Category: Economics for Business: Ch 26

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.

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.

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.”

No, bonfire night hasn’t been moved, but the 30th November could certainly be a day to remember. This day has been ‘selected’ by Unions for a nationwide day of action in response to government plans to increase workers’ pension contribution. The action would undoubtedly lead to massive disruption to public services across the UK and if an agreement is not reached with Ministers, we are likely to see further days of industrial action. In the words of the TUC boss, Brendan Barber, if no agreement is forthcoming, there will be ‘the biggest trade union mobilisation for a generation’.

The so-called pensions crisis has been an ongoing saga with seemingly no end in sight. As the UK population gets older, the strain on the state pension will continue to grow. The dependency ratio has increased – there are more and more pensioners being supported by fewer and fewer adults of working age. If the level of benefits is to be maintained, workers must either work for longer or make larger contributions to make up the deficit.

Plans are already in motion to increase the retirement age, but this in itself will not be sufficient. If pension contributions do increase, workers will undoubtedly find themselves worse off – a larger proportion of their gross income will be taken and hence net incomes will be lower. With less disposable income, consumer expenditure will fall, and given that consumption is the largest component of aggregate demand, the economy will take a hit. This is even more of a concern given the pay freezes we have already seen, together with rising inflation. People’s purses will get squeezed more and more, So, while raising pension contributions may help plug the pensions deficit, it could spell trouble for the economic prospects of the UK economy.

In addition to the potential longer term effects, there will also be a significant short term effect, namely, the loss of output on the day of the strike action. If workers are absent, the company will produce less than their potential and in some cases, the lost output can never be regained. If the postal workers go on strike, businesses may find packages go undelivered, customers experience delays, bills are not paid and so on. In all, strike action on the scale that is planned will have an impact on everyone, so it is in the interests of the economy for some sort of agreement to be reached. As Mr. Barber said:

‘If there’s no progress, then potentially we will see very widespread industrial action across the public services’

  2. What is meant by the dependency ratio? What action could be taken to reduce it? For each type of action, think about the costs and benefits.
  3. If pension contributions do increase, explain how workers will be affected. How will this affect each of the components of aggregate demand?
  4. Based on your answer to the above questions, what is likely to be the impact on the government’s macroeconomic objectives?
  5. What other action, besides striking, could unions take? Is it likely to be as effective? Do you think strikes are a good thing?
  6. Illustrate on a diagram the effect of a trade union entering an industry. How does it normally affect equilibrium wages and employment?

Stock markets have been plummeting. The FTSE 100 index was 6055 on 7 July 2011; by 10 August, it was 17% lower at 5007. Since then it has risen as high as 5418, but by 13 September was down to 5092. Other stock markets have fared worse. The French index fell 30% between early July and September 13, and the German DAX index fell 32% over the same period.

These falls in share prices reflect demand and supply. Investors are worried about the future of the eurozone and the health of the European economy as Greek default looks more and more likely and as the debts of various other European countries, such as Portugal, Ireland and Spain, seem increasingly unsustainable in an environment of sluggish economic growth. They are also worried about high public-sector debt in the USA and the likelihood that global recovery will peter out.

The ‘bear’ market (falling share prices) reflects increased selling of shares and a lack of demand. Not only are investors worried about the global economy, they are also speculating that share prices will fall further, thereby compounding the falls (at least until the ‘bottom’ is reached).

But why have share prices fallen quite so much? And does it matter to the general public that this is happening? The following articles seek to answer these questions.
