This paper uses the interval data model to explore the determinants of uncertainty in two-way payment ladder and in multiple-bounded uncertainty choice surveys. It estimates the uncertainty function that relates the size of the willingness-to-pay range to explanatory variables, where one of them...

The European COST Action E45 on European Forest Externalities (EUROFOREX) participants developed a set of good practice guidelines for the non-market valuation of forests, elaborating on stated and revealed preference methodologies, as well as benefit transfer and meta-analytical procedures....

Choice Modelling applications can be designed to estimate main effects only or multiple-way interactions between attributes. It has been reported that higher order effects generally account for less than 10% of the choice explanation. Nevertheless, the amount of applications testing for...

Cheap talk (CT) scripts have been broadly tested in contingent valuation studies to mitigate the effects of hypothetical bias. However, this approach may not fully be adequate when the individual is faced with several choices such as in discrete choice experiments (DCE) because the respondent...

Different instruments have been developed to mitigate the hypothetical bias in contingent valuation surveys. One, labelled ‘cheap talk’, warns participants about the hypothetical bias phenomenon prior to the valuation question. This paper investigates the effects of cheap talk on...

<italic>Several countries may adopt the euro in the near future. Whether the change of currency may lead to different responses in non-market valuation surveys remains an open question. A contingent valuation application was carried out shortly after the changeover to the euro in Spain, with half of the...</italic>

Rating-type questions are sometimes used in valuation surveys. Responses have to be treated with care since individuals may perceive the scale differently. In order to study this issue, ratings provided by respondents in a survey designed to compare two different choice tasks are used. The...
