Choi, Hwang and Denzau (2021) found that social norm was not effective for encouraging energy conservation in Korea because the residents did not share mentally the social consensus of "reducing energy use when knowing that mine exceeded similar others". Based on the shared mental models (Denzau and North, 1994), our lab is developing theoretical framework and designing a way to build up social norm in community for helping the community members taking the norm as a significant factor of their energy consumption and conservation.

Denzau and North's Shared Mental Models for Social Norm and Energy Conservation in Residential Sector
Agent-based Model Designing and Developing for the Korean Electricity Market-Economy System
How do electricity consumers respond to a variety of deregulation policies in Korea? As the risk and uncertainty tend to be rising longer in the global energy market, deregulation and restructuring inquiries for energy market efficiency are strongly encouraged in Korea which heavily depends on imported energy. Especially, among energy industries, the electricity industry has been taking persistent attention from policy makers as a restructuring target in Korea and to be discussed whether the restructuring could be successful for the social welfare. Although many agent-based models for electricity markets have been developed by renowned institutions, such as, Argonne National Lab, Iowa State Univ., Imperial College, etc, but there is a still debate about "Which model should be employed to measure benefits and harms of the restructuring policies on the market and entire economy?" More specifically, a critical question is to find a model to be best fitted for Korean electricity consumer's heterogeneous characteristics which has not been considered yet in existing models and research. With substantial supports by Korean government institutions, EPRC staff attempts to design and develop the most appropriate "agent-based model" for explaining Korean electricity market as well as other economic sectors.
Reactions to Risk and Uncertainty: Private vs. Public Corporations
Choi, Salam, and Kim (2020) found the foreign currency derivatives use has different effect on firm's value by type of firms in Bangladesh, implying that corporation type is an important condition for analyzing corporate risk management because profit structure of firm is different by type of firm. From the two largest databases containing micro-level information on Korean firms, KISVALE and KISLINE, we explore how private and public corporations differently react to risk and uncertainty during the past two decades including the COVID pandemic.
Experimental Public Choice with Korean Cases and Eye-tracking Experiment
We conduct experiment on key public choice issues, such as, public goods, voter turnout and participation games, rent seeking and lobbying, and spatial voting. Our experiment results suggest the power of eye-tracking experiment as well as unique evidence from Korean samples
