We explore this idea empirically using a panel of industries across twelve OECD countries. We find R&D to be statistically and economically important in both technological catch-up and innovation. Hum...

Many writers have claimed that research and development (R&D) has two ‘faces’. In addition to the conventional role of stimulating innovation, R&D enhances technology transfer by improving the ability of firms to learn about advances in the leading edge (‘absorptive capacity’). In this paper we explore this idea empirically using a panel of industries across twelve OECD countries. We find evide...
