Abstract: | Using panel data from 16 Organization for Economic Cooperation and Development (OECD) countries for the period 1981–2000, we examine the significance of international knowledge spillovers through inward and outward foreign direct investment (FDI), intermediate goods imports, and a disembodied direct channel. Knowledge spillovers through the disembodied direct channel are approximated by using a measure of technological proximity and patent citations between countries. Using estimation models that reflect recent developments in non-stationary panel data econometrics, we show that international knowledge spillovers through inward FDI and the disembodied direct channel are significant and robust. In contrast, outward FDI and imports of intermediate goods are not conducive to international knowledge spillovers. |
