My monograph entitled "Interorganizational Diffusion in International Relations: Regional Institutions and the Role of the European Union" will be published by Oxford University Press in May.
How and under what conditions does the European Union (EU) shape processes of institution building in other regional organizations? Interorganizational Diffusion in International Relations: Regional Institutions and the Role of the European Union develops and tests a theory of interorganizational diffusion in international relations that explains how successful pioneer organizations shape institutional choices in other organizations by affecting the institutional preferences and bargaining strategies of national governments. The author argues that Europe's foremost regional organization systematically affects institution building abroad, but that such influence varies across different types of organizations. Mixing quantitative and qualitative methods, it shows how the EU institutionally strengthens regional organizations through active engagement and by building its own institutions at home. Yet, the contractual nature of other regional organizations bounds this causal influence; EU influence makes a distinguishable difference primarily in those organizations that, like the EU itself, rest on an open-ended contract. Evidence for these claims is drawn from the statistical analysis of a dataset on the institutionalization of 35 regional organizations in the period from 1950 to 2017 as well as detailed single and comparative case studies on institutional creation and change in the Southern African Development Community, Mercosur, the Association of Southeast Asian Nations, and the North American Free Trade Agreement.
