Notes: OLS estimates are from separate regressions of the educational outcome on a constant and veteran status for each PGS category. Reduced form estimates are from separate regressions of the educational outcome on a constant and draft eligibility for each PGS category. The difference between estimates is calculated using a post linear combination of the estimation results that accounts for the between-model covariance of parameter estimates. Robust standard errors are in parentheses. No control variables.
