This paper uses a factor-augmented vector autoregression technique to examine the role that macroeconomic and sector-specific factors play in UK price fluctuations at the aggregate and disaggregated levels. Macroeconomic factors are less important for disaggregated prices than aggregate ones....

This paper develops a DSGE model in which banks use short-term deposits to provide firms with long-term credit. The demand for long-term credit arises because firms borrow in order to finance their capital stock which they only adjust at infrequent intervals. We show within a real business cycle...

This paper develops a fast method of computing arbitrary order perturbation approximations to bond prices in DSGE models. The procedure is implemented to third order where it can shorten the approximation process by more than 100 times. In a consumption-based endowment model with habits, it is...

This paper investigates the potential implications for sterling of the US current account returning to balance. The analysis is conducted using a three-country model comprising the United Kingdom, the United States and a block that is meant to represent the rest of the world. The main conclusion...

This paper analyses the conduct of monetary policy in an environment in which cyclical swings in risk appetite affect households’ propensity to save. It uses a New Keynesian model featuring external habit formation to show that taking note of precautionary saving motives justifies an...

This paper considers the implications for the United States, the United Kingdom and the rest of the world (ROW) of shocks that may contribute to a further reduction in global current account imbalances using a dynamic stochastic general equilibrium (DSGE) model. We consider a shock that...

Empirical evidence suggests that risk premia are higher at business cycle troughs than they are at peaks. Existing asset pricing theories ascribe moves in risk premia to changes in volatility or risk aversion. Nevertheless, in a simple general equilibrium model, risk premia can be procyclical...

Theory tells us that output, the capital stock and the user cost of capital are related. From the capital accumulation identity, it also follows that the capital stock and investment have a long-run proportional relationship. The dynamic structure thus implies a multi-cointegrating framework, in...

This paper examines the behaviour of individual consumer prices in the United Kingdom, and uncovers a number of stylised facts about pricing behaviour. First, on average 19% of prices change each month, although this falls to 15% if sales are excluded. Second, the probability of price changes is...

This paper examines the behaviour of supermarket prices in the United Kingdom, using weekly scanner data supplied by Nielsen. A number of stylised facts about pricing behaviour are uncovered. First, prices change very frequently in supermarkets, with 40% of prices changing each week, and even...
