Zero-sum game
A zero-sum game is a situation often cited in game theory, in which an advantage that is won by one of two sides is lost by the other. After the losses and gains, the net effect on both sides is equal to zero. A zero-sum game may have as few as two players or as many as millions of participants. The model of a zero-sum game includes all the resources at the start, meaning the supply of resources is insusceptible to shrinkage, growth or any external intervention. The zero-sum game only allows for the redistribution of the initial amount of resources.A zero-sum game assumes perfect information and perfect competition, where both parties make an informed decision and have all the relevant information.
