中文摘要
摘要 企业被允许使用市场薪资的汇总数据来设定薪酬，这一做法被称为薪资基准比较。利用全国工资单数据，我们研究了获得一种工具访问权限的企业，该工具可揭示每个职位名称的市场基准。采用双重差分（DID）设计，我们发现基准信息使薪资离散度降低了25%。因此，薪资离散度必然部分源于对其他企业所提供薪资的汇总不确定性。我们的模型形式化说明了，即便是在相同劳动者的竞争性劳动力市场中，只要存在这种不确定性，薪资离散度也可能产生，并讨论了这一发现对当前政策辩论的启示。
Abstract
Abstract Firms are allowed to use aggregate data on market salaries to set pay, a practice known as salary benchmarking. Using national payroll data, we study firms that gain access to a tool that reveals market benchmarks for each job title. Using a difference-in-differences design, we find that the benchmark information reduces salary dispersion by 25%. Thus, salary dispersion must stem partly from aggregate uncertainty about the salaries offered by other firms. Our model formalizes how salary dispersion can arise even in competitive labour markets for identical workers when such uncertainty exists, and we discuss implications for an ongoing policy debate.
