Speaker 1: Kazumi Shimizu
Title of talk: How Do Probability Biases Affect Ego Utility?
Language: Japanese
Type of talk: Literature review + a model
Abstract: This study examines how probability biases impact ego utility through belief distortions in Bayesian updating. Individuals frequently exhibit cognitive biases, such as the law of small numbers and the gambler’s fallacy. Our model reveals that biased individuals (Freddy) experience over(under)valued ego utility due to distorted probability assessments. Findings may have significant implications for financial and labor markets.
Speaker 2: HU Rongyu (doctoral student of Graduate School of Economics, Waseda University)
Title of talk: The Cost of Knowing: An Experiment on Ego Utility and Feedback to Self-performance
Language: English
Type of talk: Literature review + Experimental design
Abstract: This study experimentally investigates how ego utility influences information-seeking behavior. While previous research has shed light on models of ego-driven information avoidance, empirical evidence remains scarce. This scarcity arises because ego utility—which is generated from beliefs themselves and leads people to avoid information to protect their self-image—is difficult to isolate and measure using naturally occurring data alone. We employ a three-stage experiment, consisting of an IQ test, belief elicitation, and a feedback choice task, intend to provide evidence of how ego utility creates psychological frictions and drives information avoidance.
WINPEC 行動・実験経済学研究会は、早稲田大学現代政治経済研究所（WINPEC）の研究部会として、早稲田大学政治経済学術院教授 上條良夫によって、2025年2月に設立されました。
The WINPEC Behavioral and Experimental Economics Seminar (BEES) was established in February 2025 by Professor Yoshio Kamijo (Fuculty of Political Science and Economics, Waseda University) as a research subgroup within the Waseda Institute of Political Economy (WINPEC)

目的 🐝
近年、行動経済学・実験経済学に関する研究手法の発展は目覚ましいものがあります。
最新の研究成果および研究実践について共有することを通じて、
博士課程学生および若手研究者の研究レベルの向上を目指します。
In recent years, there has been remarkable development in research methods related to behavioral and experimental economics. Our aim is to enhance the research capabilities of PhD students and early-career researchers by sharing the latest research findings and practices.
和名をそのまま英訳したらBehavioral and Experimental Economics Seminar となり、略称を BEES とすることとしました。社会性昆虫として知られる Bee(s) 🐝 は、勤勉さと協業の象徴であり、まさに近年の大規模化する研究を実践する上で必要不可欠な要素です。その一方で、蜂は危険を伴う生物でもありそれゆえ警戒が必要です。そのような心構えは実験研究のみならずあらゆる種類の研究を実施する上で必要なマインドでもあります。このように、まったくの偶然ですが、Bee(s) は研究者に必要な資質をうまく象徴していると思えたので、これを研究会の略称およびシンボルとすることとしました。
The Japanese name translates directly to "Behavioral and Experimental Economics Seminar," and we have decided to use the abbreviation BEES. The bee 🐝, known as a social insect, symbolizes diligence and collaboration, which are essential elements for conducting large-scale research in recent years. On the other hand, bees are also creatures that can pose risks, requiring caution. This mindset is necessary not only for experimental research but for all types of research. Interestingly, by pure coincidence, bees represent the qualities that researchers need. Therefore, we have chosen this as the abbreviation and symbol for our research group.
