We consider optimal monetary stabilization policy in a New Keynesian model with explicit microfoundations, when the central bank recognizes that private-sector expectations need not be precisely model-consistent, and wishes to choose a policy that will be as good as possible in the case of any...

We consider a general class of nonlinear optimal policy problems with forward-looking constraints, and show how to derive a problem with linear constraints and a quadratic objective that approximates the exact problem. The solution to the LQ approximate problem represents a local linear...

While many analyses of monetary policy consider only the adjustment of a central bank's target for a short-term nominal interest rate, other dimensions of policy have recently been of greater importance: changes in the supply of bank reserves beyond those required to achieve an interest-rate...

We consider the effects of central bank purchases of a risky asset as an additional dimension of policy alongside "conventional" interest rate policy in a general-equilibrium model of asset pricing with endogenous collateral constraints. The effects of asset purchases depend on the way that they...

This paper considers a general class of nonlinear rational-expectations models in which policymakers seek to maximize an objective function that may be household expected utility. We show how to derive a target criterion that is 1) consistent with the model’s structural equations, 2) strong...

We extend the basic (representative-household) New Keynesian [NK] model of the monetary transmission mechanism to allow for a spread between the interest rate available to savers and borrowers, that can vary for either exogenous or endogenous reasons. We find that the mere existence of a...
