We investigate how a country’s absorptive capacity and relative backwardness affect the impact of international R&D spillovers on domestic Total Factor Productivity (TFP). To account for nonlinearities, we adopt a Panel Smooth Transition Regression approach, where a country’s TFP elasticity to the foreign R&D stock is allowed to change smoothly across various identified extreme values, and the change is related to observable transition variables: human capital (capturing the country’s absorptive capacity) and relative backwardness. The results suggest that absorptive capacity is positively associated with international R&D spillovers. In contrast with previous results, relative backwardness is instead found to have a negative and significant impact on international knowledge spillovers.

Abstract
We investigate how a country’s absorptive capacity and relative backwardness affect the impact of international R&D spillovers on domestic Total Factor Productivity (TFP). To account for nonlinearities, we adopt a Panel Smooth Transition Regression approach, where a country’s TFP elasticity to the foreign R&D stock is allowed to change smoothly across various identified extreme values, and the change is related to observable transition variables: human capital (capturing the country’s absorptive capacity) and relative backwardness. The results suggest that absorptive capacity is positively associated with international R&D spillovers. In contrast with previous results, relative backwardness is instead found to have a negative and significant impact on international knowledge spillovers.File | Dimensione | Formato | |
