Investment in research and development (R&D) affects a country's total factor productivity. Recently new theories of … total factor productivity of its trade partners. Following these theoretical developments we estimate the effects of a … country's R&D capital stock and the R&D capital stocks of its trade partners on the country's total factor productivity. We …

&D investment: (1) Are there diminishing returns to inventive activities? (2) What is the relationship between R&D and productivity … output and precise measurement of the inputs to the inventive process. Patent counts are often considered as a measure of … between R&D expenditures and growth of output or total factor productivity. The relation is pervasive, though the magnitudes …

that their functional form of how foreign R&D affects domestic productivity via imports is probably incorrect. We provide …

effect of spillovers on research productivity of firms exceeds the structural effect because it includes an active learning …This paper explores the implications of a simple model of learning and innovation by firms. In this model R … expenditures and internal research expenditures. The findings are consistent with the view that learning expenditures transmit the …

We investigate these phenomena further by examining the relationship between plant-level productivity and firm …-level R&D. We find that (1) the productivity-enhancing effects of parent firm R&D are diminished by geographic distance from …
