Intuitively core inflation is understood as a measure of inflation where noisy price movements are avoided. This is typically achieved by either excluding or downplaying the importance of the most volatile items. However, some of those items show high persistence, and one certainly does not want...

COVID-19 changed consumers' spending patterns, making the CPI weights suddenly obsolete. In most regions, adjusting the CPI weights to account for the changes in spending patterns increases the estimate of inflation over the early months of the pandemic. Under-weighting of rising food prices and...

The standard measure of core or underlying inflation is the inflation rate excluding food and energy prices. This paper constructs an alternative measure, the weighted median inflation rate, for 38 advanced and emerging economies using subclass level disaggretion of the CPI over 1990-2021, and...

Consumer price indexes (CPIs) are compiled at the higher (weighted) level using Laspeyres-type arithmetic averages. This paper questions the suitability of such formulas and considers two counterpart alternatives that use geometric averaging, the Geometric Young and the (price-updated) Geometric...

This paper investigates the response of consumer price inflation to changes in domestic fuel prices, looking at the different categories of the overall consumer price index (CPI). We then combine household survey data with the CPI components to construct a CPI index for the poorest and richest...

This paper estimates the pass through of VAT changes to consumer prices, using a uniquedataset providing disaggregated, monthly data on prices and VAT rates for 17 Eurozonecountries over 1999-2013. Pass through is much less than full on average, and differsmarkedly across types of VAT change....

In closed or open economy models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. We analyze this result in the context of developing economies, where a large proportion of households are credit constrained...

This paper analyzes how the formation of Global Value Chains (GVCs) has affected the exchange rate elasticity of exports. Using a panel framework covering 46 countries over the period 1996-2012, we first find some suggestive evidence that the elasticity of real manufacturing exports to the Real...

It has been well-established in the literature that portfolio inflows appreciate the real effective exchange rate. However, the literature lacks a systematic empirical analysis of the impact of portfolio inflows by institutional sector or borrower type. This paper fills this gapby exploring the...

This paper contrasts real exchange rate (RER) measures based on different deflators (CPI, GDP deflator, and ULC) and discusses potential implications for the link-or lack thereof-between RER and external balance. We begin by documenting patterns in the evolution of different measures of RERs,...
