A type of game wherein one player can gain only at the expense of another player.
A situation where the gain
of one person equates to the loss
of another person. That is, for every dollar one person makes in a zero sum transaction
, another person loses a dollar. Not every transaction is a zero sum game; stock
trading is not because some trades are mutually beneficial to the buyer
and the seller
markets, however, are zero sum games because wealth
cannot be created from these transactions, only shifted. See also: Wealth creation
A situation in which one person's gain must be matched by another person's loss. Without considering taxes and transaction costs, many types of investing, such as options and futures, are examples of zero-sum games.
