This paper introduces an alternative non-market value elicitation method—the “quasi-doublereferendum” (QDR)—applied to barrier island restoration in Mississippi. It is appropriate for surveys that elicit willingness-to-pay responses to multiple projects differing in scale only and can be used to increase efficiency while mitigating bias. We compare results to the more commonly used single-referendum (SR) method under two admissible ranges of willingness to pay: negative to positive infinity, and zero to income. The confidence intervals of the QDR models were narrower. We argue that the QDR approach should be less subject to bias than the commonly used double-referendum approach.

Agricultural nitrogen is a major contributor to Gulf of Mexico hypoxia, and research has shown that agricultural subsurface tile drainage is a major carrier of nitrogen from croplands to streams and rivers. This study compares the results of abating nitrogen under a retired-land minimization policy with those of a new revenue-maximizing policy, paying particular attention to the role of tile-drained land. Findings reveal the retirement-minimizing policy resulted in more tile-drained land being retired and less being fertilizer-managed than was optimal under the net-return maximizing policy. Also, it led to a greater economic burden being shouldered by tile-drained land. Under both cases, tile drainage dominated the abatement process.
