解题思路:了解垄断的特点,
Answer (A) is correct . A monopoly consists of a single firm with a unique product. Such a firm has significant price control. For profit maximization, it increases production until its marginal revenue equals its marginal cost (unless marginal revenue is less than average variable cost, which will cause the firm to shut down). When a monopoly exists, consumers will face higher prices and lower output than in perfect competition.垄断下的利润最大点也是边际利润等于边际成本.
Answer (B) is incorrect because The monopolist is in control of the quantity supplied. Thus, the supply can be limited to produce the profit-maximizing price.垄断下对产量有控制,所以产量越少,价格越高.
Answer (C) is incorrect because A monopolist will increase supply as long as the demand curve is inelastic. Inelasticity means that an increase in price will cause a less-than- proportionate decline in demand.
Answer (D) is incorrect because There is only one price when a monopoly exists.
