In this paper, we analyse the effects of public expenditures and their structure on productivity growth in industry and services in the European Union (EU) countries. We also control for the share of expenditures made by central governments. We find that productivity growth in industry decreases with government expenditures on environmental protection and increases with the decentralisation of government expenditures on recreation, culture and religion. As for services, productivity growth declines with military expenditures and increases with the centralisation of expenditures on public order and safety, and with the decentralisation of expenditures on economic affairs. The former two effects are mainly noted in Eastern European countries, while the latter is stronger in Western Europe. Lower corruption increases productivity growth. Furthermore, our estimates suggest that there is a convergence in productivities across EU member states, with convergence faster in the service sector than in the industrial sector. These findings carry important policy implications.
