Book Synopsis The Difference Between Hedonic Imputation Indexes and Time Dummy Hedonic Indexes by : Mick Silver

Download or read book The Difference Between Hedonic Imputation Indexes and Time Dummy Hedonic Indexes written by Mick Silver. This book was released on 2006-07. Available in PDF, EPUB and Kindle. Book excerpt: Statistical offices try to match item models when measuring inflation between two periods. For product areas with a high turnover of differentiated models, however, the use of hedonic indexes is more appropriate since they include the prices and quantities of unmatched new and old models. The two main approaches to hedonic indexes are hedonic imputation (HI) indexes and dummy time hedonic (DTH) indexes. This study provides a formal analysis of the difference between the two approaches for alternative implementations of the Törnqvist "superlative" index. It shows why the results may differ and discusses the issue of choice between these approaches.
