【摘要】 为了给延边地区农业风险管理研究提供重要参数,本文估计了延边地区玉米种植农户的相对风险回避系数。分析中使用的数据通过2阶段假设性问题构成的问卷调查获取,在效用函数及对相对风险回避系数分布的对数正态的假设前提下,对目标函数进行最大似然估计得到参数的估计值。结果得出:延边地区玉米农户相对风险回避系数平均为9.15,标准差为16.8。更多还原

【Abstract】 This paper estimated the relative risk aversion coefficients of corn farmers in Yanbian.Two hypothetical situations were designed and two-stage questionnaires were conducted for each situation.A utility function that has constant relative risk aversion was used,and it was assumed that the relative risk aversion coefficients followed a log-normal distribution.As a result,the mean and standard deviation of the relative risk aversion coefficients of corn farmers was 9.15 and 16.8,respectively.更多还原
