Corrigendum to “Games With Imperfectly Observable Actions in Continuous Time”
Econometrica · 2010 · Volume 78 · Issue 3
Abstract
Sannikov (2007) investigated properties of perfect public equilibria in continuous-time repeated games. This note points out that the proof of Lemma 6, required for the proof of the main theorem (Theorem 2), contains an error in computing a Hessian matrix. A correct proof of Lemma 6 is provided using an additional innocuous assumption and a generalized version of Lemma 5.
