This paper demonstrates that the adaptive learning approach to modelling private sector expectations can be used as an equilibriumselection mechanism in a natural-rate monetary model with unemployment persistence. In particular, it is shown that only one of the two rational expectations...

We study adaptive learning in a monetary overlapping generations model with sticky prices and monopolistic competition for the case where learning agents observe current endogenous variables. Observability of current variables is essential for informational consistency of the learning setup with...

This exercice provides all eigenvalues and eigenvectors of the autoregressive matrix found in classical recursive least square theory.

Agent heterogeneity has been used in recent economic literature to justify nonlinear dynamics for the time paths of aggregate economic variables. In this paper, the mechanism through which heterogeneous agents leads to chaotic motion is explained. Adding to a system with initial behavior...

The precedent for solving expectational difference equations has been to solve converging equations backwards and diverging equations forward by assuming the solution is bounded. This precedent often leads to incorrect solutions and has less than rigorous foundations. More rigorous procedures...

This paper studies a closed economy with a continuum of agents and moral hazard. Economic agents in the economy operate a stochastic production technology with capital and labor inputs in which the latter is private information. I characterize efficient allocations of capital, labor, and...

Die Heckscher-Ohlin-Modellierung mit den Faktoren nieder- und höherqualifizierte Arbeitskraft und Arbeitslosigkeit beziehungsweise einem Minimallohn wird einer genaueren Analyse unterzogen und erfährt dabei deutliche Kritik. Anschließend wird ein Ansatz zur Remodellierung der von ihr...

The elasticity of intertemporal substitution (EIS) at the macro level has been estimated mostly based on endowment economy models and these estimates are very sensitive to the choice of interest rates that are used for estimation. Estimates based on production economy models do not need...

It is assumed that performance of production system can be described with the three variables: amount of production equipment -- capital stock $K$ and 'consumption' of labour L and capital services S. It is shown that the production function can be specified as the known Cobb- Douglas production...

The paper explores the impacts of heterogeneity in degree of relative risk aversion on the balance on current account in a two-country endogenous growth model. It concludes that, like the heterogeneity of demographic changes, the heterogeneity in degree of relative risk aversion generates...
