TEXTBOOK

The principal textbook is General Equilibrium Theory: An Introduction by Ross Starr. We'll be using the draft second edition --- it will be available on the web for this class. The first edition paperback, Cambridge University Press, 1997, should be available in the campus bookstore --- though you should not need it; it should be pretty inexpensive.
