Evaluating the Impact of Board Diversity on Corporate Ethical Behavior and Transparency

Corporate governance changes have increasingly highlighted the need for diverse leadership frameworks to bolster ethical behavior and improve transparency across organizational functions. Board diversity—characterized by gender, educational background, and professional expertise—has become a crucial factor in effective governance, especially in developing economies like Bangladesh, where corporate malfeasance, accountability deficiencies, and disclosure inconsistencies persist. This research examines the influence of board diversity on corporate ethical conduct and corporate transparency. A quantitative research design was used, distributing 320 survey links to CEOs, compliance officers, and managerial professionals across diverse sectors; 170 valid responses were analyzed (n = 170). Correlation and regression analyses were conducted using SPSS version 26 at a 5% significance threshold. The results indicate that BD exerts a substantial and favorable impact on ethical conduct and transparency. The regression analysis reveals that BD accounts for 25.8% (R² = 0.258) of the variance in CEB, with a β coefficient of 0.381 (p < 0.01), and 28.3% (R² = 0.283) of the variance in CT, with a β coefficient of 0.399 (p < 0.01). Correlations indicate positive relationships between BD and both CEB (r = 0.421) and CT (r = 0.448). The results offer robust empirical evidence that diverse boards, with varied perspectives and diversified knowledge, improve ethical vigilance and reinforce disclosure policies. The study indicates that enhancing board diversity can function as an effective governance strategy to elevate ethical conduct, augment transparency, and restore stakeholder trust in Bangladeshi firms. Future avenues for study are suggested to enhance the understanding of governance reforms motivated by diversity.
