The service sector continues to drive the UK business cycle

The latest GDP numbers from the Office for National Statistics contained in Quarterly National Accounts, Q2 2014 show the economy’s output expanded by 0.9 per cent in the second quarter. This follows on the back of a 0.7 per cent increase in output in Q1 2014. The economy’s output is now thought to be 0.7 per cent above its Q1 2008 peak. Yet, the data show very different profiles for the four principal industrial sectors. The service sector appears to be ploughing ahead while the rest (production, construction and agriculture) lag behind.

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. On the face of it, a quarterly growth number of 0.9 per cent would appear very robust. Of course, this has to been set in the context of the 2008/9 recession. UK output peaked in Q1 2008 (£414.424 billion at 2011 prices). The revised data now show that there followed 5 quarters of declining output (previously, data suggested the duration of the recession was 6 quarters). During this period output shrank 6 per cent (GDP at 2011 prices had fallen by Q2 2009 to £389.388 billion ).

Chart 1 highlights two earlier downturns. First, there is the recession of the early 1980s. We can see the 5-quarter recession that commenced in Q1 1980. By the end of this recession output had shrunk by 4.5 per cent. Second, there is the recession of the early 1990s which commenced in Q3 1990. Again, this recession lasted five quarters. By the time the economy had come out of recession it had shrunk 2.2 per cent.

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. From it, we observe that in Q2 2014 service-sector output was 6.5 per cent higher than in Q1 2008. However, a very different picture emerges for the other principal industrial types. Output across the production industries remains 9.7 per cent lower, 9.2 per cent lower in agriculture and 8.9 per cent lower in the construction sector.

In short, the British economy continues to struggle to rebalance its industrial base. The business cycle remains heavily dependent on the service sector.
