消费者愿意为环保认证的木材产品支付(WTP)价格溢价经常使用指定的偏好方法进行估计。文献中报告的认证木材产品相对于非认证选项的WTP溢价估计在1.0%到39.3%之间。本文描述了一种Meta分析方法，用于通过检查来自世界各地的19项不同研究的数据来确定与WTP价格溢价估计相关的关键因素。贝叶斯层次模型的结果表明，经常购买的木制品和基价较低的木制品往往获得较高的百分比溢价。调查管理方法也是影响WTP估计差异的一个具有统计学意义的因素。结果表明，与条件估值方法相比，联合分析导致了对认证木材产品的夸大WTP估计。据报道，WTP的估计近年来有所增加。提出了减少认证木制品WTP估计误差、提高实验研究有效性的建议。(C)2012年，Umea瑞典农业科学大学森林经济系。由Elsevier GmbH出版。版权所有。
Consumers' willingness to pay (WTP) price premiums for environmentally certified wood products has been frequently estimated using stated preference methods. Estimates of WTP premiums for certified wood products over non-certified options reported in the literature range from 1.0% to 39.3%. This paper describes a meta-analysis used to determine the key factors associated with WTP price premium estimates by examining data from 19 different studies conducted around the world. Results of Bayesian hierarchical models show that frequently purchased wood products and wood products with lower base prices tend to capture higher percentage premiums. Survey administration method was also a statistically significant factor influencing variations in WTP estimates. Results show that conjoint analysis elicited inflated WTP estimates toward certified wood products compared with contingent valuation methods. Reported WTP estimates have increased in recent years. Recommendations to reduce the error of WTP estimates toward certified wood products and improve the validity of experimental studies are provided.
