Tighter Average Revenue Regulation can Reduce Consumer Welfare
研究了在两个市场经营的垄断企业受平均收入约束时，更严格的监管可能导致一个市场价格上升，并可能降低总消费者剩余。
A monopolist producing for two markets is subject to an average revenue constraint, a form of regulation which is relevant to some U.K. utilities. Where marginal costs of serving the two markets differ, tighter regulation may cause one of the prices to rise as shown by I. Bradley and C. Price (1988). A simple linear example demonstrates that total consumer surplus may fall as regulation becomes more stringent. Copyright 1995 by Blackwell Publishing Ltd.
