Over-education among italian Ph.D. graduates. Does the crisis make a difference?

The paper examines the determinants of over-education among Italian Ph.D graduates drawn from the four cohorts 2004, 2006, 2008, 2010 surveyed by the Italian National Institute of Statistics (ISTAT). We attempt to disentangle the differentiated effects of the economic crisis and the university reform that recently hit the Italian labour market. We examine over-education through the definitions of over-skilling, over-qualification and a combination of the two. The results show that socio-demographic variables do not exert a relevant influence on over-education. Conversely, job attributes such as working in academia or carrying out R&D activities reduce the likelihood of incurring into over-education. Instead, accessing the job via informal channels or working as self-employed increase the risk of over-education, with a stronger effect during the recession. Among Ph.D related features, visiting abroad is always a driver to overcome any kind of job mismatch. Generally, benefiting from financial support is a propelling factor to reduce over-education; it is effective in reducing qualification mismatch especially during the downturn. In the light of the above findings, some policy advices are proposed.
