Simplified risk analysis in agricultural extension
比较了均值-方差分析、随机占优准则与Hanoch-Levy方法在农业风险评估中的应用，发现Hanoch-Levy准则能缩小风险有效集且推荐结果合理。
Abstract Attention is given to the major methods of assessing risk in order to make choices. The literature frequently reports studies on mean-variance ( E - V ) analysis and stochastic dominance rules. Both of these methods are compared, in an agricultural application, with the approach outlined by Hanoch and Levy. The empirical results suggests that Hanoch and Levy's criterion appear to reduce the size of the risk-efficient set, and that the sets of recommendations from the methods under comparison were consistent. The two recommendations generated by Hanoch and Levy's rule were found to be reasonable for this particular decision process.
