Notes: Column two displays the estimated ATE after PSM with naturalisation as treatment. Results have been obtained by STATA procedure psmatch2 by Leuven and Sianesi (2013) (matching algorithm: Epanechnikov kernel with bandwidth 0.06, matching on the odds ratio of the propensity score). Standard errors in parentheses are bootstrapped with 200 replications. Furthermore, coefficients of LPM (column one) are shown. The naturalisation coefficient of the LPM refers to the naturalisation status in the previous year. Reported standard errors in parentheses are robust and clustered by individual. ** denotes statistical significance at the 5 % level. The sample is restricted to first-generation immigrants aged 25 to 55. The outcome variable is “participation in on-the-job training”
