The purpose of this study is to conduct a cross country study in order to analyse descriptively and econometrically the relationship between human resources for health (i.e. density of health workers) and population health outcomes, focusing especially on the burden of disease (i.e. disability-adjusted life years (DALYs)), and compare these results with the results for other outcome indicators previously analysed in the literature (i.e. vaccination coverage and mortality). Finally, the analysis will be extended considering separately the DALYs of the three different groups of the burden of disease as the dependent variable (i.e. communicable, non-communicable diseases, and injuries), in order to study the possible different effects of the variable of interest (i.e. health
workers) on these different groups of diseases.
