In this article we mobilize a variegated capitalism approach to understand the development of the Norwegian temporary staffing industry. From this perspective, national temporary staffing industries are understood as contested multi-actor and multiscalar institutional fields. The analysis explores the key actors and regulatory conditions that have interactively produced this field in the Norwegian context since initial deregulation in 2000, paying particular attention to the active role played by agencies and their collective organizations. In our account, the tight regulatory conditions for temporary staffing in Norway emerge as the main mobilizing issue for the agencies, as well as other political actors such as trade unions. It is argued that the nature of national labour laws, and struggles thereon, are defining characteristics which set the Norwegian market apart from the neighbouring Swedish staffing market. The Norwegian case enables us to contribute to the wider economic geography literature on temporary staffing markets by demonstrating the fundamental importance of national regulatory processes and the contested political processes that underlie regulatory change. It also demonstrates how national distinctiveness is actively produced in relation to extra-national dynamics in terms of both regulatory imperatives (e.g. via the EU's Temporary Workers Directive) and processes of migration. Overall, we demonstrate how national staffing markets are highly dynamic, multi-scalar institutional configurations whose particularities and complexities defy attempts to generalize across groups of seemingly "similar" national economies.
