  1. aNumber of covariates for which ASDM>3.
  2. bNumber of covariates for which a t-test for equal means yield a p-value < 0.05.
  3. cTotal number of covariates.
  4. dThe counterfactual case is changed from “non-participation” to “never-participation”.
  5. eThe timing of disability coding is ignored.
  6. fThe disability coding is ignored altogether.
  7. gJobseekers who were not full-time unemployed at the time of registration at the PES are dropped.
  8. hBoth participation and non-participation is conditional on being employed in the month of November.
  9. iLabour market histories earlier than the year immediately preceding the year of (potential) program participation are not included in the estimation of the propensity scores
