The paper reviews the sources of «Upward bias» and «Downward bias» in the USConsumer Price Index (CPI) and discusses the changes the Bureau of Labor Statistics has introduced in order to eliminate them. The remaining biases are quantified. Also, the question is raised how much the changes to...

Lacking data on price levels across locations (countries, national regions, etc.) for cross-space comparisons, researchers resort to local consumer price indexes (CPIs) over time to evaluate these levels. This approach unfortunately fails to specify, even generally, the exactness of such...

The paper presents a method to classify the dynamic patterns of the whole set of sub-indices that make up the harmonised index of consumer prices (HICP) and to assess the comparability of the national series referred to a same elementary aggregate of the target consumption expenditure. We...

The main approaches to measuring hedonic indexes in the academic literature are the imputation approach and the time dummy approach. This paper compares both approaches, discusses an alternative method called hedonic re-pricing, and comments on a recent contribution by Diewert et al. (2009). The...

This paper sets out a general algorithm for calculating true cost-of-living indices or true producer price indices when demand is not homothetic, i.e. when not all expenditure elasticities are equal to one. In principle, economic theory tells us how we should calculate a true cost-of-living...

The aim of this paper is to estimate the changeover's inflationary impact in Italy and Milan and make an assessment of the official methodology used by the National Institute of Statistics (ISTAT). The changeover's inflationary impact has been estimated in 0.6-0.7 percentage points in Italy,...

This paper explores the determinants of the heterogeneity in the expenditure behaviors of the Italian households, using the Households Expenditure Survey provided by the Italian National Institute of Statistics (ISTAT) for the year 2005. We assume that differences among consumers are associated...

This paper studies monetary policy rules in a small open economy with Inflation Targeting, incomplete pass-through and rigid nominal wages. The paper shows that, when nominal wages are fully flexible and pass-through is low to moderate, the monetary authority should target the consumer price...

The objective of this research paper is to examine the relationship between relative price variability and inflation by using consumer price index (CPI) of Pakistan. The outcomes of the research further divided into food and non-food groups too. The monthly data of CPI was taken from the...
