Technology diffusion and global welfare effects: Imitative R&D vs. South-bound FDI


Author Info

  • Lin, Hwan C.


A country in question is positioned in the middle of a global technology race. To shorten its technology gap with the forerunner (North), this middle country must invest in imitative R&D. To exploit cheap labor in the technological laggard (South), it also must invest in South-bound FDI. A dynamic general-equilibrium model of three countries (North, Middle, South) is set up to numerically analyze how the Middle's refraining South-bound FDI affects international technology diffusion, international wage gaps, and international welfare. The Middle always finds a need to socially optimize investing balance between imitative R&D and South-bound FDI, while the South is instead in favor of as much South-bound FDI as possible. Interestingly, the North may, or may not, align with the Middle's tightening South-bound FDI, depending on how fast the Northern product innovation can proceed over time. Both transitional dynamics and the steady-state equilibrium are computed.
