此次学术研讨会，来自佛罗里达大学的Yinliang Tan博士来我院进行学术交流。本次研讨会由周德明老师主持，探讨的主题是“Strategic Analysis of the Agency Model for Digital Goods.”

       摘要:  

The advent of digital goods has made a significant impact on the current traditional (physical) goods markets for items such as movies, music, video games, and books. Firms that manage both traditional and digital goods distribution channels are facing many emerging operational challenges. One of the most pivotal problems for these media related industries concerns the supply chain contract model utilized for the distribution of digital goods alongside their traditional counterparts. Recently, the agency model exploited by publishers in the e-book industry has been highlighted in the press as a result of the U.S. Department of Justice’s (DOJ) lawsuit against Apple, Inc. Chief amongst the DOJ regulators’ complaints was that e-book prices increased and consumer surplus decreased as a direct result of the agency model. We investigate the strategic impact of the agency model in comparison with the prevalent wholesale and fixed price models by formulating a dual channel model of distribution accommodating sales of both traditional and digital goods. In contrast to the current press concerning the DOJ’s lawsuit, we find that the equilibrium price of digital goods is lower in the agency model than in the conventional wholesale model. Furthermore, the agency model can increase a firm’s profit as well as consumer surplus by mitigating the double marginalization effect within the digital goods supply chain. Finally, we also conceptualize the similarity and differences between the agency model and revenue sharing contracts.
