RT Conference Proceedings T1 Socio-economic determinants of efficiency in reducing child mortality in developing countries A1 Ortega-Aguaza, Bienvenido A1 Sanjuán-Solís, Jesús Carlos A1 Casquero-Tomás, Antonio K1 Niños - Mortalidad AB Efficiency issues in health investments have received increasing attention, mainly as aresult of the growing amount of resources invested in developing countries and theirmixed impacts on outcomes. The empirical literature has suggested that, althoughgovernment spending on health care improves the health status of the population, societycan potentially gain more through the more efficient assignment of health resources. In this context, this paper aims to: firstly, to analyse whether developingcountries can further reduce child mortality by using the available resources moreparsimoniously; and secondly, to identify the (non-discretionary) socio-economic factorsthat could be affecting this process. More specifically, this paper aims to explain whysome countries are more efficient than others in converting inputs (physician density andrelative total health expenditure) into a health outcome: the under-five mortality rate(U5MR). The database usedin the estimations comprised 47 developing countries with data for the periods 2000-2004, 2005-2009, and 2010-2012. The findings suggest that greater efficiency in theprovision of immunization, better quality government, and lower income inequality aredirectly related to efficiency in the use of inputs to reduce the U5MR.
