AME refers to the average marginal effects on the survival rate in % from a 1% change in the apprenticeship wage in relation to low skilled workers wage (\(W/W^{(l)}\)) and the natural logarithm of daily skilled worker wage (\(ln \text { }W^{(m)}\)), respectively. Estimates account for shared frailties in 35 occupation clusters. SE denotes occupation cluster robust standard errors. N = 41,921 observations, n = 94,223 apprenticeships, f = 19,697 incidences of non-completion. For estimated hazard ratios, see full results in Appendix: Table 9
