Constraints on Angolan manufacturing enterprise labour productivity improvement

The study analysed factors behind labour productivity among manufacturing firms in Angola. Many studies used output per worker. The current study used sales per labour cost to reflect labour quality. Simultaneous quantile regression dealt with ordinary least square shortfalls. However, no variable was significant in the lower distribution of labour productivity. Highly educated managers were less productive than primary school managers, and large firms were more productive. Innovative and subcontracting firms were more effective than non-innovative and non-cooperative firms. Infrastructural bottlenecks reduced productivity among firms, while trade regulations supported performance for others. Local and central governments should improve infrastructure, and minimise customs and trade regulations. Future studies should investigate factors behind negative education influence on labour productivity by using output per worker. The managerial recommendations have also been provided.
