Stock market response to the statement on the purpose of a corporation: A vindication of stakeholder theory
研究2019年美国商业圆桌会议181位CEO签署的“为所有利益相关者创造价值”声明对签署公司股价的影响，发现投资者反应积极，且签署后公司股票回购减少，但投资者未因此退缩。
Abstract Research Question/Issue On August 19, 2019, the Business Roundtable (2019) released a statement signed by 181 chief executive officers (CEOs) of well‐known US corporations, in which they pledged “a fundamental commitment” to “deliver value to all” stakeholders. This study examines the stock market reaction to this new statement on the purpose of a corporation. Research Findings/Insights Based on a sample of 163 publicly listed companies that signed the pledge, the results show that investors react positively to a firm's pledge in the days surrounding the statement release. The consensus among stock market investors was robust, characterized by the low volatility in the share price post‐announcement date. The decision by these companies, though intended to maximize the wealth of all stakeholders, rather than shareholders alone, carries an opportunity cost. Specifically, a post‐announcement decline in share buybacks by pledge firms relative to control firms is observed, though investors embracing stakeholder theory appear undeterred by the reduction in distributions. Theoretical/Academic Implications This study provides empirical support that, in the evolving business environment, companies must emphasize issues that concern customers, employees, non‐governmental organizations (NGOs), and the government. Failure to prioritize these issues may engender public backlash, especially in the age of social media. However, the attention to stakeholders is compatible with the focus on shareholder performance. Performance suffers when customers leave, workers feel dissatisfied, NGOs call for boycotts, and governments levy fines. Corporations seeking to increase shareholder wealth will need to fully embrace stakeholder concerns. Practitioner/Policy Implications This study shows that adopting a stakeholder perspective unlocked value that would not have been achieved had the focus remained on shareholder primacy. The excess values may derive from greater customer loyalty, improved employee motivation, better supplier relations, supportive financiers, maximizing revenue, minimizing costs, and/or yielding higher profits. Shareholders anticipate greater long‐term value from companies emphasizing employees, communities, supply chain, financiers, and shareholders.
