This research introduces a new value elicitation method for non-market valuation, referred to as the “quasi-double-bound (QDB)” method, applied to the case of barrierisland restoration in Mississippi. The objective of this thesis is to implement the QDB method in an actual stated-preference survey instrument and to test empirically whether the method elicits consistent responses and yields more efficient welfare estimates relative to the more-commonly used single-bound (SB) method. To test the QDB method, several models were estimated to derive a variety of welfare estimates for comparison to the estimates derived from the SB method. The QDB method introduced here results in a median willingness to pay (WTP) that was higher than the estimate of median WTP using the SB method in three of the five models estimated. The variances (i.e., confidence interval) of the QDB models were generally lower than those of the SB models.
