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....

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.

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.
