单选题 Monopolists will maximize profit by producing at an output level where which of the following conditions exists? A. Price = marginal revenue = marginal cost. B. Price = demand = marginal revenue = marginal cost. C. Marginal revenue = marginal cost ＜ price.

【正确答案】 C

【答案解析】To maximize profit, monopolists will expand output until marginal revenue equals marginal cost. Price will be greater than marginal revenue because a monopolist faces a downward sloping demand curve.
