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.

Questions

  1. What is the difference between nominal and real GDP? Which of these helps to track changes in economic output?
  2. Looking at the chart above, summarise the key patterns in real GDP since the 1980s.
  3. What is a recession? What is a double-dip recession?
  4. What are some of the problems with the traditional definition of a recession?
  5. Explain the arguments for and against the proposition that the UK has recently experienced a double-dip recession.
  6. Can a recession occur if nominal GDP is actually rising? Explain your answer.

  8. Produce a short briefing paper exploring the prospects for economic growth in the UK over the next 12 to 18 months.

First the good news. Employment is rising and unemployment is falling. Both claimant count rates and Labour Force Survey rates are down. Compared with a year ago, employment is up 279,092 to 29,869,489; LFS unemployment is down from 7.87% to 7.69%; and the claimant count rate is down from 4.7% to 4.0%.

Now the bad news. Even though more people are in employment, real wages have fallen. In other words, nominal wages have risen less fast than prices. Since 2009, real wages have fallen by 7.6% and have continued to fall throughout this period. The first chart illustrates this. It shows average weekly wage rates in 2005 prices. (Click here for a PowerPoint of the chart.)

The fall in real wages is an average for the whole country. Many people, especially those on low incomes, have seen their real wages fall much faster than the average. For many there is a real ‘cost of living’ crisis.

But why have real wages fallen despite the rise in employment? The answer is that output per hour worked has declined. This is illustrated in the second chart, which compares UK output per worker with that of other G7 countries. UK productivity has fallen both absolutely and relative to other G7 countries, most of which have had higher rates of investment.

The falling productivity in the UK requires more people to be employed to produce the same level of output. Part of what seems to be happening is that many employers have been prepared to keep workers on in return for lower real wages, even if demand from their customers is falling. And many workers have been prepared to accept real wage cuts in return for keeping their jobs.

Another part of the explanation is that the jobs that have been created have been largely in low-skilled, low-wage sectors of the economy, such as retailing and other parts of the service sector.

But falling productivity is only part of the reason for falling real wages. The other part is rising prices. A number of factors have contributed to this. These include a depreciation of the exchange rate back in 2008, the effects of which took some time to filter through into higher prices in the shops; a large rise in various commodity prices; and a rise in VAT and various other administered prices.

So what is the answer to falling real wages? The articles below consider the problem and some of the possible policy alternatives.

Questions

  1. How are real wages measured?
  2. Why have real wage rates fallen in the UK since 2009?
  3. What factors should be included when measuring living standards?
  4. Why has employment risen and unemployment fallen over the past two years?
  5. What factors could lead to a rise in real wages in the future?
  6. What government policies could be adopted to raise real wages?
  7. Assess these policies in terms of their likely short-term success and long-term sustainability.

House prices in the UK are rising and the rise seems to be accelerating – at least until the latest month (August). They are now growing at an annualised rate of nearly 4%. This is the fastest rate for three years (see chart below: click here for a PowerPoint of the chart).

This may be worrying for Mark Carney, the Governor of the Bank of England, who is committed to avoiding a new house price bubble. The problem is that, under the recently issued forward guidance, the Bank of England is set to retain the current historically low Bank rate of 0.5% until unemployment has fallen to 7%. But that could be some time – probably around two years.

So what can the Bank do in the meantime and what will be the consequences?

The following article from The Guardian looks at the options.
