Explaining productivity figures needs interpretation and judgement.
For example, the UK has had low productivity growth for the last few years.
Bank of England economists suggest that one reason might be that fewer businesses have collapsed in recent years, meaning fewer workers have moved from low productivity into higher productivity firms.
As the economy improves, some of these firms that have survived and staggered through the last few years may be able to pick up production without hiring additional labour. so, we may see productivity rises in the new couple of years.
