本研究探讨了在供应中断风险下，消费者的社会学习行为对其购买决策的影响，以及零售商应如何考虑这一点并优化其库存订购策略。我们开发了一种拥有两批消费者的模式。第一批消费者评估潜在的供应中断风险，并决定是否储存额外的单位供未来消费(即恐慌性购买)。他们的购买决定通过社会学习影响了第二批消费者。给出了零售商的最优库存订货策略，并在不考虑SL影响的情况下评估了零售商的利润损失。我们发现，当第一批恐慌性购买消费者的比例(我们定义为初始恐慌强度)处于中等水平时，消费者恐慌性购买和SL行为对零售商和社会福利都是有利的。相反，如果最初的恐慌强度很低或很高，SL会损害零售商的利润和整体社会福利。
This study investigates the impact of consumers' social learning (SL) behavior on their purchase decisions under supply disruption risk, and accordingly, how retailers should take this into account and optimize their inventory ordering strategy. We develop a model with two batches of consumers. The first batch of consumers evaluates the potential supply disruption risk and decides whether to stockpile extra units for future consumption (i.e., panic buying). Their purchase decisions influence the second batch of consumers via social learning. We derive the optimal inventory ordering policy for the retailer and evaluate the retailer's loss of profit if the impact of SL is not taken into consideration. We show that when the portion of panic buying consumers among the first batch (which we define as the initial panic intensity) is at a moderate level, consumer panic buying and SL behaviors can be beneficial for the retailer and the social welfare. In contrast, if the initial panic intensity is very low or very high, SL can hurt the retailer's profit and the total social welfare.
