Abstract

Abstract The use of stated preference methods with monetary payments in developing countries can be problematic as barter and paying with labor are common in rural areas. In response, a growing number of stated preference studies explore using monetary and nonmonetary payment options. We contribute to this literature by exploring the impact of monetary vs. labor payment options on values elicited from choice experiment studies conducted in rural developing country settings. We also contribute to the literature by comparing data-gathering methods, specifically individual surveys vs. group information sessions. Our application is the restoration of an ancient irrigation system known as cascading tank systems in Sri Lanka. We conduct a choice experiment to understand the willingness to pay/willingness to contribute of rural households to restore these irrigation systems. We find that in the individual survey setting, there are no significant differences between monetary and labor payments. We also find that there is no difference between the group and individual survey settings for the monetary payment treatment. For the labor payment treatment, the group setting results in a positive payment coefficient for the labor payment attribute. This highlights that labor payments should be used cautiously in group evaluation settings.
从恢复古代灌溉系统中评估生态系统服务:选择实验中劳动力与货币支付的比较应用
摘要发展中国家在货币支付中使用规定的优惠方法可能会产生问题,因为易货和用劳动力支付在农村地区很常见。作为回应,越来越多的既定偏好研究探索使用货币和非货币支付选项。我们通过探索货币与劳动力支付选项对在发展中国家农村环境中进行的选择实验研究得出的价值观的影响,为这篇文献做出了贡献。我们还通过比较数据收集方法,特别是个人调查和小组信息会议,对文献做出了贡献。我们的应用是修复斯里兰卡一个被称为级联水箱系统的古老灌溉系统。我们进行了一项选择实验,以了解农村家庭为恢复这些灌溉系统的支付意愿/贡献意愿。我们发现,在个人调查环境中,货币和劳动力支付之间没有显著差异。我们还发现,在货币支付待遇方面,团体和个人调查设置之间没有差异。对于劳务支付处理,组设置会导致劳务支付属性的支付系数为正。这突出表明,在组评估设置中应谨慎使用劳动报酬。
