Category: Economics: Ch 15

The latest growth data for the UK is somewhat difficult to interpret. It’s positive, but not that positive. The Conservatives say it shows that the economy is moving in the right direction. Labour suggests it is evidence that the Coalition’s policies are not working. With a return to positive growth, the UK has avoided the triple dip recession and here we take a closer look at the economic performance of other key nations.

In the final quarter of 2012, the US economy grew at 0.4%, but in the 3 months to March 2013, economic growth in America picked up to 2.5%. Consumer spending significantly increased, growing at an annualized rate of 3.2%, according to the Commerce Department. This figure helped boost the growth rate of the US economy, as consumer spending accounts for around two thirds of economic activity.

However, the growth figure was lower than expected, in part due to lower government spending. Furthermore, there are suggestions that the positive consumer spending figures are merely a positive blip and spending will fall as the US economy moves through 2013.

If this does prove to be the case in the USA, it will do little to further boost UK economic growth, which was recorded at 0.3% for the first 3 months of 2013. The Chancellor has said that the growth figures are encouraging and are evidence that the government’s policies are working.

Today’s figures are an encouraging sign the economy is healing … Despite a tough economic backdrop, we are making progress. We all know there are no easy answers to problems built up over many years, and I can’t promise the road ahead will always be smooth, but by continuing to confront our problems head on, Britain is recovering and we are building an economy fit for the future.

While the USA and UK have recorded positive growth, expectations of growth throughout Europe remain uncertain. Spain has revised its forecasts downwards for 2013, expecting the economy to shrink by over 1%. Even after 2013, growth is expected to remain very weak, forecast to be 0.5% in 2014 and 0.9% in 2015. To make matters worse, Spain’s unemployment continues to move in the wrong direction, with data for the first 3 months of 2013, recording an unemployment rate of 27.2% – the highest on record.

However, it’s not just Spanish unemployment that is on the rise. Figures for March show that in France, 3.2 million people were out of work, a 1.2 % rise compared to February. In the UK, 2.56 million people were recorded as unemployed, representing just under 8% of the working population. The German economy continues to outperform its European partners, but eurozone growth continues to look weak for the rest of 2013.

Despite much bad news in Europe, growth in other parts of the world remains buoyant. South Korea has recorded economic growth that is at its highest level in 2 years. Economic growth was just under 1%, but construction and investment both increased, perhaps a sign of an economy starting its recovery.

The Chinese economy has seemed relatively unaffected by the economic downturn, yet its economic growth has slowed. Averaging over 10% per annum for the last decade, the growth for January – March 2013 was only 7.7%. This is a decline on the previous 3 months and is lower than expected. If the Chinese economy does begin to slow (relatively speaking), this could present the global economic recovery with an unwelcome obstacle.

Many Western economies are reliant on exports to boost their growth figures and with such high demand in China, this is a key export market for many countries. If the Chinese economy continues to slow, consumer spending may even fall and this could mean a reduction in Chinese imports: that is, a reduction in other countries’ exports to China. However, for China’s competitors, the news is better, as with China’s move from a low to middle-income country, other countries will now see an opportunity to grasp a competitive advantage in the production of cheaper products. David Rees from Capital Economics said:

Trade data show that Chinese imports of commodities, and industrial metals in particular, have been falling in recent months … That is bad news for those emerging markets in Latin America, the Middle East, and Africa that predominately export commodities to China. It is not all bad news … To the extent that China’s structural slowdown reflects its transition from low to middle-income status, opportunities will present themselves for other EMs as China moves up the value chain. We are particularly upbeat on the manufacturing-based economies of South East Asia, along with Mexico, Poland, and Turkey.

News is better in Japan, where growth forecasts have been raised to 2.9% over the same period and the economy is expected to grow by 1.5% throughout both 2013 and 2014. Furthermore, suggestions that inflation may also reach 0.7% have boosted confidence. This might be the end of Japan’s troubles with deflation.

So, we have something of a mixed picture across the world, although the IMF predicts a global rate of growth of 3.5% for 2013, which would be an improvement on 2012 figures. The following articles consider the global situation.

An excellent learning exercise for students of economics is to take a journal article that uses data to model the economy and then try to replicate the authors’ results. You may well be given an assignment like this in future years of your degree.

One such exercise is used on the University of Massachusetts Amherst’s doctoral programme in economics. Thomas Herndon is a student on that degree and chose to examine a well-known and highly influential paper, Growth in a Time of Debt by Carmen Reinhart then of the University of Maryland and Kenneth Rogoff of Harvard University and former chief economist of the IMF. Professors Reinhart and Rogoff used new data on 44 countries spanning about 200 years.

A key finding of their paper, published in 2010 in the American Economic Review Papers and Proceedings, is that once a country’s government debt exceeds 90% of GDP, growth rates fall considerably: the median across countries by about 1% and the mean considerably more.

The paper has been hugely influential. It has been used to justify the austerity programmes being pursued in many countries, including the UK and the eurozone. Cutting the government deficit to GDP ratio, and ultimately the government debt to GDP ratio, has been seen as a way of achieving higher growth over the longer term, and justifies the adverse effect on short-term growth from the dampening of aggregate demand.

Well, this seemed an interesting paper for Thomas Herndon to examine, and he was keen to show just how Reinhart and Rogoff’s data led to their conclusions. But try as he might, he could not replicate their results. His initial reaction was to think he had made an error, but each time he checked he came back with the same conclusion: they must have made errors in their calculations.

His supervisor at Amherst, Professor Michael Ash, after Thomas had checked and checked again, realised that something was wrong. He encouraged Thomas to write to Reinhart and Rogoff to request sight of their dataset. They duly obliged and it was then that Thomas spotted various errors. These are explained in the articles below, but the overall effect was to alter the conclusion. Although high debt may undermine growth to some extent, the effect is much less than Reinhart and Rogoff concluded, and there are several exceptions to this rule.

On 15 April 2013, Thomas, along with his supervisor, Michael Ash and his colleague, Robert Pollin, published a response to the Reinhart and Rogoff paper. In the abstract to their paper, Does High Public Debt Consistently Stifle Economic Growth? A Critique of Reinhart and Rogoff they state that:

… coding errors, selective exclusion of available data, and unconventional weighting of summary statistics lead to serious errors that inaccurately represent the relationship between public debt and GDP growth among 20 advanced economies in the post-war period. They find that when properly calculated, the average real GDP growth rate for countries carrying a public-debt-to-GDP ratio of over 90 percent is actually 2.2 percent, not –0:1 percent as published in Reinhart and Rogoff. That is, contrary to RR, average GDP growth at public debt/GDP ratios over 90 percent is not dramatically different than when debt/GDP ratios are lower.

The authors also show how the relationship between public debt and GDP growth varies significantly by time period and country. Overall, the evidence we review contradicts Reinhart and Rogoff’s claim to have identified an important stylized fact, that public debt loads greater than 90 percent of GDP consistently reduce GDP growth.

So could this be you in the future? Will you take a famous paper and, by re-examining and reworking the data, find that its conclusions are wrong? Could you end up changing the world? Exciting stuff!

Unemployment is a key macroeconomic objective for governments across the world. The unemployment rate for the UK now stands at 7.9% according to the ONS, which recorded 2.56 million people out of work. But why is unemployment of such importance? What are the costs?

The economy is already in a vulnerable state and with unemployment rising by 70,000 people between December and February 2013, the state of the economic recovery has been questioned. Indeed, following the news of the worsening unemployment data, the pound fell significantly against the dollar, suggesting a lack of confidence in the British economy.

Although the increase in the number of people out of work is concerning, perhaps of more concern should be the number of long-term unemployed. The ONS suggests that more than 900,000 have now been out of work for more than a year. Not only does this pose costs for the individual in terms of lost earnings and skills, but it also imposes costs on friends and family and the wider economy. (Click here for a PowerPoint of the first chart, which shows the percentage of unemployed people out for work longer than 12 months.)

The chief executive of the Prince’s Trust focused on the costs of youth unemployment in particular, saying:

Thousands of these young people are long-term unemployed, often facing further challenges such as poverty and homelessness. We must act now to support these young people into work and give them the chance of a better future.

(Click here for a PowerPoint of the second chart, which shows how much higher the unemployment rate is for young people aged 18 to 24 than it is for the working age population as a whole.)

Furthermore, with so many people unemployed, we are operating below full-employment and thus below our potential output. Furthermore, the longer people are out of work, the more likely it is that they will lose their skills and thus require re-training in the future or find that there are now fewer jobs available to them based on their lower skill level.

In addition to this there are monetary costs for the government through lower tax receipts, in terms of income tax, national insurance contributions and even VAT receipts. With more people unemployed, the numbers claiming various unemployment-related benefits will rise, thus imposing a further cost on the government and the taxpayer. Another cost to the government of this latest data is likely to be the expectations of the future course of the economy. Numerous factors affect business confidence and unemployment data is certainly one of them. The concern is that business confidence affects many other variables as well and until we receive more positive data, the economy recovery is likely to remain uncertain. The following articles consider this topic.

Adverts are increasingly diverse, ranging from families using various products and promoting their qualities, to a gorilla drumming, a horse dancing and a monkey drinking tea! But, how important is advertising to a product’s brand. Does it have a positive effect on sales and profitability?

The key role of advertising is to sell more products and many firms spend a huge amount on advertising campaigns. Indeed, over £16bn was spent on advertising in 2012. Given that the economy is still vulnerable and many firms have seen their sales and profits decline, this is a huge amount. Procter & Gamble spent over £200 million, British Sky Broadcasting spent £145 million and Tesco spent £114 million in 2011.

Advertising increases consumer awareness of the product and its features, but also actively aims to persuade people to purchase the product. By differentiating the product through adverts a company aims to shift the demand curve to the right and also make it more inelastic, by persuading customers that there are no (or few) close substitutes.

Since the start of the economic downturn in 2008, advertising expenditure has fallen, as companies have seen a decline in their budgets. From a high of £18.61 billion in 2004, the Advertising Association found that it fell to £14.20 billion in 2009 at constant 2008 prices. In the last few years, advertising expenditure has remained at around £14.5 billion. But, is cutting back on advertising a sensible strategy during a recession? Of course budgets are tight for both firms and consumers, but many suggest that media-savvy firms would actually benefit from maintaining their advertising. By doing so firms could take advantage of weaker competitors by increasing their market share and establishing their brand image in the long run.

It’s also important to consider another link between economic growth and advertising. Research suggests that advertising can be an important factor for economic growth. A three-year study undertaken by the Advertising Association and Deloitte, commencing in January 2013 suggests that for every £1 spent on advertising in the UK, £6 is generated for the wider economy. Based on these predictions, the estimated £16bn that was spent on ad campaigns in 2011 added over £100 billion to the UK’s GDP.

So, perhaps encouraging more advertising is the answer to the UK’s economic dilemma. This is certainly the opinion of Matt Barwell, the consumer marketing and innovation director of Diageo Western Europe, who said:

People fundamentally believe in advertising but a lot of the conversation focuses on negative elements. People rarely get the opportunity to talk about the positive role advertising plays in terms of wealth creation, exports and the social benefits that it provides. These are all things that many of us take for granted.

If private firms can therefore be encouraged to boost their marketing campaigns, jobs may be created, demand for products will rise and with the help of the multiplier, the economy may strengthen. Advertising has both pros and cons and opinions differ on what makes a good advert. But, whatever your opinion of the role of advertising, it is certainly an important aspect of any economy. The following articles take a view of advertising.

Each month the accountancy firm BDO publishes its Business Trends Indices. These indices “are ‘polls of polls’ that pull together the results of all the main UK business surveys”. The latest report shows that the January 2013 Optimism Index was its lowest since the report began 21 years ago.

The Optimism Index predicts business performance two quarters ahead. In January 2013 it was 88.9. The way the index is constructed, a reading of 95 or more suggests that firms are optimistic about business performance. Clearly, they were pessimistic.

Although there was an increase in hiring intentions, firms were still predicting a fall in output. The indices for optimism, employment and output are shown in the chart. (Click here for a PowerPoint.)

As Peter Hemington, Partner, BDO LLP, commented:

In spite of a strengthening Labour Market, business confidence continues to weaken, and improved hiring intentions are not translating into growth plans. It seems the damaging effects on businesses of five years’ zigzagging economic growth, has left them wary of making concrete plans for expansion and resigned to the ‘new normal’ of economic stagnation.

To end this cycle, it is imperative that the Government implements plans to expedite growth. Without growth incentives, we will continue to see UK businesses reluctant to invest and expand, which poses a grave threat to the UK’s economic recovery.

The following articles comment on the gloomy mood of business and on its implications for output and investment. They also look at the implications for government policy.
