This study offers a Choice Experiment (CE) analysis of geographical scope effects. About 500 stated preference surveys were conducted to estimate willingness-to-pay (WTP) for nature protection in the Netherlands and the Caribbean Netherlands which became part of the Netherlands’ constitution just before the survey, providing a unique policy setting. Two version of the CE were implemented with a narrow or a broader geographical scope. Estimation of error correction mixed logit models resulted in the following main insights. First, the hypothesis of scope invariance is rejected since expanding the geographical scope influenced WTP values for nature protection. As an illustration, policies of preventing a degradation of nature have an average WTP of about €20 in the experiment with the smaller geographical scope, while this WTP is not significantly different from zero in the experiment with the more extensive scope. Second, evidence of scope sensitivity of WTP to the levels of nature protection is mixed, and depends on the geographical scope of the CE. We find a sizable WTP for protection of nature in Caribbean Netherlands among citizens of the mainland of the Netherlands, which supports the observed sizable funding of the Dutch government for nature management in the Caribbean Netherlands.

地理范围和为自然保护付费的意愿

本研究提供了地理范围效应的选择实验(CE)分析。进行了约500项陈述的偏好调查,以估算荷兰和加勒比海地区自然保护的支付意愿(WTP),这在调查之前已成为荷兰宪法的一部分,提供了独特的政策设置。CE的两个版本是在狭窄或广泛的地理范围内实施的。纠错混合logit模型的估计得出以下主要见解。首先,范围不变性的假设被拒绝了,因为扩大了地理范围影响了自然保护的WTP值。例如,在较小地理范围的实验中,防止自然退化的政策的平均WTP约为20欧元,而该WTP在更大范围内的实验中与零没有显着差异。其次,WTP对自然保护水平的范围敏感性的证据是混杂的,并且取决于CE的地理范围。我们在荷兰大陆公民中发现了相当大的WTP,用于保护荷兰加勒比海地区的自然,这支持了荷兰政府观察到的可观资金,用于荷兰加勒比海地区的自然管理。
