The Economics of Fish Consumption Advisories: Insights from Revealed and Stated Preference Data
提出一种联合估计技术，利用显示偏好和陈述偏好数据，评估鱼类消费建议对垂钓者效用的影响，并以福克斯河/格林湾为例进行实证分析。
<i>Measuring how fish consumption advisories affect angler’s utility has proven difficult. Relying on stated preference (SP) data is problematic because of hypothetical bias. Revealed preference (RP) data benefits from using actual behavior; however, co-linearity often makes it difficult to model the array of advisory severity levels across different species and catch rates. The array of advisories also makes traditional joint estimation impractical. This paper describes an alternative joint estimation technique, based on an index of SP parameter, that we used for estimating the effect of fish consumption advisories on the Fox River/Green Bay.</i>
