This paper investigates the relationship between uncertainty and economic activity in a DSGE model with sticky prices and credit frictions. We analyse the effect of a mean preserving shock to the variance of aggregate total factor productivity (macro uncertainty) and we compare it to the effect...

Are uncertainty shocks a major source of business cycle fluctuations? This paper studies the effect of a mean preserving shock to the variance of aggregate total factor productivity (macro uncertainty) and to the dispersion of entrepreneurs' idiosyncratic productivity (micro uncertainty) in a...

We examine the impact that technology shocks have in a trivariate VAR that includes productivity, hours worked per person and the employment ratio. These last two variables have trends that make them non-stationary. There are three results of interest. First, a technology shock reduces both...

Most New Keynesian models are derived under the assumption that inflation is equal to zero in the steady-state and yet most central banks around the world have inflation targets that are greater than such a number. In this paper we consider the open economy (welfare) implications of non-zero...

This paper introduces the Bank of England's new forecasting platform and provides examples of how it can be applied to practical forecasting problems. The platform consists of four components: COMPASS, a structural central organising model; a suite of models, used to fill in the gaps in the...
