讲座简介：

(1) Problem definition: The extant literature has independently discussed wholesale price discrimination and price-matching guarantees (PMGs); however, it has been mute on the interaction between retailers' PMGs and manufacturers' discriminatory wholesale pricing.

(2) Academic/Practical relevance: In practice, numerous retailers are implementing PMGs. On the other hand, wholesale price discrimination has been widely practiced by manufacturers in some markets, while it is banned in others.

(3) Methodology: We utilize game theory to explore the interaction between the retailers' equilibrium PMG and pricing decisions and the manufacturer's optimal wholesale pricing strategies in a supply chain model with one manufacturer and two retailers.

(4) Results: If wholesale price discrimination is banned, then retailers tacitly collude by offering PMG. However, the collusive role of PMGs subsides if the manufacturer may implement discriminatory wholesale pricing. Therefore, a ban on wholesale price discrimination in an industry where retailers can offer PMGs reduces supply chain efficiency, consumer welfare, and social welfare. The negative impact of PMGs arising from banning wholesale price discrimination grows stronger with the degree of retailer asymmetry, and is more likely to happen when retailers differ in operational efficiency rather than market efficiency. Under a regulation against discriminatory wholesale pricing with retailer asymmetry, there exists a Pareto zone such that all firms prefer that only one of the two retailers offers PMG. Moreover, the presence of more uninformed customers reduces the negative impact of banning wholesale price discrimination, and it is more likely for PMGs to prevail if the retailers can delay their PMGs decisions to be after wholesale price decisions.

(5) Managerial implications: Our findings suggest against a ban on wholesale price discrimination in industries where retailers can offer PMGs in terms of supply chain profits, consumer and social welfare, although such a ban can be beneficial when PMGs are not practiced。
