第12章 行为歧视的社会经济效应

Sobel, “Costly Price Discrimination,”EconomicsLetters 99, no. 1（2008）: 206-208,http://www.peterleeson.com/Costly\_Price\_Discrimination.pdf; 文中提到，“我们之所以说‘完美的价格歧视的社会效率低下’，是因为企业需要在实施价格歧视的过程中负担种种开支。这些成本包括细分客户、识别需求弹性、防止转售。不论是在什么行业，这些成本都不菲。由此，也不是所有的企业的会采取如此的定价策略。（学术界）不该在现有的价格歧视理论中忽视这些交易成本。瓦里安（Varian）曾指出，‘一个完整的价格歧视社会福利效应分析不能忽视这种定价策略在施行过程中的交易成本’”。

1. 有一点值得注意，在一项有关航空票价的研究中，研究者发现航空公司的实际策略符合他们对其定价模式的设想：当飞特定航线的航空公司增多时，航空公司会为需求价格弹性较高的旅客提供更优惠的票价，与此同时却维持对需求价格弹性低的旅客的票价。详见：J. Stavins,“Price Discrimination in the Airline Markets: The Effect of MarketConcentration,” Review of Economics and Statistics 83（2001）:200。

1. 比方说，医药行业市场，“在低收入水平国家，当地的民众会仅仅因为价格问题而不愿购买那些药效显著的药剂。这样看来，这些地方更需要价格歧视，特别是大规模的降价销售”。详见：JudithL. Wagnerand Elizabeth McCarthy, “International Differences in Drug Prices,” AnnualReview of Public Health 25（2004）: 475。

1. 同样还是医药行业市场的例子，由Jerry Hausman和JeffreyK.MacKie-Mason开展的一项研究揭示，由于价格歧视带给企业研发活动的积极影响，整体社会福利效应会在动态变化中得到改善。详见：Jerry A. Hausman and Jeffrey McKie-Mason, “Price Discrimination andPatent Policy,” RAND Journal of Economics 19（1988）: 253。当企业能够通过价格歧视来负担研发活动造成的高昂前期投入成本时，他们也会有更大的创新动力：“如果考虑到动态激励，价格歧视也可以确保企业通过赚取可观的回报来维持长期的研发投资热情。”Papandropoulos,“How Should Price Discrimination Be Dealt with by CompetitionAuthorities?”如果企业具备创新能力，那么创新的动力将被由创新带来的财务收益点燃。这一经济框架“经常与著名经济学家约瑟夫·熊彼特（Joseph Schumpeter）教授联系在一起”，他建议说：“拥有市场力量的公司应该最有动机创新，这是由他们的经营规模与市场地位决定的。”详见：D. L. Weisman and R. B.Kulick, “Price Discrimination, Two-Sided Markets, and Net Neutrality Regulation,” Tulane Journal ofTechnology and Intellectual Property 13（2010）: 81,https://www.researchgate.net/profile/Dennis\_Weisman/publication/22830799Sided\_Markets\_and\_Net\_Neutrality\_Regulation/links/0deec5187eadf2a5c800

1. Josh Wright, “Price Discrimination Is Good, Part I,” Truth on theMarket（November 30, 2008）,http://truthonthemarket.com/2008/11/30/price -discrimination-is-good-part-i/.一般来讲，这种理念与诺贝尔经济学奖获得者肯尼斯·阿罗（KennethArrow）不无关系，他提出“由创新带来的业务扩张多是来源于竞争对手的拱手相让，而寡头企业则可能在很大程度上蚕食自己的业务”。详

见：Weisman andKulick, “Price Discrimination, Two-Sided Markets, and Net Neutrality Regulation.”

1. “价格歧视之所以会加剧竞争的原因在于：在统一定价策略下，企业只会就边际消费者展开争夺；但通过价格歧视，企业可以争夺市场中的所有客户，包括那些对竞争对手有着强烈忠诚度的顾客。”详见：Papandropoulos, “How Should Price Discrimination Be Dealt with byCompetition Authorities?”

1. 以欧洲的汽车租赁行业为例。2014年，欧盟委员会致函六家国际汽车租赁公司，包括Avis、Europcar和Hertz。原来，这几家租车公司会针对顾客的国别而进行差别化定价。详见：“Car HirePrices ‘UnfairlyVary’ across the EU,” BBC News（August 12,2014）,http://www.bbc.co.uk/news/business-28756674。美国司法部在2003年的一起并购案中也注意到了这个问题。该案关乎北加州的两大临床实验室测试服务供应商——Quest Diagnostics公司与Unilab公司。“虽然这些服务的购买者不能将服务转售给其他客户并获取经济价值，但服务供应商可以根据医生的供职地确定这些客户还可选择的竞争替代品的多寡。这说明，并购促成后的这个垄断者可以基于客户的所在地进行价格歧视。”详见：Federal Trade Commission and U.S.Department of Justice,Commentary on the Horizontal Merger Guidelines（March 2006）, 8,http://www.justice.gov/atr/commentary-horizontalmerger-guidelines。

1. Papandropoulos, “How Should Price Discrimination Be Dealt withby Competition Authorities?”“价格歧视也可以成为实施掠夺性定价的手段。事实上，它还可以降低掠夺性定价的实施成本，从而让在行业中占支配地位的企业通过定价歧视实现掠夺性定价的暴利。
