A Convex Model of Equilibrium Growth: Theory and Policy Implications
构建了一个技术侧凸性且包含固定要素的均衡增长模型，证明了人均消费长期增长率取决于偏好、技术和政策参数，并指出在自由贸易加税收的均衡中，各国消费和产出增长率不必趋同。
The authors' aim in this paper is to exposit a convex model of equilibrium growth. The model has two features that distinguish it from most other work on the subject: first, the model is convex on the technological side and, second, fixed factors are explicitly included. Existence and characterization results are provided along with some preliminary analyses of taxation and international trade policies. It is shown that the long-run growth rate in per capita consumption depends, in the natural way, on the parameters describing tastes, technology, and policies. It is demonstrated that, in a free-trade equilibrium with taxation, national growth rates of consumption and output need not converge. Copyright 1990 by University of Chicago Press.
