While there is suggestive evidence that regulations may have a stifling effect on innovation, there is as yet no rigorous economic framework to quantify the magnitude of such regulatory effects on innovation and the aggregate economy. This column proposes such a framework tests its implications on data from France. As the framework predicts, regulations do indeed hamper innovation, but the negative effects concern only incremental innovations and are absent for radical innovations.  Overall, regulations are estimated to reduce aggregate innovations by 5%.

For economies to innovate and grow past the COVID-19 crisis, policymakers have to understand the implications of various policies for innovation and economic growth, and take into account how people sort into professions and how potential scientists and innovators respond to policy. This column presents a comprehensive framework to study theoretically and empirically the role of education and R&D policies for boosting innovation and economic growth. It finds that policy tools in both education and R&D are complementary in developing talent, which is the key ingredient to innovation. The best mix of policies depends on how unequal society is and how urgently innovation is needed.

Direct public support for business R&D is common practice in many countries, but evidence on its causal effects has been mixed. This column exploits discontinuity in the assignment mechanism of the first large-scale European R&D grant programme to assess the impact of the policy. The results indicate that direct grants have positive and sizable effects on a wide range of firm-level outcomes suggesting that R&D grants are an effective policy tool.

Dominant companies in the digital market may use merger and acquisitions – especially ‘killer’ or ‘zombie’ acquisitions – and the (under)enforcement of merger control to stifle competition and cement their market dominance. This column analyses acquisition activity by Amazon, Facebook, and Google between 2008 and 2018, and finds that they often targeted very young firms. Because the evolution of young firms is still uncertain, it is difficult for competition authorities to assess the effects of these mergers, especially when the focus is on single acquisitions without considering the overall acquisition strategy.

Numerous empirical studies have shown a decrease in business dynamism in the US and other high-income countries in the last decades. This column investigates the case of the Turkish manufacturing sector. Results indicate that business dynamism in the sector has declined since 2012. Market concentration and exit rates have risen, and new business creation, the labour share in output and economic activities of young firms have fallen. Using an endogenous growth framework, it argues that the inability of follower firms to credibly challenge market leaders is a likely reason, brought on by a lack of access to finance.

Following the Global Crisis, some countries increased expenditures on research and development (R&D) to address secular stagnation. This column investigates how successful this rise in R&D scale was in supporting productivity growth in Japan and other advanced economies. It argues that R&D efficiency has declined in many of these countries in the past decade, compared to the preceding ten years. This suggests that increasing R&D spending is not enough to foster growth, and that countries need to do more to support innovation and collaboration in carefully chosen sectors.

Higher risk perception may suppress demand for a product class and chill R&D investment, or increase the incentive to innovate risk-mitigating technologies. The column uses media coverage of accidents involving CT scanners to investigate the impact on firm innovation. Higher public risk perception increased patent applications and the rate of new product innovation, even without changes in liability or regulation.

The US economy has witnessed a number of striking trends that indicate rising market concentration and a slowdown in business dynamism in recent decades. This column uses a micro-founded model of endogenous firm dynamics to show that a decline in the intensity of knowledge diffusion from frontier firms to laggard ones plays a key role in the observed shifts. It presents new evidence on higher concentration of patenting in the hands of firms with the largest stock that corroborates declining knowledge diffusion in the economy.

Technology diffusion to emerging markets helps share growth potential across countries and lift global living standards. Using a global patent citation dataset, this column estimates the magnitude and impact of international knowledge and technology diffusion, as well as the role that globalisation has played. In emerging markets, knowledge flows have increased innovation and productivity. Competition from emerging markets benefits global innovation.

Digitalisation is transforming human life – from the way we interact with each other to the way we work, relax, and create. R&D within companies is no exception. This column lays out pathways for policymakers to successfully adapt R&D policies to these changes based on three guiding principles: direct policies towards spillovers, make policies technology-neutral, and do not favour superstars over challengers.

International markets can provide exporting firms with more opportunities to generate and introduce innovations and capitalise on their investments relative to purely domestic firms. Using German data, this column demonstrates that exporting firms introduce innovations more frequently than domestic firms and have higher economic gains from their innovations. Trade restrictions such as tariffs can affect a firm’s economic activities in foreign markets and also their R&D and innovation activities.

The European Commission plans to spend about €120 billion on research and innovation under mission-oriented programmes between 2021 and 2027. This column shows that planned spending is small both relative to the total R&D spending of individual EU countries and relative to previous missions. In addition, there is a lack of clarity on how missions will be determined, designed and governed. Experiences in other countries suggest that the Commission should find new ways of increasing funding to missions and increase clarity on the implementation of mission-oriented policies.

Philippe Aghion, of the College de France and LSE, discusses work on merged datasets from the UK – one detailing occupation & wages, the other looking at R&D and investment.

Economists have studied the nexus between labour demand, globalisation, and technology adoption for decades, but quantifying the relative importance of these factors is challenging. Using firm-level data from France, this column proposes a new measure of productivity based on the number of workers in technology-related occupations. It finds large effects of importing, ICT, and R&D on the relative demand for skilled workers through their effects on productivity. Interestingly, the demand for both skilled and unskilled workers rises when firms hire ‘techies’ or engage in offshoring.

Innovative activity is unevenly distributed geographically, with regional characteristics such as global market accessibility or an innovation-promoting policy environment affecting the spatial distribution. Using global data on regional characteristics, regional patenting output, and innovation-promoting policy environments, this column examines the origins of innovation clusters, and particularly the role of R&D tax policy instruments, in attracting innovative firms. It estimates that innovation-promoting R&D tax policy instruments contribute to about one-tenth of the long-term economic growth around the globe.

R&D tax breaks are often offered to businesses to encourage innovation. This column uses evidence from a tax reform in China to study the relationship between tax enforcement and firm innovation. Lower taxes improve both the quantity and quality of firm innovation, and have a bigger impact on those firms that are either financially constrained or those that engage more in tax evasion.

Real exchange rate devaluations are typically seen as a viable development strategy, but the effectiveness of the approach may vary over time and across countries. This column explores this issue by focusing on the microeconomics of firm-level responses to exchange rate fluctuations. Results show varying patterns of responses to fluctuations by region and by import/export orientation. These results highlight the crucial role of a firm’s integration in global value chains.

Economically disadvantaged regions are, arguably by definition, less innovative than advantaged regions. But not all economically disadvantaged areas are the same. This column compares the innovative capacity of economically less-developed areas in North America and Europe, and reveals that less-developed regions in Canada and the US are far more innovative than their European counterparts. Key factors affecting innovation processes include the ability to absorb skilled young labour into the workforce and the types of knowledge flows that are capitalised upon.

Tax incentives to encourage firms to invest in R&D may also encourage firms to fraudulently relabel other expenses as R&D. The column finds that 30% of the increase in reported R&D in response to a Chinese incentive programme was due to relabelling. The size and type of tax break has a large effect on both the level of participation and the incentive to relabel.

US firms have begun shifting R&D investment towards non-traditional destinations such as China, India, and Israel. The column argues that this is a response to a shortage in software and IT-related human capital within the US. When US multinationals are able to import talent or export R&D work, this reinforces US technological leadership. Conversely, politically engineered constraints on this response will undermine the competitiveness of US-based firms.
