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.
