Executive Pay Disparity, Employee Motivation, and Governance Outcomes in Nigerian Banks

This study examines the effects of executive pay disparity on employee motivation levels and downstream governance outcomes in Nigerian commercial banks. Executive pay disparity, defined as the ratio of chief executive officer remuneration to median employee pay, has risen significantly in the Nigerian banking sector over recent years, generating growing attention from regulators, shareholders, and civil society. Pay disparity is theorised to affect employee perceptions of fairness, organisational commitment, and productivity, creating governance risks through elevated staff turnover, fraud vulnerability, and reputational exposure. Drawing on tournament theory, equity theory, and the behavioural governance literature, this study investigates the relationship between pay disparity ratios reported in bank remuneration disclosures and employee motivation scores collected through validated survey instruments administered to 300 banking employees across ten deposit money banks. Mediation analysis using structural equation modelling tests whether employee motivation mediates the relationship between pay disparity and governance outcomes measured by internal fraud incidence, customer complaint resolution rates, and staff turnover. The study addresses an unexplored dimension of remuneration governance in the Nigerian banking literature, moving beyond the executive-level focus of existing studies. Findings will assist the Central Bank of Nigeria, bank remuneration committees, and human resource governance practitioners in designing equitable pay structures.
