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.

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.

One very important characteristic of economic growth is its short-term volatility. Economic activity is notoriously volatile. It is such a fundamental idea that economists refer to it as one of their threshold concepts. The volatility of growth sees occasional recessions. The traditional definition is where real GDP (output) declines for 2 or more consecutive quarters. The latest figures from the Quarterly National Accounts call into question whether the UK technically experienced a recession at the start of 2012 with output broadly flat in 2012 Q1 following a contraction of 0.1 per cent in 2011 Q4.
The ONS’s latest output numbers raise some interesting questions around our understanding of what constitutes a recession. These figures show that the 2008/9 recession was deeper than first thought with output declining by 7.2 per cent. They show that UK output peaked in 2008Q1 (£392.786 billion at 2010 prices). There then followed 6 quarters where output declined.
Output declined again in 2010 Q4 (–0.2% growth) and again in 2011 Q4 (–0.1% growth). But then interpretations of the data become more controversial. Not least, we get in the debates concerning the accuracy with which we can expect to measure the size of the economy and so to how many decimal places one should realistically measure a rise or fall. In terms of the raw real GDP numbers output fell in 2012 Q1. In 2011 Q4 GDP is estimated at £376,462 billion (at 2010 prices) ‘falling’ to £376,436 billion (at 2010 prices) in 2012 Q1. But, this is a percentage fall only when measured to the third decimal place (–0.007% growth).
In its publication Impact of changes in the National Accounts and economic commentary for Q1 2013 the ONS argue that:
While some commentators may attempt to read some significance into this revision, particularly in the context of whether the UK experienced a “double-dip” recession, it is clearly absurd to imagine that it is possible to measure the size of the economy to this degree of accuracy. The best interpretation of the Blue Book figures is that the economy was flat in the first quarter of 2012, and 0.6% larger than in the same quarter of 2011.
It is however understandable that those with vested interests – including economists, policy-makers and politicians – will take a slightly different view and will read more into the figures than perhaps an objective, sober view might demand. What appears more certain is that output did again fall in 2012 Q2 (–0.5 per cent growth) and in 2012 Q4 (–0.2 per cent growth). Despite estimated growth of 0.3 per cent in 2013 Q1, output remains 3.9 per cent lower than at its 2008 Q1 peak.
Perhaps the ‘absurdity’ or not around the debate of a double-dip recessions strengthens 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 has experienced or not two recessions in close proximity, our chart helps to put the recent growth numbers into an historical context
. It shows both the quarter-to-quarter changes in real GDP (left-hand axis) and the level of output as measured by GDP at constant 2010 prices (right-hand axis). Click here to download the chart to PowerPoint.
The chart captures nicely the twin characteristics of growth. Since 1960, the average rate of growth per quarter has been 0.63 per cent. This is equivalent to an average rate of growth of 2.55 per cent per year. Since 2008 Q2, quarterly growth has averaged –0.19 per cent which is equivalent to an annual rate of growth of –0.78 per cent! In any language these are extraordinary numbers. Indeed, one could argue that focusing any policy debate around whether or not the UK experienced a double-dip recession rather misses the more general point concerning the absense of any sustained economic growth since 2008.

In the blogs The capital adequacy of UK banks and A co-operative or a plc? we focus on how British banks continue to look to repair their balance sheets. To do so, banks need to ‘re-balance’ their balance sheets. This may involve them holding more reserves and equity capital and/or a less risky and more liquid profile of assets. The objective is to make banks more resilient to shocks and less susceptible to financial distress.
This will take time and even then the behaviour of banks ought to look like quite different from that before the financial crisis. All of this means that we will need to learn to live with new banking norms which could have fundamental consequences for economic behaviour and activity.
The increasing importance of financial institutions to economic activity is known as financialisation. It is not perhaps the nicest word, but, in one way or another, we all experience it. I am writing this blog in a coffee shop in Leicester having paid for my coffee and croissant by a debit card. I take it for granted that I can use electronic money in this way. Later I am going shopping and I will perhaps use my credit card. I take this short term credit for granted too. On walking down from Leicester railway station to the coffee shop I walked past several estate agents advertising properties for sale. The potential buyers are likely to need a mortgage. In town, there are several construction sites as Leicester’s regeneration continues. These projects need financing and such projects often depend on loans secured from financial institutions.
We should not perhaps expect economic relationships to look as they did before the financial crisis. The chart shows how levels of net lending by financial institutions to households have dramatically fallen since the financial crisis. (Click here for PowerPoint of chart.)
Net lending measures the amount of lending by financial institutions after deducting repayments. These dramatically smaller flows of credit do matter for the economy and they do affect important macroeconomic relationships.
Consider the consumption function. The consumption function is a model of the determinants of consumer spending. It is conventional wisdom that if we measure the growth of consumer spending over any reasonably long period of time it will basically reflect the growth in disposable income. This is less true in the short run and this is largely because of the financial system. We use the financial system to borrow and to save. It allow us to smooth our consumption profile making spending rather less variable. We can save during periods when income growth is strong and borrow when income growth is weak or income levels are actually falling. All of this means that in the short term consumption is less sensitive to changes in disposable income that it would otherwise be.
The financial crisis means new norms for the banking system and, hence, for the economy. One manifestation of this is that credit is much harder to come by. In terms of our consumption function this might mean consumption being more sensitive to income changes that it would otherwise be. In other words, consumption is potentially more volatile as a result of the financial crisis. But, the point is more general. All spending activity, whether by households or firms, is likely to be more sensitive to economic and financial conditions than before. For example, firms’ capital spending will be more sensitive to their current financial health and crucially to their flows of profits.
We can expect particular markets and sectors to be especially affected by new financial norms. An obvious example is the housing market which is very closely tied to the mortgage market. But, any market or sector that traditionally is dependent on financial institutions for finance will be affected. This may include, for example, small and medium-sized enterprises or perhaps organsiations that invest heavily in R&D. It is my view that economists are still struggling to understand what the financial crisis means for the economy, for particular sectors of the economy and for the determination of key economic relationships, such as consumer spending and capital spending. What is for sure, is that these are incredibly exciting times to study economics and to be an economist.

When you are next in town shopping, just keep in mind that consumer spending accounts for a little over 60 per cent of GDP. Therefore, consumption is incredibly important to the economy. How consumers behave is crucial to our short-term economic growth. The second estimate of British growth from the Office for National Statistics shows that the economy expanded by 0.3 per cent in the first three months of 2013. This follows a 0.3 per cent decline in the final quarter of 2012. Real household expenditure rose by just 0.1 per cent in Q1 2013. However, this was the sixth consecutive quarter in which the volume of purchases by households has grown.
The growth in the economy is measured by changes in real GDP. Chart 1 shows the quarter-to-quarter change in real GDP since Q1 2008. (Click here to download a PowerPoint of the chart). During this period the economy is thought to have contracted in 10 of the 21 quarters shown. Furthermore, they show a double-dip recession and so two periods in close proximity where output shrank for two or more quarters. While more recent output numbers are frequently revised, which could see the double-dip recession possibly ‘statistically wiped’ from history, the period since 2008 will always been one characterised by anemic growth. The average quarterly growth rate since Q1 2008 has been -0.12 per cent.
Chart 2 shows from Q1 2008 the quarterly growth in household expenditure in real terms, i.e. after stripping the effect of consumer price inflation. (Click here for a PowerPoint of the chart). Over the period, the volume of household consumption has typically fallen by 0.18 per cent per quarter. Hence, consumption has feared a little worse than the economy has a whole.
While the annualised rate of growth for the economy since Q1 2008 has averaged -0.47 per cent that for consumer spending has averaged -0.73 per cent. However, these figures disguise a recent improvement in consumer spending growth. This is because the volume of consumption has in fact grown in each of the six quarters since Q4 2011. In contrast, the economy has grown in only 2 of these quarters. It is, of course, much too early to start trumpeting consumption growth has heralding better times, not least because the 0.1 per cent growth in Q1 2013 is the weakest number since positive consumption growth resumed at the back end of 2011. Nonetheless, the figures do deserve some analysis by economists to understand what is going on.
A slightly less promising note is struck by the gross fixed capital formation (GFCF) numbers. These numbers relate to the volume of investment in non-financial fixed assets, such as machinery, buildings, office space and fixtures and fittings. Chart 3 shows the quarterly growth in the volume of GFCF since Q1 2008. (Click here for a PowerPoint of the chart). The average quarterly rate of growth over this period has been -0.77 per cent. This is equivalent to an annual rate of decline of 3.9 per cent. GFCF has risen in only 7 of these quarters, declining in the remaining 14 quarters.
Worryingly, gross fixed capital formation has decreased in each of the last three quarters. While these figures may reflect continuing difficulties encountered by businesses in obtaining finance, they may also point to lingering concerns within the business community about the prospects for sustained growth. Therefore, it is important for economists to try and understand the drivers of these disappointing investment numbers and, hence, whether it is these or the slightly better consumption numbers that best hint at our short-term economic prospects.

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.
