  1. Driscoll-Kraay standard errors in parentheses. Column OLS 4 includes yearly time and occupational category interaction effects (reference year is 2000, reference category is ‘[01] AGR Agrarian and not assignable occupations’), all dummy variables are effect coded, compare ‘Effect coding’ in the Appendix. Control variables are the share of female workers, the shares of workers at different skill levels (‘vocational training’ and ‘academic degree,’ reference group is ‘without vocational training’) in each NUTS3 region and occupation, and the average age by the population by NUTS3 regions. The estimated coefficients are provided on request.
