One very important characteristic of economic growth is its short-term volatility. The volatility of growth underpins the idea of business cycles and on occasions results in recessions. The traditional definition is where real GDP (output) declines for 2 or more consecutive quarters. Interestingly, the latest GDP numbers contained in the Quarterly National Accounts mean that the recession previously evidenced from 2011 Q4 to 2012 Q2 has effectively disappeared. Nonetheless, output today is still 3.3 per cent lower than before the 2008 economic downturn.
The ONS’s latest output numbers raise some interesting questions around our understanding of what constitutes a recession. Should, for instance, we define it solely in terms of real GDP and, even if we do, is a strict statistical definition based around two consecutive quarterly falls appropriate? The recent estimates from the ONS show that the 2008/9 recession saw output fall by 7.2 per cent. They show that UK output peaked in 2008Q1 (£392.786 billion at 2010 prices). There then followed 6 quarters during which output declined.
Output declined again in 2010 Q4 (-0.2% growth) and again in 2011 Q4 (-0.1% growth). The new estimates of real GDP for 2011 Q4 and 2012 Q1 are now identical at £376,462 billion (at 2010 prices). Previous revisions have also seen the 2012 Q1 growth number revised up and, hence, a further recession resulting in a double-dip recession has effectively now been statistically removed. The 2013 Q1 Quarterly National Accounts revised growth up so that 2012 Q1 only saw a percentage fall when measured to the third decimal place (–0.007% growth).
While output is now portrayed as (very) flat in 2012 Q1, it did fall again in 2012 Q2 (-0.5 per cent growth) and in 2012 Q4 (-0.3 per cent growth). Moving forward in time, the latest ONS numbers show that the economy grew by 0.4 per cent in 2013 Q1 (to £377,301 billion at 2010 prices) and by 0.7 per cent in 2013 Q2 (to £379,780 billion at 2010 prices). Despite this, output remains 3.3 per cent below its 2008 Q1 peak. A more positive spin on the numbers would be to point out that output is up 4.2 per cent from its 2009 Q3 trough (£364,557 billion at 2010 prices).
Perhaps the debate around the appearance and disappearance of recessions in official data strengthen the argument for a more holistic and considered view of what constitutes a recession. In the USA the wonderfully-named Business Cycle Dating Committee takes a less fixed view of economic activity and, hence, of recessions. Its website argues:
It (the Committee) examines and compares the behavior of various measures of broad activity: real GDP measured on the product and income sides, economy-wide employment, and real income. The Committee also may consider indicators that do not cover the entire economy, such as real sales and the Federal Reserve’s index of industrial production (IP).
Of course, the advantage of focusing on real GDP alone in measuring activity and in determining recessions is that it is usually very straightforward to interpret. Regardless of whether the UK did or did not experience a recession at the end of 2011 and into 2012, the chart helps to put the recent growth numbers into an historical context. It shows the quarterly change in real GDP since the 1980s.
From the chart, we can see the 5-quarter recession that commenced in 1980 Q1 when output shrunk by 4.6 per cent, the 5-quarter recession that commenced in 1990 Q3 when output shrank by 2.4 per cent and the 6-quarter recession that commenced in 2008 Q2 when output shrank by 7.2 per cent. (Click here to download a PowerPoint version of the chart.)
The chart allows to see the other characteristic of growth too: over the long run growth is positive. Since 1980, the average rate of growth per quarter has been 0.57 per cent. This is equivalent to an average rate of growth of 2.3 per cent per year.
Since 2008 Q2, quarterly growth has averaged -0.16 per cent which is equivalent to an annual rate of growth of -0.63 per cent! In any language these are extraordinary numbers and certainly help to put the recent rebound in growth into context.

Investment is essential for the growth of any economy, but none more so for an economy recovering from a severe downturn, such as the UK. Not only will it bring in much needed money and then create jobs for UK residents, but it will also continue to build ties between the UK and the world’s fastest growing economy.
George Osborne has been in China promoting business opportunities for investment in the UK and one such investment is into Manchester Airport. The ‘Airport City’ Project will be a combined effort, or a Joint Venture, between the Greater Manchester Pension Fund, the UK’s Carillion Plc and Beijing Construction Engineering Group. The plan is to create offices, hotels, warehouses and manufacturing firms, bringing in thousands of jobs in the process, thus providing a much needed boost to the British economy. Britain is already one of the top nations attracting Chinese investment, with more than double the amount of any other European nation. George Osborne is clearly in favour of further improving business ties with China, saying:
I think it shows that our economic plan of doing more business with China and also making sure more economic activity in Britain happens outside the City of London is working…That’s good for Britain and good for British people.
However, the benefit of such investment from China into the UK, is not just of benefit to our domestic economy. China will also reap benefits from its involvement in projects, such as the development of Manchester’s airport. The Managing Director of BCEG, Mr Xing Yan, said:
To be included in such an interesting and unique development is a real honour…We see our involvement in Airport City as an extension of the memorandum of understanding between China and the UK, where we have been looking to further explore joint infrastructure opportunities for some time.
The airport investment by China is only one of many of its recent forays into the UK economy. Other investments include plans to rebuild London’s Crystal Palace and plans to create a third financial district near London’s City Airport.
Some may see more Chinese involvement in UK business as a threat, but for most it is viewed as an opportunity. An opportunity that both Boris Johnson and George Osborne will undoubtedly exploit as far as possible, with the hope that it will generate income, employment and growth. The following articles consider this investment opportunity.

The 2020 Olympics has just been awarded to Tokyo, beating Madrid and Istanbul. Concerns over the safety of the games in Tokyo, with the city being perceived as relatively close to the Fukushima nuclear plant, were overcome with the help of an address by the Japanese Prime Minister, Shinzo Abe. So, what are the economic implications of this latest development in the sporting world?
When London was awarded the 2012 Olympic Games, estimates suggested that it would generate a £16.5 billion contribution to GDP. With many new construction projects, there was the inevitable injection of government expenditure. This led to the creation of new jobs and thus successive employment multiplier effects were generated. This is also likely to be true for Tokyo, with current proposals suggesting that ten new permanent sites will be built to host the various sports of the Games. This will undoubtedly generate new jobs and will provide an almost certain boost to the construction industry. This, in turn, will generate further multiplier effects across a multitude of industries and across the rest of the country.
There will also be further economic effects, for example on Japanese investment and stocks and shares, with a boost in confidence and optimism. A Tokyo-based fund manager, Hiroshi Fujumonto, said:
Olympics-related stocks are yet to fully price in the decision, even though they’ve already outperformed … In the short term the entire Japanese share market will get a boost from celebratory buying and expectations for the event’s economic impact.
This was also confirmed by Shinzo Abe, when he commented after the victory was announced that ‘I want to make the Olympics a trigger for sweeping away 15 years of deflation economic shrinkage.’ 
The Japanese economy has been struggling for many years and this may be the much needed boost to the country’s optimism, infrastructure and economy.
As the world’s third largest economy, this economic boost is also likely to have knock-on effects on other countries across the world, though it is more likely to be the long-term impact that is important here. Just as it was with the London Olympics, the final effect and cost will only be known some years after the Olympics are held, but for now the work will start for Japan.

In our blog How sustainable is UK consumer spending? we considered concerns of some commentators that consumer spending was growing unduly quickly given the absence of any sustained growth in disposable income. The Second Estimate of GDP, Q2 2013 reports that the economy grew by 0.7 per cent in the second quarter of the year, with household expenditure growing by 0.4 per cent.
Because household spending makes up about two-thirds of aggregate demand in the UK it is important to keep an eye on it. The latest figures show that the real value of consumer spending by British households has risen in each quarter since 2011 Q4. In other words, the volume of household purchases has risen for seven consecutive quarters. Over the period, the growth in real consumer spending has averaged 0.4 per cent per quarter.
The chart helps to demonstrate the stark turnaround in the growth in consumer spending. Over the period from 2008 Q1 to 2011 Q3, real consumer spending typically fell by 0.4 per cent each quarter. As we noted in our previous blog, this was a period when the global financial system was in distress, with the availability of credit severely dampened, but also a period when households were concerned about their own financial balances and the future prospects for growth. Over the same period, real GDP typically fell by a little under 0.3 per cent each quarter. (Click here to download a PowerPoint of the chart.)
The real value of consumer spending has yet to return to its 2007 Q4 peak (£242 billion at 2010 prices). In 2013 Q2 the real value of consumer spending is estimated still to be 3 per cent below this level (£235 billion at 2010 prices). These figures are mirrored by the economy at large. Real GDP peaked in 2008 Q1 (£393 billion at 2010 prices). Despite the back-to-back quarterly increases in real GDP of 0.3 per cent in Q1 and 0.7 per cent in Q2, output in 2013 Q2 (£380 billion at 2010 prices) remains 3.2 per cent below the 2008 Q1 peak.
While real consumption values are below their 2007 Q4 peak, the concern is whether current rates of growth in consumer spending are sustainable. In particular, should this growth cause the household sector financial distress there would be real pain for the economy further down the line. Some commentators argue that the latest GDP figures are consistent with a more balanced recovery. In Q2 economic growth was supported too by other parts of the economy. For instance, we saw a 3.6 per cent rise in export volumes and a 1.7 per cent rise in gross fixed capital formation (i.e. investment expenditure).
Nonetheless, it is the protracted period over which consumer spending has been growing robustly that concerns some economists. Hence, we will need to continue to monitor the growth in all components of aggregate demand and, in particular, changes in household consumption, income, saving and borrowing.

- What are the expenditure components that make up Aggregate Demand?
- Explain what you understand by consumption smoothing.
- Why would we would typically expect consumption growth to be less variable than that in disposable income?
- Would we expect consumption growth to always be less variable than that in disposable income? Explain your answer.

Household spending makes up about two-thirds of aggregate demand in the UK. Understanding its determinants is therefore important to understanding short-term economic growth. The real value of consumer spending by British households has risen in each quarter since 2011 Q4. Over the same period real disposable income has flat-lined. This suggests that the British household sector has stepped up attempts to smooth their longer-term spending profile despite the current absence of growth in their real incomes.
When viewed over many years, disposable income and consumer spending grow at very similar rates. After stripping out inflation we find that over the past 50 years both have grown at about 2½ per cent per annum. However, if we measure growth from one quarter of the year to the next we tend to find that consumption growth is less variable than disposable income. This is known as consumption smoothing.
Chart 1 shows the quarterly percentage change in consumption and disposable income since 1998. (Click here to download a PowerPoint of the chart).The variability in the disposable income series is generally greater than that in consumption so helping to illustrate consumption smoothing.
Consumption smoothing is facilitated by the financial system enabling us to either borrow to supplement our spending or to save to enjoy more spending in the future. The financial system can help households to avoid large variations in their spending over short periods.
Consumption smoothing does not prohibit falls in consumption nor periods when it is more variable than income. Over the period from 2008 Q1 to 2011 Q3, real consumption typically fell by 0.4 per cent each quarter while disposable income was flat. This was a period when the global financial system was in distress. Sharp contractions in credit meant that the financial system was no longer able to support economic activity as it had previously. Furthermore, households too looked to repair their balance sheets with economic uncertainty acting as an incentive to do so.
What is interesting is the extent to which British households are spending again. Since 2011 Q4 the real value of spending has typically expanded by 0.4 per cent each quarter while income growth remains largely absent. One might argue that this just demonstrates a willingness for households to engage in consumption smoothing. With credit conditions still tight, the growth in spending has been aided by a decline in the saving ratio. 
This can be seen from Chart 2.
In 2009 Q2 the proportion of income saved hit 8.6 per cent having been as low as 0.2 per cent in 2008 Q1. In 2013 Q1 the saving ratio had fallen back to 4.2 per cent. (Click here to download a PowerPoint of the chart.)
It is of course all too easy to over-interpret data. Nonetheless, there be will concern if households look to maintain consumption growth at rates substantially greater than those in disposable income for too long a period of time. Consumption smoothing could become a real problem for future economic activity if it was to result in a financially distressed household sector. Hence, an important question is the extent to which current rates of consumption growth are sustainable. Future consumption and income trends will therefore be analysed with enormous interest.
