In this report we estimate the impact on participation in adult education and training (E&T) of changes in the employment structure resulting from technological developments. We look at the influence on participation of employment dynamics in two areas: on the one hand, complex non-routine Information and Communications Technology (ICT) occupations; and on the other, non-complex, non-routine Personal Service and Personal Care (PSPC) occupations. Our findings indicate a positive and significant relationship between levels of employment and participation in adult E&T. In particular, we estimate that a 100 percent increase in the level of employment of ICT professionals is associated with a 7.2 percent increase in participation in job-related courses. A 100 percent increase in the level of employment of PSPC workers is associated with a 4.5 percent increase in participation in such courses. Our findings further indicate that the effects of employment dynamics on participation in job-related courses is significantly mediated by firms’ effective demand for skill; this applies both among ICT professionals, and (though to a lesser extent) among PSPC workers.
