Summary	The bargaining model of war, given its canonical statement by James Fearon in 'Rationalist Explanations for War' (1995), treats war not as the failure of reason but as a failure of bargaining. Because fighting is costly and uncertain, there almost always exists a peaceful division of the disputed stakes that both rational states would prefer to the gamble of war. The puzzle, and the model's central contribution, is to identify the specific conditions — private information with incentives to misrepresent, commitment problems, and issue indivisibility — under which rational, unitary states nonetheless fail to reach such a settlement.	A crisis bargaining game is a formal, usually extensive-form model in which two states sequentially choose to challenge, escalate, stand firm, or back down during an international dispute, and the analyst solves for the equilibrium pattern of escalation and concession. Building on Schelling's strategy of conflict and given an influential treatment in Fearon's (1994) model of escalation as a war of attrition, these games make explicit how incomplete information about each side's resolve, and the costs each pays for backing down, shape whether a crisis ends in mutual accommodation, capitulation, or war.
