An economy with two dates is considered, one state at the ¯rst date and a ¯nite number of states at the last date. Shareholders determine production plans by voting { one share, one vote { and at ½-majority stable equilibria, alternative production plans are supported by at most ½ £ 100...

A general equilibrium model with uncertainty and production externalities is studied. In absence of markets for externalities, we look for governances and conditions under which majority voting among shareholders is likely to give rise to efficient internalization. We argue that the financial...

We consider a standard insurance economy where consumers are supposed to vote over menus of insurance contracts: A menu of contracts is majority stable if there does not exist another menu which is supported by an appropriate majority of consumers. We compute the smallest level of super majority...

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...

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...

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...

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+1) is adopted. In this paper we...

We consider weak preference orderings over a set An of n alternatives. An individual preference is of refinement ≤ n if it first partitions An into subsets of ‘tied’ alternatives, and then ranks these subsets within a linear ordering. When n, preferences are coarse. It is shown that, if...

In a simple parametric general equilibrium model with S states of nature and K · S ¯rms |and thus potentially incomplete markets|, rates of super majority rule ½ 2 [0; 1] are computed which guarantee the existence of ½{majority stable production equilibria: within each ¯rm, no alternative...

When aggregating individual preferences through the majority rule in an n-dimensional spatial voting model, the worst-case scenario is a social choice conÞguration 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...
