英文文献摘要：
Using a series of hurdle choice models, this study considers both nay-saying and yeah-saying to alternatives offered in a conjoint experiment. These behaviors are characterized by respondents persistently choosing the no-choice alternative or choosing at least one of the non-empty options offered in a survey. Results show that jointly consider nay-saying and yeah-saying in a two-hurdle model drastically improves model fit; welfare implications based on hurdle models are also different from those based on models without hurdle specification.

使用一系列障碍选择模型，本研究考虑对联合实验中提供的选项说“不”和“是”。这些行为的特征是被调查者持续地选择没有选择的选项，或者选择调查中提供的至少一个非空选项。结果表明，在双栏模型中同时考虑说“不”和“说”可以显著提高模型的拟合;基于跨栏模型的福利含义也不同于基于没有跨栏说明的模型的福利含义。
