Eliciting and Utilizing Willingness to Pay: Evidence from Field Trials in Northern Ghana
研究利用BDM机制估计加纳北部居民对清洁饮水技术的支付意愿，并与标准方法比较，展示其在需求估计、异质性处理效应和价格筛选效应方面的应用。
We utilize the Becker-DeGroot-Marschak (1964) mechanism to estimate the willingness to pay for clean drinking water technology in northern Ghana. The BDM mechanism has attractive properties for empirical research, allowing us to directly estimate demand, compute heterogeneous treatment effects, and study the screening and causal effects of prices with minor modifications to a standard field experiment setting. We demonstrate the implementation of BDM along these three dimensions, compare it to the standard take-it-or-leave it method for eliciting willingness to pay, and discuss practical issues for implementing the mechanism in true field settings.
