Quality Adjustment at Scale


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.




Assessment of Rehabilitative and Quality of Life Issues in Litigation


Book Description

Written in response to the Supreme Court's landmark Daubert decision regarding provision of expert witness scientific testimony, Assessment of Rehabilitative and Quality of Life Issues in Litigation focuses on quality of life as a means of conceptualizing and measuring pain and suffering in the controversial enjoyment of life debate. The authors make a compelling argument for a quality of life paradigm based on a rehabilitation and health economics analysis, demonstrating that qualified rehabilitationists are the best experts to provide analyses of the impact of disability or injury on quality of life over the lifespan. The extensive literature review enables attorneys and litigation experts to easily access quality of life literature.




Quality


Book Description

Quality, as exemplified by Quality-of-life (QoL) assessment, is frequently discussed among health care professionals and often invoked as a goal for improvement, but somehow rarely defined, even as it is regularly assessed. It is understood that some medical patients have a better QoL than others, but should the QoL achieved be compared to an ideal state, or is it too personal and subjective to gauge? Can a better understanding of the concept help health care systems deliver services more effectively? Is QoL worth measuring at all? Integrating concepts from psychology, philosophy, neurocognition, and linguistics, this book attempts to answer these complex questions. It also breaks down the cognitive-linguistic components that comprise the judgment of quality, including description, evaluation, and valuations, and applies them to issues specific to individuals with chronic medical illness. In this context, quality/QoL assessment becomes an essential contributor to ethical practice, a critical step towards improving the nature of social interactions. The author considers linear, non-linear, and complexity-based models in analyzing key methodology and content issues in health-related QoL assessment. This book is certain to stimulate debate in the research and scientific communities. Its forward-looking perspective takes great strides toward promoting a common cognitive-linguistic model of how the judgment of quality occurs, thereby contributing important conceptual and empirical tools to its varied applications, including QoL assessment.

Using Machine Learning to Construct Hedonic Price Indices


Book Description

This paper uses machine learning (ML) to estimate hedonic price indices at scale from item-level transaction and product characteristics. The procedure uses state-of-the-art approaches from hedonic econometrics and implements them with a neural network ML approach. Applying the methodology to Nielsen Retail Scanner data leads to a large hedonic adjustment to the Tornqvist index for food product groups: Cumulative food inflation over the period from 2007 through 2015 is reduced by half from 5.9% to 2.8% -- owing to quality adjustment. These results suggest that quality improvement via product turnover is important even in product groups that are not normally considered to feature rapid technological progress. The approach in the paper thus demonstrates the feasibility and importance of implementing hedonic adjustment at scale.
