• Identifying Wisdom (of the Crowd): A Regression Approach

    Journal of Political Economy: Microeconomics, Accepted

    Blackwell experiments can be determined via a regression procedure. Priors solve an eigenvector equation derived from this procedure.

    The findings are relevant to the crowd wisdom problem, and have implications for the geometric structure of information.

  • Iterative Weak Learnability and Multiclass AdaBoost

    (with In-Koo Cho and Cheng Ding)

    Proc. of the 30th ACM SIGKDD Conference on Knowledge Discovery and Data Mining, 2024, 466-477

    We propose a procedure for multi-label classification problems based on iteratively eliminating worst-performing labels.

    We identify desireable theoretical properties of our procedure and illustrate its practical performance.

  • False Positives and Transparency

    American Economic Journal: Microeconomics, 2022, 14(2): 478-505.

    Lack of transparency over research methods can induce bias. But the incentive to de-bias may lead to more informative experiments.

    The model introduced is one of costly communication with partial (sender) commitment.

     

     

  • Informational Robustness in Intertemporal Pricing

    (with Xiaosheng Mu)

    Review of Economic Studies, 2021, 88(3): 1224-1252.

    Constant price paths deliver the optimal profit guarantee when a seller does not know how buyers learn about a product.

    Formally, this paper introduces an informationally robust approach into the dynamic pricing literature.
