Direct Welfare Analysis of Relative Price Regulation

Author

Listed:
  • John Vickers

Abstract

The paper synthesizes and develops the welfare analysis of regulating relative prices, for example price differences, of which banning price discrimination is a special case. Welfare results are derived directly by convexity arguments using functions of welfare levels. The method is also used to obtain results about effects on consumer surplus.
