Faculty

After Shohei Yamamoto earned his PhD in Economics, Finance and Management from Universitat Pompeu Fabra (Barcelona, Spain), he became a specially appointed assistant professor at Hitotsubashi ICS. He currently leads the Hitotsubashi ICS Xlab, an experimental laboratory at Hitotsubashi ICS.

His work focuses on behavioral science, exploring both economic and psychological dimensions. His research is specifically interested in individual decision-making processes. He examines how individuals make choices and the circumstances in which they may make suboptimal decisions due to cognitive biases. Furthermore, he explores how specific interventions can mitigate such biases. His inquiries utilize a diverse array of methods, ranging from online and lab-based studies to field experiments.

Since 2021, he has been an active member of PolicyGarage, a non-profit organization engaged in consulting and knowledge dissemination with local governments using insights from behavioral science. In 2022, he was appointed as an advisor to the Mie Research Center for Local Autonomy. His expertise also includes providing insights on nudge theory to local governments through presentations in many cities, including Matsusaka, Tsu, and Nagano cities.
