在农村发展中国家或收入非常低的情况下进行公开优惠估价研究时，一个令人关切的问题是使用货币支付意愿估计数。在现金收入极低、很大一部分人口不从事有薪劳动、货物或服务的交换通过易货或工作交换扩大的情况下，货币的作用可能不同于城市发达环境中的货币作用。因此，当与其他交换媒介相比时，使用货币支付的能力可能会受到损害并向下偏移。认识到这一点，一些研究使用假设的劳动力缴款作为支付工具，一个共同的发现是，家庭往往更愿意贡献劳动力而不是金钱。在本文中，我们提出了一个分裂的样本DCE的结果，使用金钱和劳动力的贡献作为支付工具，改善饮用水质量干丹省，柬埔寨。我们发现支付工具之间的属性不出勤，属性的边际效用或派生的福利值方面的差异不大。我们认为，这为在农村发展中地区使用支付意愿提供了支持，那里有正常运作的劳动力市场。
A concern when conducting stated preference valuation studies in rural developing or very low income contexts is the use of monetary willingness to pay (WTP) estimates. In circumstances where cash incomes are extremely low, a significant proportion of the population are not engaged in waged labour and the exchange of goods or services is augmented through barter or work exchange, the role of money is likely to be different from that within an urban developed setting. As such, ability to pay using money may be impaired and downwardly biased when compared with other mediums of exchange. In recognition of this several studies have used hypothetical labour contributions as payment vehicles and a common finding is that households are more often willing to contribute labour than they are money. In this paper we present the results of a split sample DCE using money and labour contributions as payment vehicles for improved drinking water quality in Kandal Province, Cambodia. We find little differences between the payment vehicles in terms of attribute non-attendance, marginal utilities of attributes or derived welfare values. We argue that this provides support for the use of WTP in rural developing areas where there are functioning labour markets.
