Bill Gates Could Gain a
Lot From a Little Game Theory

John Von Neumann, who made fundamental contributions to computer science and quantum theory, called game theory a mathematical analysis for modeling competition and cooperation in living things, from simple organisms to human beings. Game theory has become useful in helping scientists determine how entities cooperate and compete and which strategies are most successful.
Particularly instructive is Robert Axelrod's The Evolution of Cooperation. The book describes computer games with participants from around the world, focused on determining how individuals in groups, who are likely to interact with others, act in a competitive situation.
His model for competition is the game theory situation called the prisoner's dilemma. Here, individuals pursue selfinterest without a central authority to force cooperation. Each player can choose only to reciprocate or not. Each must choose without knowing what the other will do. If one reciprocates and the other does not, the nonreciprocator comes out ahead initially, but only if the other plays by the rules. If neither reciprocates, both do worse. And in groups, reciprocators always did better in the long run than nonreciprocators. When everyone reciprocated, everyone benefited, not equally, but better than before.
Adhering to both sides of that misunderstood Biblical dictuman eye for an eye, etc.seems the successful strategy, both for the individual and all the members of a group. On the other hand, a hardnosed, tough, nevergiveasuckeranevenbreak attitude, while successful in the short term, is a losing proposition. Scientists have used game theory to understand how small singlecell organisms, morecomplex organisms, animals and humans survive and thrive and the results are the same: only the fittest survive. But the fittest are not the toughest, the biggest or the meanest; they are the fairest and most even handed in their dealings with one another.
If game theory's titfortat seems to succeed in virtually every other place in nature, why not in the free market?
