如果没有市场结果可供比较，就需要进行内部一致性检验，特别是累加检验，以确保可信度。经过测试，或有估值失败了。支持者发现调查测试做得很差。据作者所知，没有任何调查通过这些测试。“嵌入效应”是支付意愿反应的相似性，理论表明（有时要求）是不同的。这个问题早就被认识到了，但一直没有解决。作者的结论是，目前的方法不适合损害评估或效益-成本分析。他们认为，问题在于缺乏偏好，而不是调查方法的缺陷，因此不太可能改善。
Without market outcomes for comparison, internal consistency tests, particularly adding-up tests, are needed for credibility. When tested, contingent valuation has failed. Proponents find surveys tested poorly done. To the authors' knowledge, no survey has passed these tests. The 'embedding effect' is the similarity of willingness-to-pay responses that theory suggests (and sometimes requires) be different. This problem has long been recognized but not solved. The authors conclude that current methods are not suitable for damage assessment or benefit-cost analysis. They believe the problems come from an absence of preferences, not a flaw in survey methodology, making improvement unlikely.
