This study investigated the impact of human capital investment on economic resilience in
Nigeria between 1990 and 2023. The data utilized were sourced from the secondary sources
like Central Bank of Nigeria publications, and World Bank World Development Indicators
(WDI). Government expenditure on education and health were used as proxies for human
capital investment, while real GDP and the human development index (HDI) served as
development indicators (economic resilience). A long-run relationship was found to exist
between human capital investment variables and the economic development variables in the
models. The study applied the novel dynamic ARDL simulation model. The results of the study
revealed that education spending had a positive but insignificant effect on real GDP and a
negative impact on HDI. Conversely, health expenditure negatively affects real GDP, but
significantly improves HDI. The outcomes of the Counterfactual shock analysis, showed that
both increases and decreases in human capital investment reduce real GDP, while only health
expenditure positively influences HDI. These findings suggest that the effectiveness of human
capital investment in Nigeria is undermined by inefficiencies, calling for a reallocation of
resources toward more outcome-oriented and productivity-linked strategies. The study
concluded that, human capital investment is vital for economic resilience, but in the Nigerian
context, its impact depends on how effectively education and health resources are allocated
and managed. The study therefore recommended, the need for Nigeria to shift from inputdriven (spending) approaches to outcome and impact-driven investment strategies in education
and health if it is to build a resilient, inclusive, and sustainable economy.
