This paper is about instability of equilibrium real rents in a pure exchange economy. Our main result hinges upon a low degree of substitutability between housing services and other commodities together with a low share of owner-occupied houses. We argue that regions or economies with a low...

This paper presents a simple model of housing cycles in a two good economy. We establish that nonsubstitutability between housing services and other commodities along with high degree of heterogeneity in home ownership may lead to a stable spiral path converging to a steady-state equilibrium of...

We introduce the E-correspondence principle for stochastic dynamic expectations models as a tool for comparative dynamics analysis. The principle is applicable to equilibria that are stable under least squares and closely related learning rules. With this technique it is possible to study,...

An economy exhibits structural heterogeneity when the forecasts of different agents have different effects on the determination of aggregate variables. Various forms of structural heterogeneity can arise and we study the important case of economies in which agents' behavior depends on forecasts...

Solute crystallization equilibrium contains a stable equilibrium and an unstable equilibrium. The system must get across an energy peak of unstable equilibrium first, and then get into an energy valley of stable equilibrium during the solute crystallization. When solution is diluted, the energy...

The stability of market economy is defined and stability conditions deduced which do not appear to restrict preferences in any significant manner. This assumes importance when considering economies where diversity among agents is known to exist. It is shown that if a condition on the rank of the...

In this paper we extend the analysis of optimal monetary policy rules in terms of stability of an economy, started by Evans and Honkapohja (2003b), to the case of heterogeneous private agents learning. Following Giannitsarou (2003), we pose the question about the applicability of the...

For the evaporation of the pure liquid under the condition of constant temperature and constant external pressure, the phase equilibrium of the liquid vapor in the bubble and the liquid outside the bubble is always a kind of stable equilibrium whether there is air or not in the bubble. If there...

An economy exhibits structural heterogeneity when the forecasts of different agents have different effects on the determination of aggregate variables. We study the important case of economies in which agents' behavior depends on forecasts of aggregate variables and show how different forms of...

We consider a supply function model of a poolco electricity market where demand varies significantly over a time horizon such as a day and also has a small responsiveness to price. Although there are equilibria yielding prices at peak that are close to Cournot prices, it is known that the wider...
