The Impact of Horizontal and Vertical Educational Mismatches on Wages

Summary/Abstract: The aim of the article was to assess the impact of horizontal and vertical educational mismatches on wages of various school graduates in Poland. (Horizontal mismatch is understood as formally the same educational level as required for the given job while vertical mismatch denotes another educational level than required for the given job, meaning undereducation or overeducation). The data source was a large set of survey data collected in 2014 under a research project „Social and economic determinants of choices made by persons at the age between 19 and 30 years concerning studying”, conducted in the Institute of Education Research. In the empirical research, a remuneration model was used based on Mincer’s equation, with Heckman’s correction because of non-random sample of employed. The results indicate that there exists a negative wage premium due to horizontal mismatch, which is the larger, the larger the mismatch is. In the case of vertical mismatch, there is a positive wage premium due to undereducation and a negative wage premium due to overeducation.
