  • Mathematical Economics Seminar: Experimental Design in Networks

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Speaker: Christopher Harshaw (c.harshaw@columbia.edu), Columbia University Title: Design-Based Minimax Theory for Network Experiments Abstract: Network experiments are used throughout the social and medical sciences to investigate causal effects under the presence of interference. While a large body of work has developed improved statistical procedures, the fundamental limits of statistical estimation in these settings is less well understood. […]

    Speaker: Karun Adusumilli, University of Pennsylvania, Title: Continuous Time Asymptotic Representations for Adaptive Experiments Abstract: This article develops a continuous-time asymptotic framework for analyzing adaptive experiments—settings in which data collection and treatment assignment evolve dynamically in response to incoming information. Akey challenge in analyzing fully adaptive experiments, where the assignment policy is updated after each […]
