An Economic Evaluation of Redundancy for Trunk Transportation Network Formation by Contingent Valuation Method: A View Point of Payment Vehicle Bias

Abstract

The purpose of this paper is evaluate to redundancy function for trunk transportation network formation by Contingent Valuation Method (CVM). This paper discuss that this CVM study have found that WTP varies depending whether afinancial expenditure allocation or a donation is used as a payment vehicle. To minimize this bias, we clarify that controversial vehicle should be avoided and a method which is most likely to be used in real situation to elicit payment.
