摘要

我们使用包含植物植被信息的独特数据集估计基于结果的农业环境支付对生物多样性的影响。这些数据包括对瑞士大量随机选择的地块进行了20年跟踪调查的植物物种信息。在我们的估计中,我们采用了基于外源性支付变化的不连续性差异方法,该方法由以下因素触发:(i)瑞士的政策改革导致了实施前不确定的支付大幅增加;(ii)改革的行政门槛,根据植物质量定义支付资格。我们发现,基于结果的补贴的增加导致改革前几乎有资格获得补贴的地块的生物多样性增加,而已经满足资格标准的地块则没有。我们的研究结果对基于结果的支付的设计具有重要意义。

The effect of result-based agri-environmental payments on biodiversity: Evidence from Switzerland

The effect of result-based agri-environmental payments on biodiversity: Evidence from Switzerland

We estimate the effects of result-based agri-environmental payments on biodiversity using a unique dataset containing information about plant vegetation. The data include information on surveyed plant species for a large number of randomly selected plots followed over a period of 20 years in Switzerland. In our estimation, we utilize a difference-in-discontinuities approach based on exogenous variation in payments triggered by (i) a policy reform in Switzerland that led to a considerable increase in payments that was uncertain prior to the implementation and (ii) an administrative threshold of reform that defines eligibility for payment depending on the botanical quality. We find that the increase in result-based payments led to an increase in the biodiversity of plots that were almost eligible for the payments before the reform but not for plots that already satisfied the eligibility criteria. Our findings have important implications for the design of result-based payments.

期刊介绍: The American Journal of Agricultural Economics provides a forum for creative and scholarly work on the economics of agriculture and food, natural resources and the environment, and rural and community development throughout the world. Papers should relate to one of these areas, should have a problem orientation, and should demonstrate originality and innovation in analysis, methods, or application. Analyses of problems pertinent to research, extension, and teaching are equally encouraged, as is interdisciplinary research with a significant economic component. Review articles that offer a comprehensive and insightful survey of a relevant subject, consistent with the scope of the Journal as discussed above, will also be considered. All articles published, regardless of their nature, will be held to the same set of scholarly standards.
