报告题目：Bright Side of Diverse Market Beliefs Held by Firms
讲座内容：Suppliers sell products through a retailer to the market with uncertain demand. The retailer has access to a demand signal useful for updating forecast of market uncertainty. Suppliers can acquire the retailer’s signal, termed information sharing. Due todifferential functional roles and means of market access, firms hold diverse beliefs about market conditions. This is further aggravated as they apply privileged systems to process information and interpret market trend. We unveil the circumstances where information sharing occurs as firms hold diverse market beliefs and as they are either aware or unaware of each other’s beliefs, and explore the consequential effects on firms’ actual profits. Our results show that diverse market beliefs facilitate information sharing. Information symmetry in signals for forecast updating, achieved through information sharing, is a strategic complement to that in market beliefs. Information symmetry in firms’ believed market uncertainty does not improve actual profits for all firms simultaneously, but that in firms’ believed market size can. Information sharing is more likely to occur as suppliers can screen the market belief held by the retailer (through its decision on payment acceptance for signal disclosure), but is less likely so as the retailer calculatedly reports its market belief. This is a joint work with Zhongyuan Hao.
