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(More)
