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...

We demonstrate the existence of multiple discretionary equilibria in a mainstream New Keynesian model with capital accumulation. There can be two monetary policy regimes, both of which satisfy conditions of optimality and time consistency. In a response to a cost-push shock one of the regimes...

We develop the approach of Gokhale, Kotlikoff amp; Sabelhaus (1996), based on the lifecycle model of savings, to decompose the differences in the national saving rates between the UK, US and Italy. Our work suggests that the US saving rate is lower principally because Americans on average retire...

This paper investigates the importance of fiscal policy in providing macroeconomic stabilisation in a monetary union. We use a microfounded New Keynesian model of a monetary union which incorporates persistence in inflation and non-Ricardian consumers, and derive optimal simple rules for fiscal...

This paper studies the interactions of fiscal policy and monetary policy when they stabilize a single economy against shocks in a dynamic setting. If both policy-makers are benevolent, then, in our model, the best outcome is achieved when monetary policy does nearly all of the stabilization. If...

We estimate a New Keynesian DSGE model for the Euro area under alternative descriptions of monetary policy (discretion, commitment or a simple rule) after allowing for Markov switching in policy-maker preferences and shock volatilities. This reveals that there have been several changes in...

Using a small-scale microfounded DSGE model with Markov switching in shock variances and policy parameters, we show that the data-preferred description of US monetary policy is a time consistent targeting rule with a marked increase in conservatism after the 1970s. However, the Fed lost its...

We study a Markov-perfect monetary policy in an open New Keynesian economy with incomplete financial markets. We analyze inflation and exchange rate targeting regimes and demonstrate that both cases may result in multiple equilibria. These equilibria feature qualitatively and quantitatively...

The fiscal policy environment central banks operate in can be radically different with respect to debt levels, maturity structures and whether or not fiscal adjustments are spending or tax based. Despite this, most analyses of monetary policy delegation schemes typically ignore the behavior of...

We examine the impact of different degrees of fiscal feedback on debt in an economy with nominal rigidities where monetary policy is determined optimally, rather than following a simple rule. We look at the extent to which different degrees of fiscal feedback enhances or detracts from the...
