Back in 1987, the Nobel prize-winning economist Robert Solow observed that ‘you can see the computer age everywhere but in the productivity statistics!’ (quoted in Rotman, 2018). This dichotomy between limited productivity growth and rapid technological progress is now commonly described as the ‘Solow or productivity paradox’.At present, the term ‘productivity paradox’ increasingly refers to instances where productivity is either feeble or growing slowly. In the United Kingdom, there has been a slowdown in productivity growth since the Global Financial Crisis (GFC). The economic implications of this slowdown have been far-reaching for London and other regions (figure B1).London’s productivity picture How has London been performing? Data from the Office for National Statistics (ONS) reveals that the capital continues to outperform other UK regions: in 2019, London’s output per hour across all industries was 23 per cent higher than that of the Southeast and about 32 per cent higher than the United Kingdom (figure B2).
