Reputation Effects with Imperfect Monitoring in Linear Quadratic Models

The author solves for the reputational equilibrium in a class of linear quadratic Gaussian dynamic games with noisy control. This equilibrium is particularly simple to describe and tractable. There is imperfect monitoring but a sequential equilibrium is found where the uninformed agents always smoothly learn the type of the informed agent. Reputation effects are temporary in the infinite horizon case for positive discount rates; as the discount factor tends to unity there is a permanent reputation.
