搜索市场中的产品可用性不确定
Uncertain Product Availability in Search Markets
摘要：
在许多市场上，买方对哪些公司销售产品（产品供应情况）和价格知之甚少，因此不得不花时间来获得这一信息。相比之下，卖家通常更清楚哪些竞争对手提供产品。买卖双方关于产品可得性而不仅仅是价格的信息不对称在关于消费者搜索的文献中没有得到仔细研究。我们提出了一个理论模型，将这种信息不对称的同时搜索模型。我们的主要发现是，更大的产品可用性可能会降低买家的搜索意愿，从而削弱竞争，从而损害买家。
英文摘要：
In many markets buyers are poorly informed about which firms sell the product (product availability) and prices, and therefore have to spend time to obtain this information. In contrast, sellers typically have a better idea about which rivals offer the product. Information asymmetry between buyers and sellers on product availability, rather than just prices, has not been scrutinized in the literature on consumer search. We propose a theoretical model that incorporates this kind of information asymmetry into a simultaneous search model. Our key finding is that greater product availability may harm buyers by mitigating their willingness to search and, thus, softening competition.
