论统计歧视作为社会学习的失败:一种多臂老虎机方法

On Statistical Discrimination as a Failure of Social Learning: A Multi-Armed Bandit Approach

Junpei Komiyama, Shunya Noda

AI总结:

本文用多臂老虎机模型刻画招聘中的社会学习,说明自由放任会使少数群体因数据不足而被持续低估,并提出混合补贴机制与 Rooney Rule,证明临时平权行动可有效缓解此类统计歧视。

摘要:

我们使用多臂老虎机模型分析招聘市场中的统计歧视。短视企业面对具有异质性可观察特征的工人。工人技能与特征之间的关联在事前未知;因此,企业需要对其进行学习。自由放任会导致永久性低估:少数族裔工人很少被雇用,因此这种低估往往会持续存在。即使人口比例中微小的不平衡,也经常导致永久性低估。我们提出两种政策解决方案:一种新颖的补贴规则(混合机制)和 Rooney Rule。我们的结果表明,临时性平权行动能有效缓解源于数据不足的歧视。

英文摘要:

We analyze statistical discrimination in hiring markets using a multi-armed bandit model. Myopic firms face workers arriving with heterogeneous observable characteristics. The association between the worker's skill and characteristics is unknown ex ante; thus, firms need to learn it. Laissez-faire causes perpetual underestimation: minority workers are rarely hired, and therefore, the underestimation tends to persist. Even a marginal imbalance in the population ratio frequently results in perpetual underestimation. We propose two policy solutions: a novel subsidy rule (the hybrid mechanism) and the Rooney Rule. Our results indicate that temporary affirmative actions effectively alleviate discrimination stemming from insufficient data.
