In new research, Michele Fioretti, Victor Saint-Jean, and Simon Smith show that NGO activism follows a clear economic logic: when NGOs lack visibility, stakeholders do not view them as credible, forcing them to rely on high-profile campaigns during annual shareholder meetings. However, these actions generate attention but rarely influence decisions. As NGOs gain recognition, they can campaign earlier, when votes are still open, and meaningfully sway shareholders and change corporate behavior.
