Abstract

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 production plans which ly outside the market span, and the objective function of the firm is not well defined. Two ways of resolving these conflicts are compared here. The first one (see, e.g., Dreze 1974 and Grossman & Hart 1979) consists in allowing sidepayments between shareholders. The second one (see, e.g., Dreze 1985 and DeMarzo 1993) relies on majority voting in the assembly of shareholders; a stable production plan is one which cannot be overruled by a majority of shareholders. Since voting occurs in a multi-dimensional setup super majority rules are needed to ensure existence of such "political" equilibria. The most interesting equilibria are those which are stable with respect to the super majority rule with smallest rate. The present paper provides a framework where these two approaches yield the same equilibria.
