Board gender diversity and firms’ equity risk

Abstract

Purpose

There is a growing attention toward the importance of women’s participation on corporate boards in enhancing board governance and decision-making quality. The literature lacks sufficient empirical evidence on the relationship between women’s involvement on boards and firms’ risk. The purpose of this paper is to investigate the influence of board gender diversity on firms’ risk.

Design/methodology/approach

This paper explores the influence of women’s participation on corporate boards on firms’ stock return volatility. The examined firms are all non-financial firms listed on the FTSE 350 index between 2008 and 2013. The Bloomberg database is used to collect the needed variables. Panel data are employed through a regression model to estimate relationships. One-step Arellano and Bond and the generalized method of moments are used to control for reverse causality and the existence of endogenous variables.

Findings

The results suggest that women’s participation on corporate boards favorably impacts firms’ risk by reducing firms’ stock return volatility. The authors also find that the influence of women on reducing stock return volatility is higher in four particular industries recognized by their close proximity to consumers (consumer goods, consumer services, health care, and utilities).

Originality/value

The study contributes to the growing literature on women on boards and offers solid empirical evidence of the correlation between board gender diversity and firms’ risk. The empirical results provide economical and statistical validity to the “voluntary business-led” approach of Davies reports and to the recommendation by the UK Corporate Governance Code 2014 on the favorable influence of board gender diversity for effective functioning.
