RECENT studies show companies violate environmental regulations when financial managers are overconfident.
These environmental violations harm the company’s long-term performance, particularly in terms of its credit ratings.
Credit ratings evaluate the creditworthiness and financial health of financial institutions, companies, and governments, playing a crucial role in instilling confidence in lenders and investors.


The study examined nearly 600 companies in the United States over a 17-year period and discovered that firms in states with laws mandating consideration of all stakeholders’ interests, rather than just those of shareholders, are more effective at averting financial problems and safeguarding their financial health.
Researchers at the University of East Anglia (UEA) and Heriot-Watt University led the study, collaborating with colleagues from Coventry and Bangor Universities, as well as the University of Aberdeen in the UK.
While most earlier research concentrated on chief executives, this study examined Chief Financial Officers (CFOs), the leading financial decision-makers in organisations.
The results are published today in the European Management Review journal.
Dr Yurtsev Uymaz of UEA’s Norwich Business School said: “What’s new here is that we show CFOs’ personalities – especially if they’re overconfident – can lead to risky decisions that harm both the environment and the company, we also show that certain state laws can help keep those risks in check.”
Professor Patrycja Klusak, an expert in credit ratings agencies and professor of accounting and finance at Heriot-Watt University’s Edinburgh Business School, said: “This matters because it connects executive behaviour with real-world outcomes like pollution and financial damage.
“It suggests that paying attention to the personality traits of company leaders – especially CFOs – is important.
“It also shows that stakeholder-focused laws can help prevent bad behaviour and protect both the public and investors.”
Considering the significant influence of senior executives’ overconfidence bias on companies’ environmental initiatives, the authors emphasise the necessity of enhancing internal controls and oversight for crucial decisions, ensuring active involvement from all stakeholders.
Dr Uymaz said: “Constraining managerial overconfidence through regulation can improve investor confidence and trust, as it helps counter the tendency toward short-termism driven by this overconfidence bias.
“In particular, firms with overconfident CFOs may benefit more from stakeholder-oriented laws while also incurring higher penalties for environmental violations.
“Our findings are also valuable to stakeholders such as employees, customers, investors, and local communities, whose trust and well-being might be at risk.
“If the cognitive and psychological biases among management play a critical role in firms’ environmental decisions, addressing these biases can shift managerial and organisational incentives, with far-reaching implications not only for financial markets but for society.”
The research highlights the crucial roles that board members play, as they can significantly influence firms’ environmental impacts.
Although managerial overconfidence may foster growth, it can harm environmental performance if not adequately balanced and managed.
The authors emphasise that this issue is especially critical at the firm level, as environmental misconduct can result in considerable reputational and litigation expenses.
The team examined financial records, executive conduct, and environmental violation history for US companies from 2006 to 2022.
They then analysed the relationships between these factors and assessed the impact of stakeholder laws on outcomes.
The sample consisted of firms from the air transport, manufacturing, petroleum, technology, and telecommunications sectors.
Researchers discovered that Brown industries (specifically air transport and petroleum) breached environmental regulations about 62% of the time, whereas green sectors (technology and telecom) had a violation rate of only 10.6%.
Some industries present a higher risk of environmental degradation due to their inherent business nature, which the study took into account.
