This article introduces and analyzes policy-specific factors that help to explain horizontal cooperation among subnational-governments. It thereby builds on but specifies arguments from the literature on horizontal federalism that has usually been focusing on general institutional and societal factors to explain cooperation. These factors capture how a given policy problem unfolds (problem pressure), the ways in which subnational governments are exposed to and experience its consequences in similar or unequal ways (functional interdependencies and their symmetry), and how the issues are treated domestically (problem awareness). We illustrate the potential importance of these factors by analyzing treaties among Swiss substates in the water domain and relying on network analytic methods. We find that problem awareness and functional interdependencies and their (a)symmetries are important, whereas problem pressure has a mixed influence, depending on the issue area. – Reproduced Publius: The Journal of Federalism INTERNATIONAL COOPERATION AR 0 0 ddc 0 0 392082 IIPA IIPA 2021-08-10 50(4), Fall, 2020: p.645-671 AR125228 2021-08-10 AR
