The paper introduces a welfarist approach to the national safety of a nation with membership in a defense alliance as an option. The members are risk averse but heterogeneous in their safety classification. There are two public goods as insurance devices, the domestic military budget and the...

We investigate the role of networks of military alliances in preventing or encouraging wars between groups of countries. A country is vulnerable to attack if there is some fully-allied group of countries that can defeat that country and its (remaining) allies based on a function of their...

Collective contests are examined permitting heterogeneity of stakes within every competing group. Our first concern is whether unequal distribution of stakes in a group can enhance its win probability. Our second concern is whether a large stake in a group can be individually disadvantageous. We...

Victorious alliances often fight about the spoils of war. This paper presents an experiment on the determinants of whether alliances break up and fight internally after having defeated a joint enemy. First, if peaceful sharing yields an asymmetric rent distribution, this increases the likelihood...

The effectiveness of NATO conditionality for institutional reforms is highly controversial. Some papers argue that any effect this conditionality might have had may be due to endogeneity effects, i.e. NATO may have picked the winners. We argue that this is not the case. First, NATO-Mazedonia...

Victorious alliances often fight about the spoils of war. We consider experimentally when members of victorious alliances accept a peaceful division of the spoils, and when they fight against each other, and how the inability to commit to a peaceful division affects their effort contributions in...

This paper surveys some of the strategic aspects that emerge if players fight in an alliance against an enemy. The survey includes the free-rider problem and the hold-up problem that emerges in the baseline model, the role of supermodularity in alliance members' effort contributions, the role of...

Im Verlauf der letzten Dekade konnten die IBSA-Staaten (Indien, Brasilien, Südafrika) ihre Position in der sich verschiebenden Weltordnung erheblich verbessern; das gilt insbesondere für ihren Einfluss auf globale Handelsfragen. Lässt sich ein ähnlicher Aufstieg der IBSAStaaten in der...

NATO agreed its new Strategic Concept at the Lisbon Summit in November 2010. The new Strategic Concept is analyzed in a DIIS Report edited by Jens Ringsmose and Sten Rynning. The report entitled NATO's New Strategic Concept: A Comprehensive Assessment contains 15 individual chapters all on...

We study the role of information exchange through alliances in a framework with contestants who have binding budget limits and know their own budget limit but are incompletely informed about other contestants' budget limits. First, we solve for the Bayesian Nash equilibrium. Then we consider the...

The popular perception of the role of NATO was famously defined by NATO's first Secretary General, Lord Ismay, as "keeping the Russians out, the Americans in and the Germans down". NATO's role is still essentially to keep its members safe from threats, to ensure the cohesion of the transatlantic...

This paper analyses the transformative power of NATO accession that gains in importance due to the enlargement fatigue of the EU, the EU’s rather weak neighbourhood incentives and the increasing importance of regional security as an incentive for compliance with the institutional standards of...

At the Riga Summit in November 2006, NATO (North Atlantic Treaty Organization) declared the NATO Response Force (NRF) a fully operational capability. Yet only 8 months later - and behind closed doors - the Alliance's military authorities rescinded the declaration as it became increasingly clear...

In experiments, people behave more cooperatively when they are aware of an external threat, while in the field, we observe surprisingly high levels of cooperation and altruism within groups in conflict situations such as civil wars. We provide an explanation for these phenomena. We introduce a...

In order for NATO to remain credible and efficient, its new Strategic Concept must address and find solutions to fundamental issues which are likely to define the Alliance’s missions over the next decade, of which the most important ones concern member states’ ability to ensure and reinforce...

This DIIS Report provides an overview of the political and military issues that are likely to shape the coming discussions about NATO's new Strategic Concept. NATO's current Strategic Concept dates back to 1999 and over the last couple years an increasing number of policy-makers have suggested...

This paper quantifies the impact of incentives related to potential membership on institutional change as measured by the World Bank Governance Indicators (WBGI). Based on a panel of 25 transition countries for the period from 1996 to 2008 we show that pre-accession incentives provided by EU and...

I study a two-period model of conflict with two combatants and a third party who is an ally of one of the combatants. The third party is fully informed about the type of her ally but not about the type of her ally's enemy. There is a signaling game between the third party and her ally's enemy...

"This paper reviews the economics approach to conflict and national borders. The paper provides a summary of ideas and concepts from the economics literature on the size of nations; illustrates them within an analytical framework where populations engage in conflict over borders and resources,...

This paper analyses potential internal and external determinants of institutional change as measured by the World Bank Governance Indicators (WBGI) based on a panel of 25 transition countries for the period from 1996 to 2005. We show that natural resources and capital inflows exert an...

"This paper investigates the extent to which strategic objectives of the U.S. government influenced news coverage during the Cold War. We establish two relationships: 1) strategic objectives of the U.S. government cause the State Department to under-report human rights violations of strategic...
