Pure play method. In finance, the "pure play method" is an approach used to estimate the cost of equity capital of private companies, which involves examining the beta coefficient of other public and single focused companies. [2] See also Hamada's equation . Here, when estimating a private company A's equity beta coefficient, the equity beta ...
A pure strategy provides a complete definition of how a player will play a game. Pure strategy can be thought about as a singular concrete plan subject to the observations they make during the course of the game of play. In particular, it determines the move a player will make for any situation they could face. A player's strategy set is the ...
The first pure play semiconductor company is the Taiwan Semiconductor Manufacturing Corporation, a spin-off of the government Industrial Technology Research Institute, which split its design and fabrication divisions in 1987, a model advocated for by Carver Mead in the U.S., but deemed too costly to pursue.
Nash proved that if mixed strategies (where a player chooses probabilities of using various pure strategies) are allowed, then every game with a finite number of players in which each player can choose from finitely many pure strategies has at least one Nash equilibrium, which might be a pure strategy for each player or might be a probability ...
Gamesmanship. Feigning, exaggerating or drawing out an injury is a common strategy in association football to draw out time and an example of gamesmanship. Gamesmanship is the use of dubious (although not technically illegal) methods to win or gain a serious advantage in a game or sport. It has been described as "Pushing the rules to the limit ...
Coordination game. A coordination game is a type of simultaneous game found in game theory. It describes the situation where a player will earn a higher payoff when they select the same course of action as another player.
In game theory, a subgame perfect equilibrium (or subgame perfect Nash equilibrium) is a refinement of a Nash equilibrium used in dynamic games. A strategy profile is a subgame perfect equilibrium if it represents a Nash equilibrium of every subgame of the original game. Informally, this means that at any point in the game, the players ...
Symmetric game. In game theory, a symmetric game is a game where the payoffs for playing a particular strategy depend only on the other strategies employed, not on who is playing them. If one can change the identities of the players without changing the payoff to the strategies, then a game is symmetric. Symmetry can come in different varieties.
