Determinants of health-system efficiency: evidence from OECD countries.

This paper analyzes the most important determinants of healthcare efficiency across OECD countries. As previously documented in the literature, we first provide evidence of significant differences in the cross-country level of efficiency in healthcare provision. We then investigate how improvements in efficiency can be achieved by considering alternative efficiency indices (parametric and non-parametric) and a novel dataset with information on the characteristics of healthcare systems across OECD countries. Our empirical findings suggest a positive correlation between policies such as increasing the regulation of prices billed by providers and reducing the degree of gate keeping and the efficiency of national healthcare systems.
