背景因素和最大价格信息对BDM拍卖支付意愿的影响-三个亚洲国家的实证分析

摘要

本文的研究目的在于分析背景因素和最大价格信息对BDM拍卖支付意愿的影响。为了分析农村居民对饮用水水质改善的支付意愿，本文选取便携式水过滤器为BDM的拍卖物。来自中国、柬埔寨和菲律宾的354名随机样本参与了本研究的实验，其中有一半的样本来自于家里有自来水的家庭，另一半来自于家里没有自来水的家庭。样本再被随机地分成两组：一组样本被告知拍卖物的最高价格信息，另一组样本不被提供拍卖物的最高价格信息。研究结果表明：被提供拍卖物最高价格信息的样本给出的平均支付意愿高于不被提供最高价格信息样本的平均支付意愿，但二者之间没有显著差异。参与者的背景因素(家庭是否有自来水供给)和其他社会经济因素(收入、年龄和教育水平等)对参与者的支付意愿有显著的影响。没有自来水供给的家庭比有自来水供给的家庭对饮用水水质改善有较高的支付意愿；收入较高和受教育水平较高的家庭对饮用水水质改善有较高的需求；菲律宾和柬埔寨的农村居民对便携式水过滤器的需求明显高于中国的农村居民。%The purpose of this study was to measure the effect of maximum price information and contextual fac-tors on people’s bidding behaviors in a controled Becker-DeGroot-Marschak (BDM) experimental auctions. 354 respondents from three Asian countries (China, Cambodia and the Philippines) participated in this study. In each country, both households with piped water connection and households without piped water connection were inves-tigated. The sample in each country was then randomly assigned to two groups: one group was provided with a maximum price of a water filter and the other group was not provided with the maximum price information. The re-sults show that the treatment group with maximum price information had a higher actual wilingness-to-pay than the control group without maximum price information, but they were not significantly different. Our results also indicate that contextual and socioeconomic factors did play a role in participants’ bid results for the water filter.
