Challenges of Conducting Contingent Valuation Studies in Developing Countries
基于在五个发展中国家对转基因水稻进行实地条件价值评估的经验，以及一项对农业和应用经济学家的调查，总结了开展此类研究时在人员培训、参与者招募、抽样、补偿、调查实施、诱导方法、识字率和安全等方面面临的挑战。
We review the experiences and challenges that researchers can face when conducting contingent valuation studies in developing countries. We discuss these challenges based on our own experiences of conducting field‐contingent valuation studies about genetically modified rice in five developing countries that represent different regions of the world and diverse cultures; we also base our discussion on results from a survey we conducted of agricultural and applied economists regarding their own experiences. The issues covered include the selection and training of local personnel, the recruitment of participants, sampling challenges, participants' compensation, survey methods and implementation, elicitation methods, the literacy rate of the population, and security/safety issues in developing countries. We also discuss the implications of our findings to other well‐established stated‐preference methods such as choice experiments.
