This paper is divided into two parts which deal with closely connected issues, The first section of the paper explores the structure of consumer demand systems necessary and sufficient for exact aggregation. The second section addresses a related empirical question: what, if anything, do the...

Ordinary consumer price indices customarily overstate increases in the cost of living because they do not allow for consumer substitution as relative prices change. This study looks for a more accurate measure of variations in the cost of living in Argentina over the years 1960 to 1995, taking...

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...

Policy analysis frequently requires estimates of aggregate (or mean) consumer elasticities. However, estimates are often made incorrectly, based on elasticity calculations at mean income. We provide in this paper an overall integrated analytical framework that encompasses these biases and...

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...

We establish the Hurwicz-Uzawa integrability of the broad class of discrete-choice additive random-utility models of individual consumer behavior with perfect substitutes preferences and divisible goods. We derive the corresponding indirect uility function and then establish a representative...

This paper analyzes the relationship between the demand for tobacco, its price and the economic factors that may influence it. The objective is to understand the response of consumers to an increase in tobacco prices. The price increase is assumed to be caused by the effect of increasing tobacco...
