Time-inconsistency is an essential feature of many policy problems (Kydland and Prescott, 1977). This paper presents and compares three methods for computing Markov-perfect opti- mal policies in stochastic nonlinear business cycle models. The methods considered include value function iteration,...

Recent work on optimal monetary and fiscal policy in New Keynesian models suggests that it is optimal to allow steady-state debt to follow a random walk. Leith and Wren-Lewis (2012) consider the nature of the timeinconsistency involved in such a policy and its implication for discretionary...

We consider optimal monetary and fiscal policies in a New Keynesian model of a small open economy with sticky prices and wages. In this benchmark setting monetary policy is all we need - analytical results demonstrate that variations in government spending should play no role in the...

Recent work on optimal policy in sticky price models suggests that demand management through fiscal policy adds little to optimal monetary policy. We explore this consensus assignment in an economy subject to ‘deep’ habits at the level of individual goods where the counter-cyclicality of...

The potential importance of fiscal policy in influencing inflation has recently been highlighted, following Woodford (1998), under the heading of the ‘Fiscal Theory of the Price Level’ (FTPL). Some authors have suggested that this theory provides a rationale for the Pact for Stability and...

The potential importance of fiscal policy in influencing inflation has recently been highlighted, following Woodford (1995), under the heading of the ‘Fiscal Theory of the Price Level’ (FTPL). Applications of this theory to open economies operating under flexible exchange rates has suggested...

Recent attempts to incorporate optimal fiscal policy into New Keynesian models subject to nominal inertia, have tended to assume that policy makers are benevolent and have access to a commitment technology. A separate literature, on the New Political Economy, has focused on real economies where...

This paper examines the issue of fiscal sustainability in emerging market countries and industrial countries. We highlight the importance of the time series properties of the primary surplus and debt, and find evidence of a positive long run relationship. Consequently we emphasise, that...
