Research summary: We examine the variety of activist groups and their tactics in demanding firms' social change. While extant work does not usually distinguish among activist types or their variety of tactics, we show that different activists (e.g., social movement organizations vs. religious groups and activist investors) rely on dissimilar tactics (e.g., boycotts and protests versus lawsuits and proxy votes). Further, we show how protests and boycotts drag companies “through the mud” with media attention, whereas lawsuits and proxy votes receive relatively little media attention yet may foster investor risk perceptions. This research presents a multifaceted view of activists and their tactics and suggests that this approach in examining activists and their tactics can extend what we know about how and why firms are targeted. Managerial summary: The purpose of this study was to examine how different types of activist groups behave differently when targeting firms for social change. We find that traditional activist groups rely on boycotts and protests, whereas religious groups and activist investors rely more on lawsuits and proxy votes. Additionally, we find that protests and boycotts are associated with greater media attention, whereas lawsuits and proxy votes are associated with investor perceptions of risk.
