Wage Inequality and Firm Growth
基于英国企业数据，发现企业内部工资不平等随企业规模扩大而增加，且随时间推移而加剧；跨国数据显示国家层面工资不平等与最大企业增长正相关。
We discuss firm-level evidence based on UK data showing that within-firm pay inequality--wage differentials between top- and bottom-level jobs--increases with firm size. Moreover, within-firm pay inequality rises as firms grow larger over time. Lastly, using wage data from 15 developed countries, we document a positive association between aggregate wage inequality at the country level and growth by the largest firms in the country. We conclude that part of what may be perceived as a global trend toward more wage inequality may be driven by an increase in the size of the largest firms in the economy.
