Educational mismatch in Europe at the turn of the century: Measurement, intensity and evolution

The purpose of this paper is to present the stylised facts of over-education among European graduates over time (1998–2013), paying special attention to the measurement issues.

The authors use two different sources, the Programme for the International Assessment of Adult Competencies 2012, and the European Union Labour Force Survey 1998–2013, with two different aims. The authors employ the first one to make a detailed analysis of the different forms of measuring over-education and its implications in terms of the result obtained. The analysis of the second one responds to studying the evolution and characteristics of over-education in Europe.

In the first place, the paper provides evidence of the high level of sensitivity of the level of measured over-education to the type of methodology used. Such difference is even higher when the authors focus on skills vs educational mismatch. The work also shows how with all their shortcomings, the measures of over-education used in the analysis point to the existence of convergence in over-education levels among the European countries of the sample (only interrupted by the crisis), in a context of reduction of over-education rates in many countries.

Researchers should be particularly careful when estimating over-education, because of the strong implications in terms of the so different results obtained when choosing between competing methods.

The analysis abounds in the implications of the use of different methodologies of estimating over-education in terms of both size and ranking among European countries. The production of long-run and updated estimates of over-education for a large sample of countries is done using a homogenous database and different estimation methods.
