本研究报告的实验结果，旨在引起，在一个受控的实验室环境中，假设的和真实的愿意支付的环境教育方案，使用开放式的问题格式。通过保持良好的和问题的格式恒定的治疗，实验克服了最近报道的实验结果的缺点，提供了一个干净的测试假设偏差在开放式估值。在发现假设价值和真实的价值之间存在统计学上的显著差异之后，接下来的问题是，假设估值是否仍然可以提供关于个人真实的估值的有用统计信息。这个问题，这可能是关键问题，在目前的状态下，围绕或有价值评估方法的辩论，是肯定的回答，在这项研究中。
This study reports the results of experiments designed to elicit, within a controlled laboratory environment, hypothetical and real willingness to pay for an environmental educational programme using the open-ended question format. By maintaining both the good and the question format constant across the treatments, the experiments overcome the shortcomings of recently reported experimental results, providing a clean test for hypothetical bias in open-ended valuations. Having found a statistically significant difference between the hypothetical and real values, the question of whether hypothetical valuations may nonetheless provide useful statistical information concerning individuals' real valuations is turned to. This question, which is perhaps the key question in the current state of the debate surrounding the contingent valuation method, is answered affirmatively in this study.
