We study the stability of Nash equilibria for games in normal form, parameterized by continuous and quasi-concave payoffs and compact convex strategy sets in Euclidean spaces. And we establish an existence theorem for essential connected components of Nash equilibria, which includes corresponding results in the literature as special cases. (C) 2009 Elsevier Ltd.
