Abstract
For binary-action supermodular games with a continuum of symmetric players, we show that simple global game information structures can be used to implement an optimal outcome under adversarial equilibrium selection. Journal of Economic Literature Classification Numbers: C72, D82.
Key Words: Information design, supermodular game, smallest equilibrium implementation, global game, potential game.
