We develop a new but simple non-parametric method to diagnose inconsistency in double-bounded contingent valuation questions in the presence of both perfect and imperfect correlation between initial and follow-up response distributions. The proposed method can identify inconsistency in iterative...

A nationwide survey was conducted to estimate welfare associated with a proposed large-scale wetland restoration project in coastal Louisiana. Both binary- and multinomial-choice survey instruments were administered via Knowledge Networks, with the latter used to estimate willingness to pay for...
