A new paper on the economics of network neutrality

Nicholas Economides† and Benjamin E. Hermalin have a new paper (pdf), coming out in the Rand Journal of Economics, summarized here, here is the abstract:

Pricing of Internet access has been characterized by two properties: Parties are directly billed only by the Internet service provider (isp) through which they connect to the Internet. Pricing, moreover, is not contingent on the type of content being transmitted. These properties define a regime known as “network neutrality.” In 2005, some large isps proposed that application and content providers directly pay them additional fees for accessing the isps’ residential clients, as well as differential fees for prioritizing certain content. We analyze the private and social incentives to introduce such fees when the network is congested and more traffic implies greater delays. We derive conditions under which network neutrality would be welfare superior to any feasible scheme for prioritizing service. Extending our analysis to encompass isps’ incentives to invest in more bandwidth, we show that the ability to price discriminate increases their incentives to invest. In terms of overall welfare, we show the additional investment may or may not offset any static inefficiency associated with discrimination.

This strikes me as a funny way to put the point.  Might the authors also have written?: “A strict welfare calculation is indeterminate in the theory of price discrimination, yet the standard presumption is that price discrimination is welfare-improving.  That is all the more likely to be the case when investment in new capacity, and usage, is endogenous”?

For the pointer I thank Richard Harper.
