Category: Essential Economics for Business: Ch 10

Economic growth in developed countries, like the UK, exhibits two important characteristics. First, growth is positive over the long run such that the volume of output increases over time. Second, growth in the short-term is highly variable with patterns in the volume of output creating business cycles. With increased global interdependence through trade and integrated financial systems, domestic business cycles often resemble a global or international business cycle. This was certainly the case during the late 2000s. Recent releases from the Office for National Statistics provide an opportunity to look again at the characteristics of UK economic growth. In particular, they show the importance of differentiating between nominal and real values. Furthermore, revisions to the data have somewhat revised our view of economic growth before and after the economic crisis of the late 2000s.

The value of goods and services produced in the UK in 2010, as measured by GDP, is estimated at £1.46 trillion. This is the nominal GDP estimate because it measures the economy’s output for 2010 using the prices of 2010. Back in 1948, GDP measured at 1948 prices was £11.97 billion. Based on these nominal estimates the size of the UK economy would appear to have grown some 122 times which is the equivalent of growing by 8.1 per cent each year. However, some of this increase relates not to the volume of output but to the prices of the goods and services produced. It is for this reason that when analysing economic growth we ordinarily look at constant-price or real estimates of GDP. Such estimates effectively show what GDP would have been if prices had remained at the levels of a chosen year known as the base year. The base year now being used in the UK is 2008.

GDP at constant 2008 prices in 2010 is estimated at £1.40 trillion as compared with £314.5 billion in 1948. The real GDP figures reveal that the volume of UK output increased not by a factor of 122 but by a factor of 4.44; this is the equivalent to growth of 2.4 per cent each year.

The nominal GDP estimates for each year from 1948 up to 2010 rise with only one exception: 2009. In 2009, nominal GDP fell by 2.8 per cent. However, over the same period, real GDP fell during seven of the years. What this tells us, is that in six of the seven years, price increases were enough to offset falls in the volume of output such that nominal GDP increased. However, in 2009, the average price of the economy’s output, which is measured by the GDP deflator, rose by a just a little under 1.7 per cent, while the volume of output and, hence, real GDP, fell by almost 4.4 per cent.

The real annual GDP numbers estimate that the volume of UK output declined both in 2008 and 2009. In 2008 output is thought to have fallen by 1.1 per cent, while in 2009, as we have just seen, it fell by 4.4 per cent. The last time the UK experienced two consecutive annual (yearly) falls in output was in 1980 and 1981 when output fell by 2.1 per cent and 1.3 per cent respectively.

If we want to identify recessions then yearly GDP numbers will not do, rather, we need to use quarterly GDP numbers. This is because we are looking for two consecutive quarters where real GDP (output) declined. The revised GDP data show that the UK experienced five consecutive quarterly falls in real GDP in the late 2000s. We went into recession in Q2 of 2008 and came out in Q3 of 2009. As a result, real GDP was 7 per cent lower than before the UK economy entered recession. The previous recession, from Q3 of 1990 to Q3 of 1991 (5 quarters), saw UK output fall by 2.5 per cent. Between these two recessions the UK experienced 66 consecutive quarters of economic growth during which time the revised estimates show that the average annual rate of growth was 3 per cent. Compared with the recession of 2008/09, the next deepest recession in recent times occurred between Q1 of 1980 and Q1 of 1981 (5 quarters) when output fell by 4.7 per cent. In other words, these figures help to illustrate the extraordinary depth of the 2008/9 recession.

At its meeting on 26 October, the eurozone countries agreed on a deal to tackle the three problems identified in Part A of this blog:

1. Making the Greek debt burden sustainable
2. Increasing the size of the eurozone bailout fund to persuade markets that there would be sufficient funding to support other eurozone countries which were having difficulties in servicing their debt.
3. Recapitalising various European banks to shield them against possible losses from haircuts and defaults.

The following were agreed:

1. Banks would be required to take a loss of 50% in converting existing Greek bonds into new ones. This swap will take place in January 2012. Note that Greek debt to other countries and the ECB would be unaffected and thus total Greek debt would be cut by considerably less than 50%.

2. The bailout fund (EFSF) would increase to between €1 trillion and €1.4 trillion, although this would be achieved not by direct contributions by Member States or the ECB, but by encouraging non-eurozone countries (such as China, Russia, India and Brazil) to buy eurozone debt in return for risk insurance. These purchases would the form the base on which the size of the fund could be multiplied (leveraged). There would also be backing from the IMF. Details would be firmed up in November.

3. Recapitalising various European banks to shield them against possible losses from haircuts and defaults. About 70 banks will be required to raise an additional €106.4 billion by increasing their Tier 1 capital ratio by 9% by June 2012 (this compares with the Basel III requirement of 6% Tier 1 by 2015).

On the longer-term issue of closer fiscal union, the agreement was in favour of achieving this, along with tight constraints on the levels of government deficits and debt – a return to something akin to the Stability and Growth Pact.

On the issue of economic growth, whilst constraining sovereign debt may be an important element of a long-term growth strategy, the agreement has not got to grips with the short-term problem of a lack of aggregate demand – unless, of course, the relief in markets at seeing a solution to the debt problem may boost business and consumer confidence. This, in turn, may provide the boost to aggregate demand that has been sadly lacking over the past few months.

Certainly if the reaction of stock markets around the world are anything to go by, the recovery in confidence may be under way. The day following the agreement, the German stock market index, the Dax, rose by 6.3% and the French Cac index rose by 5.4%.

With all the doom and gloom of recent economic data, including rising inflation and higher unemployment, there’s finally a small speck of light and that’s in the form UK retail sales. The latest data from the ONS suggests that sales in the UK in September were higher than previously forecast and reversed the 0.4% decline we saw in August. A big contributing factor to this positive data was a boost to online sales, but this small glimmer of hope is unlikely to be sufficient to keep the economy going – unless sales keep rising, we are unlikely to see any significant increase in economic growth.

The data, while positive, is still unlikely to have any impact on economic policy. The minutes from the Monetary Policy Committee showed that there was unanimous support for further quantitative easing, as the threat of weak growth and financial instability and uncertainty remains. An economist from Barclays Capital said:

‘We don’t think the recent strong growth in monthly sales is likely to be sustained…The environment for retailers is likely to remain challenging as consumer spending remains depressed driven by low confidence and slow earnings growth.’

The data from September is positive, but it does little to offset the decline in sales seen in August. It was revised down from 0.2% to 0.4% – some blame the hot weather, which discouraged consumers from hitting the high streets in preparation for the winter. The key data to look out for will be sales figures for the next few months. Only then will we have more of an indication about exactly which direction the economy is moving in. The following articles consider this latest economic data.

With the UK economy already struggling, the atmosphere in the financial sector has just a bit moodier, as Moody’s have downgraded the credit rating of 12 financial firms in the UK, including Lloyds Banking Group, Royal Bank of Scotland and Nationwide. The change in credit rating has emerged because of Moody’s belief that the UK government was less likely to support these firms if they fell into financial trouble. It was, however, emphasized that it did not “reflect a deterioration in the financial strength of the banking system.” The same can not be said for Portugal, who has similarly seen nine of their banks being downgraded due to ‘financial weakness’. George Osborne commented that it was down to the government no longer guaranteeing our largest banks, but he also said:

“I’m confident that British banks are well capitalised, they are liquid, they are not experiencing the kinds of problems that some of the banks in the eurozone are experiencing at the moment.”

Lloyds Banking Group and Royal Bank of Scotland both saw falls in their shares following their downgraded credit rating. Other banks, including Barclays also saw their shares fall, despite not being downgraded. Perhaps another indication of the interdependence we now see across the world. In interviews, George Osborne has continued to say that he believes UK banks are secure and wants them to become more independent to try to protect taxpayer’s money in the event of a crisis. Moody’s explained its decision saying:

“Moody’s believes that the government is likely to continue to provide some level of support to systemically important financial institutions, which continue to incorporate up to three notches of uplift…However, it is more likely now to allow smaller institutions to fail if they become financially troubled. The downgrades do not reflect a deterioration in the financial strength of the banking system or that of the government.”

The above comment reflects Moody’s approach to downgrading UK banks – not all have seen the same credit rating cuts. RBS and Nationwide have gone down 2 notches, whilst Lloyds and Santander have only gone down by 1 notch. Markets across the world will continue to react to this development in the UK financial sector, so it is a story worth keeping up to date with. The following articles consider the Moody environment.

The National Minimum Wage is a rate applied to most workers in the UK and is their minimum hourly entitlement. For adults over the age of 21, it has recently been increased to £6.08 – 15p rise. Rises have also been seen for 18-20 year olds, 16 and 17 year olds and apprentices. Undoubtedly this is good news for workers receiving the minimum wage, but what does it mean for firms and national unemployment data?

Market wages are determined by the interaction of the demand and supply of labour and when they are in equilibrium, the only unemployment in the economy will be equilibrium unemployment, namely frictional or structural. However, when the wage rate is forced above the equilibrium wage rate, disequilibrium unemployment may develop. At a wage above the equilibrium the supply of labour will exceed the demand for labour and the excess is unemployment. Furthermore, firms are already facing difficult times with the economic climate: sales remain relatively low, but costs are still high. By increasing the national minimum wage, firms will face higher labour costs and this may discourage them from taking on new workers, but may also force them into laying off existing workers.

It is hoped that the size of the increases will help low paid workers, as costs of living continue to rise, but won’t cause firms to reduce their labour force. This is one reason, in particular, why the increase in the minimum wage for young workers is smaller than that for adults. Youth unemployment is relatively high and so it is essential that firms keep these workers on, despite their increased costs.

Although the TUC has welcomed the increases in the National Minimum Wage, saying they will benefit some 900,000 workers, the General Secretary of Unison has said that it isn’t high enough.

“The rise to £6.08 is a welcome cushion, but with the price of everyday essentials such as food, gas and electricity going up massively, it won’t lift enough working people out of the poverty trap.”
