Abstract:
The paper draws on the economic theory of alliances to stress the importance of considering both benefits and costs arising from the 0interaction between member states of a military alliance in terms of defence expenditure on equipment. We expand the theory of alliances to incorporate the spills that stem from the obligations of each ally by introducing the notion of spill-outs and net spills, the latter measured as the difference between spill-in and spill-out effects. To assess the net spills contribution of each of the members to the alliance, we test for empirical evidence of net spills among a group of North Atlantic Treaty Organization (NATO) allies, applying time-varying Dynamic Quantile Connectedness analysis. The results that stem from our model considering the cost of spill-outs suggest that there are strong incentives among the allies for free-riding behaviour. In line with our theoretical model, our empirical analysis shows that it is only during crisis period that NATO member-states contribute actively to the alliance, something that has become increasingly clear since the recent Russian invasion of Ukraine.

Abstract:
As the international security environment undergoes significant changes, North Atlantic Treaty Organization’s (NATO) capacity to adapt shows how alliances can evolve from focusing on military defence to encompassing a wider spectrum of regional security challenges in an integrated manner. Russia’s violation of international law in 2014, followed by the war in Ukraine, has drawn the attention of NATO to the fact that apart from diplomatic measures, there might be a need to resort to more dynamic means in order to safeguard its members’ interests, especially when the security of the alliance’s eastern flank is threatened. NATO’s evolving role in the international security landscape reflects the alliance’s strategic adaptation to contemporary geopolitical challenges. The 2022 Strategic Concept embodies this change, emphasising NATO’s primary purpose of ensuring collective defence through a comprehensive approach focused on deterrence and defence, crisis prevention and management, and cooperative security (Calmels, 2020; North Atlantic Treaty Organization [NATO], 2022). This change occurs within a complex geopolitical context, further complicated by evolving public opinion. For example, recent trends in the United States, particularly among younger Republican congressional representatives, reveal evolving attitudes towards the support for Ukraine. With growing disapproval of President Biden’s management of the Ukraine crisis, and varying opinions on the level and duration of support for Ukraine, it is evident that public sentiment is divided and evolving (Cerda, 2023; Langer, 2023). These findings reveal the complexity of the US involvement in the Russia–Ukraine conflict and the need for policymakers to consider these diverse viewpoints when shaping the future foreign policy decisions. The shifts in public opinion can also have significant implications for the ongoing conflict (Fisher, 2020), which is expected to continue for an extended period. This dynamic international security situation and shift in public opinion have set the stage for the ongoing challenges that NATO member states face in addressing the war in Ukraine. Consequently, there has been a significant surge in literature exploring these issues, examining them in terms of geopolitics, economics, and even psychology. Thoroughly investigating complex conflicts, such as the war in Ukraine, requires an integrative research approach, drawing on multiple research sources, including scholarly journal articles, government information resources from multiple democratic countries and international organisations, datasets, public policy research institute materials, multiple social media platforms, and public opinion polls. Researchers must navigate the strengths and weaknesses inherent in these resources while adopting an interdisciplinary methodology to comprehensively analyse these events.

Abstract:
This paper proposes a method for assessing the cost of friction between North Atlantic Treaty Organisation (NATO) allies and highlights internal threats. This is applied to the Greek–Turkish conflict within the NATO context and concerns the functioning of defence expenditure in Greece, modified in such a way as to focus on the causes of friction between these allies. The analysis concentrates mainly on the issue of internal threats to the long-run equilibrium of NATO. The ARDL methodology used modifies the typical error correction model by introducing a mechanism that accelerates the process that leads back to the long-run equilibrium. Along with assessing the cost to an ally in relation to an internal threat, the method proposed allows the time required for the long-run equilibrium of NATO to be restored. The paper concludes that dynamic incidents of friction between allies expressed as an internal threat disturb NATO’s static equilibrium, destabilise an individual ally’s defence policy and contribute to cost being incurred.
