This study tests the hypothesis that hypothetical bias may not be related to value elicitation; rather it may be a value formation problem. When participants are asked to indicate their willingness to pay for an induced value good, we find no evidence of hypothetical bias for three different...

Individuals are widely believed to overstate their economic valuation of a good by a factor of two or three. This paper reports the results of a meta-analysis of hypothetical bias in 28 stated preference valuation studies that report monetary willingness-to-pay and that used the same mechanism...

Eliciting sincere preferences for non-market goods remains a challenge due to hypothetical bias - the so-called gap between hypothetical monetary values and real economic commitments. The gap arises because people either overstate hypothetical values or understate real commitments or a...

Eliciting sincere preferences for non-market goods remain a challenge due to the discrepency between hypothetical and real behavior and false zeros. The gap arises because people either overstate hypothetical values or understate real commitments or a combination of both. Herein we examine...

Stated preference methods using surveys to elicit willingness to pay have been shown to suffer from hypothetical bias and scope/scale bias. Hypothetical bias usually means that willingness to pay is exaggerated in the hypothetical scenario and scope/scale bias means that there is an...

Hypothetical bias is a serious problem of stated preference techniques. The certainty approach calibrates answers by assessing different weights to remedy respondents' valuation. However, very little research has been done to find a link between economic theory and empirical treatment of...

Each year during the turtle watching season, Mon Repos turtle rookery in Queensland attracts many ecotourists interested in seeing sea turtles nesting or hatching. As part of their visit, visitors are able to learn about the biology of and threats to marine turtles. A sample of visitors were...
