In his book The War Trap Bruce Bueno de Mesquita claims to offer a deductive theory of international conflict based on the assumption that foreign policy makers attempt to maximize their expected utility. The theory is subjected to a systematic empirical test that seems to provide impressive confirmation. The first part of this article examines Bueno de Mesquita's theory and argues that it cannot be derived from his assumptions. The second part examines the operational version of the theory, which was the one actually tested, and argues that it can be more plausibly interpreted as a version of a different theory—one that Bueno de Mesquita claims to have discredited. The essay concludes by discussing the significance of this book with regard to the question of whether theories of individual rational choice can explain foreign policy decisions.

Vilfredo Pareto's contribution to modem economic theory is today universally recognized, but to my mind his particular contribution to utility theory is not sufficiently understood. In the following paragraphs I intend to give an assessment and evaluation of Paretian thought on this important topic. It seems that Pareto' s contribution to utility theory originated as a reaction to the attitude of Walras and the Austrian School of.Economists to this same theory. The latter thought that utility theory, as they understood it, was a sort of ultimate truth, a key to all the secrets of pure economics. Consequently they placed such an emphasis on it that they induced Pareto and the Paretians to do their best to demolish it. Such was their eagerness that some even held that this departure constituted Pareto's main contribution to economic theory. ; N/A
