| The contingent valuation method for estimating willingness to pay for public goods typically adopts a single referendum question format which is statistically inefficient. As an alternative, Cooper, Hanemann and Signorello (2002) propose the 'one-and-one-half bound' (OOHB) format allowing researchers to question respondents about both a lower and higher limit upon project costs, thereby securing substantial statistical efficiency gains. These bounds are presented prior to the elicitation of responses thereby avoiding the negative 'surprise' induced by an unanticipated second question. However, this approach conflicts with the Gibbard-Satterthwaite result that only a single referendum format question is incentive compatible. The OOHB method may... |

| Through a combination of experimental and field analysis, we demonstrate that varying the visible choice set (i.e., set of goods which, at any given point in a valuation exercise, the respondent perceives as being the full extent of purchase options which will be made available in the course of that exercise) strongly affects observed scope. These results challenge the conclusion that contingent values are plagued by embedding and ordering effects, suggesting that such effects can be eliminated when the respondent is completely informed about the entirety of valuation tasks prior to answering the first elicitation question. |
