Are Valuations from Nonhypothetical Choice Experiments Different from Those of Experimental Auctions?
比较非假设性选择实验和实验拍卖两种方法所测得的消费者支付意愿，发现两者估值存在差异，对偏好诱导方法的选择有参考价值。
Due to the importance of comparability and external validity of results, nonhypothetical experimental methods are increasingly used to elicit consumers’ willingness to pay for various goods. Two of the increasingly popular preference elicitation methods are the nonhypothetical choice experiments and experimental auctions. We conduct experiments to compare willingness to pay estimates elicited from both methods. Our results generally suggest that valuations elicited from experimental auctions can differ from those obtained from nonhypothetical choice experiments.
