Definition§
A zero-sum game is a concept from game theory and economic theory where the total gains and losses among participants equal zero. In other words, one player’s gain is another player’s loss, and the net change in wealth or benefit is zero. This notion is crucial in various strategic interactions, including competitive business practices, trading markets, and certain political situations.
Examples§
- Poker: In a poker game, the total amount of money won by one or more players is equal to the amount lost by others. The net gain and loss are always zero when added up.
- Stock Trading: When one investor profits from buying low and selling high, another may suffer losses by selling low or buying high.
- Contract Negotiations: If one party to a negotiation secures a more favorable contract term, the other party must often concede some advantage, leading to a balanced outcome of gains and losses.
Frequently Asked Questions (FAQs)§
Q: Can a zero-sum game be beneficial for all participants?
A: No, by definition, a zero-sum game results in the gains for some participants being exactly offset by the losses of others. It is not possible for all participants to benefit simultaneously.
Q: How does a zero-sum game differ from a non-zero-sum game?
A: In a zero-sum game, the total amount of benefit is fixed and one participant’s gain is exactly another’s loss. In a non-zero-sum game, the total benefit can increase or decrease, allowing for mutually beneficial or mutually detrimental outcomes.
Q: Are zero-sum games common in real-life scenarios?
A: Zero-sum games are less common in real-life scenarios, as many interactions in economics and business involve situations where all parties can benefit (non-zero-sum).
Related Terms§
- Non-Zero-Sum Game: In contrast to a zero-sum game, a non-zero-sum game allows for the total gains and losses to differ among parties, offering the potential for all participants to be better or worse off.
- Game Theory: A field of study that deals with mathematical models of strategic interaction among rational decision-makers.
- Pareto Efficiency: A state of allocation where resources cannot be reallocated to make one party better off without making another party worse off.
