According to recent literature, this paper highlights the relevance of spatial mobility as an explanatory factor of the individual risk of job-education mismatch. To investigate this causal link, we use individual information about daily home-to-work commuting time and choices to relocate in a different local area to get a job. Our model takes into account relevant local labour market features. We control for selective access to employment and test for endogeneity of spatial mobility. Results show a negative impact of commuting time on educational mismatch for upper-secondary graduates, as well as a negative impact of migration/migration distance for university graduates.
