First, given that job-education mismatch can be observed only among employed individuals, the job-education mismatch equation should be estimated on the condition of sample-selection based on unobservable factors that affect both employment decisions and job quality (following Büchel & Van Ham, 2003, Jauhiainen, 2011, Rubb, 2011, Devillanova, 2013, Sanromà & Ramos 2013and Croce & Ghignoni, 2013. Second, we consider private transport availability to represent a potential determinant of both employment and job-education mismatch, which is also likely to be related with unobservable factors that affect these two labour market outcomes (as noted by Raphael & Rice 2002, Gurley & Bruce 2005, Baum 2009, Bansak et al, 2010.…”
