The mismatch between the education level of workers and that required by the jobs available in the labour market represents one of the most debated dimensions of the education and skills mismatch. Both the horizontal and vertical dimensions of the mismatch are expected to increase in the near future. First, many observers believe that the horizontal mismatch, which happens when the level of schooling is appropriate but the type of schooling is not (Sloane 2003), is bound to increase due to two main factors: first, the increasing complexity of the industrial structure, which causes a mismatch between the composition of labour demand and supply by types of education and skills; and second, and the insufficient coordination of education institutions with labour market evolutions (see, among others, Robst 2007; Nordin et al. 2010).
