Decentralization and equity: public health expenditure in the municipalities of the Province of Buenos Aires

In this paper we analyze the degree of equity in access to the public health care system in the Province of Buenos Aires (Argentina). Through a quantitative retrospective study, we analyze the inequalities in the distribution of the total public health expenditure per capita. This variable is used as a proxy for the ability of the inhabitants of each jurisdiction to access health care services. The results indicate the existence of large disparities in the levels of expenditure devoted to the population without health coverage. Moreover, the existence of greater health care needs (estimated using infant mortality rates and percentage of homes with basic needs unmet) does not translate into higher levels of public expenditure. Finally, we detect a positive association between the relative wealth of municipalities (measured by the gross geographic product per capita) and the public health expenditure per capita.
