	abstract = {We develop an elasticity index of a strategic game. The index measures the robustness of the set of rational outcomes of a game. The elasticity index of a game is the maximal ratio between the change of the rational outcomes and the size of an infinitesimal perturbation. The perturbation is on the players{\textquoteright} knowledge of the game.The elasticity of a strategic game is a nonnegative number. A small elasticity is indicative of the robustness of the rational outcomes (for example, if there is only one player the elasticity is 0), and a large elasticity is indicative of non-robustness. For example, the elasticity of the (normalized) n-stage finitely repeated prisoner{\textquoteright}s dilemma is at least exponential in n, as is the elasticity of the n-stage centipede game and the n-ranged traveler{\textquoteright}s dilemma. The concept of elasticity enables us to look from a different perspective at Neyman{\textquoteright}s (1999) repeated games when the number of repetitions is not commonly known, and Aumann{\textquoteright}s (1992) demonstration of the effect of irrationality perturbations.},
