On uniqueness of equilibrium in the Kyle model

McLennan, Andrew; Monteiro, Paulo Klinger; Tourky, Rabee


A longstanding unresolved question is whether the one-period Kyle model of an informed trader and a noisily informed market maker has an equilibrium that is different from the closed-form solution derived by Kyle (Econometrica 53:1315–1335, 1985). This note advances what is known about this open problem.
