Growth and inequality are back at the centre of the economic debate. This column presents a framework for interpreting Thomas Piketty’s data based on Paul Romer’s model of endogenous growth. Two balanced growth regimes are possible in this framework: one (‘merit’) with a low capital–output ratio, a high interest rate, and high growth; and another (‘rent’) with a higher capital–output ratio, a somewhat lower interest rate, and much lower growth. An increase in the returns to physical capital accumulation compared to innovation could explain a shift from ‘merit’ to ‘rent’.

Offshoring of production can have a deep impact on the wages and welfare of workers with different abilities through its effect on technological progress. This column argues that, when labour is sufficiently cheap abroad, firms have incentives to offshore low-skill tasks and invest in skill-biased technologies at home. Over time, however, offshoring raises foreign wages. This increases demand for all firms and makes innovations complementing low-skill workers more profitable. As a result, offshoring can eventually lead to higher wages for everybody and less inequality.

Victory in World War I relied on three types of energy: renewable energy for food and fodder, fossil energy, and high explosive. This column argues that the Allies had a clear advantage in manpower, coal, and agriculture, but not enough for a quick decision. Mobilisation in continental economies curtailed food production, occasionally to a critical level. Technical competition was a matter of capacity for innovation, not of particular breakthroughs. Coercive military service and rationing of scarce energy and food had egalitarian consequences that continued after the war.

Africa has generated a lot of enthusiasm lately. The cynical view of the continent as a hopeless basket case has been replaced by the lofty narrative of Africa Rising. This column argues that Africa’s progress is impressive, and there is more to the story than a commodity boom. But Africa is at a crossroads. The opportunities are huge, but the road ahead is long, and will require persistent and patient effort from policymakers as well as business.

The Chinese government has been actively promoting innovation via policies such as R&D subsidies, tax relief, and location policies. Since 1995, central and local governments have established more than 100 clusters in over 60 cities. This column presents new evidence on the effect of the concentration of firms on product innovation (new products) in the manufacturing industries.

Innovation is a key driver of productivity growth, but innovation in the service sector has received relatively little attention. This column shows that the total factor productivity gap between Japanese firms with and without innovations is larger in services than in manufacturing. Whereas the percentage of firms holding patents is much higher in manufacturing than in services, trade secrets are just as important in both sectors. These results suggest that the protection of trade secrets makes an important contribution to productivity growth.

Many firms are replacing traditional working hours with more flexible arrangements, reflecting new thinking on employee motivation. This column presents evidence from Germany that trust-based working time is associated with increased innovation. However, trust-based working hours also contribute to the blurring of workers’ professional and private lives, and may lead to excessive overtime. Careful design of trust-based working arrangements is required to reap the innovations gains while avoiding the health pitfalls.

The Global Crisis brought a halt to three decades of R&D internationalisation, in which foreign firms’ share of total R&D expenditure had increased in almost all countries where data is available. However, this column argues that the crisis did not lead to a new global distribution of overseas R&D expenditure, despite the erosion of the EU’s share. The persistence of R&D expenditure is attributed to the costs of relocating R&D and to the autonomy of foreign subsidiaries.

Immigrants to the US are drawn from both ends of the education spectrum. This column looks at the effect of highly educated immigrants – in particular, those with degrees in Science, Technology, Engineering, or Mathematics – on total factor productivity growth. The authors find that foreign STEM workers can explain 30% to 60% of US TFP growth between 1990 and 2010.

Geoff Mulgan, Friday, April 11, 2014

Geoff Mulgan talks to Romesh Vaitilingam about his recent book, 'The Locust and the Bee: Predators and Creators in Capitalism's Future'. Mulgan suggests that the economic crisis was a dramatic reminder that capitalism can both produce and destroy, but that it also provides a historic opportunity to choose a radically different future for capitalism - one that maximizes its creative power yet minimizes its destructive force. They discuss the importance of social innovation and the creative economy. The interview was recorded in May 2013.

Internationalisation and innovation policies are frequently considered to be key drivers of growth. This column documents a strong positive association between internationalisation, innovation, and productivity at the firm-level across seven European countries. This association continues to hold after controlling for country, size, industrial sector, and firm specific characteristics, with some evidence of causality running from innovation to internationalisation. The analysis suggests that policymakers should coordinate, if not integrate, innovation and internationalisation policies in order to boost productivity and growth.

Outsourcing is a controversial practice. This column looks at its effects on firm-level innovation in emerging markets. The authors find robust evidence that outsourcing is positively related to various innovation measures. However, outsourcing only leads to increased R&D spending in countries where intellectual-property rights are well-protected.

In recent years, policymakers have enthusiastically backed the fashionable ‘creative industries’. This column presents new research on the creative sector, creative occupations and innovation in the UK. The results raise questions about the dominant perception of the creative industries as an ‘innovative’ sector. Instead, it might be more appropriate for policymakers to focus on creative workers regardless of the sector in which they work.

Migration is a hot-button issue across the globe. This column summarises new evidence on the patterns of skilled-worker migration, focusing on the specific case of inventors. A novel data source that traces worldwide migration flows for inventors suggests that, excluding a few nuances, the economic incentives for general migration also seem to influence inventors’ migration decisions.

Contrary to received wisdom, entrepreneurial clusters in the US – like Silicon Valley – are seen as success stories. But what is the rationale behind these clusters? Do they actually work? This column reviews the evidence and discusses localised policies currently being pursued in the US. In general, our understanding of what works remains limited and economists should more thoroughly pursue researching the effects of entrepreneurial clusters.

Do patents encourage innovation? This column presents a new analysis, suggesting that patent rights block cumulative innovation only in very specific environments. To encourage innovation, remedial government policies should be targeted; a ‘broad based’ scaling back of patent rights is unlikely to be appropriate. Policies and institutions should facilitate more efficient licensing, promoting cumulative innovation without diluting the innovation incentives that patents provide.

Josh Lerner, Thursday, March 21, 2013

Josh Lerner of Harvard Business School talks to Romesh Vaitilingam about his book "The Architecture of Innovation: The Economics of Creative Organizations". They discuss a variety of issues around the challenges of innovation, including corporate venturing, venture capital-based enterprises, patents and public investment in science. The interview was recorded in Washington, DC, at the annual meeting of the Toulouse Network on Information Technology in September 2012.

Many of the emerging economies of the last two decades are now ensnared by ‘the middle-income trap’, in which middle-income countries don’t quite push through to high income status. This column presents recent research suggesting that, if governments act early and decisively to improve access to advanced infrastructure, enhance the protection of property rights, and reform labour markets, trapped economies – like their East Asian counterparts in the 1990s – can push on through.

Do the ‘cuddly’ Nordic countries free ride on the ‘cut-throat’ incentives for innovation in US-style economies? Don’t PCs, the internet, Google, Windows, iPhones and the Big Mac speak for themselves? This column argues that, despite a higher overall tax burden and more generous safety nets, the Nordics have generated at least as much – if not more – innovation than the US. So far, ‘cut-throat’ capitalism has not been the only road to an innovative economy.
