In two-player games with negative (positive) spillovers it is well-known that symmetric agents both overact (underact) at the Nash equilibria. We show that for heterogeneous agents this rule of thumb has to be amended if the game features strategic substitutability.

L'article analyse l'identification non paramétrique de modèles de choix discrets dynamiques à partir des équations Bellman interprétées comme des conditions de moments.
