Dynamics of International R&D Spillovers
January 01, 2004
The authors empirically examine reports of positive and equivalent research and development (R&D) spillovers across groups of countries by extending both the time span and the coverage of R&D activities in the data set. Findings indicate that the elasticity of total factor productivity with respect to domestic and foreign R&D stocks is extremely heterogeneous across countries and that data cannot be pooled.
