Product Life Cycle Theory And The Maturation Of The Internet, Christopher S. Yoo Nov 2009

Product Life Cycle Theory And The Maturation Of The Internet, Christopher S. Yoo

Faculty Scholarship at Penn Law

Much of the recent debate over Internet policy has focused on the permissibility of business practices that are becoming increasingly common, such as new forms of network management, prioritization, pricing, and strategic partnerships. This Essay analyzes these developments through the lens of the management literature on the product life cycle, dominant designs, technological trajectories and design hierarchies, and the role of complementary assets in determining industry structure. This analysis suggests that many of these business practices may represent nothing more than a reflection of how the nature of competition changes as industries mature. This in turn suggests that network neutrality ...


Network Neutrality After Comcast: Toward A Case-By-Case Approach To Reasonable Network Management, Christopher S. Yoo Feb 2009

Network Neutrality After Comcast: Toward A Case-By-Case Approach To Reasonable Network Management, Christopher S. Yoo

Faculty Scholarship at Penn Law

The Federal Communications Commission’s recent Comcast decision has rejected categorical, ex ante restrictions on Internet providers’ ability to manage their networks in favor of a more flexible approach that examines each dispute on a case-by-case basis, as I have long advocated. This book chapter, written for a conference held in February 2009, discusses the considerations that a case-by-case approach should take into account. First, allowing the network to evolve will promote innovation by allowing the emergence of applications that depend on a fundamentally different network architecture. Indeed, as the universe of Internet users and applications becomes more heterogeneous, it ...


Network Neutrality, Consumers, And Innovation, Christopher S. Yoo Aug 2008

Network Neutrality, Consumers, And Innovation, Christopher S. Yoo

Faculty Scholarship at Penn Law

In this Article, Professor Christopher Yoo directly engages claims that mandating network neutrality is essential to protect consumers and to promote innovation on the Internet. It begins by analyzing the forces that are placing pressure on the basic network architecture to evolve, such as the emergence of Internet video and peer-to-peer architectures and the increasing heterogeneity in business relationships and transmission technologies. It then draws on the insights of demand-side price discrimination (such as Ramsey pricing) and the two-sided markets, as well as the economics of product differentiation and congestion, to show how deviating from network neutrality can benefit consumers ...
