The last few years papers have begun to analyse optimal monetary and fiscal policy in models incorporating nominal rigidities where social welfare is derived from the utility of agents. This paper examines whether this analysis provides support for the consensus assignment, where monetary policy...

In a monetary union where fiscal authorities act strategically fiscal cooperation is unlikely to emerge as an equilibrium. Even when the cooperative outcome is the best for a national fiscal authority, it is either not a Nash equilibrium, or only one of several Nash equilibria. The monetary...

We study discretionary equilibria in dynamic linear-quadratic rational expectations models. In contrast to the assumptions that pervade this literature we show that these models do have multiple equilibria in some situations. We demonstrate the existence of multiple discretionary equilibria by...

Discretionary policymakers cannot manage private-sector expectations and cannot coordinate the actions of future policymakers. As a consequence, expectations traps and coordination failures can occur and multiple equilibria can arise. To utilize the explanatory power of models with multiple...

We study the existence and uniqueness properties of monetary policy with limited commitment in LQ RE models. We use a New Keynesian model with debt accumulation in the spirit of Leeper (1991) as a `lab', because this model generates multiple equilibria under pure discretion, and under full...

In this paper we present two examples where the presence of inflation persistence could influence the qualitative nature of monetary policy. In the first case the desirability of a monetary policy regime comes under question when extensive inflation persistence exists. In the second case the...

We examine the impact of different degrees of fiscal feedback on debt in an economy with nominal rigidities where monetary policy is optimal. We look at the extent to which different degrees of fiscal feedback enhance or detract from the ability of the monetary authorities to stabilize output...

Discretionary policymakers cannot manage private-sector expectations and cannot coordinate the actions of future policymakers. As a consequence, expectations traps and coordination failures can occur and multiple equilibria can arise. To utilize the explanatory power of models with multiple...

This paper studies discretionary non-cooperative monetary and …fiscal policy stabilization in a New Keynesian model, where the …fiscal policymaker uses a distortionary tax as the policy instrument and operates with long periods between optimal time-consistent adjustments of the...

This paper investigates the conduct of monetary and fiscal policy in the post-ERM period in the UK. Using a simple DSGE New Keynesian model of non-cooperative monetary and fiscal policy interactions under fiscal intra-period leadership, we demonstrate that the past policy in the UK is better...
