Outline of Final Research Achievements

The purpose of this research project is to examine the effect of conformism in financial markets by using both theoretical and experimental approach. Conformism can represent bivariate utility function, one is own consumption and the other is group consumption. Thus, we consider financial markets where investors maximize the expected value of bivariate utility function, and determine conditions in which the investment in risk assets monotonically decreasing for investors with bivariate utility function. By interpreting the condition for social preference, we can understand how conformism affects financial markets. In experiment, conformism can be interpreted as social image. We examine the effect of social image using risky dictator game.

Academic Significance and Societal Importance of the Research Achievements

金融経済学の分野では期待効用が支配的な分析道具である。しかし、期待効用の説明力が不十分であることはよく知られており、記述的な意思決定の道具としての限界はコンセンサスがある。そのため、期待効用の記述的な弱点をカバーした非期待効用が開発されてきた。それらの多くは本研究で用いた二変数効用関数の形式で書くことができるので、一般的な二変数効用関数を用いた本研究の成果は行動経済学・行動ファイナンスの理論的な部分の貢献がある。また、その二変数効用関数は社会選好として与えられており、このような形で現実と理論との関連付けにも成功している。
