Game Harmony: A Short Note

Abstract

Strategic uncertainty in game theory may have two different general sources, either alone or in combination: uncertainty because of the existence of a coordination problem, and uncertainty because of a conflict between one own and the other n players' interests. Game harmony is conceived as a generic game property that describes how harmonious (non-conflictual) or disharmonious (conflictual) the interests of the n players are, as embodied in the game payoffs. Pure coordination games are examples of games with maximal game harmony; zero sum games are examples of games with very low game harmony. This note briefly describes attempts to measure game harmony simply as a real-valued number.
