This paper proves the existence of a general equilibrium in a financial model with transaction costs. The general equilibrium is shown to exist in a model with convex trading technology, in which the agents include consumers, production firms, brokers and dealers. When the trading technology is...

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...

This paper focuses on the influence of the influence of the opening of a market of allowances, such as the European Union Emission Trading Scheme, on the general equilibrium of an economy. Assuming there existed an equilibrium before the opening of this new market, we describe the changes in the...

In this paper we prove an index formula for production economies with externalities. We allow for non-convexities in the production sector and set the firms behavior according to general pricing rules. We derive as corollaries existence of a general equilibrium in such a setting.

The purpose of the paper is to introduce a tighter definition for the marginal pricing rule. By means of an example, we illustrate the improvements that one gets with the new definition with respect to the former one with the Clarke's normal come.

The study is aimed to investigate the convergence to equilibrium of trajectories generated by contractual processes. “Contractual process” is a view on economy’s self-regulation, describing any state of exchange economy as a set of barter contracts among agents/coalitions. It is assumed...

We study identification in a class of three-equation monetary models. We argue that these models are typically not identified. For any given exactly identified model, we provide an algorithm that generates a class of equivalent models that have the same reduced form. We use our algorithm to...

The general purpose of this paper is to prove quasiequilibrium existence theorems for production economies with general consumption sets in an infinite dimensional commodity space, without assuming any monotonicity of preferences or free-disposal in production.

In this paper the existence of unemployment is partly explaines as being the result of coordination failures. This is achieved by considering a standard general equilibrium modes and splitting the set of commodities in two groups. The first group contains commodities like gold. The prices of...
