Monopoly Price Dispersion Under Demand Uncertainty
当垄断者在需求未知前定价，可能设定多个价格并限制低价供应。本文在标准垄断定价模型中引入需求不确定性和价格刚性，发现最优策略是设定两个价格并限制低价购买量。
When a monopolist sets its price before its demand is known, then it may set more than one price and limit the availability of its output at lower prices. This article adds demand uncertainty and price rigidities to the standard model of monopoly pricing. When there are two states of demand and the ex post monopoly price is greater when demand is high then the monopolist's optimal ex ante pricing strategy is to set two prices and limit purchases at the lower price.
