Regulating a Monopolist with Unknown Demand
研究当企业比监管者更了解需求时，如何设计最优规制政策。若边际成本随产出递增，监管者可引导企业利用私有信息服务社会利益；若递减，则无法获益，只能设定单一价格。
Optimal regulatory policy is derived in a setting where the firm has better knowledge of demand than the regulator. When marginal production costs increase with output, the regulator can induce the firm to use its private information entirely in the social interest. When marginal costs decline with output, however, the regulator is unable to derive any benefit from the firm's superior knowledge, and a single price is established that is invariant to demand.
