Closing the gender wage gap in the boardroom: the role of compliance with governance codes

Abstract

Purpose

This paper aims to analyse the gender wage gap (GWG) in the board of directors at the executive-director level. The authors aim to answer two questions: (1) Is the GWG explained by differences between males and females, by discriminatory causes or by both? and (2) what are the main factors that cause or increase the existence of GWGs? Specifically, the authors pay special attention to compliance with good governance codes as a fundamental variable in explaining the GWG.

Design/methodology/approach

The study uses a sample of directors in Spanish companies listed on the continuous market from 2013 to 2021 and uses Blinder–Oaxaca decomposition and unconditional quantile regressions to analyse the GWG.

Findings

The findings demonstrate both discriminatory reasons and differences between individuals when explaining the GWG and showing that compliance with remuneration practices issued by good governance codes considerably reduces the GWG for all remuneration components.

Practical implications

The study confirms adequacy of regulator remuneration recommendations but highlights GWG persistence within boards. To counter this, enforcing pay transparency aids female directors’ advancement, reducing bonuses’ impact on wage disparity, necessitating monitored laws for fairer compensation systems and meeting 40% of women directors’ proposals.

Social implications

Primarily, this study significantly influences public attitudes towards GWG. Specifically, it calls for companies to not only increase female leadership representation but also to ensure equitable remuneration aligned with their male counterparts, conduct regular pay equity assessments, implement pay transparency policies and support work-life balance through flexible hours and parental leave. Furthermore, the work serves as a crucial resource for female directors, empowering them to advocate for their rights in the context of GWG.

Originality/value

This research offers nuanced insights into the GWG in corporate boards, corrects the main limitations of previous studies and calls for regulatory reinforcement and the active involvement of female directors and firms in creating equitable policies.
