本文考虑了一个两部门经济增长模型，其中“劳动力增加”的部门间外部效应源于总资本存量。结果表明，均衡平衡的增长路径与非平凡的劳动力分配计划成为可用。一组充分条件的存在多个平衡增长射线提供和他们的确定性属性，然后特征。最后，检查参数化的C.E.S.经济说明了在多重性问题中，非单一价值对替代弹性的核心作用。
This article considers a two-sector model of economic growth with “labour-augmenting” intersectoral external effects stemming from the aggregate capital stock. It is shown that equilibrium balanced growth paths with a non-trivial labour allocation scheme become available. A set of sufficient conditions for the existence of multiple equilibrium growth rays is provided and their determinacy properties are then characterised. Finally, examination of a parameterised C.E.S. economy illustrates the central role of non-unitary values for the elasticity of substitution in the multiplicity issue.
