The Illusion of Victory: How Gambling Affinity Influences Extended-Warranty Decisions
研究发现，许多购买延长保修的消费者期望它能带来正回报，这种“胜利的幻觉”在赌博偏好较强的人群中更明显，且低收入消费者购买更多，对消费者福利有重要影响。
An extended warranty is a commonly purchased financial product that involves the promise to reimburse the buyer of a durable good for repairs during the period of coverage. Although such product repairs are infrequently needed, nine studies (including three in the Web Appendix ; six preregistered; N = 3,304) show that many consumers who choose to buy extended warranties expect that purchasing the warranty will ultimately prove to be a financially savvy decision (i.e., will provide a positive return on investment). Further, this tendency is more pronounced among consumers with greater affinity for gambling. The authors argue that this “illusion of victory” is a major factor in extended-warranty purchases, with important implications for consumer welfare. Given that extended warranties are disproportionately purchased by low-income consumers, societal benefits may be realized if financial products that protect consumers from small losses (vs. large, catastrophic losses) are clearly distinguished and governed by separate regulations.
