BW, black women; BM, black men; WW, white women; WM, white men.
empstat codes: 1 = discouraged 2 = searching 3 = employed. Omitted: not economically active.
FE (B)—Fixed Effects Regression on Black subpopulation; RE (B)—Random Effects Regression on Black subpopulation.
Estimates in columns 1–5 weighted, using calibrated weights. It doesn’t make sense to weight RE regressions.
