 abstract = {This paper studies nonparametric identification in binary choice games of complete information. We allow for correlated unobservables across players. We propose conditions under which the binary choice game is a so-called potential game and impose that the selected equilibrium maximizes its associated potential function. Our framework is formally equivalent to a multinomial choice demand model where a consumer can elect to purchase any bundle of products. We present a separate identification result for two-player games that does not rely on equilibrium selection.},
