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 uses a time-varying Factor Augmented VAR to investigate the evolving transmission of monetary policy and demand shocks in the UK. Simultaneous estimation of time-varying impulse responses of a large set of macroeconomic variables and disaggregated prices suggest that the response of...

We study alternative approaches to the withdrawal of prolonged unconventional monetary stimulus ("exit strategies") by central banks in large, advanced economies. We first show empirically that large-scale asset purchases affect the exchange rate and domestic and foreign term premiums more...

We show the importance of a dynamic aggregation bias in accounting for the PPP puzzle. We prove that established time-series and panel methods substantially exaggerate the persistence of real exchange rates because of heterogeneity in the dynamics of disaggregated relative prices. When...

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...
