In game theory, simultaneous and sequential games are two different types of strategic interactions between players. The main difference between these two types lies in the timing of players' decision-making and the information available to them.
Simultaneous games, also known as static games, are characterized by players making their decisions simultaneously, without knowing the choices made by other players. In this type of game, players choose their strategies independently and simultaneously reveal their choices. The outcomes and payoffs are determined based on the combination of strategies chosen by all players. Examples of simultaneous games include the Prisoner's Dilemma and the Battle of the Sexes.
On the other hand, sequential games involve players making their decisions in a specific order, with each player having knowledge of the previous players' choices. In sequential games, players take turns in making decisions, and the order of play can significantly impact the outcomes. Players can observe the actions of previous players and use this information to strategically plan their own moves. Examples of sequential games include the Ultimatum Game and the Centipede Game.
The distinction between simultaneous and sequential games is crucial as it affects the strategies and outcomes in each type of game. In simultaneous games, players must anticipate the choices of others and consider the best response given the possible actions of their opponents. In sequential games, players have the advantage of observing the actions of previous players, which allows for strategic thinking and the possibility of influencing the decisions of subsequent players.
Furthermore, the concept of information plays a significant role in distinguishing simultaneous and sequential games. In simultaneous games, players lack information about the choices made by others, leading to uncertainty and the need to make decisions based on assumptions or predictions. In contrast, sequential games provide players with more information, allowing them to make decisions based on observed actions and adjust their strategies accordingly.
Overall, the difference between simultaneous and sequential games lies in the timing of decision-making and the information available to players. Simultaneous games involve independent decision-making without knowledge of others' choices, while sequential games involve decision-making in a specific order with players having information about previous choices. Understanding these distinctions is crucial in analyzing and predicting strategic behavior in various economic and social situations.
