Attribute and Safety Perceptions in a Double‐Hurdle Model of Shellfish Consumption
基于美国东南部成年人调查数据，用双重门槛模型分析健康风险等属性感知如何影响贝类消费的参与和数量决策，发现感知对两个决策都有影响，但改善检查计划对需求影响有限。
Abstract Individuals' perceptions of food product attributes such as safety may influence decisions about whether to consume and how much to consume. Survey data from southeastern U.S. adults were used in a double‐hurdle model to evaluate effects of health risk and other attribute perceptions on shellfish demand. Results indicate that attribute perceptions were important in both participation and consumption decisions. However, responses to new health risk information were not the same for each decision. Findings suggest that efforts to reduce shellfish health risks with an improved U.S. inspection program may have little influence on existing shellfish demand.
