Rethinking the Product Portfolio: A Generalized Investment Model
基于决定产品盈利能力和风险的经济因素，构建了一个广义金融/产品组合理论模型，用于企业的产品投资决策。该模型能区分每个产品的市场相关风险收益与企业特定风险收益，并给出了两个假设性示例和管理启示。
A generalized financial/product portfolio theory is developed, based on the underlying economic factors determining product profitability and risk, for applications involving the firm's product investment decisions. The model developed provides a means for differentiating market related risk and return from firm specific risk and return for each product. Two hypothetical illustrations of the model are described and the managerial implications are discussed.
