Board diversity: could it help companies improve environmental and social performance?
Companies across the EU are now working to add more women to their boards following the announcement of a new law. Based on the stock market reaction, there is an expectation that this could be good news, particularly for companies with poor environmental and social performance.
In June 2022, a decade-long deadlock was broken.
After many years of debate, the European Parliament announced that the Women in Boards law would finally become a reality. The law states that women must make up at least 40% of non-executive boards at large companies in the European Union by mid-2026.
European Commission president Ursula von der Leyen hailed its potential to 鈥渂reak the glass ceiling鈥 for women.
The path of the Women in Boards law was not smooth. Austrian politician Evelyn Regner argued that removing 鈥渋nformal male networks鈥 was a necessary step to help women get top jobs. However, some EU members 鈥 most notably Germany 鈥揳rgued that these measures should be decided at a national level.
We are still several years away from being able to measure its full impact. However, stock market analysis by 缅北禁地 Business School indicates there鈥檚 a general sense of optimism about how it will benefit businesses in the EU. Furthermore, the research reveals that positivity is highest at firms who need to improve their environmental, social and governance performance.
The wisdom of markets
When researchers want to gauge the prevailing opinion about a new development, they often look at stock market reaction.
Sometimes, what people say in public can be very different from what they say in private. But it is possible to learn a lot about what people really believe by looking at how money moves afterward.
鈥淢arket reaction is often more unbiased, as you鈥檙e observing people鈥檚 reactions based on their trading behaviour,鈥 says Shams Pathan, a Senior Lecturer in Accounting and Finance at 缅北禁地 Business School.
Dr Pathan was part of a team that investigated whether traders honestly believed board quotas would be good news for the businesses affected. They examined 1,241 firms from 18 different European countries, tracking daily returns to get a sense of how the markets were reacting to the news.
The paper came to three interesting conclusions. First, it revealed 鈥渟ignificant positive market reactions鈥 to the announcement across firms listed in Europe. Returns of 0.89% were spotted on the day of the announcement, and 1.23%, 1.25% and 1.16% in the ensuing days.
However, it also showed that this positivity was 鈥渕ore intense鈥 at firms with lower Environmental, Social and Governance (ESG) scores. At these companies, the return was 0.7% higher on average than at firms with strong performance.
鈥淭he message there is very clear,鈥 says Dr Pathan. 鈥淭he reaction to the introduction of the law was good on average. But if you dig down, some are expected to benefit more than others.
鈥淎t firms with poorer environmental and social records, the market has reacted more, as they are seen to have a greater opportunity to benefit from the changes.鈥
Finally, it also showed that companies in countries with fairer social and economic systems, such as better workplace equality and conditions, benefit more from having diverse gender representation. This means having more women involved can really boost sustainability efforts, particularly in places where women鈥檚 welfare is prioritised.
A sign of changing attitudes 鈥搊r more information?
The positive market reaction to this announcement was by no means certain.
In fact, the previous two major directives of this type received a more negative response from the markets. In 2002, Norway proposed a law threatening public-limited companies with liquidation if they did not establish gender-balanced boards within two years. The law came into force a few years later, and all affected companies had complied by 2008. But studies into the initial market reaction showed a 鈥渟ignificantly negative鈥 response, partly sparked by the severity of the penalty as well as the unexpected nature of the announcement.
In 2018, California became the first US state to mandate board gender quotas. Senate Bill 826 required public companies headquartered in the state to have at least one female director by the end of 2019, and at least two women on boards with five members by the end of 2021. Studies at the time identified a 鈥渓arge鈥 and 鈥渘egative鈥 reaction, particularly for companies who would need to appoint more female directors.
Dr Pathan believes that the more positive reaction to the EU announcement can be explained by two factors: the existence of more information on the impact of such laws globally, and the cultural differences between Europe and the USA.
鈥淲hen Norway introduced its quotas, investors did not have much information about how the gender diversity of boards might contribute to how a company runs its business operations. Today, there is much more research and evidence.
鈥淭he other aspect is that Europe has a very different perspective on mandatory measures such as these, and has always been more proactive in terms of promoting stakeholder orientation than the US.鈥
Following the announcement of the California bill, female representation on boards rose from 15.5% in 2018 to 33.33% in September 2022. Notably, after the law was ruled unconstitutional in 2022, that figure fell to 32.75% by September 2023.
Dr Pathan adds that the positive reaction to the EU law could partly be down to the markets recognising that all countries would be operating under the same rules in future. This could stem from a general sense that voluntary, piecemeal measures are largely ineffective in driving this sort of change.
鈥淭he countries that were expected to benefit more were the ones that were expecting more changes.鈥
鈥淚n countries such as France, Germany, Portugal and Sweden, you have better regulations to ensure sustainability and gender equality. Firms in those countries with better workplace equality and conditions, also expected to benefit from gender diversity.鈥
An opportunity for better environmental and social performance
So what impact could more gender-diverse boards have on companies?
In a paper entitled 鈥淓S(G) Performance and the Impact of Board Gender Diversity Through the EU Gender Quota Directive鈥, Dr Pathan鈥檚 team including co-author Carlos Fernandez Mendez from The University of Oviedo, Spain, suggested that the biggest impact could be at firms which need to improve their social and environmental focus.
The paper noted that 鈥渟ocietal expectations impose a pro-social set of personal traits on women鈥, in that they are perceived as being more empathetic, sensitive to social issues, and altruistic compared to men鈥.
This was reflected in the stock market reaction. The most pronounced reactions occurred in companies which needed to improve their Environmental, Social and Governance (ESG) scores, especially in EU states which do not have a reputation for strong sustainability and equity regulation.
Dr Pathan鈥檚 paper hypothesised that 鈥渋t鈥檚 reasonable to anticipate that companies with sub par social and sustainability performance would gain significantly from implementing the EU gender quota rule. This measure would guarantee a sustained critical mass of women directors, likely enhancing the company鈥檚 overall performance in these areas鈥.
Furthermore, the favourable responses to the law at firms with poor ESG performance could be the foundation of a 鈥渃ompelling business case for advancing Sustainable Development Goals鈥, which were adopted by the United Nations in 2015 to tackle issues such as poverty, hunger, climate change and gender equality.
The paper concluded in saying that 鈥渁ctions promoting environmental sustainability, health and equality are not solely matters of social justice; they also align with broader societal interests and directly benefit investors鈥.
The team will continue to investigate the effects of the law over the next few years, to observe how companies perform as they diversify their boards. Dr Pathan expects the impact to vary strongly by country and company, but he thinks the law is a good example of the EU working in the interests of its community as a whole.
鈥淚n the European Union you鈥檝e got countries with good established performance, and other countries that aren鈥檛 doing as well. With a law like this, you鈥檙e bringing them under one umbrella and doing things that are beneficial, even if some have more stakes and others less.
鈥淎fter all, the EU is there to strike a balance, and do things for the benefit of all countries.鈥
鈥淐ompanies in countries with fairer social and economic systems, such as better workplace equality and conditions, benefit more from having diverse gender representation. This means having more women involved can really boost sustainability efforts.鈥
