zero sum game

zero sum game


"Zero-sum" describes a situation in which a one person's gain is exactly balanced by losses of the other participant(s).This situation exists whenevery the total amount of resources to be won is fixed. For example:
  • votes in an election.
  • global supplies of fresh water
  • chips in a poker game
  • customers in a mature market for a product like cola.
  • Cutting a birthday cake.
  • distributing tax revenues

These are all situations where cooperation between competitors is unlikely, and the competition can get nasty in a way that is mutually destructive.

A non-zero sum game is a situations where participants can all gain or suffer together, such as a country with an excess of bananas trading with another country for their excess of apples, where both benefit from the transaction.
