Information Design with Elicitation and Strategic Coordination

Understand

We study linear-quadratic games of incomplete information with Gaussian uncertainty, where each player's payoff depends on a privately observed type and a common state.

• The designer observes the state, elicits types, and sells action recommendations.
• We characterize all implementable mechanisms with Gaussian joint distributions of actions and fundamentals, and identify the players-optimal, consumer-optimal, and revenue-maximizing designs.
• In games of strategic complements (substitutes), these optimal mechanisms maximally correlate (anticorrelate) players' actions.
