摘要翻译：
我们使用多臂强盗模型分析了雇佣市场中的统计歧视。短视的公司面对具有不同可观察特征的工人。工人的技能与特征之间的关联事先是未知的；因此，企业需要学习它。自由放任导致长期低估：少数族裔工人很少被雇用，因此，对他们的低估往往持续存在。即使是轻微的人口比例失衡，也经常导致长期的低估。我们提出了两个政策解决方案：一个新的补贴规则（混合机制）和鲁尼规则。我们的结果表明，临时平权行动有效地缓解了由于数据不足而造成的歧视。

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, underestimation towards them tends to persist. Even a slight population-ratio imbalance frequently produces 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 mitigate discrimination caused by insufficient data.
