The Impact of Governance Quality on Risk Management of Listed Firms in Nigeria

This study investigates the impact of governance quality on the risk management practices of listed firms in Nigeria over the period 2011–2025. Drawing on agency theory, stakeholder theory, and enterprise risk management (ERM) frameworks, the paper argues that stronger governance mechanisms enhance the effectiveness of risk management processes, thereby reducing firm-level vulnerabilities in an emerging market characterized by institutional fragility and macroeconomic volatility. Using an ex-post facto research design and panel regression analysis on a sample of 148 listed firms on the Nigerian Exchange Group, the study examines the relationship between a composite governance quality index—capturing board independence, board diversity, audit committee effectiveness, CEO non-duality, and regulatory compliance—and a multidimensional risk management index. The analysis controls for firm size, leverage, liquidity, growth opportunities, industry type, GDP growth rate, inflation rate, interest rates, board size, ownership structure, firm age, and audit quality. The results reveal that governance quality exerts a statistically significant positive impact on risk management effectiveness. Board independence and audit committee effectiveness emerge as the most influential governance dimensions. Among the control variables, firm size, audit quality, and leverage are significant predictors of risk management outcomes, while macroeconomic controls—particularly inflation and interest rates—demonstrate meaningful moderating effects. Post-estimation diagnostics, including the Hausman test, Breusch-Pagan Lagrange Multiplier test, tests for heteroscedasticity, serial correlation, and multicollinearity, confirm the robustness of the findings. The study contributes to the governance-risk nexus literature by providing comprehensive evidence from a Sub-Saharan African context, challenging the assumption that governance codes alone guarantee effective risk oversight. The findings carry implications for regulators, corporate boards, institutional investors, and policymakers seeking to strengthen corporate resilience in Nigeria's evolving capital market.
