摘要

在具有消费电子产品的Lucas模型中，我们研究了要素替代对长期均衡的影响。长期增长率并不取决于替代的弹性。然而，如果实物资本与有效劳动力的基线比率低于（高于）其稳态值，则要素替代的弹性与收敛速度之间存在负（正）关系。

Factor substitution, long-run equilibrium, and convergence speed in the Lucas model

We study the effect of factor substitution on long-run equilibrium in the Lucas model with CES production. The long-run growth rate does not depend on the elasticity of substitution. However, there is a negative (positive) relationship between the elasticity of factor substitution and the convergence speed if the baseline ratio of physical capital to effective labor is below (above) its steady-state value.

期刊介绍： Many economists today are concerned by the proliferation of journals and the concomitant labyrinth of research to be conquered in order to reach the specific information they require. To combat this tendency, Economics Letters has been conceived and designed outside the realm of the traditional economics journal. As a Letters Journal, it consists of concise communications (letters) that provide a means of rapid and efficient dissemination of new results, models and methods in all fields of economic research.
