Improper quality adjustment has long been identified as a source of potential measurement bias in consumer price indices (CPIs). However, as no benchmark for quality adjustment exists, it has always been difficult to estimate a potential bias. For this paper, we develop a corridor in which...

We use CPI micro data for nine euro area countries to document new evidence on consumer price stickiness in the euro area during the 2021-2024 inflation cycle. In 2022, the monthly frequency of price changes reached 12%, compared with an average of 8% over 2010-2019, roughly a...

We estimate daily wage rates for skilled and unskilled construction workers and agricultural laborers in Switzerland from 1750 to 1860, a period of profound political and economic transformations. Our analysis is based on 17,700 newly collected wage quotes from primary sources and 23,300 price...

This paper estimates the pass-through of world oil price innovations to Philippine fuel prices and headline CPI, and decomposes total CPI pass-through into a fuelbasket component and a residual non-fuel component. Using a recursive SVAR and 25 years of monthly Department of Energy pump price...

In diesem Artikel werden Möglichkeiten der Fortschreibung per Stichprobe für qualifizierte Mietspiegel beschrieben und aus Sicht der Statistik hinsichtlich ihrer Umsetzbarkeit und Qualität eingeordnet. Die Anwendung auf reale Daten des Mietspiegels für München zeigte im Vergleich zu einer...

Measuring aggregate inflation is subject to two opposing biases: unobserved quality and variety growth, and the use of incorrect weights when new varieties are misclassified. We show that it is possible to measure an aggregate price index free of these biases when we have a subset of products...

In this article, we examine the dynamic interdependencies among components of Japan's consumer price index (CPI) using a two-lag time-varying loading factor (TLTVLF) model. Whereas previous studies have typically decomposed CPI series into long-term trends, seasonal patterns, and cyclical...

The objective of this research is to analyze the impact of consumer price index, exchange rate, broad money supply, and export on tax revenue in Cambodia. The short-run effects from the ARDL cointegration model suggest that inflation negatively influences tax revenue. Changes in the exchange...

Die Nutzung von Scannerdaten in der Verbraucherpreisstatistik hat viele Vorteile, bringt allerdings auch einige Herausforderungen mit sich. Eine der Herausforderungen ist die Klassifizierung der Artikel nach dem vom Verbraucherpreisindex verwendeten Klassifikationssystem COICOP. Aufgrund der...

The rise in inflation in recent years triggered a cost-of-living crisis, in which households' ability to afford basic necessities declined. The cost-of-living crisis disproportionately affected lower income households, with the proportion in material deprivation (i.e. unable to afford basic...

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...
