Abstract

An invited contribution to a symposium on “Information and Knowledge in Economics,” to appear in Econ Journal Watch. Topics discussed include the distinction between information and knowledge; awareness; logical omniscience; the cost of calculation; semantic and syntactic models of knowledge, and the equivalence between them; and common knowledge of the model. Finally, some aspects of the symposium contributions of Ken Binmore, Jim Friedman, and Eric Rasmusen are discussed.
