Quality measurement in economics

the long version

"The concept of quality measurement is revived and given new meaning in this innovative new book. Steven Payson argues that quality measurement is an important issue in the study of price indices and in the additional areas of product innovation and evolutionary change. The user-value definition of quality is forcefully defended against the producer-cost definition, and a new method of measurement is introduced - the representative good approach (RGA). The RGA provides a new means for measuring quality over long periods of time by examining historical documents. A discussion of evolutionary change lays the groundwork for the identification of two processes: quality improvement and cost reduction. Using data from the Sears Catalog, quality improvement and cost reduction rates are estimated for five goods between 1928 and 1993: shoes, sofas, gas ranges, window fans and air conditioners, and cameras. The results are dramatic, supporting ground-breaking hypotheses on the determinants of quality improvement and cost reduction."--BOOK JACKET.
