A biweekly seminar series on Economics, Networks, and Security is being held at the University of Cambridge during fall 2003. This website maintains abstracts of the speakers' presentations and research papers about their topics of discussion. Of the five seminars scheduled, papers for three have been posted online and the remaining two will likely be available in the near future. The first paper outlines the concept of trusted computing and discusses the implications for public policy. The second paper is based on economical aspects of intellectual property, but a less technical resource is also given and is titled Digital Goods in the New Economy. Lastly, the facets of e-commerce and its relation to security is the basis for the third paper. [CL]
