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).

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.

There’s some good news and some bad news about the UK economy. The good news is that there are signs that the recovery is gathering momentum; the ‘green shoots’ are growing bigger. The bad news is that it’s the ‘wrong type of growth’!

One of the main underlying problems of the 2008 financial crisis was that household debt had been increasing to unsustainable levels, egged on by banks only too willing to lend, whether as personal loans, on credit cards or through mortgages. When the recession hit, many people sought to reduce their debts by cutting back on spending. This further fuelled the recession.

What the government and most economists hoped was that there would be some rebalancing of the economy, with less reliance on consumer spending to drive economic growth. Instead it was hoped that growth would be driven by a rise in investment and exports. Indeed, the 25% depreciation of sterling exchange between 2007 and 2009 was seen as a major advantage as this would boost the demand for exports and encourage firms to invest in the export sector.

But things haven’t turned out the way people hoped. The recession (or lack of growth) has been much deeper and more prolonged than previous downturns in the economy. Today, real GDP per head is more than 7% below the level in 2007 and many people have seen much bigger declines in their living standards.

But also, despite the austerity policies, the economy has not been ‘rebalanced’ towards exports and investment. Exports are 3% lower than in 2006 (although they did grow between 2009 Q2 and 2011 Q1, but have since stagnated). And investment is 27% lower than in 2006. Household consumption, however, has grown by about 2% and general government consumption by around 9% since 2006. The chart shows the figures, based on 2006 Q1 = 100.
(Click here for a PowerPoint of the chart.)

And recent evidence is that consumption is beginning to grow faster – not because of rising household incomes, but because of falling saving rates. In 2008, the household saving ratio had fallen to nearly 0% (i.e. households were on average saving about the same as they were borrowing). Then the saving ratio rose dramatically as people reined in their spending. Between 2009 and 2012, the ratio hovered around 7%. But in the first quarter of 2013, it had fallen to 4.2%

So the good news is that aggregate demand is rising, boosting economic growth. But the bad news is that, at least for the time being, this growth is being driven by a rise in household borrowing and a fall in household saving. The videos and articles consider whether this is, however, still good news on balance.

Questions

  1. What are forecasters expecting to happen to economic growth in the coming months? Why?
  2. What factors determine investment? Why has it fallen so substantially in the UK?
  3. Explain what is meant by the ‘accelerator’. Is the rise in consumption likely to lead to an accelerator effect and, if so, what will determine the size of this effect?
  4. Why have exports not grown more rapidly despite the depreciation of sterling after 2007?
  5. What will determine the rate of potential economic growth in the UK economy? How will a rise in real GDP driven by a rise in consumption impact on potential GDP and potential economic growth?
  6. What supply-side policies would you recommend, and why, in order to increase potential economic growth?

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.

In the blog The global economy we considered the economic performance of countries across the globe, including the UK. In the first estimate of UK economic growth for the first quarter of 2013, the economy grew at 0.3%, thus avoiding a triple-dip recession. This first estimate is always subject to change, but in this case, the data was confirmed.

The April 2013 figure provided by the ONS of 0.3% growth has been confirmed, once again indicating the slow recovery of the UK economy. Despite these more positive signs for the economy, the IMF has raised concerns of the weak performance of the UK and has urged the government to invest more in projects to stimulate growth. Although the economy has started to grow, economic growth has continued to remain weak since the onset of the financial crisis and recession. Martin Beck, an economist at Capital Economics said:

With employment and average earnings both dropping in the first quarter on their level in the previous quarter, the foundations for a sustained recovery, even one driven by consumers, still look pretty rickety.

Initial estimates by the ONS are always updated and there is still time for the 0.3% growth figure to be changed, as more data becomes available. (Click here for a PowerPoint of the chart.) This latest figure, although unchanged, has given a more concrete indication of where the UK economy is continuing to struggle. Consumer spending increased by only 0.1%, investment and exports declined, but in further signs of a weak economy, the building up of stocks by companies was a big contributor to the UK economic growth – a contribution of 0.4 percentage points. The service sector continued to growth with a 0.6 percentage point contribution to GDP.

So, what does the future look like for the UK? Although the estimate of 0.3% figure did prevent a triple-dip recession and the IMF did comment on the ‘improving health’ of the economy, signs of recovery remain weak.

Crucial to the recovery will be government spending, but more than this, the government spending must be in key growth industries. Data suggests that the UK invests less than other G8 countries as a percentage of GDP and this is perhaps one of the key factors that has prevented the UK recovery from gathering pace. The future of the UK economy remains uncertain and government policy will be crucial in determining this future course. The following articles consider the latest growth data.
