First published Sat Jan 25, 1997; substantive revision Sun Sep 3, 2023
Game theory is the study of the ways in which interacting choices of economic
agents produce outcomes with respect to the preferences (or utilities) of those
agents, where the outcomes in question might have been intended by none of the
agents. The meaning of this statement will not be clear to the non-expert until each
of the italicized words and phrases has been explained and featured in some
examples. Doing this will be the main business of this article. First, however, we
provide some historical and philosophical context in order to motivate the reader for
the technical work ahead.
