The original published version can be found at: http://dx.doi.org/10.1016/S0899-8256(02)00548-1.Some results in the monotone comparative statics literature tell us that if a parameter increases, some old equilibria are smaller than some new equilibria. We give a sufficient condition such that at a new parameter value every old equilibrium is smaller than every new equilibrium. We also adapt a standard algorithm to compute a minimal such newer parameter value and apply this algorithm to a game of network externalities. Our results are independent of a theory of equilibrium selection and are valid for games of strategic complementarities.en-USComparative staticsComputing equilibriaStrategic complementaritiesSupermodular gamesArticle10.1016/S0899-8256(02)00548-1openAccess
