Economic valuation is widely used in OECD countries as a way of assessing the (usually monetary) value of goods that have no markets. In the rural context, valuation methods are used to argue for or against projects and policy choices in areas as diverse as agricultural support policies, local economic development, land use and biodiversity assessment.This volume reviews a range of different valuation methodologies -- stated preferences, cost-benefit, revealed preferences, and others -- and looks at how these different approaches influence choices in rural policy. Its aim is to assess whether some set of international guidelines or standards could be used to reduce the subjectivity of the evidentiary information.
