Wrażliwość hedonicznych indeksów cen na przykładzie indeksów cen dzieł znanych malarzy polskich
Sensitivity of hedonic price indexes on the example of the art price indexes evaluated for well-known Polish painters

Summary/Abstract: The aim of the research is construction and evaluation of the hedonic price indexes for Polish paintings. In the paper we discuss basic problems concerning specification of the model which describes artworks prices, employing qualitative characteristics. Empirical investigation is conducted on the basis of individual data concerning auctions of paintings that took place in Poland in years 2007-2010. We show that different specification of hedonic models and changes of the sample containing traded objects significantly affect index value. We propose construction of aggregated indexes that are less sensitive to the single model specification.
