Note.—95% confidence intervals are in parentheses. Data come from the CPS-MORG files, 1984–2002. Models are weighted with the appropriate CPS weights. Coefficients from suppressed control variables are available on request. Estimates are restricted to private-sector workers ages 16–64 with positive earnings and hours worked.
