摘要：
this paper studies a sales tactic that is commonly seen but theoretically under-explored: the limited-time offer. we argue that when consumers require time to evaluate their options, firms have an incentive to employ limited-time offers in order to influence the endogenous search order. by analyzing markets with and without competition, we demonstrate that for firms, limited-time offers are often strictly more profitable than uniform pricing for gaining search prominence, and firms with higher reservation values are more inclined to utilize limited-time offers as their optimal pricing strategy. in particular, in the equilibrium of a competitive market, the firm with the higher reservation value offers discounts within a shorter time window than its competitors, and consumers sample this firm earlier. we illustrate across various model setting shows limited-time offers serve as an effective pricing tool for firms to manipulate the search order and the impact of this mechanism on social welfare. complementing previous findings in the literature, we discover that limited-time offers may increase total welfare by inducing a more socially efficient search order compared to uniform pricing.
