The Board of Directors as a Driver of Corporate Equality: Diversity, Inclusion, and Personal Development

Grounded in stakeholder and social categorisation theories, this study addresses the limited European evidence regarding how board composition and functioning drive corporate equality—a multidimensional construct encompassing diversity, inclusion and people development. We examined the effects of seven board characteristics—gender diversity, the proportion of non-executive directors, tenure, size, cultural diversity, meeting attendance and remuneration structure—corporate equality and its three constituent pillars. Our analysis drew on a panel of 1797 firm–year observations from the Euro Stoxx 300 (2012–2023), extracted from Refinitiv Eikon, using OLS, fixed-effects and random-effects models selected via the Hausman test and AIC/BIC criteria, with firm-level controls and year- and industry-fixed effects. The results demonstrate that gender diversity, non-executive participation and regular meeting attendance are positively associated with corporate equality, particularly its diversity and inclusion dimensions, whilst tenure has no significant effect. Board size affects only people development; cultural diversity enhances the diversity pillar but diminishes the people development pillar; and remuneration schemes are negatively associated with overall equality. The principal contribution involves operationalising ‘corporate equality’ as a multidimensional construct within the European context and identifying differential effects across pillars. These findings offer practical guidance for regulators and organisations seeking to align board composition and governance practices with inclusion objectives, emphasising the importance of gender diversity, independent directors, consistent meeting participation and remuneration policies aligned with social objectives.
