![]() Economics gives us a way to compare the possible benefits of a policy with its possible costs. Multiple studies show that people place an economic value on, or a “willingness to pay” for better visibility (What is a Clear View Worth?). These economic benefits are usually a part of the cost-benefit analyses for air quality regulations. Economic benefits from visiting parks depend on protection of park natural resources, including air quality. Visitor spending in communities around national park sites was estimated at 11.9 billion dollars in 2009. Visitor surveys regularly show that visitors think clean, clear air is extremely important. |
