Foreign Reserve Adequacy In Sub-Saharan Africa

The empirical analysis in "International R&D Spillovers" (Coe and Helpman, 1995) is first revisited by applying modern panel cointegration estimation techniques to an expanded data set that the authors have constructed for the purpose of this study. The new estimates confirm the key results reported in Coe and Helpman about the impact of domestic and foreign R&D capital stocks on TFP. In addition, they show that domestic and foreign R&D capital stocks have measurable impacts on TFP even after controlling for the impact of human capital.
