使用多项选择模型分析美国内布拉斯加盆地农民同时选择耕作、轮作和土壤检测等管理实践的决定因素，并评估不同组合的经济与环境影响。
Abstract Farmers' management practices can have a significant effect on agricultural pollution. Past research has analyzed factors influencing adoption of a single management practice. But often adoption decisions about many practices are made simultaneously, which suggests use of a polychotomous‐choice model to analyze decisions. Such a model is applied to the choice of alternative management practices on cropland in the Central Nebraska Basin and controlled for self‐selection and the interaction between alternative practices. The results of the choice model are used to estimate the economic and environmental effects of adopting alternative combinations of management practices.
