The two main types are cooperative games and non-cooperative games.

A public goods game is a game where players decide how much to contribute to a common resource, balancing individual costs against collective benefits.

A saddle point is a situation in a zero-sum game where the strategy is optimal for both players, representing a Nash Equilibrium.

What is the significance of the 'folk theorem' in game theory?

The folk theorem states that in repeated games, a wide range of outcomes can be sustained as equilibria, provided players are sufficiently patient.

A perfect information game is one where all players know the moves previously made by all other players.

A best response function describes the optimal strategy for a player, given the strategies of other players.

Evolutionary game theory studies strategic interactions in populations where strategies evolve over time based on their success.

What is a Bayesian game?

A Bayesian game is a game in which players have incomplete information about other players, often modeled with beliefs represented by probability distributions.

What is 'moral hazard'?

Moral hazard is a situation where one party takes risks because they do not bear the full consequences of their actions.

A common-pool resource problem arises when individuals overuse a shared resource, leading to depletion and negative outcomes for all.

A focal point is a solution that players tend to choose in the absence of communication, often due to its prominence or naturalness.

What is the difference between static and dynamic games?

Static games are played in a single stage, while dynamic games involve multiple stages and may include time-dependent strategies.

What is the concept of 'best response'?

A best response is a strategy that produces the most favorable outcome for a player, given the strategies chosen by other players.

What is 'bounded rationality'?

Bounded rationality is the concept that decision-makers are limited in their ability to process information and make optimal choices.

What is 'extensive form' representation of a game?

Extensive form representation is a way to depict a game using a tree structure that shows the sequential moves of players.

What is 'risk dominance'?

Risk dominance refers to a situation where one strategy is preferred over another due to lower risk of loss, even if it may not be the best response.

What is backward induction?

Backward induction is a method used to solve finite games by analyzing the game from the end to the beginning.

What is a subgame perfect equilibrium?

A subgame perfect equilibrium is a refinement of Nash Equilibrium that requires players' strategies to be optimal in every subgame.

What is a coalition in game theory?

A coalition is a group of players who coordinate their strategies to achieve a better outcome than they would individually.

What is 'normal form' representation of a game?

Normal form representation is a way to represent a game using a matrix that shows the payoffs for each combination of strategies.

What is a commitment in game theory?

A commitment is a strategy where a player makes a binding decision that influences the actions of others.

What is a strictly dominated strategy?

A strictly dominated strategy is one that results in a worse payoff than another strategy, regardless of what the other players do.

What is a strategy profile?

A strategy profile is a combination of strategies chosen by all players in a game.

What is a Nash Equilibrium?

A Nash Equilibrium is a situation in a game where no player can benefit by changing their strategy while the other players keep theirs unchanged.
