Notes: Estimations are based on the respondents who were employed and not enrolled at any postsecondary institutions in 2009 and 2012, respectively. Control variables in the outcome function are the same as in the full model. Propensity scores are estimated from the preferred logit model. OLS = ordinary least squares; PSW = propensity score weighting; BA = bachelor's degree.

**p < 0.05; ***p < 0.01.
