報(bào)告1：Frequent product introductions emphasize the importance of product rollover strategies. With single rollover, when a new product is introduced, the old product is phased out from the market. With dual rollover, the old product remains in the market along with the new product. Anticipating the introduction of the new product and the potential markdown of the old product, strategic customers may delay their purchases. We study the interaction between product rollover strategies and strategic customer purchasing behavior and find that single rollover is more valuable when the new product's innovation is low and the number of strategic customers is high. Interestingly and counter to intuition, the firm may have to charge a lower price for the old product as well as receive a lower profit with a higher value disposal (outside) option for the old product under single rollover. Facing a market composed of both strategic and myopic customers, the firm does not necessarily reduce the stocking level as more myopic customers become strategic.
報(bào)告2：We study mixed leadership differential games in which a player acts as a leader for some decisions and as a follower for the remaining ones. We partition all decisions into lead and follow-up decisions in the sense that the follow-up decisions are obtained simultaneously as the optimal responses to the lead decisions. Clearly, this involves both Nash and Stackelberg steps. Furthermore, given the optimal responses, the lead decisions are made simultaneously also as a Nash step. Thus, the procedure of finding a feedback Stackelberg equilibrium of the game requires Nash and Stackelberg steps in a nested fashion. We apply the procedure to a cooperative advertising supply chain where the manufacturer and the retailer decide their national and local advertising efforts for selling a product as the follow-up decisions, in response to the participation rates for these efforts provided by the retailer and the manufacturer as their lead decisions, respectively. We discuss the insights obtained from the results. A second application of the procedure to a linear-quadratic game concludes the paper.
