The Dynamics of Discrimination: Theory and Evidence
构建歧视动态模型，并通过在线平台现场实验发现：无历史评价时女性受歧视，但连续好评后歧视反转，表明歧视源于偏见信念。
We model the dynamics of discrimination and show how its evolution can identify the underlying source. We test these theoretical predictions in a field experiment on a large online platform where users post content that is evaluated by other users on the platform. We assign posts to accounts that exogenously vary by gender and evaluation histories. With no prior evaluations, women face significant discrimination. However, following a sequence of positive evaluations, the direction of discrimination reverses: women’s posts are favored over men’s. Interpreting these results through the lens of our model, this dynamic reversal implies discrimination driven by biased beliefs.
