Constructing growth without construction: The UK growth paradox

In the blog the service sector continues to drive the UK business cycle written in October 2014 we observed how UK growth was being driven by the service sector while other industrial sectors struggled. The contrasting performance across UK industry appears now to be even more marked. The latest GDP numbers from the Office for National Statistics contained in Gross Domestic Product: Preliminary Estimate, Quarter 4 (Oct to Dec) 2015 show the economy’s output expanded by 0.5 per cent in the fourth quarter. Yet the construction sector is in recession following contractions of 1.9 per cent (Q3) and 0.1 per cent (Q4). Here we update our earlier blog to evidence the UK’s growth paradox.

Preliminary estimates suggest that the UK economy expanded by 0.5 per cent in the final quarter of 2015 following on from growth of of 0.4 per cent in the third quarter. 2015 as a whole saw output grow by 2.2 per cent, down from 2.9 per cent in 2014 and a little below the average over the past 60 years of around 2.6 per cent.

Chart 1 shows quarterly economic growth since 1980s (Click here for a PowerPoint of the chart). It illustrates nicely the inherent volatility of economies – one of the threshold concepts in economics.The average quarterly rate of growth since 1980 has been 0.5 per cent so on the face of it, a quarterly growth number of 0.5 per cent might seem to paint a picture of sustainable growth. Yet, the industrial make up of growth is far from balanced.

Consider now Chart 2 (Click here for a PowerPoint of the chart). It allows us to analyse more recent events by tracking how industrial output has evolved since 2006. It suggests an unbalanced recovery following the financial crisis. In 2015 Q4 the economy’s total output was 6.6 per cent higher than in 2008 Q1 with service-sector output 11.6 per cent higher. However, a very different picture emerges for the other principal industrial types.

The economy’s total output surpassed its 2008 Q1 peak in 2013 Q2, but output across the production industries in 2015 Q4 remains 9.4 per cent lower than in 2008 Q1 (and 6.4 per cent lower specifically within manufacturing) and 4.2 per cent lower in the construction sector. However, output in the agricultural sector has rebounded and is now 8.4 per cent higher than in 2008 Q1.

The growth data continue to show the British economy struggling to rebalance its industrial composition. With output in construction in 2015 Q4 2 per cent lower than it was in Q2 and manufacturing output 0.4 per cent lower, UK growth remains stubbornly dependent on the service sector.
