Rationing in a Durable Goods Monopoly
解释了均衡配给的新原因：耐用品垄断者无法承诺未来价格时，配给能减少其降价动机，从而提升折现利润。
We offer a new explanation of equilibrium rationing. As is well known, a monopolist selling a durable good and not able to commit to a price sequence has an incentive to lower the price once the consumers with the greatest willingness to pay have bought, but this induces consumers to postpone purchases. We show that rationing reduces the incentive to lower future prices and may allow the monopolist to increase his discounted profit.
