The rate of productivity growth in advanced economies has been falling. Optimists hope for a fourth industrial revolution, while pessimists lament that most potential productivity growth has already occurred. This column argues that data on the research effort across all industries shows the costs of extracting ideas have increased sharply over time. This suggests that unless research inputs are continuously raised, economic growth will continue to slow in advanced nations.

The latest AI boom that started in 2012 shows no signs of fading, thanks to the recent availability of big data and widespread adoption of deep learning technologies. This column argues that this new combination of data and technology offers an unprecedented opportunity for society. AI will develop sustainably only if systems are in place to collect relevant data, and AI is not adopted for its own sake.

Artificial intelligence has been around since the 1950s, and has gone through many cycles of hype and ‘winters’. Based on a survey of senior executives from over 3,000 companies in ten countries, this column describes how artificial intelligence is experiencing a new spring and is here to stay. The authors also argue that it can bring firm-level productivity and profit growth, with employment dynamics that may not be as bad as anticipated by some.

Patent applications are a good indicator of the nature of technological progress. This column compares trends in applications for artificial intelligence patents in Japan and the US. One finding is that the Japanese market appears to be less attractive for artificial intelligence technology application, perhaps due to its stricter regulations on the collection and use of data.

Many economists throughout history have been proven wrong in predicting that technological progress will cause irreversible damage to the labour market. This column shows that so far, the labour market has always adapted to the replacement of jobs with capital, using evidence of new types of skilled jobs between 1970 and 2007. As long as the rate of automation of jobs by machines and the creation of new complex tasks for workers are balanced, there will be no major labour market decline. The nature of new technology, and its impact on future innovation potential, has important implications for labour stability.

The substitution of human labour by artificial intelligence and robots is a keenly debated topic. Some claim that a substantial share of jobs is at risk, while others argue that computers and robots will lead to product innovations and hence to unimaginable new occupations. This column uses a survey of Japanese firms to examine the impact of AI-related technologies on business and employment. Overall, firms expect a positive impact on business but a negative impact on employment. Firms with a highly skilled workforce, however, have a more optimistic view than firms with lower skilled employees.
