Multiproduct Technology and Market Structure
综述了多产品产业的技术决定因素，提出了一个统一框架以进一步发展理论，对研究多产品竞争和自然垄断的经济学者有参考价值。
A recent line of research has exposed some technological determinants of the structure of industries that produce more than one good. The analyses of both multiproduct perfect competition and natural monopoly require a generalized notion of average cost and, in addition, several newly identified technological characteristics pertinent only to joint production. This paper provides an overview of these new results, and suggests a unifying framework in which the theory can be further developed.
