Yanis Varoufakis, finance minister of Greece and a former econ professor specializing in game theory, has a great op-ed on why his field provides a very poor basis for his actions: No Time for Games in Europe:
Game theorists analyze negotiations as if they were split-a-pie games involving selfish players. Because I spent many years during my previous life as an academic researching game theory, some commentators rushed to presume that as Greece’s new finance minister I was busily devising bluffs, stratagems and outside options, struggling to improve upon a weak hand.
Nothing could be further from the truth.
If anything, my game-theory background convinced me that it would be pure folly to think of the current deliberations between Greece and our partners as a bargaining game to be won or lost via bluffs and tactical subterfuge.
The trouble with game theory, as I used to tell my students, is that it takes for granted the players’ motives. In poker or blackjack this assumption is unproblematic. But in the current deliberations between our European partners and Greece’s new government, the whole point is to forge new motives. To fashion a fresh mind-set that transcends national divides, dissolves the creditor-debtor distinction in favor of a pan-European perspective, and places the common European good above petty politics, dogma that proves toxic if universalized, and an us-versus-them mind-set.
