CORE DEFINITION

Players decide their strategies by observing a common, third-party public signal (such as a traffic light). This is more efficient than Nash equilibrium because it does not require players to guess what others are thinking; they only need to follow the signal. Scaffold role: The coordinating value of rules. A traffic light itself has no enforcement power, but it provides a 'correlation device' that everyone voluntarily complies with. In management, setting clear public signals (such as countdowns or kanban boards) can significantly reduce communication costs.

Correlated equilibrium: Using public signals to coordinate, so that each party chooses the optimal action according to the signal, achieving an equilibrium that can be superior to Nash.

MINIMUM ACTION

Practice this model in one real situation:

Set a public signal. 2. Respond according to the signal. 3. Achieve coordination.
