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...

Intertemporal consumer preference shifts, although common in modern macro-economic models as drivers of demand shocks, have important but largely unexplored implications for price index theory and thus, for empirically measured price changes. The current practice of inflation measurement...

The effect on the household consumption price index from possible sources of error in capturing digital products depends on the weight of the affected products. To calculate upper bounds for this effect, we apply weights based on the average structure of household consumption in OECD countries...

People dislike inflation because inflation erodes the real value of future nominal income and wealth. Adjustment of future nominal values via a cost of living index is an appropriate way to handle the problem of real income risk. Nonetheless an important aspect needs more discussion: If markets...

We study the properties of a profit-maximizing monopolist's optimal price distribution when selling to a loss-averse consumer, where (following Kőszegi and Rabin (2006)) we assume that the consumer's reference point is her recent rational expectations about the purchase. If it is close to...

This paper looks at the problems associated with the treatment of seasonal commodities in a consumer price index. Economic assumptions behind various commonly used methods are examined from the cost-of-living perspective. Other economic issues concerning seasonal commodities are also discussed....

We present a revealed preference methodology for nonparametric demand analysis under the assumption of normal goods. Our methodology is flexible in that it allows for imposing normality on any subset of goods. We show the usefulness of our methodology for empirical welfare analysis through cost...

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...

We simulate the welfare effects of the Carbon-Energy Tax introduced in Italy at the beginning of 1999 which asks for smooth increases, over a number of years, in the prices of most fossil fuels. The welfare effects have been calculated using True Cost of Living index numbers and their parameters...
