I am an assistant professor of economics at KAIST College of Business. I am interested in experimental economics, political economy, and social networks. I received my B.S. in mathematics and B.A. in economics from Yonsei University in South Korea. In 2016, I received my Ph.D. in the social sciences (Equiv. Ph.D. in economics) from the California Institute of Technology, under the advisement of Professor Leeat Yariv. Subsequently, I was hired as an assistant professor of economics at Kyung Hee University in South Korea, and I have been at KAIST College of Business since 2018. [Download my CV here] [한글이력서 다운로드]

My research interests explore two themes: (i) providing better explanations for individuals’ and firms’ strategic behaviors in various contexts and (ii) contributing to the achievement of UN Sustainable Development Goals (UNSDGs). All of the research papers are publicly available on my webpage: https://sites.google.com/site/euncheolshin00/. [Click here to visite]

The first theme can be broadly grouped into two categories. The first category considers (i) important aspects of networks in the context of network formation and agents' behavior in different contexts and (ii) how economic agents optimize their behaviors for a given network structure, where one's behavior affects other agents' incentives heterogeneously. The second category examines how institutional factors such as decision rules (e.g., type of electoral voting system and frequency of national elections) affect individual voting decisions and shape electoral outcomes. In addition to developing theoretical models, I have conducted economic (lab and field) experiments to understand how institutional instruments (e.g., teaching methods) influence individuals' economic choices and social preferences (e.g., altruism, trust, and reciprocity).

The second theme is particularly related to quality education (Action 4), affordable and clean energy (Action 7), sustainable cities and communities (Action 11), and climate action (Action 13), jointly. As the advent of artificial intelligence (AI) presents an effective method for quality education, I am studying its impact on students' performance and their satisfaction in schools in experimental settings. This approach is based on the fact that AI technologies have proven their outstanding performance regarding tasks that were viewed as too complex to be executed before, such as mass customization and recommendation systems generally. Thus, I am trying to identify their impact on education and explore the possibilities of expanding their use in the public education system. Regarding the other two actions, I have examined the impact of personalized nudges by evaluating their effects on residential consumers' energy-saving behavior. Specifically, I have explored how the impact of nudges varies according to types of consumer misperception in relation to electricity usage. Instead of short-term saving behavior, my research emphasizes the long-term effects of changing consumers' misperceptions.
