Headline CPI, core CPI, and indices for various small expenditure categories were analyzed. Sustainable long-term linear trends have been found in the difference between the headline CPI and these indices. Overall, the results completely support our previous findings for such principal...

This paper presents the geo-logarithmic family of price indexes and gives a new characterization of the Sato-Vartia index, showing that it is the only geo-logarithmic formula being factor reversible.

In this paper we adopt Group Theory to investigate the symmetry and invariance properties of price index numbers. An alternative treatment is given to the study of the reversibilty axioms, that clarifies their meaning and allows for a conceptual unification of this topic, within the framework of...

In recent years, it has become evident that pure monetary measures cannot represent the poverty phenomenon faithfully. Poverty involves many different aspects of life that can be hardly condensed in a single monetary indicator. People can be poor in different ways, at different degrees and from...

The period 1960 to 2007 – when the Cyprus pound was legal tender – is examined with a view to relating the major turning points of exchange, fiscal and monetary policies to their likely causes and consequences. Assumptions are made and conclusions are drawn regarding: the four periods of...

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:...

A long lasting controversy in Sweden as well as internationally is how to best estimate a price on the services of owner occupied housing in a consumer price index. There is no international consensus and different approaches have been adopted. In this paper we use a true cost-of-living index...

The consumer price index (CPI) is usually computed as a fixed-weighted Laspeyres price index, with the weights updated at discrete intervals only. It is well known that the Laspeyres functional form entails a substitution bias. One way to reduce it would be to use chained indices, and...

The Sydney housing market peaked in 2003. The period 2001-2006 is, therefore, of particular interest since it captures a boom and bust in the housing market. We compute hedonic, repeat-sales and median price indexes for five regions in Sydney over this period. While the three approaches are in...

Panel hedonic comparisons can be made using the region-time-dummy method. This method is a natural extension of the well known time-dummy and region-dummy methods which have been used extensively in the hedonic literature. We show that these methods are all affected by substitution bias, which...
