About the Lab

Professor Duk-gyu Kim's research lab specializes in experimental and behavioral economics, with a focus on strategic decision-making in bargaining, competition, and institutional design. The lab investigates how individuals behave in strategic environments involving rent-seeking, information asymmetry, and costly competition, often using controlled laboratory experiments. Recent work also explores the impact of emerging technologies—such as large language models like ChatGPT—on human performance and decision accuracy. Additionally, the lab examines institutional mechanisms for regulating financial innovation, particularly in peer-to-peer (P2P) lending and crowdfunding platforms, emphasizing regulatory design and consumer protection.

Multilateral bargaining with proposer selection contest
Duk Gyoo Kim, Sang‐Hyun Kim
SJR Q2Canadian Journal of Economics/Revue canadienne d économique

Abstract This study investigates the competition to be selected as the proposer in a subsequent multilateral bargaining game experimentally. The experimental environment varies in two dimensions: reservation payoffs (homogeneous or heterogeneous) and information on the extent of each subject's investment in the competition (public or private). The proposer's share was significantly lower than what theory predicts, and with taking into account the proposer's partial rent extraction, subjects over

대출형 부동산 크라우드 펀딩의 법적 문제 및 개선방안-P2P대출 플랫폼의 중개업자를 중심으로-
김덕규, 임춘성
금융법연구

본 연구의 중심은 크라우드 펀딩 유형 중, 부동산시장의 다변화로 중개업뿐 아니라 저금리시대에 고수익 기대 및 중금리 대출 제공 등 새로운 금융상품으로 각광받는 대출형 부동산 크라우드 펀딩(P2P대출)의 현상과 문제점을 진단하고 개선방안을 제시하는 데 있다. 크라우드 펀딩의 장점을 크게 퇴색시키지 않으며 이러한 위험을 효과적으로 차단할 수 있는 적절한 규제장치는 무엇이고 그 수준은 어느 정도인가에 있다고 할 것이다. 따라서 법과 제도적 보완책으로 첫째, 부동산 크라우드 펀딩 P2P대출을 미국에서와 같이 “증권”으로 보아 P2P대출 중개업자를 자본시장법상의 규제대상으로 하고 금융투자업자인 투자중개업자로 등록 및 사업자의 신용정보를 관리하고 둘째, 부동산 크라우드 펀딩 플랫폼 자금공급자에 대한 다양한 정보공시 의무 및 이자율 규제, 자금공급자에 대한 내부운영 규제 등이 요구된다. 마지막으로 차입자의 개인신용정보 보호를 위해 P2P대출 중개업자 등이 신용정보회사 등에게 채권회수위임을 할 예

From helping hand to stumbling block: the ChatGPT paradox in competency experiment
Duk Gyoo Kim, Ahram Moon
SJR Q3Applied Economics Letters

We ran a controlled laboratory experiment to examine whether ChatGPT’s aid can increase the participants’ performance in three different – reading and writing, mathematical problem-solving, and computational thinking – tasks. We find that the maths score significantly decreases with ChatGPT’s assistance. This result is mainly because the low-ability subjects couldn’t discern the hallucinated answers with the correct ones, and it contests the general idea that ChatGPT can complement the workers w
