This paper provides more insight into the assumption of human capital theory that the productivity of job-related training is driven by the improvement of workers’ skills. We analyze the extent to which training and informal learning on the job are related to employee skill development and consider the heterogeneity of this relationship with respect to workers’ skill mismatch at job entry. Using data from the 2014 European Skills and Jobs Survey, we find – as assumed by human capital theory – that employees who participated in training or informal learning show greater improvement of their skills than those who did not. The contribution of informal learning to employee skill development appears to be larger than that of training participation. Nevertheless, both forms of learning are shown to be complementary. This complementarity between training and informal learning is related to a significant additional improvement of workers’ skills. The skill development of workers who were initially underskilled for their job seems to benefit the most from both training and informal learning, whereas the skill development of those who were initially overskilled benefits the least. Work-related learning investments in the latter group seem to be more functional in offsetting skill depreciation than in fostering skill accumulation.

This paper contributes to the literature on overeducation by empirically investigating the wage penalty of job–education mismatch among PhD holders who completed their studies in Italy; a country where the number of new doctoral recipients has dramatically increased over recent years while personnel employed in R&D activities is still below the European average. We use cross-sectional micro-data collected in 2009 and rely on different definitions of education–job mismatch such as, overeducation, overskilling, and dissatisfaction with the use of skills. We find that overeducation and skills dissatisfaction are associated with significantly lower wages but there is no wage penalty from overskilling. Furthermore, those who simultaneously report overeducation and skills dissatisfaction experience a particularly high wage penalty.

At a time when industrial expense is under great pressure, particularly training budgets, it is of great importance that training is carefully focused, to ensure that organizations obtain the maximum benefit. The widely accepted procedures for evaluation described by Donald Kirkpatrick almost without exception have been applied only at level 1 (Student Reaction forms). Many researchers have questioned the value of this part‐application of an evaluation strategy. This new system of training effectiveness evaluation not only forms the basis of individual analysis, but also allows group deficiencies to be explored over time. The method based on self‐perceived skill gap measurement allows the monitoring of skills management at individual departmental and organizational levels and gives management, for the first time, a control measure to which skill management budgets (of which training is a part) can be compared.

We investigate the relationship between job complexity and skill development of adult workers in Europe using the Cedefop European Skills and Jobs Survey. ¹ The results suggest that challenging workplaces in which jobs are designed to include complex tasks that place high demands on workers’ skills also stimulate skill development. Increasing the degree of job complexity has positive and robust effects on the degree of skill development. Skill development is also positively linked to job tenure. The analysis stresses the importance of on-the-job learning and contextual workplace characteristics for adult workers’ skill development.

This study aims to investigate the extent to which overeducation imposes wage effects on university graduates, taking into account the individual heterogeneity due to skills and innate ability.

Using Graduates Occupation and Mobility Survey (GOMS) 2019 and Korea Dictionary of Occupations (KDOT) 2019, the overeducated and adequately educated graduates are differentiated by the job analysis (JA) measure. To unveil the masked results, the unconditional quantile regression (UQR) accompanying skills and field of study mismatches is adopted to explore the wage effects of overeducation across the overall wage distribution.

Empirical evidence shows that the incidence of overeducation is high; however, overeducated graduates only suffer a 6.5% wage loss relative to their adequately matched peers. The findings indicate that regardless of being derived from either overskilled or field of study mismatch, genuine overeducation impose a higher wage penalty at all percentiles relative to the apparent overeducation. Meanwhile, high-ability men suffer lower-wage penalties than their low-ability peers, whereas the inverted “U” pattern is exhibited for women. The theoretical hypotheses differ depending on the estimated results by gender.

Each measure of educational mismatch has been criticized for its insurmountable shortcoming. The recent graduates are likely to overstate the job requires of skills.

This paper contributes to the insufficient evidence on the multiple aspects of wage effects of overeducation by providing new and rigorous examinations and by focusing on the country experiencing rapid economic growth, industrial upgrading and educational expansion.

The purpose of this paper is to propose an improved concept of educational mismatch that combines a statistical measure of over- and undereducation with the worker’s self-assessment of skill utilization. The novelty of this measurement approach consists in identifying the vertical and horizontal nature of skills mismatch, that is, a mismatch in which skills are either over/underutilized or not utilized.

Cross-sectional data from the Swiss Household Panel survey for the years 1999 and 2004 are used to determine the true extent of educational mismatch among workers. Moroever, different versions of the Duncan and Hoffman wage equation are estimated depending on whether basic or alternative measures of educational mismatch are included.

The empirical analyses provide the following results: first, at least two-third of the statistically defined overeducated workers perceive their skills as adequate for the job they hold and are then apparently overeducated; second, overeducated workers whose skills are not related to the job do not receive any payoff to years of surplus education; and third, apparently overeducated workers have similar wage returns compared to others with the same schooling level but who are statistically matched. All in all, these findings confirm that most of those overeducated according to the statistical measure have unobserved skills that allow them to work in a job for which they are well-matched.

The paper indicates the need to consider both vertical and horizontal skill mismatches when measuring educational mismatch in the labour market. In that way, it is possible to account for worker heterogeneity in skills whose omission may generate biased estimates of the incidence and wage effects of over- and undereducation.

The explicit assumption in most literature on educational and skill mismatches is that these mismatches are inherently costly for workers. However, the results in the literature on the effects of underqualification or underskilling on wages and job satisfaction only partly support this hypothesis. Rather than assuming that both skill surpluses and skill deficits are inherently costly for workers, we interpret these mixed findings by taking a learning perspective on skill mismatches. Following the theory of Vygotski on the so-called “zone of proximal development,” we expect that workers who start their job with a small skill deficit, show more skill growth than workers who start in a matching job or workers with a more severe skill deficit. We test this hypothesis using the Cedefop European skills and jobs survey (ESJS) and the results confirm these expectations. Workers learn more from job tasks that are more demanding than if they would work in a job that perfectly matches their initial skill level and this skill growth is largest for those who start with a small skill deficit. The learning opportunities are worst when workers start in a job for which they have a skill surplus. This is reflected in the type of learning activities that workers take up. Workers with a small skill deficit are more often engaged in informal learning activities. Finally, workers who started with a small skill deficit are no less satisfied with their job than workers who started in a well-matched job. We conclude that a skill match is good for workers, but a small skill deficit is even better. This puts some responsibility on employers to keep job tasks and responsibilities at a challenging level for their employees.

This paper uses data from the Cedefop European Skills and Jobs survey (ESJS) (Cedefop, 2014, ESJS microdata are Cedefop copyright and are reproduced with the permission of Cedefop. Further information is available at Cedefop, 2015), a new international dataset on skill mismatch of adult workers in 28 EU countries, to decompose the wage penalty of overeducated workers. The ESJ survey allows for integration of a rich set of variables in the estimation of the effect of overeducation on earnings, such as individuals’ job search motives and the skill needs of their jobs. Oaxaca decomposition techniques are employed to uncover the extent to which the earnings penalties of overeducated workers can be attributed to either (i) individual human capital attributes, (ii) job characteristics, (iii) information asymmetries, (iv) compensating job attributes, or (iv) assignment to jobs with different skill needs. Differences in human capital and job-skill requirements are important factors in explaining the wage premium. It is found that asymmetry of information accounts for a significant part of the overeducation wage penalty of tertiary education graduates, whereas job characteristics and the low skill content of their jobs can explain most of the wage gap for medium-qualified employees. Little evidence is found in favor of equilibrium theories of compensating wage differentials and career mobility. Accepting that much remains to be learned with regards to the drivers of overeducation, this paper provides evidence in support of the need for customized policy responses to tackle overeducation.
