Occupational mismatch has been a hot topic in the economics literature in recent decades; however, no consensus has been reached on how to conceptualise and measure this phenomenon. We explore the unique opportunity offered by the PIAAC survey to measure occupational mismatch at the individual level based on both education-(overeducation) and skill-based (overskilling) variables by using both objective and subjective measures. For this purpose, we use data on 17 European countries and compute up to 20 different indicators of occupational mismatch. We find that the conceptualisation and measurement of occupational mismatch are indeed important and that education and skill mismatch do not measure the same phenomenon. In fact, only a small percentage of mismatched individuals are mismatched with respect to both education and skill, whereas the majority are mismatched with respect to either education or skill only. At the country level, we find a negative correlation between the incidence of education and skill mismatch, which has important implications for policies aiming to address this labour market inefficiency.

The potential benefits of increased international experience abound, ranging from enriching cultural understanding to an improvement of language skills and intercultural competence. At the same time, empirical evidence is mixed, particularly with regards to how well international experience translates into individual returns on the labour market. This article examines the association between studying abroad and early labour market outcomes in a comparative perspective aiming to shed light on why labour market returns differ across countries. We expect labour market returns to vary with specific country characteristics such as demand for international experience and competition among graduates at labour market entry. In our empirical analyses, we use data from 13 European countries that provide information on graduates’ early labour market outcomes. We find a large variation in the impact of studying abroad on both wages and attaining a higher service class position. Generally, the labour market returns to international experience are larger in countries in Eastern and Southern Europe with poorer university quality, higher graduate unemployment, and fewer students abroad.

Empirical evidence suggests that educational attainment nurtures people's social outcomes and promotes active participation in society and stability. However, it is unclear to what extent other types of human capital also correlate with social outcomes. Hence, we explored the opportunity offered by the PIAAC survey through its provision of information on educational attainment, observed individual key skills proficiency, and participation in adult education and training (adult lifelong learning). We therefore studied the association between these human capital variables and social outcomes, and more specifically interpersonal trust and participation in volunteering activities. Results revealed that these social outcomes were affected not only by the formal qualification obtained, determined by the education variable, but also throughout the life-cycle. Indeed, education and training when undertaken during adult life have a significant impact, especially on volunteering. The fact that the skill proficiency also plays a significant role is extremely relevant, as skills are more likely to change over the life-cycle, either in a positive or negative way. Whilst the formal education received is constant after exiting the educational system, skills reflect competences more accurately: first, because those with the same level of education may have different skill levels because of differences in the quality of education or ability; second, because skills can vary over time. For example, they may increase with work experience or informal education, or decrease as a result of depreciation and ageing. These findings suggest that social outcomes are prone to be affected by many factors other than formal education, suggesting that policy makers can implement recommendations even after formal education has been completed.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

This paper investigates the effect that participation in massive open online courses (MOOCs) ecosystem can have on workers' labour market outcomes, mainly employment retaining. We use primary data collected between 2015 and 2017 and obtained from two surveys (pre-course and follow-up questionnaires) sent to participants in six MOOCs. The treatment group is composed of individuals participating in MOOCs in 2015 and the control group is composed of individuals who enrolled in MOOCs for the first time in 2017. Using a differences-in-differences approach, we find that participation in MOOCs can improve workers’ employment retaining but not their wages. The positive effect on employment retaining is homogeneous in different geographical and economic areas and tends to be higher for individuals who have participated in more MOOCs in the past.
