Many water allocation agreements in transboundary river basins are inherently unstable. Due to stochastic river flow, agreements may be broken in case of drought. The objective of this paper is to analyze whether water allocation agreements can be self-enforcing, or sustainable. We do so using...

We survey the economics of transboundary river water allocation, which emerged in the 1960s and has matured over the last decade due to increasing concerns over water scarcity and pollution. We outline the major approaches and pay specific attention to the strategic aspects of transboundary...

Motivated by recent examples of collective effort on the war on terror, we examine the incentives that retaliation may produce for the endogenous formation of an international counterterror coalition. We show that there are quite reasonable circumstances under which any nation that is a target...

Civil wars are intricate social, political and psychological phenomena. However, economics can offer analytical insights which are useful alongside the more conventional approach of case-studies. Indeed, the policy conclusions drawn from economic analysis sometimes cast doubt on conventional...

This paper develops a model of conflict resolution over scarce water in a trans-boundary river. In our model, we consider countries that are located along a river and made a military investment. Given these investments and their location along the river, they sequentially bargain over the...

We model a rent-seeking contest among two "identity ideologues", differentially located along a uni-dimensional identity continuum, and a "mercenary", who can choose any location in-between. The contest jointly awards an identity-relevant good ("religion") and an identity-irrelevant good...

Increasing concerns about climate change have given rise to the formation of International Environmental Agreements (IEAs) as a possible solution to limit global pollution effects. In this paper, we study the stability of IEAs in a repeated game framework where we restrict to strategies which...

What is the strategic role of membership in an intergovernmental group with unanimity requirements if the group negotiates with an external player in a setting with incomplete information? Being in such a group has a strategic effect compared to negotiating as a standalone player and reduces the...

I explore possible impacts of reciprocal preferences on participation in international environmental agreements. Reciprocal countries condition their willingness to abate on others' abatement. No participation is always stable. A full or majority coalition can be stable, provided that...
