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. In this paper two methods are compared which can be used to eliminate...

Utilizando parcialmente el enfoque propuesto por Diewert (1998), se estiman los sesgos por sustitución de productos genéricos, por puntos de compra y por mejoras de calidad del índice de precios al consumidor mexicano. El principal resultado indica la existencia de un sesgo al alza de...

La literatura especializada reconoce la existencia de sesgos potenciales en el índice de precios al consumidor. Utilizando índices de precios hedónicos generados por el Bureau of Labor Statistics, el ajuste al precio de los automóviles propuesto por Izquierdo, Licandro y Maydeu (2001), y los...

Consumer-related policy decisions often require analysis of aggregate responses or mean elasticities. However, in practice these mean elasticities are seldom used. Mean elasticities can be approximated using aggregate data, but that introduces aggregation bias for full and compensated price...

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...

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 paper reviews and extends the theory of exact and superlative index numbers. Exact index numbers are empirical index number formula that are equal to an underlying theoretical index, provided that the consumer has preferences that can be represented by certain functional forms. These exact...

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...

This paper develops a new framework for empirical modelling of consumer demand with particular reference to products that are differentiated with respect to quality and location attributes. The point of departure is a flexible representation of the distribution of product attributes and consumer...

In this paper we discuss statistical inference associated with the theoretical model developed in Part I. Specifically, we demonstrate how the relationship between the distribution of prices and unit values can be exploited to estimate some of the structural parameters. These estimates are...
