由浙江大学中国农村发展研究院、公共管理学院易福金教授与其团队成员胡鸣宇,南京农业大学经济管理学院教授周宏合作完成的论文“Stepping stone or stumbling block: Anchoring effect of crop insurance subsidies”在国际农经领域知名期刊Canadian Journal of Agricultural Economics在线发表。

英文摘要
This study examines how the anchoring effect created by long-term high premium subsidies leads to irrational crop insurance purchasing behavior among farmers. Using a randomized controlled trial, we show that the insurance experience of low premium generates an intrinsic anchoring effect and inhibits farmers' willingness to pay for new crop insurance through two main channels: price and perception. At the same time, farmers with small crop scale, limited disaster experience, and a diverse income structure are more susceptible to intrinsic anchoring impacts. In addition, the results suggest that the anchoring effect of high premium subsidies on farmers is difficult to change. This distortion of value perceptions counteracts the potential external anchoring effect of favorable information and further inhibits farmers' willingness to pay.
中文摘要
本研究探讨了农民在长期高强度保费补贴政策下,会因为锚定效应而扭曲农户的农业保险购买行为。通过随机对照实验,我们发现农户低价保险的购买经历会产生内在锚定效应,并通过价格和感知两个主要渠道抑制其购买更高保障水平的农业保险的意愿。尤其是,以生产规模小、灾害经验有限、收入结构多样化为特征农户往往表现为保险需求弹性较高,而这类群体更易受到内在锚定效应的影响。此外,研究结果表明,高额补贴对农民形成的锚定效应难以改变。这种对农业保险价值认知的扭曲抵消了其他有利信息可能产生的外部锚定效应,并进一步抑制了农民的支付意愿。
本研究是该团队在农业保险领域破解小农户的农业保险需求困境方面的重要成果之一。本研究得到了NSFC-BMGF联合农业研究项目(72261147758)、国家自然科学基金一般项目(72273065)和国家社会科学基金重大项目(23&ZD108)的资助。
