Economic Models of Networks


A communication network consists of a technology layer and an economic
layer. In the technology layer, devices implement protocols that follow
precisely defined rules of operation. In the economic layer, network
users and providers make decisions about usage and investments that
attempt to maximize their utility. The two layers affect each other. For
instance, the performance of the network depends on the usage and the
usage depends on the performance. Trying to analyze each layer in
isolation is similar to trying to analyze a control system while
ignoring the control loop. This talk presents some economic models of
networks to illustrate the combined study of the economic and technology
layers. In addition to describing a few general effects caused by
network externality, the talk presents a study of network neutrality,
economic aspects of security, and congestion pricing.
Jean Walrand received his Ph.D. in EECS from UC Berkeley. He is the
author of An Introduction to Queueing Networks (Prentice Hall, 1988) and

co-author of High-Performance Communication Networks (2nd ed, Morgan
Kaufman, 2000). Prof. Walrand is a Fellow of the Belgian American
Education Foundation and of the IEEE and a recipient of the Lanchester
