Around the world, growth has yet to recover to its pre-Global Crisis trend. This column uses the crisis as a quasi-natural experiment to test the endogenous growth hypothesis, which suggests that output has not recovered because the crisis affected the rate of technological progress. Firms that preferred a bank that was more severely affected by the crisis experienced a large fall in R&D investment and a persistent fall in output in subsequent years. This suggests a direct link between R&D and future productivity, as predicted by endogenous growth models.

Research and development investment is a major driving force behind innovation and economic growth. Policy measures that aim to boost innovation activities attempt to improve incentives for these investments. This column reports on recent research showing that a firm’s financial strength is strongly correlated with the firm’s expected return to research and development, and therefore has a substantial impact on its research and development investment decision.

Although healthcare innovation can make treatment cheaper, it can also make policy decisions more difficult by introducing new, better but more expensive technologies. This column argues that, unlike other technologies, healthcare technology is intermediated by insurance mechanisms, both private and public. Although health insurance coverage incentivises expenditure on innovation, it does not seem to heighten technology adoption, a challenge to the idea that innovation increases healthcare costs. Indeed, evidence suggests that technology diffusion is limited by other institutional barriers.

With foreign ownership of domestic companies becoming increasingly common, questions are mounting as to the consequences. One area of concern is the effect on research and development. This column presents new evidence from Sweden, where flagship firms such as Volvo and Saab are now foreign owned, that it hopes will reassure policymakers.

Why do local policymakers fight so hard to attract research and development labs to their area? This column provides a possible explanation. Using patent data, it finds a strong link between R&D and growth caused by knowledge spillovers between firms.

How can poor countries stop playing catch up? The question continues to puzzle economists. This column argues that the innovative and productive activities of domestic firms in emerging markets are inhibited by financial frictions. Financial reforms will be most effective if they target the vulnerable small and young domestic firms and those in the service sector.
