Understanding how taxation influences innovation is of central importance to create investment incentives for R&D, yet our knowledge remains limited due to a lack of data, especially covering a long period of time. This column uses newly constructed datasets from the 20th century to examine the effects of both personal and corporate income taxation on inventors, as well as on firms that do R&D. It finds consistently negative effects of high taxes on innovation over time as well as on individual inventors and firms.

One consequence of the last decades of globalisation is that, thanks to multinational firms, goods are increasingly being produced far from where ideas are created. Using general equilibrium modelling, this column analyses the welfare and distributional effects of the recent wave of protectionism. Central to the results is the flexibility that multinational firms have in locating their innovation and production activities around the globe.

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.

Some economists argue that corruption can contribute to economic growth by bypassing red tape and financing issues. Using data from China's anti-corruption campaign in 2012, Mariassunta Gianetti shows that small, young - and potentially more productive - firms tend to perform better when corruption is cut. This video was recorded at CEPR's Third Annual Spring Symposium.

Superstar firms like Facebook and Tesla make a substantial difference to overall industry productivity. In his research, Dong Lou asks whether they also impact students’ choices of degree majors. Using data on students' college major choices and the stock returns and media coverage of relevant companies in the US, he shows that firm performance had a positive effect on encouraging students to choose relevant majors. But the relevant labour demand in those industries has not risen accordingly, which has depressed wages.

Research is increasingly pointing to the rising concentration of creative and science-oriented workers as the basic force for making cities, and large cities in particular, the contemporary motors of innovation. This column examines whether this is the case in Germany. The results suggest that creative workers’ innovation is constrained to the boundaries of the firm, while science-based workers generate considerable innovation spillovers. Policies to generate innovation in Germany are likely to yield greater returns by focusing on ‘geeks’ rather than ‘creatives’, and innovation policy should look beyond the largest cities to a broader range of territories that have proven attractive to ‘geeks’.

Patent protection is assumed to benefit entrepreneurs seeking investment, because patents signal quality and are an asset that can be resold if a startup fails. This column argues that the evidence for these benefits is inconclusive. Notably, patents acquired in a secondary market may be used for rent-seeking, rather than to incentivise innovation.

Evidence from the US indicates that business dynamism is declining, and that this affects overall productivity growth. This column explores business dynamism in Belgium between 1985 and 2014. The results show remarkable similarities to those from the US, suggesting that these changes are likely due to global trends such as the rise of information and communication technology.

The optimal set of industrial policies to tackle increased competition from global technological rivals is once again the centre of a heated debate, with protectionist policies now gaining traction. Drawing on US experience three decades ago, this column examines the effects of import tariffs and R&D subsidies on domestic firms’ global competitiveness, aggregate growth, and welfare. It argues that import tariffs generate large dynamic productivity losses and may enhance welfare only for a short time horizon and when trading partners do not retaliate. By contrast, R&D subsidies stimulate domestic innovation and increase welfare, especially over longer time horizons, without jeopardising the gains from trade.

Measuring innovative activity itself, rather than proxies such as R&D expenditures or patent volumes, is difficult. This column shows how patterns of economic activity can be used to measure increased innovative activity within firms. This ‘searching for black holes’ approach can be used to better understand the connection between innovation and productivity dispersion and growth.

Denmark is a paragon of economic development because it rapidly modernised its agriculture 150 years ago by using technology and cooperatives. This column argues that Denmark's development story has in fact been misrepresented. Rapid agricultural development was the end of a process begun by landed elites in the 18th century. It may be a mistake to cite the case of Denmark to argue that a country with a lot of peasants and cows can cooperate its way out of underdevelopment.

Baumol argued that structural change may lead to a productivity slowdown due to a reallocation of production to service industries with low productivity growth. This column uses a new framework to estimate the effects of Baumol’s disease on future productivity growth in the US. The results suggest that future structural change will not reduce productivity much further thanks to substitutability within the broader service sector.

Economists have been dismissive of cryptocurrencies, but fintech entrepreneurs and enthusiasts continue to see their disruptive potential. This column considers the theoretical and practical arguments on both sides of the debate. Traditional currencies are overwhelmingly superior as forms of money, and cryptocurrencies’ advantage in terms of lax regulation is unlikely to last. There remains, however, ample potential for innovation in payment systems.

Globalisation discontents blame trade for destroying jobs and slashing wages, while its supporters rebut that trade openness generates aggregate gains that can potentially benefit all. However, assessing the gains from trade represents a long-standing challenge for economists. This column argues that that accounting for firms' innovation responses doubles the gains from trade obtained in static quantitative models.

Europe currently faces multiple challenges on economic, demographic, and environmental fronts. All of these can be addressed by innovations in technology and process. This video discusses some of the outcomes of the EU-FRAME mid-term conference, outlining ways in which innovation policy can be designed so as to best serve welfare and productivity across all actors. This conference took place in March 2018 at ZEW, Mannheim.

CEPR is a partner of the FRAME Project, which is coordinated by ZEW. The CEPR team is led by Diego Comin, a Research Fellow in its Macroeconomics and Growth Programme. The FRAME project has received funding from the European Union's Horizon 2020 Research and Innovation Programme under the grant agreement No #727073.

Many economists argue that fixing inequality should not come at the expense of innovation. Philippe Aghion discusses the role innovation has to play in fostering growth and social mobility. This video was recorded at the RES annual conference in Spring 2015.

As the global economy continues to recover, trade frictions between advanced and emerging economies have started to appear. This column considers how Japan can continue its recent trend of economic expansion by addressing domestic growth opportunities while remaining resilient to international trade challenges. Both technological innovation and new business models are key to achieving this.
