EXPRESS: Cushioning the Blow: Reducing Customer Attrition in Response to Price Increase Notifications
通过与加拿大仓储公司合作开展实地实验和在线实验，研究发现市场理由比成本和质量理由更能减少客户流失，原因是市场理由提高了客户的转换成本感知。
Price increases can elicit a range of negative customer responses, from dissatisfaction to complaints, exits, and even boycotts. Practicing managers and academics agree that firms must justify their price increases, and consider three justification types—cost, market, and quality—as the primary means to do so. Yet, the comparative effectiveness of these justifications in reducing customer attrition remains unknown. The authors collaborated with a multi-site Canadian storage provider to design and implement three experiments. Study 1 is a randomized field experiment involving 10 cohorts of 1,626 actual customers, demonstrating the effects of cost, market, and quality justifications on customer attrition, and variations in these effects across levels of justification concreteness, and price increase percentage and dollar amount. In marked contrast to prior practitioner recommendations and academic research, market justification is found to result in the lowest customer attrition. The authors use heterogeneity in the effects of the justifications to demonstrate that customers’ switching costs perceptions explain this finding. Studies 2 and 3 are online scenario experiments that further examine how these justifications affect customers’ switching costs and fairness perceptions. Together, these studies provide important insights to firms seeking to “cushion the blow” of price increases.
