主   题:Sourcing Strategies in the Presence of Social Comparisons, Random Yields and Supplier Competition with Limited Capacity

主讲人:Yulan Wang 香港理工大学教授

主持人:田林 复旦大学管理学院教授

摘   要:

Dual sourcing is a strategy commonly adopted by original equipment manufacturers (OEMs) to diversify their supply base, secure capacity supply, and induce competition between suppliers. However, because the sourced components are produced by different suppliers, the final products might differ in quality. Consumers may become dissatisfied if they receive a lower quality product and conduct social comparison with others. In this paper, we examine how such consumer aversion to disadvantageous inequality affect the OEM’s sourcing decision and suppliers’ wholesale price decision. We show that consumer aversion to disadvantageous inequality reduces the OEM’s incentive to dual source and intensifies competition between suppliers, thereby hurting suppliers but benefiting the OEM. Consumers, however, can be either hurt or benefited by their inequality aversion. When the degree of inequality aversion is sufficiently large, the OEM is forced to switch from dual sourcing to single sourcing and eliminate inequality between consumers. We further show that when the suppliers have insufficient capacity, a pure strategy Nash equilibrium may not exist for the supplier's wholesale pricing game. Nonetheless, we can characterize a mixed strategy wholesale price equilibrium and show that limited capacity levels can alter the role of consumer inequality aversion.
