Category: Essentials of Economics: Ch 09

Growing inequality of income and wealth is a common pattern throughout the world. In the boom years up to 2008, the rich got a lot richer, but at least those on low incomes generally saw modest rises in their incomes. Since 2008, however, the continually widening gap between rich and poor has seen the poor and many on middle incomes getting absolutely poorer.

The problem is particularly acute in the USA. Indeed, in his 2012 State of the Union address, President Obama said that it was the ‘defining issue of our time.’

No challenge is more urgent. No debate is more important. We can either settle for a country where a shrinking number of people do really well, while a growing number of Americans barely get by. Or we can restore an economy where everyone gets a fair shot, everyone does their fair share, and everyone plays by the same set of rules.

The good news for the poor in the USA is that at last their incomes have stopped falling, thanks to stronger economic growth. But their share of the growth in GDP is tiny. As The Economist article states:

The main message is a grim one. Most of the growth is going to an extraordinarily small share of the population: 95% of the gains from the recovery have gone to the richest 1% of people, whose share of overall income is once again close to its highest level in a century. The most unequal country in the rich world is thus becoming even more so.

Apart from the ethical question of whether it is desirable for a society, already highly unequal, to become even more so, there is the question of whether this growth in inequality threatens economic recovery. Joseph Stiglitz argues that the rich have a low marginal propensity to consume and that this is threatening recovery.

Then there is the question of investment. Because most Americans have not seen any significant rise in incomes, it is easy for them to believe that the country cannot afford to invest more. And certainly it is difficult to persuade people that higher taxes are warranted to fund education, infrastructure or research.

The following articles consider the problem and its implications and look at various policy alternatives.

A constant feature of the UK economy (and of many other Western economies) has been record low interest rates. Since March 2009, Bank Rate has stood at 0.5%. Interest rates have traditionally been used to keep inflation on target, but more recently their objective has been to stimulate growth. However, have these low interest rates had a negative effect on the business environment?

Interest rates are a powerful tool of monetary policy and by affecting many of the components of aggregate demand, economic growth can be stimulated. This low-interest rate environment is an effective tool to stimulate consumer spending, as it keeps borrowing costs low and in particular can keep mortgage repayments down. However, this policy has been criticised for the harm it has been doing to savers – after all, money in the bank will not earn an individual any money with interest rates at 0.5%! Furthermore, there is now a concern that such low interest rates have led to ‘zombie companies’ and they are restricting the growth potential and recovery of the economy.

A report by the Adam Smith Institute suggests that these ‘zombie companies’ have emerged in part by the low-interest environment and are continuing to absorb resources, which could otherwise be re-allocated to companies with more potential, productivity and a greater contribution to the economic recovery. During a recession, there will undoubtedly be many business closures, as aggregate demand falls, sales and profits decline until eventually the business becomes unviable and loans cannot be repaid. Given the depth and duration of the recent recessionary period, the number of business closures should have been very large. However, the total number appears to be relatively low – around 2% or 100,000 and the report suggests that the low interest rates have helped to ‘protect’ them.

Low interest rates have enabled businesses to meet their debt repayments more easily and with some banks being unwilling to admit to ‘bad loans’, businesses have benefited from loans being extended or ‘rolled over’. This has enabled them to survive for longer and as the report suggests, may be preventing a full recovery. The report’s author, Tom Papworth said:

Low interest rates and bank forbearance represent a vast and badly targeted attempt to avoid dealing with the recession. Rather than solving our current crisis, they risk dooming the UK to a decade of stagnation … We tend to see zombies as slow-moving and faintly laughable works of fiction. Economically, zombies are quite real and hugely damaging, and governments and entrepreneurs cannot simply walk away.

The problem they create is that resources are invested into these companies – labour, capital, innovation. This creates an opportunity cost – the resources may be more productive if invested into new companies, with greater productive potential. The criticism is that the competitiveness of the economy is being undermined by the continued presence of such companies and that this in turn is holding the UK economy back. Perhaps the interest rate rise that may happen this time next year may be what is needed to encourage the re-allocation of capital. However, a 0.5 percentage point rise in interest rates would hardly be the end of the world for some of these companies. Perhaps a more focused approach looking at restructuring is the key to their survival and the allocation of resources to their most productive use. The following articles and the report itself consider the case of the trading dead.

Compared with pre-financial crisis levels, the British pound is significantly weaker when measured against a basket of foreign currencies. In this blog we provide a further update of Appreciating a depreciating pound which was published back in early December 2012. The significance of the depreciation should be seen in the context of the UK as an open, island-economy where the ratio of exports to GDP in 2012 was close to 32%.

The competitiveness of our exports is, in part, affected by the exchange rate. Floating exchange rates are notoriously volatile. For example, some of the articles below show how sensitive the British pound can be latest news on the economy. However, since the autumn of 2007 we have observed a significant depreciation of the UK exchange rate. A depreciation helps to make our exports more competitive abroad and can potentially boost aggregate demand.

Rather than simply focus on bilateral exchange rates and so at the British pound separately against other foreign currencies, we can estimate an average exchange rate against a whole bundle of currencies. The average rate is calculated by weighting the individual exchange rates by the amount of trade between Britain and the other countries. This trade-weighted exchange rate is known as the effective exchange rate.

In analysing the competitiveness of the exchange rate, we can go one step further and adjust for the average (domestic currency) price of our exports relative to the average (foreign currency) price of those goods we import. Therefore, as well as the nominal (actual) effective exchange rate we can calculate a real effective exchange rate. If the average price of our exports rises relative to the average price of imports, the real effective exchange rate rises relative to the nominal rate. It means that we are able to obtain a larger volume of imports from selling a given volume of exports.

The chart shows the nominal (actual) and real effective exchange rate for the British pound since 2001. The chart shows clearly how from the autumn of 2007 the effective exchange rate fell sharply both in nominal and real terms.

Over the period from July 2007 to January 2009 the nominal effective exchange rate fell by 26.8 per cent while the real effective exchange rate fell by 26.6 per cent. In other words, the British pound depreciated more than one-quarter over an 18-month period. In comparison, the American dollar rose by 5.3 per cent in nominal terms and by 1.9 per cent in real terms. (Click here to download a PowerPoint of the chart.)

If we move the clock forward, we observe an appreciation of the British pound between July 2011 and September 2012. Over this period, the British pound appreciated by 7.0 per cent in nominal terms and by 7.3 per cent in real terms. However, this appreciation had effectively been wiped-out when by March 2013 the nominal rate had depreciated by 6.1 per cent and by 5.6 per cent in real terms. Subsequently, there has been a slight appreciation once more. As of September, the nominal rate had risen by 4.5 per cent and the real rate by 4.8 per cent.

While, as recent figures help to demonstrate, the British pound continues on its roller-coaster ride, there has been a very marked depreciation since the giddy-days prior to the financial crisis. The facts show that when comparing the effective exchange rate in September 2013 with July 2007 the British pound was 21.8 per cent lower in nominal terms and 18.3 per cent in real terms. Over the same period, the US dollar, for example, was only 1.3 per cent lower in nominal terms and 6.1 per cent in real terms. This constitutes a major competitive boost for our exporters. Nonetheless, there remain uncertainty about just how much British exporters can take advantage of this, the amount that it will boost British growth and the impact it will make on the country’s chronic balance of trade deficit in goods which was close to 7 per cent of GDP in 2012.

HS2 has been a controversial topic for some time now. Between the disruption it would cause to countless neighbourhoods and the protests that have emerged and the debate about the cost effectiveness of the project, it’s been in the news a fair amount. The transport network in the UK needs improving, not only for businesses located here, but also to encourage more investment into the country. HS2 is one of the solutions offered.

The latest estimate for the cost of HS2 is over £40 billion. However, many suggest that the benefits HS2 will bring do not cover the full costs. Furthermore, as noted above, other concerns include the disruption that it will bring to countless households who will be living along the proposed routes. Cost benefit analysis have been carried out to determine the viability of the project, but they are invariably difficult to do. As they involve determining all of the private and social costs and benefits and putting a monetary estimate onto them, there will inevitably be factors that are over-looked, under-estimated or over-estimated. The suggestions here are that the costs have been under-estimated and the benefits over-estimated.

In September, KPMG produced a report that estimated the overall benefit to the UK economy would be a boost to growth of 0.8%, which would benefit many businesses and communities. The British Chambers of Commerce said:

Business communities in dozens of cities and towns, from many parts of the UK, remain strongly supportive of HS2.

The railway network is also approaching full capacity and this is one of the reasons why HS2 has been proposed. A government source said:

We need to do something because our railways are nearly full, but the alternative to HS2 is a patch and mend job that would cause 14 years of gridlock, hellish journeys and rail replacement buses … The three main routes to the north would be crippled and the economy would be damaged.

However, this report has faced criticism, in particular because it ignored a variety of supply-side constraints and because they argue it would be more effective to simply update the existing network. However, a new government-commissioned report has suggested that this alternative to HS2 would involve 14 years of weekend route closures and much longer journey times. However, those in favour of updating existing routes have said that this new report commissioned by the government is ‘a complete fabrication’. Hilary Wharf of the HS2 Action Alliance commented:

This government-funded report is a complete fabrication. The main alternative to HS2 involves longer trains and reduced first-class capacity to provide more standard class seats…No work is required at Euston to deliver the necessary capacity increase. Work is only required at three locations on the WCML [West Coast Main Line], and this is comparable to the work being carried out on the route at present.

The debate regarding HS2 will continue for the time being and it is just another area that is fuelling the political playing field. Whatever is done, the rail network certainly requires investment, whether it is through HS2 or upgrades to the existing routes. The following reports and articles consider the latest developments and controversy regarding HS2.

The latest preliminary GDP estimates for 2013 Q3 suggest that the economy’s output (real GDP) expanded by 0.8 per cent following on the back of a 0.7 per cent increase in Q2. Growth was observed across the main industrial sectors with the important service sector growing by 0.7 per cent. While the output of the service sector is now 0.5 per cent higher than its 2008 Q1 peak, the total output of the economy remains 2.6 per cent below its 2008 Q1 peak.

The volatility of growth underpins the idea of business cycles and on occasions results in recessions. Today’s release needs to be set in the context of this volatility and in the context of 2008/9 recession which saw output fall by 7.2 per cent. UK output peaked in 2008 Q1 (£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 estimates of real GDP for 2011 Q4 and 2012 Q1 are identical at £376.462 billion (at 2010 prices). Previous revisions have seen the 2012 Q1 growth number revised up so that a further recession resulting in a double-dip recession no longer appears in the figures.

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 an economy that grew by 0.4 per cent in 2013 Q1 (to £377.301 billion at 2010 prices), by 0.7 per cent in 2013 Q2 (to £379.780 billion at 2010 prices) and by 0.8 per cent in 2013 Q3 billion (to £382.818 billion at 2010 prices). Compared with 2012 Q3, the output of the UK economy in 2013 Q2 is 1.5 per cent higher.

Chart 1 helps to put the recent growth numbers into an historical context. It shows the quarterly change in real GDP since the 1980s. From it, 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 of the chart.)

Chart 2 scratches a little below the surface by looking at output by the four principal industrial types. The interesting finding is that the output of the service sector has now risen above its 2008 Q1 peak. In 2013 Q3 output is 0.5 per cent larger. By contrast, the other three sectors remain smaller than in 2008 Q1. Agriculture, forestry and fisheries is 5.9 per cent smaller, construction 14.3 per cent smaller and production (including manufacturing) is 14.6 per cent smaller. (Click here to download a PowerPoint of the chart.)

With today’s release, quarterly growth now averages –0.11 per cent since 2008 Q2. If we take the series back to the mid 1950s when it began, the average quarterly rate of growth is 0.64 per cent which is equivalent to an annual rate of increase of 2.57 per cent. While today’s news is encouraging it remains important to keep it in perspective and to ensure that growth is sustainable and built on firm foundations.
