Abstract
In this article, we consider how important developments in game the-
ory have contributed to the theory of anization. Our goal is
not to survey the theory of anization; rather, we consider the
contribution of game theory through a careful discussion of a small number
of topics within the anization …eld. We also identify some
points in which developments in the theory of anization have
contributed to game theory. The topics that we consider are: commitment
in two-stage games and the associated theories of strategic-trade policy and
entry deterrence; asymmetric-information games and the associated theo-
ries of limit pricing and predation; repeated games with public moves and
the associated theory of collusion in markets with public demand ‡uctua-
tions; mixed-strategy equilibria and puri…cation theory and the associated
theory of sales; and repeated games with imperfect monitoring and the
associated theory of collusion and price wars. We conclude with a gen-
eral assessment concerning the contribution of game theory to industrial
organization.
1. Introduction

anization theory literature is now presented almost exclusively in

terms of game theoretic models. But the relationship is not totally one-sided.
First, the needs of anization fed back and exerted a general in‡uence
on the agenda of game theory. Second, speci…c ideas that grew out of problems in
anization gained independent importance as game theoretic topics
in their own right
