近日，太阳成集团tyc7111cc邹至庄经济研究院、太阳成集团tyc7111cc经济学系陈德麟助理教授独立完成的学术论文“Quality Strategies in Network Markets”在UTdallas24排名期刊之一Management Science在线发表。
This paper studies network market problems in which firm(s)/platform(s) sets quality in addition to price. A well-established result in the network economics literature is that a profit-maximizing firm concerns only how quality is valued by the marginal consumer but not by inframarginal consumers, aka the Spence effect/distortion. For markets with strong network effects under which multiple market-tipping equilibria exist, I show that the validity of the previous result depends on the choice of the equilibrium selection criterion. Precisely, I show that all criteria commonly used in this literature give rise to the Spence effect, whereas the well-justified risk dominance criterion in game theory and its generalizations do not. Novel quality strategies are derived based on the latter criteria.（论文全文内容阅读请点击：https://pubsonline.informs.org/doi/10.1287/mnsc.2023.4792）
