This chapter introduces a new framework for understanding firm creation and firm behavior in the face of terrorism and its ensuing risks such as institutional disruption. There is surprisingly scant theoretical or empirical research on how terrorism impacts firms and their ability to be agile in the face of risk. The extant strategic management literature is underdeveloped for making such assessments because it largely ignores the socio-cognitive impact of collective traumas on society. Building on the traditional assumptions of institutional theory from strategic management, the authors incorporate cosmopolitan memory theory from the field of international relations to offer a theoretically grounded set of testable predictions about terrorism's effects on both new and existing firms.
