Standard analysis of the labour market tends to focus on quantity, but there is an increasing interest in the quality of jobs created. However, there is no consensus on the conceptualisation and operationalisation of QWE, demonstrating not only the novelty of research and policy development in this area, but also the considerable challenges in measuring this concept (Muñoz de Bustillo et al. 2011).
