This study presents a comprehensive bibliometric and systematic literature review analysis of the literature on the Big Mac Index (BMI) to identify its foundational aspects and summarize key findings. The BMI, an informal measure of purchasing power parity, has garnered scholarly interest in...

This study investigates the main drivers of inflation measured by CPI inflation and GDP deflator across 20 advanced and emerging economies over the yearly span from 2014 to 2023. Using Principal Component Analysis and Panel Vector Autoregression, the research examines the roles of supply-side...

This study aims to construct a sentiment index for predicting CPI in Vietnam. Adopting a lexicon-based approach, the study utilized two widely recognized sentiment dictionaries, specialized in financial and economic contexts, to build the sentiment index. Data was mined from nine official...

We analyse potential mismeasurement of the Harmonised Index of Consumer Prices (HICP) at the upper level of aggregation, focusing on two sources of measurement error: the choice of index formula (representativity component) and the reliability of weights (data vintage component). The...

The Theory publication and the companion on the practice of compiling consumer price indices (CPIs) is jointly published by the member agencies of the Inter-Secretariat Working Group on Price Statistics (IWGPS): the Statistical Office of the European Union (Eurostat), the International Labour...

We provide new evidence that inflation inequality surged during the 2021–2023 cost-of living crisis, driven by systematically higher price growth for lower-quality goods disproportionately consumed by poorer households. While substitution in response to relative price changes helped mitigate...

In this paper, we evaluate a set of measures of underlying inflation for Germany using conventional measures, such as core inflation (excluding energy and food items), and alternative measures based on econometric models, machine learning, and micro-price evidence. We compare these measures...

Measures of inequality typically rely on price indices formulated for a representative consumer, falsely assuming an identical consumption basket across households within the country. However, consumption patterns differ across households; hence, the changes in price levels might have different...

We employ Synthetic Control Method techniques to estimate the causal effect of Brexit on the consumer price index (CPI) in the United Kingdom. We construct a counterfactual CPI index from a weighted pool of comparable economies and find that the price level of the United Kingdom rose...

Inflation is the percentage change in the CPI over a given period of time. It is usually calculated over a year (year-on-year inflation) and over a month (month-to-month inflation). Even if prices are not currently rising from month to month, the year-to-year inflation rate could still be...

This study compared standard VAR, SVAR with short-run restrictions, and SVAR with long-run restrictions to investigate the effects of oil price shocks and the foreign exchange rate (ZAR/USD) on consumer prices in South Africa after the 2008 financial crisis. The standard VAR model revealed that...

By comparing the Bundesbank's BOP-HH and the ECB's CES-ECB household panel surveys focusing on inflation perceptions and expectations with omnibus surveys conducted in Germany in December 2021 and 2022, this paper examines potential sample selection bias stemming from (i) individuals'...

Energy inflation is a major source of headline inflation volatility and forecast errors, therefore it is critical to model it accurately. This paper introduces a novel suite of Bayesian VAR models for euro area HICP energy inflation, which adopts a granular, bottom-up approach - disaggregating...

This study examines whether portfolio optimization can be effectively based on annual changes in the harmonized index of consumer prices (HICP) data. Specifically, we assess whether asset allocation based on consumer expenditure can generate superior returns compared to static or equal-weighted...
