Value of information on crop response function to soil salinity in a farm-level optimization model
研究了在单个农场利用咸水的长期随机优化模型中，获取作物（马铃薯）对土壤盐分响应函数的额外信息的经济价值，并提供了估计样本信息期望值的方法。
The study investigates the value of additional information on the response function to soil salinity of a given crop (potatoes), with regard to a stochastic long-run optimization model for utilization of saline water in a single-farm framework.The analysis provides a conceptual and methodological framework for investigating the expected value of sample information (EVSI), as well as an efficient tool for empirical application.Although a few approximations have been used, the results provide an estimate of EVSI and indicate the need for additional information.
