How Choice Experiment Design Affects Estimated Valuation of Use of Gestation Crates
通过六种不同属性数量的选择实验设计，研究设计维度和消费者推断如何影响对猪肉生产中妊娠栏使用的支付意愿和福利估计，提醒研究者单一设计可能导致结果不稳健。
Abstract This study utilises a split‐sample experimental approach where six different choice experiment designs that vary in the number of attributes are used to control for the effects of design dimensions and consumer inferences in assessing consumer demand. Our application is in the use of gestation stalls (crates) in pork production. Our findings suggest that effects of both the mixture of attributes included in the design and consumer inferences on the specific attributes presented in experiments influence estimated willingness‐to‐pay and consumer welfare. Implications are that when researchers limit their studies to the use of a unique choice experiment design, resulting willingness‐to‐pay estimates might not be robust to different specifications.
