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.
