人们对大型雇主的作用以及在当地劳动力市场上拥有巨大影响力的雇主的兴趣激增。我们使用职业就业统计（OES）的详细微观数据来表明这些是不一样的。我们构建了大型企业就业和雇主劳动力市场力量的衡量标准，遵循这一不断增长的文献中发现的多种方法，从2005年到2017年，几乎所有美国工人，所有行业，所有职业和所有地理区域。我们发现，在一个地理区域的巨型企业的就业程度和该地区的跨职业或跨行业的雇主集中度的平均水平之间没有相关性，但在地理区域的跨职业的雇主集中度和跨行业的雇主集中度的平均水平之间有极高的相关性。我们发现，雇主的集中度一般随着地理区域或职业的就业规模而下降，但地区或职业的就业规模与超大型企业的就业份额之间没有这种关系。此外，大型企业的就业趋势与高度集中的劳动力市场的趋势截然不同。我们还表明，相对较少的雇员的巨型公司雇用当地寡头，和相对较少的雇员的本地寡头受雇于巨型公司。那些受雇于巨型公司和寡头垄断者的人在公共部门的比例不成比例。免责声明：本文中的任何观点和结论都是作者的观点和结论，并不一定反映美国劳工统计局的观点或政策。2019年7月12日的初步和不完整版本
There has been an explosion of interest in the role of very large employers and in employers with monopsony power in local labor markets. We use the detailed microdata of the Occupational Employment Statistics (OES) to show that these are not the same. We construct measures of megafirm employment and employer labor market power, following multiple approaches found in this growing literature, for nearly all workers in the United States, in all sectors, all occupations, and all geographic areas, from 2005 to 2017. We show there is no correlation between the extent of employment in megafirms for a geographic area and that area’s average level of employer concentration across occupations or across industries, but extremely high correlation between average levels of employer concentration across occupations and employer concentration across industries for geographic areas. We show that employer concentration is generally falling with employment size in geographic areas or occupations, but there is no such relationship between employment size in areas or occupations and the share of employment in megafirms. Furthermore, trends in employment in megafirms are very different from trends in highly concentrated labor markets. We also show that relatively few of the employees of megafirms are employed by local oligopsonists, and relatively few of the employees of local oligopsonists are employed in megafirms. Those employed by both megafirms and oligopsonists are disproportionately found in the public sector.
