In game theory, coordination games refer to a type of strategic interaction where players can achieve a higher payoff by coordinating their actions. These games typically involve multiple players who must choose between different strategies, and the outcome depends on the players' ability to coordinate their choices.
In coordination games, players have a common interest in achieving a particular outcome, but they face a challenge in aligning their actions due to the lack of communication or trust. The key feature of these games is that there are multiple Nash equilibria, which are sets of strategies where no player has an incentive to unilaterally deviate from their chosen strategy.
One classic example of a coordination game is the "Battle of the Sexes" game. In this game, a couple must decide between going to a football match or a ballet performance. Both partners prefer to be together rather than being alone, but they have different preferences for the event. If they both choose the same event, they receive a higher payoff than if they choose different events. However, if they cannot coordinate their choices, they may end up going to different events and receive a lower payoff.
To solve coordination games, players often rely on focal points, which are salient or easily recognizable strategies that help coordinate their actions. Focal points can be based on social norms, cultural conventions, or shared expectations. In the "Battle of the Sexes" game, for example, the focal point could be the event that is traditionally associated with their gender roles.
Overall, coordination games highlight the importance of communication, trust, and shared expectations in achieving mutually beneficial outcomes. They provide insights into how individuals or groups can coordinate their actions in situations where there is a lack of formal agreements or explicit coordination mechanisms.
