On the Optimal Pricing Policy of a Monopolist
解释垄断者如何通过随机到达的消费者和先到先得服务，采用两种价格并配给低价商品来增加利润，并指出单一定价在边际收益递减或边际成本不变时足够。
This paper presents a simple explanation of price dispersion by a monopolist assu ming only that consumers arrive in a random order and are served on a first-come-first-served basis. A firm can sometimes increase its pro fits by charging two different prices for the same good and rationing sales at the lower price. However, it is never necessary to charge m ore than two prices, and a single price is sufficient as long as eith er the marginal revenue curve is everywhere downward sloping or the m arginal cost of production is constant.
