How far can we go in weakening the assumptions of the general equilibrium model? Existence of equilibrium, structural stability and finiteness of equilibria of regular economies, genericity of regular economies and an index formula for the equilibria of regular economies have been known not to...

The Heckscher-Ohlin model with arbitrary number of goods, factors and countries (consumers) and no restrictions on factor trading is shown to be equivalent to an exchange model whose goods are the productive factors while consumer's indirect demands for factors are derived from their actual...

Social demand functions result from the budget constrained maximization of "social preferences" or "other regarding preferences." These preferences are non-selfish in the sense that they also depend on other consumers' wealth. This paper addresses the robustness to wealth externalities of the...

A dynamic pure-exchange general equilibrium model with uncertainty is studied. Fundamentals are supposed to depend continuously on states of nature. It is shown that: 1. if financial markets are complete, then asset prices vary continuously with states of nature, and; 2. if financial markets are...

We study internalization of production externalities in perfectly competitive markets where production plans are decided by majority voting. Since shareholders want firms to maximize dividends of portfolios rather than profits, they are interested in some internalization. Two governances, namely...

An economy with two dates is considered, on state at the first date and a finite number of states at the last date. Shareholders determine production plans b voting -one share, one vote- and at r-majority stable equilibria, alternative production plans are supported by at most rx100 percent of...

In absence of markets for externalities, the authors look for governances and conditions under which majority voting among shareholders is likely to give rise to efficient internalization. The central and natural role played by a governance of stakeholders is underlined and benchmarked.

An economy with two dates is considered, one state at the first date and a finite number of states at the last date. Shareholders determine production plans by voting — one share, one vote — and at ?-majority stable stock market equilibria, alternative production plans are supported by at...

We study internalization of production externalities in perfectly competitive markets where production plans are decided by majority voting.

A pure exchange, general equilibrium model is considered and the equilibrium set is studied. It is shown for all total endowments and an open and dense set of preferences that if there arel2 commodities andm2 consumers then there exists a set of distributions of endowments with nonempty interior...
