Though I have heard of game theory being used in a few particular and special cases (e.g. the auctioning of 3G cellphone licenses) I have not seen anything of it being used in general strategic management or business planning. The strategy textbooks dismiss it as too uni-dimensional and limited to special cases to be useful, and I can find virtually no articles in e.g. Harvard Business Review or McKinsey Quarterly giving any encouraging cases where it has been helpful. (Though I did see on 12manage reference to a strategy+business article on Barry Nalebuff).
Does anyone know otherwise?
