A Decision Theoretic Model of Innovation, Technology Transfer, and Trade.

The authors analyze a dynamic North-South model of innovation, technology transfer, and trade. Northern firms conduct R&D using labor, which has alternative uses producing in the R&D sector or a nontraded good sector. Since technology trans fer prevents the North from fully appropriating benefits of R&D, the optimal rate of innovation for either profit-maximizing firms or a ut ility-maximizing northern planner is less than globally optimal. An i nceased transfer rate intensifies competition of lower wage southern workers with northern workers in production, so profit-maximizing Nor thern firms reallocate labor toward R&D.
