Stated Preference Methods & Valuing Surface Water Quality Improvements

Seminar presented by Dennis Guignet of the US Environmental Protection Agency, National Center for Environmental Economics.

This presentation will describe the use of Stated Preference (SP) methods, a survey based technique often used by economists to estimate the benefits of environmental policies. Focusing on improvements in surface water quality, we will describe why SP methods are sometimes needed, and demonstrate an application using a recent study of the Chesapeake Bay Total Maximum Daily Loads.  We will then describe one of the biggest challenges economists face in designing a valid SP survey instrument - what is the appropriate metric to measure and communicate improvements in environmental quality?  This is a particular challenge when trying to define the commodity using a consistent metric across heterogeneous environmental features, over broader geographic regions. We will compare and contrast the approach taken in the above Chesapeake Bay study with an alternative index based approach. In particular, we will discuss a proposed metric of aquatic ecosystem health that could potentially be applied across the contiguous US, and elicit feedback on this preliminary metric and the available data.


SESYNC seminars are open to all interested attendees. Join us in Annapolis!
