Noise-independent selection in global games and monotone potential maximizer: A symmetric 3×3 example

► We study the relation between the global game and the generalized potential game approaches. ► We provide an example of a symmetric 3×3 supermodular game that has no monotone potential maximizer (MP-maximizer). ► The example has a noise-independent selection in global games. ► Thus, MP-maximizer is not a necessary condition for the noise-independent selection.
