The paper studies the dynamic nature of optimal solutions under commitment in Barro-Gordon and new-Keynesian models and, finds two interesting parameters - the implied targets and the persistence parameter that governs the adjustment toward the implied targets. The implied targets generally...

This paper shows that optimal policy and consistent policy outcomes require the use of control-theory and game-theory solution techniques. While optimal policy and consistent policy often produce different outcomes even in a one-period model, we analyze consistent policy and its outcome in a...
