McConnell, "Hedonic and Travel Cost Models," Land Economics, Vol. 66, No. 2 (May 1990), pp. 121-127. 24519 McConnell concludes that if an hedonic study indicates that PCB contamination affects housing prices, the housing price impacts cannot be added to impacts derived from travel cost analyses of recreation use to determine the total impacts. 24520 McConnell concludes that using the results of hedonic studies along with those of recreation demand studies based on travel costs involves double counting. 24521 Even if an hedonic or repeat sales study purports to indicate that PCB contamination affects housing prices, the housing price impacts cannot be added to impacts derived from travel cost analyses of recreation use to determine the total impacts. 24522 Using the results of hedonic or repeat sales studies along with those of recreation demand studies based on travel costs involves double counting. 24523 An econometric model designed to explain variations in housing prices by variations in exposure to PCB pollution is not valid when it relies on a sample of houses for which the level of exposure to PCB pollution does not vary. 24524 An econometric model designed to explain variations in housing prices by variations in exposure to PCB pollution must be able to hold the influences of other factors constant. 24525 A repeat sales study requires accurate data on market prices of houses and on the dates of the transactions. 24526 If a repeat sales study relies only on information for houses that were equally affected by the presence of PCBs in New Bedford Harbor, the effects of PCBs on real estate prices cannot be distinguished from the effects of other local market forces. 24527 The New Bedford Harbor is polluted with raw sewage and untreated wastewater. 24528 According to the assumptions that underlie Professor Mendelsohn's model, prospective homebuyers would pay more for a house near unpolluted water that is in all other respects exactly the same as a house near polluted water, regardless of what pollutants are present in the polluted water. 24529 If a repeat sales study uses information on houses whose values were not equally affected by the presence of PCBs in New Bedford Harbor, and if the effect of PCBs on property values is influenced by other factors that determine property values, then the effects of these other factors must be included in an analysis of sale prices of houses. 24530 Professor Mendelsohn did not use all of the data that were available to him pertaining to housing characteristics and other factors that affect housing prices. 24531 Professor Mendelsohn intended to estimate a model using only single-family homes in single-family neighborhoods. 24532 Professor Mendelsohn included properties with rental units in his sample. 24533 If preferences shift over time so that houses adjacent to waters that are known to be polluted become less desirable, then property values adjacent to polluted waters will decline over time relative to other property values, all other factors being held constant. 24534 If variations in the level of PCBs and in the levels of other pollutants in New Bedford Harbor are perfectly correlated, then the effects of PCBs on property values cannot be distinguished from the effects of other pollutants, should such effects exist. 24535 If variations in the level of PCBs and in the levels of other pollutants in New Bedford Harbor are highly correlated, then it is very difficult to distinguish the effects of PCBs on property values from the effects of other pollutants, should such effects exist. 24536 If the variations in the level of PCBs and in the levels of other pollutants in New Bedford are not perfectly correlated, then a repeat sales study of the effects of PCBs on property values must control for the effects of other pollutants in New Bedford Harbor. 24537 The time period over which Professor Mendelsohn has observations on the sale prices of houses is 1969 through 1989, 21 years. 24538 It is unlikely that preferences for housing in the New Bedford area have remained constant over such a long period of time. 24539 It is likely that variations in PCB levels and the levels of other pollutants in the New Bedford Harbor are highly correlated. 24540 It would be very difficult to distinguish the effects of PCBs on housing prices from the effects of other pollutants on housing prices should such an effects exist 24541 A repeat sales study of the effects of PCBs on property values must control for the effects of other pollutants in New Bedford Harbor. 24542 The basis for repeat sales analysis is the relationship between the price of a house and the characteristics of the house and other factors that determine the price level. 24543 The basis for repeat sales analysis is hedonic price index analysis. 24544 The basic model equation for a repeat sales study should be specified in terms of the sales price of a house at a given time, rather than the change in price between two sales. 24545 A repeat sales model which purports to estimate the effects of PCBs on housing prices is not valid if it does not include all factors that affect housing prices that vary across time and across time and houses. 24546 Attachment Q.VIII.d.7 is a true and accurate copy of an article by Karl E.
