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...
