Associate Professor of Economics

Lingnan College, Sun Yat-sen University
Microeconomics and Digital Economy Research Division · Guangzhou, China

I am an applied microeconomic theorist working on social and economic networks, behavioral game theory, and the impact of AI on the economy. My research uses formal models, evolutionary dynamics, and experiments to study strategic interaction, cooperation, social norms, and network design. I am also interested in how AI technologies reshape decision-making and organizational forms. I received my PhD in Economics from the University of Nottingham in 2018.

    Indignation and the Evolution of Cooperation Norms

    Xueheng Li. Games and Economic Behavior, 155, 228–249.

    This paper models indignation as a belief-dependent emotion and applies stochastic stability to show that cooperation norms can persist and that mobility can expand cooperative communities.

    Decomposability and the Social Comparison Trap

    Zhiwei Cui, Xueheng Li, and Boyu Zhang. Journal of Mathematical Economics, 120, 103169.

    This paper identifies decomposable games as a tractable class for social-comparison preferences and shows that comparison motives can generate outcomes worse than those under material-payoff maximization.

Working papers

  1. The Structure and Gender Differences in Overconfidence

    Xueheng Li, Jiayi Liang, Xiaomeng Zhang, Shan Jin, and Wei Wang.

    This paper separates overconfidence into distinct components and examines how each contributes to observed gender differences in confidence.

  2. Influencer Networks

    Yanlin Chen, Xueheng Li, and Tianle Song.

    This paper models content provision when followers raise its marginal returns and characterizes the nested, tiered structure of equilibrium influencer networks.

Work in progress

  1. Moral Narratives Need Norms

    Despoina Alempaki, Valeria Burdea, and Xueheng Li.

    Six preregistered experiments with more than 9,000 participants show that pro-honesty narratives reduce lying when anti-lying norms are strong, revealing a complementarity between narratives and norms.

  2. Imitation and Single-Deviant Comparison Graphs

    Zhiwei Cui and Xueheng Li.

    This paper introduces the single-deviant comparison graph to characterize stochastically stable imitation outcomes and shows how wasteful social-comparison-like outcomes can arise without preferences for relative standing.
