In this paper we consider the optimal control problem of models with Markov regime shifts and forward-looking agents. These models are very general and flexible tools for modelling model uncertainty. An algorithm is devised to compute the solution of a linear rational expectations model with...

Household debt and house prices in the United Kingdom rose substantially between 1987 and 2006. In this paper we use a calibrated overlapping generations model of the household sector to examine the extent to which changes in demographics, lower inflation, and a lower long-run real interest rate...

This paper examines the trade-offs that a central bank faces when the exchange rate can experience sustained deviations from fundamentals and occasionally collapse. The economy is modelled as switching randomly between different regimes according to time-invariant transition probabilities. We...

The purpose of this paper is to examine how important an improvement in global monetary policy might be for the macroeconomic performance of a small open economy such as the United Kingdom. Our paper contributes to the literature by proposing a new methodology to treat indeterminate solutions...

We consider finite horizon conditioning paths for nominal interest rates in New Keynesian monetary policy models. This is done two ways. First, we develop a simple way to use policy interventions in the form of interest rate shocks to achieve the conditioning path and show this yields a unique...

A commonly held view is that the life of a monetary policy maker forced to operate under discretion can be improved by the authorities delegating monetary policy objectives that are different from the social welfare function (including interest rate smoothing, price-level targeting and...
