Term collusion and efficiency Definition: Colluding oligopolistic firms generally produce less output and charge a higher price than would be the case for a perfectly competitive industry. In essence, colluding oligopolistic firms function just as if a market were monopolized. The price charged by the colluding firms is higher than the marginal cost of production. The equality between price and marginal cost is THE key indication that resources are allocated efficiently and that society's resources are being used to generate the highest possible level of satisfaction. Because the colluding firms control the market like a monopoly, the market demand curve is THE demand curve for the colluding firms's. With a negatively-sloped demand curve, price is greater than marginal revenue. And because a profit-maximizing firm equates marginal revenue with marginal cost, the price charged by the colluding firms when the maximize industry profit is greater than marginal cost.
