The population in Sub Saharan Africa (SSA) suffers poor
health as manifested in high mortality rates and low life expectancy. Economic
growth has consistently been shown to be a major determinant of health
outcomes. However, even with good economic growth rates, it is not possible to
achieve desired improvements in health outcomes. Public spending on health
(PSH) has long been viewed as a potential complement to economic growth in
improving health. However, the relationship between PSH and health outcomes is
inconclusive and this inconclusiveness may, in part, be explained by
governance-related factors which mediate the impact of the former on the
latter. Little empirical work has been done in this regard on SSA. This paper
investigates whether or not the quality of governance (QoG) has a modifying
effect on the impact of public health spending on health outcomes, measured by
under-five mortality (U5M) and life expectancy at birth (LE), in SSA.
Using two staged least squares regression technique on panel
data from 43 countries in SSA over the period 1996–2011, we estimated the
effect of public spending on health and quality of governance U5M and LE,
controlling for GDP per capita and other socio-economic factors. We also
interacted PSH and QoG to find out if the latter has a modifying effect on the
former’s impact on U5M and LE.
Public spending on health has a statistically significant
impact in improving health outcomes. Its direct elasticity with respect to
under-five mortality is between −0.09 and −0.11 while its semi-elasticity with
respect to life expectancy is between 0.35 and 0.60. Allowing for indirect effect
of PSH spending via interaction with quality of governance, we find that an
improvement in QoG enhances the overall impact of PSH. In countries with higher
quality of governance, the overall elasticity of PSH with respect to under-five
mortality is between −0.17 and −0.19 while in countries with lower quality of
governance, it is about −0.09. The corresponding semi elasticities with respect
to life expectancy are about 6 in countries with higher QoG and about 3 in
countries with lower QoG.
Public spending on health improves health outcomes. Its
impact is mediated by quality of governance, having the higher impact on health
outcomes in countries with higher quality of governance and lower impact in
countries with lower quality of governance. This may be due to increased
efficiency in the use of available resources and better allocation of the same
as QoG improves.
Improving QoG would improve health outcomes in SSA. The same
increase in PSH is twice as effective in reducing U5M and increasing LE in
countries with good QoG when compared with countries with poor QoG.
