Under a conventional policy rule, a central bank adjusts its policy rate linearly according to the gap between inflation and its target, and the gap between output and its potential. Under 'the opportunistic approach to disinflation' a central bank controls inflation aggressively when inflation...

This paper studies optimal discretionary monetary policy in the presence of uncertainty about the degree of financial frictions. Changes in the degree of financial frictions are modelled as changes in parameters of a hybrid New-Keynesian model calibrated for the UK, following Bean, Larsen and...

The inflation targeting policy, which is adopted in a lot of countries in recent years, has been introduced with a band target in most countries. However, in the many theoretical analysis, the target of the inflation rate is assumed to be a point, and the studies that have treated the following...

The subprime crisis produced bizarre movements in real and financial aggregates. In particular, the presence of an unusual relationship between quantitative easing policies and credit market conditions led to an unprecedented drop in the real economic activity. In a Brainard (1967)'s parameter...

It is widely argued that Europe's unified monetary policy calls for the international coordination at the fiscal level. We survey the issues involved with such coordination of fiscal policy as a demand management tool and we use a simple model to investigate the circumstances under which...

During and after the Great Recession of 2008-09, conventional monetary policy in the United States and many other advanced economies was constrained by the effective lower bound (ELB) on nominal interest rates. Several central banks implemented large-scale asset purchase (LSAP) programs, more...

Under a conventional policy rule, a central bank adjusts its policy rate linearly according to the gap between inflation and its target, and the gap between output and its potential. Under the opportunistic approach to disinflation a central bank controls inflation aggressively when inflation is...

We analyse the stability of countries within a monetary union in the face of asymmetric shocks, using a simple but widely applicable model. We show that members of the union may be subject to severe cycles following asymmetric shocks if there is a significant backward looking element in...

In this paper we derive optimal monetary targeting rules under various assumptions about fiscal behavior. In contrast to the existing literature we use a linear-quadratic approach and allow for dynamic games between the two policy authorities. It is shown that optimal monetary behavior is...
