The Boskin report (1996) concluded that the US consumer price index (CPI) overestimated the inflation by 1.1 percentage points. This was due to several measurement errors in the CPI. One of them is called quality change bias. We compare two methods in this paper which can be used to correct for...

This paper presents a revealed preference method for calculating a lower bound on the virtual or reservation price of a new good and suggests a way to improve these bounds by using budget expansion paths. This allows the calculation of cost-of-living and price indices when the number of goods...

This paper studies the problems of measuring economic growth under conditions of high inflation. Traditional bilateral index number theory implicitly assumes that variations in the price of a commodity within a period can be ignored. In order to justify this assumption under conditions of high...

This paper reviews alternative approaches to measuring an economy´s cost competitiveness and proposes some new measures derived from the economic theory of index numbers. The indices provide a theoretical benchmark for estimated real effective exchange rates, but differ from standard measures...

In some countries a Paasche price index based on unit values is compiled as a proxy for a true Paasche (or Laspeyres) price index on the basis of prices. This is for example the case in German foreign trade statistics. Unit values are average prices referring to a 'commodity number' (CN), that...

A dynamic model of consumer behavior that incorporates the demand for housing is specified such that it is consistent with the general purpose of a consumer price index. From this model a true cost-of-living index that includes housing is derived. Being an ideal index it cannot be computed...

This paper uses index number theory to disentangle changes in aggregate retail interest rates due to changes in individual component rates (“interest rate effect”) from those caused by changes in the weights of each component (“weight effect”), on the basis of the “difference” index...

The process of globalization is an international economic order which has led to the progressive integration of the world economy through the pulling the barrier of trade and greater mobility of factors of production. In addition the technological innovation also provides impetus to the...

The goal of this paper is to theoretically and empirically demonstrate the consequences of different imputation methods, using recent data from the International Price Program. We suppose that prices are missing due to random or erratic reporting. We consider three different imputation methods:...

We combine the ideas of the trimmed mean and the Edgeworth index to construct an alternative measure of core inflation named Trim of Most Volatile Components (TMVC). At each point of time this measure trims away the components of the price index, which have been most volatile in the past. TMVC...
