We test the reliability of international BT and Delphi CV estimates by comparing them to a population CV survey of Norwegian households’ willingness-to-pay (WTP) for Amazon Rainforest preservation plans. The Delphi CV method predicts WTP and scope effects in line with conventional BT, motivating further testing of the Delphi CV method as a time- and cost-saving way of valuing global public goods.
