英文文献：How Should We Value Agricultural Insurance Contracts-农业保险合同的价值是什么?本文认为，现有的农业保险估值模型存在局限性，要么是由于它们不是对保险合同中不可分散风险进行定价的完全均衡模型，要么是由于它们假定了与农业保险的大多数应用不一致的完全市场

英文文献摘要：
We argue that existing agricultural insurance valuation models are limited either because they are not complete equilibrium models that price the non-diversifiable risk involved in issuing insurance contracts, or they assume complete markets which appears at odds with most applications of agricultural insurance. We also propose two new incomplete market models and derive an insurance valuation formula for each under the assumption of constant relative risk aversion preferences and lognormally distributed random variables. The two models differ in the way they treat trade in insurance contracts, with one model allowing insurers and insureds to trade freely on a liquid secondary market, while the other requires insurance firms to act as brokers between insureds (farmers) and the capital market (those who bear the non-diversifiable risk). The two models lead to different valuation formulas and several interesting insights are obtained by comparing our valuation formulas with those used in the existing literature.

本文还提出了两个新的不完全市场模型，并推导了在相对风险厌恶偏好不变和对数正态分布随机变量假设下的保险估值公式。两个模型的方式上有所区别对待贸易保险合同,与一个模型允许保险公司和被保险人液体二级市场上自由交易,而其他要求保险公司之间充当经纪人投保(农民)和资本市场(那些承担non-diversifiable风险)。这两个模型导致了不同的估值公式，通过比较我们的估值公式和现有文献中使用的公式，我们得到了一些有趣的见解。
