Human Capital Investments and the Performance Paradox in Emerging Markets: A Re-examination of Training, Compensation, and Financial Outcomes in Nigerian Insurance Firms

Abstract

Despite theoretical expectations that human capital investments should enhance organizational performance, empirical evidence from emerging markets often contradicts this premise. This study re-evaluates the relationship between human capital expenditures and firm-level financial performance within the Nigerian insurance sector. Using panel data from 21 listed insurance firms over a 12-year period (2012–2023), the study employs Estimated Generalized Least Squares (EGLS) random-effects models to assess the influence of training and development costs (TDC) and employee compensation costs (ECC) on return on assets (ROA) and net profit margin (NPM). The findings reveal that neither TDC nor ECC exerts a statistically significant impact on ROA or NPM, contradicting core propositions of human capital theory and the resource-based view. Moreover, the volume of insurance policies exhibits a significant negative relationship with NPM, suggesting operational inefficiencies associated with scale expansion. The study uncovers a “performance paradox,” where substantial human capital spending does not translate into immediate financial gains. It highlights the structural, institutional, and measurement complexities that characterize developing economies and offers theoretical, managerial, and policy implications for rethinking human capital valuation and strategic alignment in the insurance industry.
