We study the effects of fiscal policy rules on the determinacy of rational expectations equilibrium in a perfectly competitive monetary model with constant returns. Government spending implies a distortion of the monetary steady state due to the implied taxation. We show that policy rules that...

We study the effects of stylized fiscal policy rules on the (global) determinacy of rational expectations equilibrium in perfectly competitive monetary model with constant returns to scale and labor as the unique input. Government spending on transfers and/or demand implies a distortion of the...

We show that a so-called expectations-based optimal monetary policy rule has desirable properties in a standard New Keynesian model augmented with a cost channel and inflation rate expectations that are partly backward-looking. In particular, optimal monetary policy under commitment is...

In this paper we present a method for using rational expectations in a linear-quadratic optimizationframework. Following the approach put forward by Sims, we solve the model through a QZdecomposition, which is generally easier to implement than the more widely used method of Blanchardand Kahn.

The paper reviews an algorithm for the iterative solution of rational expectations models. It shows in detail how general equilibrium models with perfect foresight and intertemporally optimizing behavior must be set up to be solved numerically with the algorithm. Three examples of intertemporal...
