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随机长期优化模型中,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,并提供了估算样本信息期望价值的方法和实证结果。
Abstract 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.
