Monopoly Externalities and Non-Profit Maximising Firms

This paper provides a theory of a monopolist in general equilibrium. We assume that the firm's decisions are based on the preferences of shareholders and/or other stake-holders. We show that the monopolist will charge less than the profit-maximising price, since shareholders suffer part of the cost of a price rise if they are also consumers. If price discrimination is possible, the resulting equilibrium will be Pareto efficient. We use the model to examine the effects of increasing stake-holder representation in firms. A related result shows that a non-profit firm will produce fewer negative externalities.
