On The Relation Among Some Definitions Of Strategic Stability

No 137, Working Papers from Department of Economics, The University of Auckland

Abstract: In this paper we examine a number of different definitions of strategic stability and the relations among them. In particular, we show that the stability requirement given by Hillas (1990) is weaker than the requirements involved in the various definitions of stability in Mertens' reformulation of stability (Mertens 1989, 1991). To this end, we introduce a new de nition of stability and show that it is equivalent to (a variant of) the definition given by Hillas (1990). We also use the equivalence of our new de nition with the definition of Hillas to provide correct proofs of some of the results that were originally claimed (and incorrectly \proved") in Hillas (1990).
