Innovation, Imitation, and Intellectual Property Rights
构建动态一般均衡模型，分析南北国家间知识产权执法对福利的影响，分解为贸易条件、生产结构、产品种类和消费跨期配置四个渠道，并逐步引入内生创新率和外国直接投资。
The debate between the North and the South about the enforcement of intellectual property rights is examined within a dynamic general equilibrium framework in which the North invents new products and the South imitates them. A welfare evaluation of a policy of tighter intellectual property rights is provided by decomposing its response into four items: (1) terms of trade; (2) production composition; (3) available products; and (4) intertemporal allocation of consumption The paper proceeds in stages. It begins with an exogenous rate of innovation in order to focus on the first two elements. The following two components are added by endogenizing the rate of innovation. Finally, foreign direct investment is added to the model. Copyright 1993 by The Econometric Society.
