Game Theory has nothing to do with games for entertainment such as Cards or video games. You therefore always need at least two parties (players) – whether they are competitors, politicians or countries – in order to call it a game. Accessed April 15, 2020.

Before players move in a game, they are either perfectly informed about the ‘history’ of the game or not. A game however is also considered simultaneous when players choose their actions in isolation and have no information on what other players have done or will do. (2006). In order to understand Game Theory better, it is important to be familiar with some of the basic concepts, key terminology and background assumptions. Swaps, forwards, options and other financial instruments are often described as "zero-sum" instruments, taking their roots from a concept that now seems distant. However, most of the times games exist in situations in which individual actions are not observable nor enforceable by an external independent third party. THE place that brings real life business, management and strategy to you. The word ‘game‘ itself for example might already cause some confusion. First of all, it is important that players think carefully before they act. Norton. The important element is if both confess, they receive a longer sentence than if neither suspect said anything. Game Theory is a powerful tool for predicting outcomes of a group of interacting firms where an action of a single firm directly affects the payoff of other participating players. Games in which predetermined joint-action agreements are enforceable are called cooperative games. Given that the suspect in the other room’s best option is to confess, the suspect logically confesses. It is therefore distinguished from individual decision-making situations by the presence of significant interactions with other ‘players’ in the game. Players therefore have to move without knowledge of what their rivals have chosen to do. Some players possess private information, a fact that the others should take into account when forming expectations about how those players will behave. In business for example: will competitors raise prices or lower them? The Nobel Prize. Or in other words: if each player has chosen a strategy and none of the players can benefit by changing strategies while the other players keep theirs unchanged, then the current set of strategic choices and the corresponding payoffs constitutes a Nash Equilibrium. You can for example see this in Chess or football. In addition, Game Theory goes beyond gambling games or even sports. Essentially, any quantifiable gains by one party are equal to the losses of another party. Game theory is a framework for modeling scenarios in which conflicts of interest exist among the players. Each suspect is offered a reduced sentence if he confesses and gives up the other suspect. With simultaneous games, the player has a trickier task of figuring out what the opponents is likely going to do right now.

Bernie Madoff is an American financier who ran a multibillion-dollar Ponzi scheme that is considered the largest financial fraud of all time. The prisoner’s dilemma is a noncooperative game since the suspects cannot convey their intentions to each other.. Samuelson, L. (2016). Most games however are imperfect-information games. During a game, players have multiple actions to choose from. In the real world, we most often encounter games of incomplete information, since people usually tend to keep some crucial information about them to themselves. These kind of games are called zero-sum games. In the world of business, competition between two companies can be analyzed as a game in which the participants play to achieve a long-term competitive edge, maybe even total domination – monopoly. An assumption in Game Theory is that all players in the game are considered ‘rational’ beings. Despite it being in the common interest to cooperate with competitors, following a logical thought process causes the firms to default.
