Methods and results from a new survey of values for eastern regional haze improvements.

A contingent valuation survey was designed and implemented in 2003 to elicit the willingness to pay for haze reduction in scenic areas of the Eastern United States. This survey updated and enhanced a portion of a 1988 survey, Chestnut and Rowe's Preservation Values Study, which is commonly used to estimate benefits of haze reduction policies. The 2003 survey incorporated features to address criticisms of the 1988 survey regarding its lack of budget constraints and its simplistic descriptions of changes in visibility.
