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.

Cutting the budget deficit is a key government objective, but at the moment it seems to be in conflict with another objective, namely economic growth and thereby avoiding a double-dip recession. In order to raise tax revenue and meet the cries for more equity, the 50% tax rate above £150,000 was imposed, affecting some 310,000 people. However, in a recent letter from some top economists to the Financial Times, they called for the scrapping of the top rate of tax. They argue that it is hindering entrepreneurship and encouraging potential top rate tax payers to leave the UK, thereby hindering the economic situation. George Osborne has asked HMRC to evaluate just how effective the top rate of tax has been at generating government revenue.
In contrast to these calls for scrapping this top rate of tax, some of the richest people in the world have said that they would be happy to pay this rate of tax. In the words of Sir Stuart Rose, the ex-boss of Marks and Spencer:
“How would I explain to my secretary that I would pay less tax on my income, which is palpably bigger than hers, when her tax is not going down.”
Those against scrapping the tax argue that it will be ‘monstrously unfair’ and ‘phenomenally immoral’. This, combined with official figure that suggest by 2015/16 the top rate tax will bring in an extra £3.2bn more revenue than had the tax remained at 40%, certainly adds weight to their argument. In total, over the five year period, it is predicted to bring in an extra £12.6bn.
The policy to increase the tax threshold to £10,000 will meet with the critics’ approval, but less so, if it is accompanied by a scrapping of this top rate tax. Furthermore, the government’s coffers will take a significant beating if both of the above occur!
Another option to replace the 50% tax rate is a higher tax on high value homes – the so-called ‘mansion tax’. Whatever happens with taxation, one thing is clear: the government needs to find a way to generate tax revenue, without putting the economy back into recession. If the 50% tax rate encourages people to leave the UK to avoid the tax or to forego entrepreneurship, it will directly be acting as a disincentive. Fewer jobs will be created due to a lack of entrepreneurship, output may be lower and hence growth will not reach its potential. Crucially, the international competitiveness of the UK economy is being badly affected, as it becomes a less attractive place for investment and talented workers. The following articles consider the 50% tax rate and the controversy surrounding it, despite it only being a temporary policy.

The Brazilian economy is an emerging superpower (see A tale of two cities), but even its growth slowed in the second quarter of the year, although the economy still appears to be growing above capacity. In reaction to that latest economic data, the central bank slashed interest rates by 50 basis points to 12%. The Central Bank said:
‘Reviewing the international scenario, the monetary policy committee considers that there has been a substantial deterioration, backed up, for example, by large and widespread reductions to the growth forecasts of the main economic regions.’
Rates had previously been hiked up 5 times in the year to tackle rising inflation, which has been some way above its inflation target. Such tightening policies have become commonplace in many emerging economies to prevent overheating. However, following this reversal of policy, questions have been raised about the independence of the central bank, as some politicians have recently been calling for a cut in rates, including President Rousseff himself. As Tony Volpon at Nomura Securities said:
‘They gave in to political pressure. The costs will likely be much higher inflation and a deterioration of central bank credibility…It has damaged the inflation-targeting regime.’
Many believe the rate cut is premature and the last thing the economy needs given the inflationary pressures it’s been facing. Huge spending cuts have been announced to bring inflation back under control, together with the previous rate rises, so this cut in interest rates to stimulate growth is likely to put more pressure on costs and prices. Only time will tell exactly how effective or problematic this new direction of monetary policy will be.

The growing interdependence of economies has never been more true than over the past few years. The credit crunch began in the US and gradually spread to the rest of the world. As the saying goes, ‘when America sneezes, the world catches a cold’. The US economy is the largest in the world and with such a close relationship to the UK, its economic situation is critical. GDP growth in the first quarter was a mere 0.4% and in the second quarter, it was revised down from the US Commerce Department’s original estimate of 1.3% to just 1%. This was attributed to weaker growth in business inventories, a fall in exports and less spending from the state and local governments. Personal consumption expenditure and exports did rise, but the increase in the former was hardly noticeable (0.4%) and in both cases, the second quarter increase was significantly down on that in the first quarter.
With GDP growth remaining low, there’s not much better news when it comes to US unemployment, which remained at 9.1% from July. It was expected that a further 70,000 jobs would be created in August, but the latest figures suggest that no new jobs were created. It seems that the data on growth and the components of aggregate demand are enough to bring consumer and investor confidence down. Virginie Maisonneuve said:
‘Companies that are overall doing OK are hesitating to hire and invest further, creating some fragility for the economy… We will need some help from the Fed and the government to avoid a recession.’
President Obama is due to make a speech in which he will outline a new plan to boost economic growth. Crucial to this will be restoring confidence, as without it, businesses will not invest, consumers will save rather than spend, jobs will not be created and growth will remain sluggish. This will do nothing to help the still weak economies of Europe. Indeed, following news of the US job situation, stock markets across the world fell, as fears of recession set in. The Dow Jones opened 2% down, the FTSE 100 ended 2.3% down (although this was also affected by a weakening in the construction sector), markets in Germany, France and Spain were down by over 3% and in Italy by over 4%.
