In this paper we develop and estimate a new-Keynesian model of inflation and use it to investigate the hypothesis that prices in the UK are re-set more frequently during periods of high inflation. In the model, firms are assumed to condition their expectations on an optimally-selected but...

We show that the New-Keynesian (NK) model of inflation can be interpreted as a forward-looking cointegrated model. This allows us to model firms' expectations about marginal costs in a simple VAR framework and develop relatively simple formal tests of the model which bypass the econometric...

We use microeconomic data to explore the effects of a changing age-structure on the UK's aggregate personal savings rate. Our findings suggest that changes to the population's age structure age have had detectable, sustained, but, relative to the yearly changes observed in the savings rate over...
