As time goes to infinity, the probability that a productivity analyst will wonder ‘which sectors are driving these trends?’ goes to one. You present an interactive sectoral productivity tool to help you explore this question without any fuss.
Labour productivity is defined as real value-added (£ worth of output created) per labour unit (number of employees) for the set of relevant sectors (up to whole economy).
It’s as simple as choosing the sectors and clicking 'plot': our tool will show the path of productivity for an economy of just the selected sectors. You can plot as many lines as you like, and also define the time period you’re interested in by drawing and resizing a grey box in the graph below the main chart, which will update like magic. To see which sectors are included in a line, hover over its colour in the key below the chart; to clear it, click that colour box.
You might wonder, for example, whether the productivity puzzle remains after excluding the financial sector. To investigate this, select all sectors except ‘Finance and insurance’ in the menu below the chart and click ‘Plot’; and you will see that the puzzle does, in fact, remain.
The possibilities are almost endless (with 20 options and at least one selection, there are 1,048,575 combinations to choose from), so we’ll leave it to you from here.
This chart was created for the Bank of England's Bank Underground blog .
The aggregation affected by the tool isn’t strictly accurate because we’re adding up CVM series, which are non-additive. A full analysis would account for the fact that volume measures of UK GDP are annually chain-linked up to the current reference year (2013), which we recommend you do for deeper analysis.
The data are quarterly, SIC07 section level aggregate real value-added and productivity jobs (with government sectors apportioned by LFS weights), available from the Office of National Statistics at the links.
