Examining the relationship between CEO power and modern slavery disclosures: The moderating role of board gender diversity in UK companies

Abstract Drawing on agency and gender socialisation theories, this study examines the effect of Chief Executive Officer (CEO) power on corporate modern slavery disclosures (MSD) and investigates whether board gender diversity might influence this relationship. Based on a sample comprising the Financial Times Stock Exchange (FTSE) 100 companies from 2016 to 2020, the findings indicate that, although there has been progress in corporate transparency concerning modern slavery, a significant gap persists in the reporting on the measurement and monitoring of the effectiveness of their policies. This may stem from powerful CEOs' desires to maintain a positive corporate image, leading to minimal disclosure of potentially damaging information. The fixed effects panel regression analysis reveals a negative relationship between CEO power (CEOP) and the extent of modern slavery disclosures (MSD), with a significant moderating effect observed when female board representation is substantial. This evidence suggests that female board members may challenge groupthink and introduce diverse perspectives that can alter the board's dynamics, potentially mitigating the negative impact of CEOP on issues like modern slavery disclosure by encouraging more ethical and collective decision‐making. This research underscores the need for greater transparency and accountability in addressing modern slavery and promoting more responsible business practices.
