MONOPOLY, EFFICIENCY: A monopoly generally produces less output and chargers a higher price than would be the case for perfect competition. In particular, the price charged by a monopoly is higher than the marginal cost of production, which violates the efficiency condition that price equals marginal cost. Monopoly is inefficient because it has market control and faces a negatively-sloped demand curve.Monopoly does not efficiently allocate resources. In fact, monopoly (if left unregulated) is generally considered the most inefficient of the four market structures. The reason for this inefficiency is found with market control. As the only seller in the market, the negatively-sloped market demand curve is THE demand curve facing the monopoly. If buyers want to buy, they must buy from the monopoly. The negative slope of the demand curve means that the price charged by the monopoly is greater than marginal revenue. As a profit-maximizing firm that equates marginal revenue with marginal cost, the price charged by monopoly is greater than marginal cost. The inequality between price and marginal cost is what makes monopoly inefficient. Profit Maximization
A typical profit-maximizing output determination using the marginal revenue and marginal cost approach is presented in this diagram. Feet-First Pharmaceutical maximizes profit by producing output that equates marginal revenue and marginal cost, which is 6 ounces of Amblathan-Plus in this example. The corresponding price charged is $7.50. This profit-maximizing production is not efficient. In particular, the price is $7.50, but the marginal cost is only $4.50. Society is producing and consuming a good that it values at $7.50 (the price). However, in so doing, society is using resources that could have produced other goods valued at $4.50 (the marginal OPPORTUNITY cost). Society gives up $4.50 worth of value and receives $7.50. This is a good thing. It is so good, that society should do more. However, the monopoly is not letting this happen. Feet-First Pharmaceutical is not devoting as many resources to the production of Amblathan-Plus as society would like. An Efficient AlternativeThe degree of monopoly inefficiency can be illustrated with a comparison to perfect competition. Such a comparison is easily accomplished by clicking the [Perfect Competition] button. A primary use of perfect competition is to provide a benchmark for the comparison with other market structures, such as monopoly.A comparison between monopoly and perfect competition indicates:
