In diesem Jahr wurde der in Princeton lehrende, britisch-amerikanische Ökonom Angus Deaton mit dem Nobelpreis für Wirtschaftswissenschaften ausgezeichnet. Es werden damit - wie es in der offi ziellen Verlautbarung des Nobelpreiskomitees heißt - seine Analysen von Konsum, Armut und Wohlfahrt...

This paper examines the consequences of international financial integration in a two sector heterogeneous agent dynamic general equilibrium model of occupational choice with financial constraints and idiosyncratic risks. We discuss the macroeconomic and distributional effects of financial market...

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

Das Institut für Volkswirtschaftslehre der Universität Lüneburg legt hiermit seinen dritten eigenständigen Forschungsbericht vor. Seit 1999 erschien unser Bericht als Teil des Forschungsberichts des Fachbereichs Wirtschafts- und Sozialwissenschaften; dieser Bericht wurde nach dem...

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 combines the standard incomplete markets model of uninsurable idiosyncratic risks and borrowing constraints with the Arrow/Romer approach to endogenous growth to analyze the interaction of risk, growth, and inequality, the latter also endogenously determined in equilibrium. We derive...

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...

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

The paper demonstrates how the E-stability principle introduced by Evans and Honkapohja [2001. Learning and Expectations in Macroeconomics. Princeton University Press, Princeton, NJ] can be applied to models with heterogeneous and private information in order to assess the stability of rational...
