This volume compiles 11 articles on the disparity between skill supply and skill demand in labor markets, examining the link between education and skills and the causes and consequences of different types of skill mismatch, focusing on the ways workers can develop their skills and how workplaces use or not use them. Researchers mainly from Europe consider how graduate jobs can be defined, the labor market decisions and outcomes of graduates, the determinants and consequences of the overeducation wage penalty and underskilling, the wage return of skills, the impact of skill mismatch on aggregate productivity, and the role of work-related training and job complexity in skill development.
