Some Experimental Results for a Quantal Response Bargaining Model of War

We provide the first experimental results on a two-stage model of militarized conflict based on the ubiquitous ultimatum bargaining game that dominates much of the theoretical analysis of international relations. We illustrate how data from experimental trials deviate from the equilibrium predictions from both a complete information version of the model and the quantal response version of the model. We discuss how the results from the experiments can inform future theoretical, empirical, and experimental work on bargaining theories of war
