Winner's Curse Undermines Data-Driven Decisions in Management Science Research

By PulseAugur Editorial · [1 sources] ·

A new paper published on arXiv highlights a significant flaw in data-driven decision-making methodologies, particularly within the field of Management Science. The research, led by Bryce McLaughlin, demonstrates that a phenomenon known as the "winner's curse" leads to overly optimistic and often false promises of policy benefits. This occurs when models are used to estimate outcomes from historical data, a technique employed by nearly all papers in Management Science over the past decade. The study's simulations, including a synthetic refugee matching problem, showed that these methods can report substantial gains even when no actual improvement exists, undermining the reliability of such data-driven evaluations.

    Winner's Curse Drives False Promises in Data-Driven Decisions

    arXiv:2602.08892v2 Announce Type: replace Abstract: A major challenge in data-driven decision-making is accurate policy evaluation---i.e., guaranteeing that a learned decision-making policy achieves the promised benefits. A popular strategy is model-based policy evaluation, which…
