The amenity value of woodland in Great Britain: A comparison of economic estimates

Forests produce benefits over and above the revenue yielded from timber and other wood based products. Most important among these may be the recreational benefits for visitors, which have been examined in several studies. Total benefits for residents are perhaps more accurately captured in property values since, ceteris paribus, the price of a house reflects willingness to pay to live near an environmental amenity such as a forest to gain access to it, and also the amenity (non-use) value of the forest in so far as it creates a pleasant landscape. However, the total non-priced value of forestry is not the sum of HPM and ITCM benefit estimates. Recreational benefits will typically be less, and will be subsumed in the HPM estimates, since the hedonic price is partly induced by the value of recreational access.

Hedonic models and air pollution: Twenty-five years and counting

This paper reports a meta analysis of how effectively hedonic property models have detected the influence of air pollution on housing prices. Probit estimates are reported describing how data, model specification, and local property market conditions in cities represented in thirty-seven studies influence the ability of hedonic models to uncover negative, statistically significant relationships between housing prices and air pollution measures.Partial support for this research was provided by the Russell Sage Foundation. Thanks are due David Cordray, Heidi Hartman, and Larry Hedges of the Foundation's Meta-Analysis Panel for constructive comments, to Ray Palmquist for suggestions and assistance in assembling the results from his studies, to Rick Freeman and Tom Tietenberg and two anonymous referees for comments on the research, and to Barbara Scott for constructive editing of earlier drafts of this paper.
