The chapter examines how firms’ labour flexibility strategies and capital structure are related with firm performance, based on a firm‐level dataset on formal private sector enterprises in 132 countries. It finds that “investing in people” whether through a strategy of functional labour flexibility or financing decisions for securing working capital (i.e. funds for day‐to‐day operations), is the key feature of enterprises with higher competitiveness and better job quality. Through the provision of formal training for permanent employees, functional labour flexibility is associated with higher productivity and wages, while numerical labour flexibility, enhanced through the use of temporary employment, is associated with lower productivity and wages. Additionally, securing external formal funding to provide working capital is important. Those enterprises that use bank loans for working capital more intensively enjoy higher productivity and pay higher wages, while those that rely more heavily on internal funds are less productive and pay lower wages. In addition, the positive relationship between the use of bank loans and wages is not observed when bank loans are used for new purchases of fixed assets, suggesting that securing formal external funding for new investments is not automatically linked to better job quality.
