Risk Analysis with Single‐Index Portfolio Models: An Application to Farm Planning
改编了Sharpe的单指数投资组合模型和分离定理，用于农场多样化问题，开发了基于单指数参数的风险度量方法，适用于微机和手持计算器的农场风险规划。
Abstract Sharpe's 1963 single‐index portfolio model, the separation theorem, and a solution method suggested by Elton, Gruber, and Padberg are adapted in this paper to the farm diversification problem. The objectives are to develop risk measures, based on single‐index parameters and computationally simple methods for farm risk planning, that are suitable for microcomputers and modern hand‐held calculators. The intent is to produce a normative model with possible extension applications.
