Abstract: Research Question/Issue: The post-Apartheid South African (SA) corporate governance (CG) model is a unique hybridisation of the traditional Anglo-American and Continental European-Asian CG models, distinctively requiring firms to explicitly comply with a number of affirmative action and stakeholder CG provisions, such as black empowerment and HIV/Aids. This paper examines the association between a broad CG index and firm value in this distinct corporate setting. Research Findings/Insights: Using a sample of 169 post-Apartheid SA firms from 2002 to 2007, we find a significant positive association between a broad CG index and firm value, as proxied by Tobin’s Q. Distinct from prior studies, but consistent with political cost, legitimacy and resource dependence theories, we find that compliance with affirmative action CG provisions impacts positively on firm value. The results are robust across a number of econometric models that control for different types of endogeneity, accounting and market-based firm valuation measures. Theoretical/Academic Implications: The paper contributes to the literature on the association between compliance with codes of good governance and firm value by specifically modelling the relationship within a unique institutional, legal and CG environment. Distinctively, we contribute to the literature by showing how affirmative action and stakeholder CG provisions impact on firm value. Practical/Policy Implications: The results have important policy implications for companies and regulators. They suggest that investors reward firms with better CG practices with higher market valuation, providing support to the efforts by various stakeholders at improving CG standards in SA companies. The results also suggest that SA companies who pay serious attention to complying with affirmative action and stakeholder CG provisions may reap benefits in the form of higher firm value.
