Gender Segregation in Small Firms
研究小企业间的性别隔离现象，发现男女很少在完全融合的企业工作，企业主的教育和性别显著影响员工性别构成，且企业间隔离可解释高达50%的年收入性别差距。
This paper studies interfirm gender segregation in a unique sample of small employers. We find that interfirm segregation is prevalent among small employers, as men and women rarely work in fully integrated firms. We also find that the education and sex of the business owner strongly influence the sex composition of a firm's workforce. Finally, we estimate that interfirm segregation can account for up to 50 percent of the gender gap in annual earnings.
