Product market competition, board gender diversity and corporate sustainability performance: international evidence

Abstract

Purpose This study aims to investigate whether board gender diversity is associated with corporate sustainability performance and whether industry-level product market competition moderates the effect of board gender diversity on corporate sustainability performance. Design/methodology/approach This study uses international data extracted from global ESG data set from Thomson Reuters (Refinitiv) database. Using data of 23,137 firm-year observations from 37 countries, the authors perform regression analyses to examine the hypotheses. Findings The findings show that firms with high board gender diversity exhibit high corporate sustainability performance. The authors also find firms in highly competitive industries to have low corporate sustainability performance. In highly competitive industries, the positive relationship between board gender diversity and corporate sustainability performance is weakened. The results are robust to various specification tests such as alternative measures for corporate sustainability performance, board gender diversity, product market competition and also the use of propensity score matching to address endogeneity issue. Overall, the results support the prediction that board diversity and product market competition play a substitutive role in influencing corporate sustainability performance. Research limitations/implications This study offers empirical evidence that the appointment of female directors is a useful way to improve a firm’s corporate sustainability performance, hence, providing significant benefits in terms of stakeholders’ values and corporate reputation. Practical implications This study provides useful insights to investors and policymakers that intense industry competition might mitigate the role of board governance, particularly board gender diversity, in enhancing corporate sustainability performance. Originality/value Using an international data set, where the observations operate in various market and institutional differences, this study is able to extricate the positive impact of board gender diversity and product market competition on corporate sustainability performance. This study corroborates evidence that sustainability strategy and initiatives are reflections of integrated factors, including corporate governance as internal driver and market forces faced by firms as external driver.

Gender Diversity in the Boardroom and Corporate Cash Holdings: The Moderating Effect of Investor Protection

“…Following prior studies (e.g., Alves et al 2015;Kamarudin et al 2021;Smith et al 2006), we measure board gender diversity based on the proportion of women on the board of directors by dividing the number of female board members by the total number of directors (DIVBOD). Second, for the robustness analysis, we follow Campbell and Mínguez-Vera (2008) and Miller and del Carmen Triana (2009) by calculating BLAU, which is based on the Blau (1977) index of heterogeneity.…”

“…We have also included a country-level variable, FEMLAB, to control the country variable effect on board gender diversity and the CCH relationship. The model further includes fixed effects to control for unobserved time and industry-wide common factors (Wan Ismail et al 2021).…”

Corporate Sustainability Reporting and Firm’s Financial Performance in Emerging Markets

“…This is due to the fact that in preparation of sustainability reports, firms need to face tensions in balancing the often divergent economic, social, and environmental goals. To a certain extent, firms may be lured towards 'greenwashing', as seen in the case of Volkswagen emission scandals, where incomplete or false information was intentionally provided to legitimately appear sustainability-oriented in order to gain economic benefits (Kamarudin et al, 2021). In addition, a study by Chen et al (2015) showed that some firms tended to apply for repetitive disclosures in order to suppress other disclosures, providing evidence for the manipulative power of management regarding these reports.…”

Drivers of environmental and social sustainability accounting practices in Nigeria: a corporate governance perspective

“…Conversely, when PEU is low, predictions about the market may be relatively accurate, thus diminishing the need for external and ex-ante information (Gul & Chia, 1994;Naidenova, 2022), and lower usage of SAP. A robust corporate governance apparatus will institutionalise structures to regularly scan the environment to ensure the organisation anticipates changes and implement measures that ensure organisational survival (Kamarudin et al 2021). Therefore, H6: High level of perceived environmental uncertainty will drive SAP implementation…”
