The call for papers for the 2004 ACM Conference on Electronic Commerce
is now available. I'm posting this note as my duty as a program
committee member to spread the word of the conference.
Why would an electronic commerce conference want me, a complexity
theorist, as a PC member? Electronic commerce has many surprising
connections to computational complexity. Consider complex auction
situations where different buyers wish to purchase different items
with varying needs for combinations of these auctions. One needs to
design such auctions which decisions made by the buyers, as well as
determining the winner must be computationally efficient. This in
addition to the usual needs of auctions to be revenue generating,
robust against players trying to cheat the system and other notions of
"fairness."
In a more philosophical sense, what is a large financial market but
some sort of massive parallel computation device that takes pieces of
information and produces prices for securities. How can we model and
analyze this process? Computational complexity should play a major
role in understanding this model of computing and allow us to develop
more efficient financial markets.
