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...

Usually, an economic good isn't available gratuitously, but the case of information goods and services (IGS) is specific. Their intrinsic properties allow zero prices that is unconceivable for the others economic private goods. The gratuitousness is not the aim of productive activity ; it...

In this paper, we introduce input-specific externalities in a dynamic general equilibrium model with heterogeneous households and a finance constraint (Woodford (1986)). In contrast to existing papers, average labor and capital have not a positive impact on the total productivity of factors, but...
