Researchers working in this area use approaches from economics, sociology and psychology to study how the labor market and the world of work are affected by global developments – such as increased international division of work, increasing migration, and demographic, technological and organizational change – and how politics can react to them. The focus of this work is on atypical employment (such as agency work or solo self-employment), institutional frameworks (e.g. labor law), training and professional development, changing requirements for work, labor mobility, and wage differences and wage developments.
