Empirical evidence indicates that Environmental, Social, and Governance (ESG) practices are associated with firm financial performance, but little is known about stock market participants’ behaviour towards ESG practices, especially in unfavourable settings, where the level of shareholders’ protection is relatively weak. In this article, we examine whether ESG performance provides shareholders with value-relevant information to help them in their equity pricing decisions. Using a cross-country sample of non-financial firms drawn from 10 Middle East and North African (MENA) countries between the period from 2013 to 2019, we find evidence, which is based on the price specification of Ohlson (1995) valuation model, that ESG performance practices are positively priced by market participants and add incremental information content to earnings and book value of equity (BVE). However, when we split the aggregate ESG performance into its components, governance practice is found to be more value relevant than social practice, while the environmental pillar is found to be value (ir)relevant to shareholders. Results using the return valuation model complement and validate the price model specification. Our results suggest that social capital and institutional structures prevail on firm environmental impact. These results are robust to a set of additional tests. Overall, our empirical results indicate that market participants incorporate ESG performance when assessing firm value for the MENA region. Our findings could have several implications for managers, stockholders and regulatory bodies.

Purpose This paper aims to highlight the relationship between the attributes of external auditor companies and voluntary corporate social responsibility (CSR) disclosures of audited firms using a sample of Abu Dhabi Securities Exchange (ADX)-listed companies. Design/methodology/approach Based on a sample of 410 firm-year observations for the period 2010–2016, this study first computes an eight-item CSR disclosure index, then ran a multivariate regression analysis between CSR disclosure scores and external auditor attributes, along with client firm characteristics and additional control variables. Finally, this paper performs various additional robustness checks. Findings The results reveal that external auditor attributes have a significant impact on shaping the CSR disclosures of ADX-listed firms. Overall, auditor age, size, industry specialisation and portfolio diversification positively affect the level of customers’ CSR disclosures. By contrast, the magnitude of audit fees and auditor experience in the UAE has no impact on the CSR disclosures of ADX-listed firms. This study controls for client firm size, financial leverage, ownership concentration and the proportion of independent directors on companies’ board of directors. The results remain robust to additional sensitivity checks such as audit company CSR practices, extreme quartiles of CSR disclosures and the panel data estimation method. Research limitations/implications The research exhibits some limitations. First, this paper uses a simple index to measure CSR disclosures based on previous empirical studies, especially those related to emergent markets, which are not free from bias due to the lack of voluntary disclosure transparency for some companies listed on ADX. Second, although this study uses a seven-year observation period, the total number of observations remains limited due to ADX size. Third, other context-specific disclosures should be included such as cultural and governance variables (royal families ownership). Practical implications The study highlights the role of external attributes that can affect companies’ CSR disclosure policy, rather than firm-specific factors. The study also reshapes the concept of auditor quality beyond the dichotomy (“Big Four”/non-Big Four) used in the current literature. Originality/value The research adds to the current literature on CSR by revealing the impact of external auditor attributes on client firm CSR disclosure policy in an emerging market, the ADX.

Purpose This paper aims to explore whether environmental, social and governance (ESG) performance is positively associated with firm investment efficiency (IE) in emerging economies. It also examines whether board cultural diversity can moderate the ESG–IE relationship. Design/methodology/approach This paper uses a cross-country sample of listed firms located in seven emerging countries over the 2011–2019 period. The authors use a fixed effect panel regression to empirically test the hypotheses. The authors also use a lagged model and a Heckman’s (1979) two-stage procedure to mitigate potential endogeneity issues. In addition, a two-stage least squares regression analysis was done as an additional robustness check. Findings This study finds that firms with stronger ESG performance have a higher investment efficiency. Interestingly, this study finds that board cultural diversity negatively moderates the impact of ESG performance on IE for firms operating in settings prone to overinvestment. This result suggests that ESG performance plays a less important role in mitigating managers' tendencies to overinvest when corporate boards have more foreign directors. However, the authors do not find such evidence in firms prone to underinvestment. These findings hold after using an alternative measure of IE and controlling for endogeneity concerns. Originality/value This paper adds to the existing body of knowledge in three dimensions. First, to the best of the authors’ knowledge, this is the first cross-country study that investigates the linkage between ESG performance and corporate IE in the context of emerging countries. Second, the authors have enriched the prior literature by examining the moderating effect of board cultural diversity on the positive association between ESG performance and corporate IE. Finally, this study has important implications for policymakers and capital suppliers in emerging countries, which strive to facilitate the efficient allocation of scarce resources.
