States, interstitial organizations and the prospects for liberal international order

Abstract

\n This article proposes a complementary approach to analysing destabilization of the liberal international order (LIO) and argues that such challenges are related to endogenous institutional processes within the LIO. Faced with constraints of the core norms, rules and institutions of the LIO, states use interstitial organizations (INTOs)—new organizational forms recombining resources, rules, practices and structures from multiple institutional domains—allowing for innovative ways of delivering foreign policies. Using organization theory and new institutionalist approaches, the article outlines a three-dimensional analytical framework to the study of emergence of interstitial organizational forms and interstitial institutional change of international institutions. It applies this framework to the study of two types of INTOs—the European External Action Service (EEAS) and private military companies (PMCs)—both of which are shown to have transformational impacts on two core primary institutions of the modern state order, namely diplomacy and war. The article argues that reliance on INTOs can both enhance and constrain states ability to promote the core principles of the LIO and concludes with a discussion of two possible paths of adaptation of this order.
