Notes: (1) dependent variable equals one if usually works 30+ hours per week, and equals zero otherwise; (2) in column one, sample is restricted to licensed practical/vocational nurses who reported being employed; (3) all regressions include a constant; and (4) standard errors are estimated using the "robust" option in Stata.
