Hedonic pricing is a model, which identifies price factors, according to the premise that price is determined both by internal characteristics of the good being sold and external factors affecting it. Without quality adjustment we see an annual average growth in prices of new cars of about 5.37%. Hedonic quality adjustment on the basis of overlapping characteristics reduces this to an annual average growth rate of 3.45%. The Hedonic Imputation Method and the Price Index Problem Robert J.

Using decennial census data, they documented that all else equal that the implicit price on winter temperature has been rising over time in hedonic real estate regressions. Hedonic pricing is a model, which identifies price factors, according to the premise that price is determined both by internal characteristics of the good being sold and external factors affecting it.
