In macroeconomic models, the level of price dispersion - which is typically approximated through its relationship with inflation - is a central determinant of welfare, the cost of business cycles, the optimal rate of inflation, and the tradeoff between inflation and output stability. While the...

In this paper, we examine the extent to which monetary policy should respond to movements in sectoral inflation rates. To do this we construct a Generalised Taylor model that takes specific account of the sectoral make-up of the consumer price index (CPI). We calibrate the model for each sector...

In this paper we model monthly UK inflation and find that there is some small but significant autocorrelation, particularly at 12 months. We find that this autocorrelation in monthly inflation leads to significant persistence in the headline annual inflation figure. A one-off shock to monthly...

This paper adopts the Impulse-Response methodology to understand inflation persistence. It has often been argued that existing models of pricing fail to explain the persistence that we observe. We adopt a common general framework which allows for an explicit modelling of the distribution of...

Recent studies document the deteriorating performance of forecasting models during the Great Moderation, which conversely implies that forecastability was higher in the preceding era when the economy was unexpectedly volatile. We explain this phenomenon in the context of equilibrium...

The lumpy nature of plant-level investment is generally not taken into account in the context of monetary theory (see, e.g., Christiano et al. 2005 and Woodford 2005). We formulate a generalized (S,s) pricing and investment model which is empirically more plausible along that dimension....

Price setting in German metal-working industries is analysed using a monthly panel of individual price data for more than 2,000 plants covering the period from 1980 to 2001. Motivated by several models in the literature, a duration model is estimated. Price changes can be explained by a...
