Limited Time Offer and Consumer Search
研究了限时优惠这一常见但理论上未被充分探讨的销售策略，通过构建搜索模型分析其在价格可观察市场中对消费者搜索顺序和社会福利的影响。
This paper examines a widely observed yet theoretically underexplored sales tactic: the limited time offer. By focusing on price-directed search markets, we offer a novel perspective on the application of limited time offers by firms and their implications for social welfare. We build a search model where firms advertise dynamic pricing to influence a consumer’s search order. Across various model settings, we demonstrate that limited time offers serve as the most effective pricing tool for firms to achieve search prominence or implement search discrimination, with their impact on social welfare varying depending on the market context. In particular, although existing literature suggests that limited time offers are anticompetitive in markets where prices are unobservable presearch, our findings show that, in markets with observable prices, limited time offers can enhance social efficiency in certain cases by facilitating a socially optimal search order.
