We provide a tractable characterization of the sharp identification region of the parameters ø in a broad class of incomplete econometric models. Models in this class have set valued predictions that yield a convex set of conditional or unconditional moments for the observable model variables....

Is the behavior of people consistent with the predictions of the Nash equilibrium and, in particular, the Minimax hypothesis? The existing literature have not reached a consensus about the answer to this question. This paper studies whether the soccer players involved in a penalty kick behave...

We study a simultaneous, complete-information game played by p = 1 P agents. Each p has an ordinal decision variable Y p ∈ A p ={ 0 1 M p} , where M p can be unbounded, A p is p’s action space, and each element in A p is an action , that is, a potential value for Y p . The collective action...
