This paper focuses on the influence on the general equilibrium of an economy of the opening of markets of allowances, such as the European Union Emission Trading Scheme. Assuming there existed an equilibrium before the opening of allowances' markets, we describe the changes in the firms behavior...

This paper studies the welfare improvement properties of a market of allowances in an economy with a single type of externality. We show that thanks to the opening of such a market the Pareto optima can be decentralized as marginal pricing equilibria. However, the set of equilibria is much...

We prove that the degree of the equilibrium correspondence of an economy with increasing returns and external effects is equal to (−1)L−1 where L is the dimension of the space of goods. This allows us to infer existence, finiteness and uniqueness results.

On démontre la stabilité de l'équilibre dans une économie walrasienne complètement décentralisée dans laquelle les prix sont fixés par les agents économiques et où échange et production ont lieu hors équilibre.

Within a standard framework à la Arrow-Debreu, we investigate the dynamics emerging from the interactions of heterogeneous households and firms that are adaptive price setters and financially constrained. We show that depending on the stringency of the financial constraints the model can settle...

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.

This paper focuses on 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 firms behavior...

In this paper, we extend the problem of decentralization of Pareto optima in an economy with production externalities to the case where the production capacities upon which Pareto optimality is defined may differ from the aggregate of the firms expectations about their production possibilities....

Each Party of the Kyoto Protocol on Climate Change must achieve quantified green-house gases emission reduction. one of the major policy instrument to be used to comply with these commitments is the opening of an emission allowances market. This paper analyzes, in the general equilibrium...

We present a mathematical model for the analysis of the bargaining games based on private prices used by Gintis to simulate the dynamics of prices in exchange economies, see [Gintis 2007]. We then characterize, in the Scarf economy, a class of dynamics for which the Walrasian equilibrium is the...
