ABSTRACT
This chapter discusses the most important results of the individual income return approach. It deals with refinements and methodological aspects. The chapter looks at the productivity effects at various aggregation levels, and at the relationship between education and the development and diffusion of knowledge. Individuals who have passed the age of compulsory education have the choice between taking a job and taking further education. Part-time jobs are to be regarded as inactivity. Working part time means that the return to education is less. The chapter also looks at the financial gains resulting from particular education routes. Non-financial benefits may also differ per type of education, at least insofar as there is a direct relationship between type of education and occupation: given the same reward, one job will be considered more attractive than another. The effects of initial education paths measured in other studies are in fact partly attributable to in-service training.
