A Decision Theoretic Model of Innovation, Technology Transfer, and Trade
构建了一个动态南北模型，分析创新、技术转让与贸易的互动。研究发现，技术转让使北方无法完全获得研发收益，导致创新率低于全球最优水平；转让率提高会加剧南北劳动力竞争，促使北方企业将劳动力重新配置到研发部门。
We analyse a dynamic North-South model of innovation, technology transfer, and trade. Northern firms conduct R&D using labour which has alternative uses producing in the R&D sector or a nontraded good sector. Since technology transfer prevents the North from fully appropriating benefits of R&D, the optimal rate of innovation for either profit maximizing firms or a utility maximizing Northern planner is less than globally optimal. An increased transfer rate intensifies competition of lower wage Southern workers with Northern workers in production, so profit maximizing Northern firms (irrespective of their number or cooperation in R&D) reallocate labour toward R&D.
