This paper utilizes data from a split-sample discrete choice experiment to investigate the impact of including an employment attribute on stated preferences for protecting the coastal zone of Arctic Norway. The econometric analysis investigates how its inclusion affects attention to other choice experiment dimensions, and how welfare measures vary between the two subsamples and across models that control for attribute non-attendance versus models that do not. We find that the employment attribute has a relatively high attendance rate and that its inclusion does not appear to decrease attention to other attributes of interest. The impact of the added attribute on the part-worth estimates for environmental attributes is mixed. However, similar to prior research, we find that controlling for attribute non-attendance tends to yield lower welfare estimates. Lastly, our analysis indicates somewhat higher attention to the cost attribute than many previous studies.

环境离散选择实验中的不参与属性：包括就业属性的影响

本文利用来自拆分样本离散选择实验的数据来研究包括就业属性对保护挪威北极沿海地区的既定偏好的影响。计量经济学分析调查了它的包含如何影响对其他选择实验维度的关注，以及福利度量如何在两个子样本之间以及在控制属性不出席的模型与不出席的模型之间变化。我们发现就业属性具有相对较高的出勤率，并且它的包含似乎并没有减少对其他感兴趣属性的关注。添加的属性对环境属性的部分价值估计的影响是混合的。然而，与先前的研究相似，我们发现控制属性缺勤往往会产生较低的福利估计。最后，我们的分析表明对成本属性的关注比以前的许多研究要高。
