This paper presents a multinational meta-analysis estimated to identify systematic components of willingness to pay for surface water quality improvements, developed to support benefit transfer for Canadian policy development. Metadata are drawn from stated preference studies that estimate WTP for water quality changes affecting aquatic life habitats—a type of study with few Canadian examples. The goals of this paper are to assess the properties of a multinational (United States/Canada) meta-analysis compared to a single-country (U.S.) analog; illustrate the potential information that may be derived as well as the analytical challenges; and assess the performance of resulting meta-functions for benefit transfer.


<em>Abstract.</em>—In this paper, we provide an introduction to water quality benefit estimation for noneconomists. Net water quality benefits are typically measured using the concept of consumer surplus, which is estimated using a number of economic valuation methodologies. These are divided into direct and indirect methods. Direct methods involve questioning survey respondents to determine their consumer surplus. Indirect methods use data from consumer market behavior to estimate economic values. When limited time or funding preclude costly data collection and the development of new consumer surplus estimates, the method of benefit transfer is used to tailor preexisting consumer surplus estimates to fit new policy situations. We provide an example of benefit transfer by estimating the value of water quality improvements for the Cape Fear River in North Carolina. Benefit transfer methods are used with three valuation approaches to estimate the benefits of water quality improvement.

Economic valuations of the environmental resources provided by the waterways of South East Queensland are required for the evaluation of proposed environmental management strategies. Due to time and funding constraints it is unlikely that the environmental resources for each tributary of the river system will be subject to individual and explicit valuation. This paper reviews the literature about the validity of environmental benefit transfer, identifying the protocol for undertaking such a study. It then describes a study designed to transfer the estimated value of water quality improvements for the Bremer River to other waterways in South East Queensland. The study addresses some of the shortcomings of stated preference techniques to value the environment, including improving the quality of the information provided to survey respondents and the reliability of their responses by adopting a citizens' jury approach to the valuation exercise. In addition, the study is expected to provide the results in a form that will facilitate the estimation of a demand function for water quality improvements that will be meaningful for environmental value transfer to other sites with similar water quality issues.
