Van Veelen and van der Weide (2008) in a recent paper provided some interesting new perspectives on the index number problem. However, the present paper argues that their definitions of a true index and an exact index are different from the standard definitions in the literature. The differences...

The traditional economic approach to index number theory is based on a ratio concept. The Konüs true cost of living index is a ratio of cost functions evaluated at the same utility level but with the prices of the current period in the cost function that appears in the numerator and the prices...

The paper uses hedonic regression techniques in order to decompose the price of a house into land and structure components using real estate sales data for Tokyo. In order to get sensible results, a nonlinear regression model using data that covered multiple time periods was used. Collinearity...

This paper reviews the theory of the true cost of living index and its approximation through superlative index numbers, as well as the Vartia quantum theory of bias in index numbers as applied to substitution bias in consumer price indices. Estimated adjustments are proposed for the Argentine...

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 our paper is to discuss the problems of operationalizing the concept of a .cost-of-living-index. (COLI). For this purpose we are first undertaking a theoretical analysis of Diewert’s theory of superlative index numbers as one possible approach to approximate a COLI. We show that...

Using non-parametric weak separability tests that are extended to allow for measurement errors in the data, a broad group of UK monetary assets is found to be weakly separable from consumer goods and leisure over the larger part of the nineties. Financial innovations have made assets with...

The paper presents a revision of the contemporary reductionistic demand theory, replacing the studying object, i.e. an individual, with a fuzzy collection of market buyers, regarded as a “statistical ensemble of consumers”. The new holistic market demand theory formally retains the...
