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...

A commodity is shared between some individuals; some selection procedure is used to choose allocations. In order to reflect that laws and rules than allocations are implemented and that they involve an element of randomness because of incomplete information, selection procedures are taken to be...

In the present paper we study voting-based corporate control in a general equilibrium model with incomplete financial markets. Since voting takes place in a multi-dimensional setting, super-majority rules are needed to ensure existence of equilibrium. In a linear-quadratic setup we show that the...

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...

This article provides a study of corporate control in a general equilibrium framework for production economies. When markets are incomplete, trading assets does not allow agents to fully resolve their conflict of interest: at the market equilibrium, shareholders disagree on the way to evaluate...

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.

We consider weak preference orderings over a set An of n alternatives. An individual preference is of refinement l <=n if it first partitions An into l subsets of "tied" alternatives, and then ranks these subsets within a linear ordering. When l

This paper investigates the existence of asymmetric equilibria in a pure exchange economy with individual risks. The model is an extension of Malinvaud's (1973). Agents face identical pure individual risks: their endowments and utility functions only depend on their individual state; but there...

Indivisible units are produced with increasing marginal costs. Under Average Cost, each user pays average cost. Under Random Priority, users are randomly ordered (without bias) and successively offered to buy at the true marginal cost. Both AC and RP inefficiently overproduce. RP tends to...

When aggregating individual preferences through the majority rule in an n-dimensional spatial voting model, the 'worst-case' scenario is a social choice configuration where no political equilibrium exists unless a super majority rate as high as 1-1/n is adopted. In this paper we assume that a...
