In an economy with a non-convex production sector, we provide an assumption on each individual producer, which implies that the survival assumption holds true at the aggregate level for general pricing rules. For the marginal pricing rule, we derive this assumption from the bounded marginal...

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.
