2021年4月19日下午，现代供应链管理研究院第五十二期学术论坛如期举行。本次论坛的主讲人是南洋理工大学南洋商学院助理教授汤勤深，其报告题目为“Supply Chain Performance with Target-Oriented Firms”。
We study a supply chain in which a supplier sets the wholesale price and a retailer responds with an order quantity. Both the two firms can be either risk-neutral—maximizing the expected profit—or target-oriented, which is to maximize her/his ability to reach a target profit. We provide a strong support for firms' target-based preference and the linear target formation model through a survey as well as analyzing company data. With the firms' target-oriented behavior evaluated by a CVaR-satisficing measure, we apply a game theoretical framework to investigate how the target-based preference affects supply chain performance. We find that, a firm, be it a supplier or a retailer, is always hurt by its target-based preference, but can benefit from its trading partner's target-based preference. A risk-neutral supplier, for example, can sometimes reap the whole supply chain's profit if the retailer is target-oriented; and a target-oriented supplier always performs better with a target-oriented retailer than a risk-neutral one. Furthermore, a target-oriented retailer or/and supplier can help alleviate the double marginalization effect, and sometimes help the supply chain achieve the same efficiency level as in a risk-neutral centralized system, with just a wholesale price contract. Another important finding is that if both firms are target-oriented, then the supply chain can have a higher expected profit under a decentralized system than a centralized one. This contrasts to the case when both firms are risk-neutral. We also investigate the role of outside option and information asymmetry and find that both can alleviate the retailer's disadvantage of being target-oriented.
