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...

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...

Simple intertemporal consumption theory implies that non-durable consumption is a random walk, but that consumption cointegrates with income and wealth. By the Granger representation theorem, there must be a (vector) error correction mechanism ((V)ECM) representation of the data; but from the...

This Handbook is about useful numerical methods for models commonly used in central banks. The linear general equilibrium model with rational expectations is a natural part of the central bank economist's toolkit. The appropriate modelling of monetary policy in these models is even more so. This...

The methodology used in papers by Darby and Ireland and Caporale and Williams is examined, to see whether it continues to explain UK consumption behaviour. First, Muellbauer and Murphy's proxy for financial liberalisation (FLIB) is updated. Then a forward-looking consumption model is...

This paper examines the sensitivity of the level of consumption to interest rates in a standard partial equilibrium theoretical framework with no uncertainty. Using a multi-period framework, the consumption function is derived and interest rate effects are decomposed into substitution, income...

The implications for consumption and saving behaviour are explored, when households are allowed to borrow, but face penalties which increase with the amount borrowed. It is shown that the introduction of this type of constraints (soft liquidity constraints) does not lead to consumers behaving...
