Our paper decomposes knowledge-diffusing trade flows and estimates their impacts separately. Overall, trade generates positive knowledge spillovers, but the effects of intra-industry trade are ambiguous. With regard to sectoral import penetration, we find that potential positive spillovers are...

Reexamining foreign direct investment (FDI) as a potential channel for knowledge diffusion -- based on industry data from seventeen OECD countries during the period 1973-2000 -- we find that FDI-receiving countries benefit strongly from FDI-related knowledge spillovers. We do not find evidence...

This paper presents the stylized facts of open source software innovation and provides empirical evidence on the impact of increased competition by OSS on the innovative activity in the software industry. Furthermore, we introduce a simple formal model that captures the innovation impact of OSS...

This paper investigates the productivity effects of inward and outward foreign direct investment using industry and country level data for 17 OECD countries. The paper relates to a large recent literature on productivity spillovers from inward FDI, however, we also consider the relationship...
