The Multiproduct Firm, Quality Choice, and Regulation
研究垄断企业面对异质消费者时如何扭曲产品质量，并评估最低质量标准、最高价格管制和回报率管制三种规制手段的效果。
A monopolist facing a market of heterogeneous consumers will distort the quality a rray. This paper explores three regulatory remedies-minimum quality s tandards (MQS), maximum price regulation (MPR), and rate of return re gulation (RORR)-that can counteract this distortion. MQS and MPR rais e the quality offered to consumers with a low willingness-to-pay for quality. While MQS have no effect on the quality offered to consumers with a high willingness-to-pay, MPR decreases the quality offered to this group. If production of high- (low-) quality goods is capital i ntensive, RORR increases (decreases) the quality offered to both grou ps. Copyright 1988 by Blackwell Publishing Ltd.
