Our contribution to this symposium speaks to the origins of international organization (IO) reputation. The one explored by Daugirdas is agency slack: when people delegated power and authority within an organization—in her example, UN peacekeepers and their surrounding bureaucracy—abuse their privilege and stain the institution's character. We explore another that can spark similar reactions and consequences, but which emanates from the behavior of the principals themselves (rather than their agents): the member states. The company an IO keeps—how members behave—can bolster or stain the organization's reputation. That in turn can have consequences, especially for organizations seeking to provide a venue for members to make credible commitments.
