# Zero Sum Agreement

Zero games don`t need to get a positive net result – they could also be negative. In the hacker example above, there is a case where hackers win and this is a net negative for the entire system. The battle of the sexes is a simple example of a typical game without zero sum. In this example, a man and his wife want to go out for the evening. They chose to go to either a ballet or a boxing match. The two prefer to walk together rather than go alone. While the man prefers to go to boxing, he prefers to go to ballet with his wife rather than go to fight alone. In the same way, the woman would rather go to ballet, but she too would rather go to battle with her husband than go to ballet alone. The matrix that represents the game is shown below: you`ll have read a lot about zero-sum games lately, because that`s the basis of Trump`s tariffs.

Zero sums are a situation in game theory where one person`s gain corresponds to the loss of another, so that the net change in wealth or utility is zero. A zero-sum game can only have two players or up to millions of participants. In financial markets, options and futures are examples of zero-sum gambling without transaction fees. For every person who receives a contract, there is a quid pro quo that loses. The appropriate pfennige game is often cited as an example of zero-sum play, according to game theory. The game includes two players, A and B, who put a penny on the table at the same time. The payment depends on whether or not the pennies are matched. If both pfennige are heads or dicks, the player wins A and keeps player B`s penny; If they don`t match, Player B wins and keeps Player A`s penny. For final total games with two players, the different game theory solutions offer the same Nash-Balance, Minimax and Maximin solution.

When players are allowed to play a mixed strategy, the game always has a balance. In a zero-sum game, winnings for one person (s) cause identical losses for another person. The net change for all parties involved is zero and no wealth is created or destroyed during the transaction. Although pure-money situations are rare (12, 13), many people perceive zero-sum situations as zero-sum situations because they believe that one person`s profits are offset by another person`s loss (14, 15).
