This site is run by Hal Varian. One section contains information about the Department of Economics at the University of Michigan. But the most interesting section contains a wealth of information on the "Economics and the Internet". It contains a wealth of information on the union of the Internet and economics, very broadly defined. There are topics on digital commerce, congestion pricing of networks, digital cash, etc. (Most of the information is on the WWW page; the gopher will probably be phased out in the future.) (Hal Varian kindly supplied most of this information.)
