摘要

估值客户施加的影响所产生的估值偏差,一直是影响全球估值客观性、有效性和效用的一个令人关注的问题。客户导致的估值偏差对斐济等小岛屿发展中经济体尤其令人担忧,在这些经济体中,全球估值实践标准的采用和实施仍处于起步阶段。本研究采用问卷调查和行为实验来检验斐济客户对估价影响的存在和性质。研究发现,大多数评估师都知道在他们的专业工作中存在客户引起的偏见。此外,评估师表达了强烈的意见,即客户在委托评估师之前确实通过要求提供指示性数据来进行“意见购物”,并且客户也将信息作为影响估值结果的杠杆。最后,分析行为实验反应的逻辑回归模型的结果表明,客户规模和客户寻求的价值调整幅度在解释估价师是否修改其估值的决定方面都没有统计学意义。

An Empirical Study on Client-induced Valuation Bias - Evidence from Fiji
Valuation bias stemming from the influence exerted by valuation clienteles continues to be a subject of concern affecting the objectivity, validity and utility of valuations globally. Client-induced valuation bias is of particular concern for small island developing economies like Fiji, where the adoption and implementation of global valuation practice standards is still in its infancy. This study employs a survey questionnaire and a behavioural experiment to examine the existence and nature of client influence on valuations in Fiji. The study finds that most valuers are knowledgeable of the existence of client-induced bias in their professional line of work. Furthermore, the valuers express strong opinions that clients do engage in ‘opinion shopping’ by requesting indicative figures prior to commissioning a valuer, and that clients also use information as leverage to influence valuation outcomes. Lastly, the result of the logistic regression model analysing the behavioural experiment responses suggests that neither client size nor magnitude of value adjustment sought by the client are statistically significant in explaining the valuer’s decision on whether or not to revise their valuations.
