世界創造主としての人間に関する理論？

先週8日のミクロ経済学・ゲーム理論セミナーは、東大の松井先生でした。タイトルからも分かるように難解だけどおもしろい話でした。

講演者　：　松井　彰彦　[東京大学大学院経済学研究科　教授]
演　題　：　A Theory of Man as a Creator of the World
＜ abstract ＞
The present paper proposes a theory of man, wherein man constructs models of the world based on past experiences in social situations. The present theory considers experiences, or chunks of impressions, as primitives instead of an “objective” game, which is assumed to be given in the standard game theory. Agents construct models of the world based on direct and indirect experiences. Each model comprises a structural part and a factual part. The structural part is represented as a game, while the factual part is represented as a strategy profile of this game. In constructing a model, an agent might use certain axioms, for example, coherence, according to which the model should be able to explain his or her own experiences; conformity to a solution concept; and minimality with respect to some simplicity measure. A few applications are presented to demonstrate how this theory works.

この話は、金子先生との研究にあるInductive Game Theory(帰納的ゲーム) の延長線上にある話なんですが、詳細は「また後で」。
