Sources of public service improvement: A critical review and research agenda

Evidence from sixty-five empirical studies of the determinants of public service performance is critically reviewed. The statistical results are grouped on the basis of five theoretical perspectives: resources, regulation, markets, organization, and management. The analysis suggests that the most likely sources of service improvement are extra resources and better management. A research agenda for further work is identified, and recommendations are made to enhance the theoretical and methodological quality of studies of public service improvement.
