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...

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 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...

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 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...

Summary Following standard real business cycle theory, long run economic growth and short run business cycle fluctuations are attributed to a series of productivity shocks propagated by the economic system which is assumed to be in a rational expectations equilibrium. Characterizing the...

This paper examines the dynamics of wealth and income inequality along the business cycle and assesses how they are related to fluctuations in the functional income distribution. In a panel estimation for OECD countries between 1970 and 2016 we find that on average income inequality - measured...

A two-sector incomplete markets model with heterogeneous agents can be used to study the distributional effects of the COVID-19 lockdown. While negative aggregate welfare effects of the lockdown are unavoidable, the size of aggregate welfare effects as well as the distribution of the welfare...
