This paper analyses the effect of job accessibility on job-education mismatch in the metropolitan area of Barcelona with regard to both public and private transport. Transit accessibility is defined in terms of the spatial distribution of employment relative to travel time by public transport, whereas accessibility by private transport is approximated by car availability. The results obtained from a joint model for car ownership, employment selectivity and mismatch confirm that car availability matters for job-education mismatch. Moreover, public transport connectivity to job locations favours the matching between schooling and occupation in the urban labour market.
