题 目：Do judges weight prior information when forming evaluations? Evidence from figure skating
报告人：Pascal Courty
主持人：龚冰琳
内容简介：
In a two-stage evaluation setting, judges can use information from the first stage to form priors about the second-stage performance. In figure skating, different institutional rules determine how skaters are ordered in the second stage, and this reveals coarse or fine signals about the skater’s first-stage performance. We use a regression discontinuity design to identify whether judges update a prior based on past scores using their private signal of performance. We show that judges systematically use prior scores, despite explicit instructions not to. The use of priors—especially coarse ones—distorts the information aggregation process and produces inefficient and biased rankings.
