Book Description
The measurement of price dynamics is by no means new endeavourin the official statistics but the process of establishing accurate price changes in time still remains challenging in many areas. One such demanding field is the application of appropriate techniques in price index development for providing amendments reflecting quality differences which might occur in the compared commodities. The book presents results of research on the applicability of hedonic methods in adjusting price indices to changes in the goods quality and test the techniques used for hedonic price indices construction using the data sets for various groups of heterogeneous goods, including used automobiles, appartments, household appliances and ICT goods.

Using Hedonic Methods for Quality Adjustment in the CPI
Author: Mary Kokoski
Publisher: CreateSpace
ISBN: 9781491214534
Category : Reference
Languages : en
Pages : 54
Book Description
There has been strong recommendation that the BLS explore the use of hedonic methods forquality adjustment in the Consumer Price Index (CPI) for decades. The Price Statistics ReviewCommittee (the Stigler Commission Report) in 1961 expressed the view that hedonic analysis would provide a “more objective” approach to addressing quality change than the BLS standard methods of dealing with this issue (Triplett (1990)). More recently, the Advisory Commission to Study theConsumer Price Index (the Boskin Commission Report, 1996) reiterated this recommendation,recognizing that accurate measures of quality change will enable a more accurate measure of pure price,or “cost-of-living” change. Categories of goods and services where quality changes are frequent andrelatively easy to identify are the best candidates for using hedonic methods, given that data can beacquired.

Book Description
Accurate, real-time measurements of price index changes using electronic records are essential for tracking inflation and productivity in today's economic environment. We develop empirical hedonic models that can process large amounts of unstructured product data (text, images, prices, quantities) and output accurate hedonic price estimates and derived indices. To accomplish this, we generate abstract product attributes, or "features," from text descriptions and images using deep neural networks, and then use these attributes to estimate the hedonic price function. Specifically, we convert textual information about the product to numeric features using large language models based on transformers, trained or fine-tuned using product descriptions, and convert the product image to numeric features using a residual network model. To produce the estimated hedonic price function, we again use a multi-task neural network trained to predict a product's price in all time periods simultaneously. To demonstrate the performance of this approach, we apply the models to Amazon's data for first-party apparel sales and estimate hedonic prices. The resulting models have high predictive accuracy, with R 2 ranging from 80% to 90%. Finally, we construct the AI-based hedonic Fisher price index, chained at the year-over-year frequency. We contrast the index with the CPI and other electronic indices.

Quality Adjustment at Scale
Author: Gabriel Ehrlich
Publisher:
ISBN:
Category :
Languages : en
Pages : 0
Book Description
This paper explores alternative methods for adjusting price indices for quality change at scale. These methods can be applied to large-scale item-level transactions data that includes information on prices, quantities, and item attributes. The hedonic methods can take into account the changing valuations of both observable and unobservable characteristics in the presence of product turnover. The paper also considers demand-based approaches that take into account changing product quality from product turnover and changing appeal of continuing products. The paper provides evidence of substantial quality-adjustment in prices for a wide range of goods, including both high-tech consumer products and food products.

Price Index Concepts and Measurement
Author: W. Erwin Diewert
Publisher: University of Chicago Press
ISBN: 0226148572
Category : Business & Economics
Languages : en
Pages : 531
Book Description
Although inflation is much feared for its negative effects on the economy, how to measure it is a matter of considerable debate that has important implications for interest rates, monetary supply, and investment and spending decisions. Underlying many of these issues is the concept of the Cost-of-Living Index (COLI) and its controversial role as the methodological foundation for the Consumer Price Index (CPI). Price Index Concepts and Measurements brings together leading experts to address the many questions involved in conceptualizing and measuring inflation. They evaluate the accuracy of COLI, a Cost-of-Goods Index, and a variety of other methodological frameworks as the bases for consumer price construction.
