A Robust Methodology for Ramsey Pricing with an Application to UK Postal Services
提出一种仅需需求函数和边际成本大致范围的“最小信息”方法，检验拉姆齐价格对参数变化的敏感性，并以英国信件业务为例说明。
The policy relevance of Ramsey pricing calculations naturally turns on their robustness. This paper sets out a methodology for a 'minimal information' approach in examining the sensitivity of Ramsey prices to changes in demand and cost parameters. The 'minimal information' required for the approach to be operational is (1) a set of estimated demand functions for the products involved and (2) some idea of the 'ball-park' for marginal costs for these products. A case study of the U.K. letters business is used to illustrate the approach. Copyright 1996 by Blackwell Publishing Ltd.
