The study empirically investigated the link among healthcare expenditures, health outcomes and economic growth in a panel of 15 countries of ECOWAS within the periods, 2000-2020. The study decomposes healthcare expenditures into four components: national, public, private and external; health outcomes into life expectancy, infant mortality, maternal mortality and under-five mortality; while economic growth is measured by gross domestic product per capita. The parameters are estimated using the pooled mean group (PMG) and granger causality estimators. Based on the pooled mean group results, it was discovered that healthcare expenditure is an important predictor of life expectancy. Thus, healthcare expenditure positively and significantly influences life expectancy in ECOWAS. On the contrary, healthcare expenditures have a negative impact on infant mortality. Meanwhile, the effect of healthcare expenditure on maternal mortality rate and under-five mortality rates is statistically significant, albeit has mixed signs. It was further discovered that healthcare expenditure positively and significantly impacted economic growth. As regards the causality test, income per capita has a bi-causal link with national, private and external healthcare expenditure, while a one-way causal link was found from public healthcare expenditure to per capita income. Also, a uni-directional link exists between healthcare expenditures and life expectancy. Equally, there exist a one-way causation from health outcomes to income per capita. The study recommends that government should increase budget allocation into health sectors as presented during Abuja declaration in April 2001, so as to achieve better health outcomes and sustainable economic growth.
