      abstract = {A recent concern in the valuation literature is the  uncertainty respondents feel when
posed with  willingness-to-pay questions for environmental amenities in  hypothetical
market scenarios. Using a multiple-bounded  discrete-choice format, the results
indicate that  respondents become less ambivalent when allowed  considerable time to
think about the valuation task before  a response is elicited. In particular they tend to
reduce  the reported willingness to pay associated with low  certainty of paying, hence
resulting in more conservative  welfare estimates. Implications for the application  of
environmental valuation techniques are discussed.},
