非対称2人ゲームの大域的な分析とノイズの役割 : 最終提案ゲームを例にとって Global Approach to Asymmetric Two Person Games, and the Role of Noise
This paper examines dynamic models of evolutionary selection processes subjected to constant perturbations or "noise" on asymmetric two person games using the local and global approaches. Using the local approach, it is argued that payoffs in the Ultimatum Game are such that responders are more apt to be "noisy" than are proposers. As a result the learning process readily leads to outcomes that are Nash equilibria but not subgame-perfect. Using the global approach, the existence of individual tori in the perturbed system are proven.
