Commercial Property Price Indexes


Book Description

Transaction-price residential (house) and commercial property price indexes (RPPIs and CPPIs) have inherent problems of sparse data on heterogeneous properties, more so CPPIs. In an attempt to control for heterogeneity, (repeat-sales and hedonic) panel data regression frameworks are typically used for estimating overall price change. We address the problem of sparse data, demonstrate the need to include spatial price spillovers to remove bias, and propose an innovative approach to effectively weight regional CPPIs along with improvements to higher-level weighting systems. The study uses spatial panel regressions on granular CPPIs for the United States (US).

























Adjusting Quality Index Log Values to Represent Local and Regional Commercial Sawlog Product Values


Book Description

S2The primary purpose of this paper is not only to report the results of a comparative analysis as to how well the Q.I. method predicts log product values when compared to commercial sawmill log output values, but also to develop a methodology which will facilitate the comparison and provide the adjustments needed by the sawmill operator. The commercial sawlog values as derived in an independent study of seven sawmills in southeastern Ohio and eastern Kentucky were compared with Q.I. values developed for an analysis of log and tree valuation. (Whittaker and McCauley 1966). Six different species were compared: red oak, black oak, scarlet oak, white oak, chestnut oak, and yellow-poplar.S3.
