The adoption of information technology can cause polarisation in the labour market via the displacement of routine cognitive jobs. This column uses data on over 200,000 firms in the US from 1990 to 2015 to show that the labour savings from IT are largest in big cities and metropolitan areas, where wages are higher, so urban firms have the biggest incentives to invest in these technologies. This in turn leads to the polarisation of occupations across geography and accounts for the rise in wage inequality within cities.

Industrial policies can be an effective tool for governments to shape the development of different sectors to achieve productivity growth. But there is little evidence of their effectiveness or efficiency. This column examines the impact of an income tax break for IT workers in Romania. The findings suggest that targeted policies of this kind can boost key sectors. This finding is encouraging in terms of the ability of governments to design and implement effective industrial policies.

Productivity growth in southern Europe has been lower than in other developed countries. The column argues that this has in large part been caused by slow adoption of information technology, compounded by inefficient management. Without improvements in management practices, increased IT spending will not close the productivity gap.

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.

In spite of its potential, the use of digital technology is still basic in most developing countries. This column presents evidence that firms in Mexico facing higher external competition have used IT more intensively and efficiently. External competition has encouraged them to make the necessary complementary investments in innovation and organisational changes.

Services trade has increased dramatically in the last 20 years. This column examines data from Belgium and suggests that the change in IT use does not translate into higher services exports. It argues instead that offshoring is a key factor contributing to the rise of services trade.

It has taken a long time to confirm that computers boost productivity. The key seems to lie in management and internal organisation. That’s why IT has helped US firms so much more than their European counterparts.

There has already been evidence suggesting that information technology (IT) makes significant contributions to productivity; the authors of CEPR DP 6260 explore its impact on individual users in a white-collar setting.
