This paper analyses the major changes in both monetary and fiscal policy that have taken place over the past two decades and, within the limits of the existing empirical research, evaluates the overall costs and benefits for the OECD economies. The general findings for monetary policy are that,...

The presence of a lower bound of zero on nominal interest rates has important implications for the conduct of optimal monetary policy. Standard rational expectations models can have alternative steady states as well as non-unique laws of motion, i.e. there can be possible sunspot equilibria....

This paper explicitly models strategic interaction between two independent national fiscal authorities and a single central bank in a simple New Keynesian model of a monetary union. Monetary policy is constrained by the zero lower bound on nominal interest rates. Coordination of fiscal policies...

We investigate open economy dimensions of optimal monetary and fiscal policy at the zero lower bound (ZLB) in a small open economy model. At positive interest rates, the trade elasticity has negligible effects on optimal policy. In contrast, at the ZLB, the trade elasticity plays a key role in...

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...

How to conduct macro-prudential regulation? How to coordinate monetary policy and macro-prudential policy? To address these questions, I develop a continuous-time New Keynesian economy in which a financial intermediary sector is subject to a leverage constraint. Coordination between monetary and...

This paper develops the theoretical framework and studies discretionary non-cooperative monetary and fiscal policy stabilisation in a New Keynesian model, where the fiscal policymaker uses distortionary taxes as the policy instrument and operates with long periods between optimal adjustments of...

This paper investigates the stabilization bias that arises in a model of monetary and fiscal policy stabilization of the economy, when assuming that the monetary authority put higher weight on inflation stabilization than society. We demonstrate that inflation-conservatism unambiguously leads to...
