Optimal Nonuniform Prices
研究价格随购买量变化的非线性定价方案，分析福利最优定价与Ramsey最优统一定价的关系，并刻画定价方案中出现向上或向下跳跃的条件，对税收、保险和激励问题有参考价值。
We consider optimal nonuniform pricing schedules, where the price depends upon the amount purchased. Such schedules are regularly used by public utilities and other services. Welfare-optimal nonuniform prices are related to the theory of optimal uniform prices developed by Ramsey. We characterize situations in which upward or downward discontinuities in pricing schedules are optimal. Our results are applicable to a number of related problems, including optimal taxation, insurance, and incentives.
