Asymmetric coordination game

A version of Chicken Consider the version of "Chicken" pictured in Figure 6. Like all forms of the game, there are three Nash equilibria. Now consider a third party or some natural event that draws one of three cards labeled:

Stag hunt This is different in another type of coordination game commonly called battle of the sexes or conflicting interest coordinationas seen in Fig.

In this game both players prefer engaging in the same activity over going alone, but their preferences differ over which activity they should engage in. Player 1 prefers that they Asymmetric coordination game party while player 2 prefers that they both stay at home.

Finally, the stag hunt game in Fig. However, cooperation might fail, because each hunter has an alternative which is safer because it does not require cooperation to succeed hunting a hare. This example of the potential conflict between safety and social cooperation is originally due to Jean-Jacques Rousseau.

Voluntary standards[ edit ] In social sciencesa voluntary standard when characterized also as de facto standard is a typical solution to a coordination problem.

In contrast, an obligation standard enforced by law as " de jure standard" is a solution to the prisoner's problem. The pure Nash equilibria are the points in the bottom left and top right corners of the strategy space, while the mixed Nash equilibrium lies in the middle, at the intersection of the dashed lines.

Unlike the pure Nash equilibria, the mixed equilibrium is not an evolutionarily stable strategy ESS. The mixed Nash equilibrium is also Pareto dominated by the two pure Nash equilibria since the players will fail to coordinate with non-zero probabilitya quandary that led Robert Aumann to propose the refinement of a correlated equilibrium.

Nash equilibria shown with points, where the two player's correspondences agree, i.

Learning and coordinating in a multilayer network

Often we are confronted with circumstances where we must solve coordination problems without the ability to communicate with our partner. Many authors have suggested that particular equilibria are focal for one reason or another.

For instance, some equilibria may give higher payoffsbe naturally more salientmay be more fairor may be safer. Sometimes these refinements conflict, which makes certain coordination games especially complicated and interesting e.

Experimental results[ edit ] Coordination games have been studied in laboratory experiments. One such experiment by Bortolotti, Devetag, and Ortmann was a weak-link experiment in which groups of individuals were asked to count and sort coins in an effort to measure the difference between individual and group incentives.

Players in this experiment received a payoff based on their individual performance as well as a bonus that was weighted by the number of errors accumulated by their worst performing team member. Players also had the option to purchase more time, the cost of doing so was subtracted from their payoff.

Even when payoffs are better when players coordinate on one equilibrium, many times people will choose the less risky option where they are guaranteed some payoff and end up at an equilibrium that has sub-optimal payoff.

Players are more likely to fail to coordinate on a riskier option when the difference between taking the risk or the safe option is smaller. The laboratory results suggest that coordination failure is a common phenomenon in the setting of order-statistic games and stag-hunt games.

Conversely, game theorists have modeled behavior under negative externalities where choosing the same action creates a cost rather than a benefit. The generic term for this class of game is anti-coordination game. The best-known example of a 2-player anti-coordination game is the game of Chicken also known as Hawk-Dove game.

This counters the standard coordination game setup, where all unilateral changes in a strategy lead to either mutual gain or mutual loss.In game theory, coordination games are a class of games with multiple pure strategy Nash equilibria in which players choose the same or corresponding strategies.

If this game is a coordination game, then the following inequalities hold in the payoff matrix for player 1 (rows): A > B, D > C, and for player 2 (columns): a > c, d > b. Free, Ready to play, Nothing to install, No need to register!

We present a quantum approach to play asymmetric coordination games, which are more general than symmetric coordination games such as the Battle of the Sexes game, the Chicken game and the HawkDove game.

games with asymmetric payoffs (“asymmetric games”), in the latter case with or without salient decision labels. 3 Although learning may converge to equilibrium over time, we study subjects’ initial responses, which reveal their strategic thinking most clearly.
