Course Goals

This is a first course in the economic analysis of information networks for master's students in the Service Engineering Degree Program. It may also be of interest to students in the Policy and Planning Science Degree Program, as well as students of computer science and management of technology. This is not a technical course in information networks. (Several are offered from different points of view in the Department of Policy and Planning Science as well as several other departments.) The focus is on (1) understanding the relationship between behavior of individual decision-makers and that of the networks they participate in, (2) using that theory to make inferences about motivation and predictions of future behavior, and (3) determining how networks can provide economic value-added (and how much value).

Students passing this course are expected to be able to diagram networks, explain the relationships among several networks involving the same actors or links, and assess their economic or business value.

The previously announced syllabi are available from the University's KDB site, and copies are provided here. Note: The actual content and order of presentation has changed in the process of preparation.
