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.

Questions

  1. Why are numerous estimates of GDP made by the ONS?
  2. How is GDP measured? Is it an accurate measure of economic growth? What about economic development?
  3. Why does 0.3% growth in the first quarter of GDP not necessarily imply that the UK economy is recovering?
  4. Why have certain aspects of the UK economy performed better or worse than others?
  5. What areas should the government invest in, according to the IMF?
  6. Why would government spending in investment create economic growth? Is this likely to be short term or long term?

Have you ever woken in the night worrying about your finances? Most of us have. Our overall financial position undoubtedly exerts influence on our spending. Therefore, we would not expect our current spending levels to be entirely determined by our current income level.

Our financial health, or what economists call our net financial wealth, can be calculated as the difference between our financial assets (savings) and our financial liabilities (debt). Between them, British households have amassed a stock of debt of £1.423 trillion, almost as much as annual GDP, which is around £1.5 trillion (click here to download the PowerPoint.) We look here at recent trends in loans by financial institutions to British households. We consider the effect that the financial crisis and the appetite of individuals for lending is having on the debt numbers.

There are two types of lending to individuals. The first is secured debt and refers to loans against property. In other words, secured debt is just another name for mortgage debt. The second type of lending is referred to as unsecured debt. This covers all other forms of loans involving financial institutions, including overdrafts, outstanding credit card debt and personal loans. The latest figures from the Bank of England’s Money and Credit show that as of 31 March 2013, the stock of debt owed by individuals in the UK (excluding loans involving the Student Loans Company) was £1.423 trillion. Of this, £1.265 trillion was secured debt while the remaining £157.593 billion was unsecured debt. From this, we can the significance of secured debt. It comprises 89 per cent of the stock of outstanding debt to individuals. The remaining 11 per cent is unsecured debt.

The second chart shows the growth in the stock of debt owed by individuals (click here to download the PowerPoint chart). In January 1994 the stock of secured debt stood at £358.75 billion and the stock of unsecured debt at £53.774 billion. 87 per cent of debt then was secured debt and, hence, little different to today. The total stock of debt has grown by 246 per cent between January 1994 and March 2013. Unsecured debt has grown by 197 per cent while secured debt has grown by 253 per cent.

However, more recently we see a different picture evolving, more especially in unsecured debt. Since October 2008, the monthly series of the stock of unsecured debt has fallen on 47 occasions and risen on only 7 occasions. In contrast, the stock of secured debt has fallen on only 12 occasions and often by very small amounts. Consequently, the stock of unsecured debt has fallen by 23.2 per cent between October 2008 and March 2013. In contrast, the stock of secured debt has risen by 3.5 per cent. The total stock of debt has fallen by 0.4 per cent over this period.

Another way of looking at changes in the stock of debt is to focus on what are known as net lending figures. This is simply the difference between the gross amount lent in a period and the amount repaid. The net lending figures will, of course, mirror changes in the total debt stock closely. For example, a negative net lending figure means that repayments are greater than gross lending. This will translate into a fall in the stock of debt. However, some difference occurs when debts have to be written off and not repaid.

The third chart shows net lending figures since January 1994 (click here to download the PowerPoint chart). The chart captures the financial crisis very nicely. We can readily see a collapse of net lending by financial institutions to households. It is, of course, difficult to disentangle from the net lending figures those changes driven by changes in the supply of credit by financial institutions and those from changes in the demand for credit by individuals. But, we can be certain that the enormous change in credit levels in 2008 were driven by a massive reduction in the provision of credit.

To further put the net lending figures into context, consider the following numbers. Over the period from January 2000 to December 2007, the average amount of monthly net lending was £8.52 billion. In contrast, since January 2009 the average amount of net lending has been £691 million per month. Consider too the composition of this net lending. The average amount of net secured lending between January 2000 and December 2007 was £7.13 billion per month compared with £1.39 billion for net unsecured lending. Since January 2009, monthly net secured lending has averaged only £756 million while monthly net unsecured lending has averaged -£64.4 million. Therefore, repayments of unsecured lending have outstripped gross unsecured lending.

While further analysis is needed to fully understand the drivers of the net lending figures, it is, nonetheless, clear that the financial system of 2013 is very different to that prior to the financial crisis. This change is affecting the growth of the debt stock of households. This is most obviously the case with unsecured debt. The stock of unsecured debt in March 2013 is 24 per cent smaller than in its peak in September 2008. It is now the job of economists to understand the implications of how the new emerging patterns in household debt will affect our behaviour and overall economic activity.

The link below is to an article by Bill Gates, founder of Microsoft. He argues that per-capita GDP is a poor indicator of development, especially in Sub-Saharan Africa.

The problems with using GDP as an indicator of the level of development of a country are well known and several alternative measures are in common use. Perhaps the best known is the United Nations Development Programme’s Human Development Index (HDI), where countries are given an HDI of between 0 and 1. HDI is the average of three indices based on three sets of variables: (i) life expectancy at birth, (ii) education (a weighted average of (a) the mean years that a 25-year-old person or older has spent in school and (b) the number of years of schooling that a 5-year-old child is expected to have over their lifetime) and (iii) real gross national income (GNY) per capita, measured in US dollars at purchasing-power parity exchange rates (see Box 27.1 in Economics 8th edition for more details).

But although indicators such as this capture more elements of development than simple per-capita GNP or GNY, there are still serious shortcomings. A major problem is the lack of and inaccuracy of statistics, especially when applied to the rural subsistence and informal urban sectors. The problem is recognised and some countries are trying to address the problem (see the second article below), but the problem is huge. As Gates says:

It is clear to me that we need to devote greater resources to getting basic GDP numbers right. … National statistics offices across Africa need more support so that they can obtain and report timelier and more accurate data. Donor governments and international organisations such as the World Bank need to do more to help African authorities produce a clearer picture of their economies. And African policymakers need to be more consistent about demanding better statistics and using them to inform decisions.

Another problem is how you convert data into internationally comparable forms. For example, how are inflation, exchange rates, income distribution, the quality of health provision and education, etc. taken into account?

Questions

  1. By accessing the Human Development Index site, identify which countries have a much higher ranking by HDP than by per capita gross national income. Explain why.
  2. Why is expressing GNY in purchasing-power parity (PPP) terms likely to increase the GNY figures for the poorest countries?
  3. Explain the following quote from the Gates article: ‘I have long believed that GDP understates growth even in rich countries, where its measurement is quite sophisticated, because it is very difficult to compare the value of baskets of goods across different time periods’.
  4. Why is GNY per capita, even when expressed in PPP terms, likely to understate the level of development in subsistence economies?
  5. Explain whether the rate of growth of GNY per capita is likely to understate or overstate the rate of economic development of sub-Saharan African countries?
  6. Why are the challenges of calculating GDP or GNY particularly acute in sub-Saharan Africa?

High levels of government debt and the adverse effect this has on the economy has been a key influencing factor in the fiscal consolidation efforts across the world. A key factor providing evidence in support of the connection between high government debts and low economic growth was a paper by two Harvard economists. However, the data used in their research has been called into question.

As we saw in a previous post, It could be you, Carmen Reinhart and Kenneth Rogoff presented a paper back in January 2010. Their research suggested that when a country’s debt increases above 90% of GDP, economic growth will slow considerably. (Click here for a PowerPoint of the above chart.) As you might expect, given the timing of this research, policymakers were intrigued. For those governments in favour of cuts in government spending and increases in taxation to bring the government debt down, this research was dynamite. It seemed to provide the evidence needed to confirm that if left to grow, government debt will have a significantly adverse effect on growth. Here was evidence in favour of austerity.

But, did a simple error create misleading information? A student at the University of Massachusetts Amherst was trying to replicate the results found by Reinhart and Rogoff, but was unable to do so. Thomas Herndon contacted the Harvard professors and they sent him the spreadsheets they had used in their calculations. Looking through it, an error in calculating the average GDP was spotted. However, the student and his supervisors also engaged in further research and came across other inconsistencies. This led to a draft working paper being published in April. The paper did find the same correlation between high debt levels and low growth, but the outstanding results found by Reinhart and Rogoff disappeared. Responding to the error, the Harvard professors said:

We are grateful to Herndon et al. for the careful attention to our original Growth in a Time of Debt AER paper and for pointing out an important correction to Figure 2 of that paper. It is sobering that such an error slipped into one of our papers despite our best efforts to be consistently careful. We will redouble our efforts to avoid such errors in the future. We do not, however, believe this regrettable slip affects in any significant way the central message of the paper or that in our subsequent work.

So, how might this correction and the implications affect government policy? Are we likely to see a reversal in austerity measures? Only time will tell.
