When productivity is costly to measure, employers and employees will e
stablish trust relationships to their mutual benefit. Our thesis is th
at in such relationships educational credentials are important to get
entry to the job. Dutch Labor Force Sample Surveys from 1981 and 1985
are used to estimate the relationship between educational credentials
and job level within different firm sizes and different sectors of the
economy. We find a stronger relationship within large firms than with
in small firms and within so called 'high trust' sectors than in 'low
trust' sectors. Analyzing the differences between the two periods adds
support to our thesis.
