The Threshold-Crossing Effect: Just-Below Pricing Discourages Consumers to Upgrade
研究发现，当基础产品价格略高于整数阈值时，消费者更可能升级并花费更多，因为升级选项显得更便宜；而略低于阈值的定价反而抑制升级。
Abstract Managers often set prices just-below a round number (e.g., $39)—a strategy that lowers price perceptions and increases sales. The authors question this conventional wisdom in a common consumer context: upgrade decisions (e.g., whether to upgrade a rental car or hotel room). Seven studies—including one field study—provide empirical evidence for a threshold-crossing effect. When a base product is priced at or just-above a threshold, consumers are more likely to upgrade and spend more money (studies 1–3) because they perceive the upgrade option as less expensive (study 4), and they place less weight on price (study 5). Testing theoretically motivated and managerially relevant boundary conditions, studies find that the threshold-crossing effect is mitigated under sequential choice (study 6) and when an upgrade price crosses an upper threshold (study 7). These studies demonstrate that a small increase in price on a base product can decrease price perceptions of an upgrade option and, thus, increase consumers’ likelihood to upgrade. Results suggest that just-below pricing, while sometimes advantageous at first, may not always be an optimal strategy for managers trying to encourage consumers to ultimately choose an upgrade option.
