In his 1971 book, Income Distribution, Jan Pen, a Dutch economist, gave a graphic illustration of inequality in the UK. He described a parade of people marching by. They represent the whole population and the parade takes exactly one hour to pass by. The height of each person represents his or her income. People of average height are the people with average incomes – the observer is of average height. The parade starts with the people on the lowest incomes (the dwarfs), and finishes with those on the highest incomes (the giants).
Because income distribution is unequal, there are many tiny people. Indeed, for the first few minutes of the parade, the marchers are so small they can barely be seen. Even after half an hour, when people on median income pass by, they are barely waist high to the observer.
The height is growing with tantalising slowness, and forty-five minutes have gone by before we see people of our own size arriving. To be somewhat more exact: about twelve minutes before the end the average income recipients pass by.
In the final minutes, giants march past and then in the final seconds:
the scene is dominated by colossal figures: people like tower flats. Most of them prove to be businessmen, managers of large firms and holders of many directorships and also film stars and a few members of the Royal Family.
The rear of the parade is brought up by a few participants who are measured in miles. Indeed they are figures whose height we cannot even estimate: their heads disappear into the clouds and probably they themselves do not even know how tall they are.
Pen’s description could be applied to most countries – some with even more dwarfs and even fewer but taller giants. Generally, over the 43 years since the book was published, countries have become less equal: the giants have become taller and the dwarfs have become smaller.
The 2011 Economist article, linked below, uses changes in Gini coefficients to illustrate the rise in income inequality. A Gini coefficient shows the area between the Lorenz curve and the 45° line. The figure will be between 0 and 1 (or 0% and 100%). a figure of 0 shows total equality; a figure of 1 shows a situation of total inequality, where one person earns all the nation’s income. The higher the figure, the greater the inequality.
The chart opposite shows changes in the Gini coefficient in the UK (see Table 27 in the ONS link below for an Excel file of the chart). As this chart and the blog post Rich and poor in the UK show, inequality rose rapidly during the years of the 1979–91 Thatcher government, and especially in the years 1982–90. This was associated with cuts in the top rate of income tax and business deregulation. It fell in the recession of the early 1990s as the rich were affected more than the poor, but rose with the recovery of the mid- to late 1990s. It fell again in the early 2000s as tax credits helped the poor. It fell again following the financial crisis as, once more, the rich were affected proportionately more than the poor.
The most up-to-date international data for OECD countries can be found on the OECD’s StatExtracts site (see chart opposite: click here for a PowerPoint). The most unequal developed county is the USA, with a Gini coefficient of 0.389 in 2012 (see The end of the American dream?), and US inequality is rising. Today, the top 1% of the US population earns some 24% of national income. This compares with just 9% of national income in 1976.
Many developing countries are even less equal. Turkey has a Gini coefficient of 0.412 and Mexico of 0.482. The figure for South Africa is over 0.6.
When it comes to wealth, distribution is even less equal. The infographic, linked below, illustrates the position today in the USA. It divides the country into 100 equal-sized groups and shows that the top 1% of the population has over 40% of the nation’s wealth, whereas the bottom 80% has only 7%.
So is this inequality of income and wealth desirable? Differences in wages and salaries provide an incentive for people to work harder or more effectively and to gain better qualifications. The possibility of increased wealth provides an incentive for people to invest.
But are the extreme differences in wealth and income found in many countries today necessary to incentivise people to work, train and invest? Could sufficient incentives exist in more equal societies? Are inequalities in part, or even largely, the result of market imperfections and especially of economic power, where those with power and influence are able to use it to increase their own incomes and wealth?
Could it even be the case that excessive inequality actually reduces growth? Are the huge giants that exist today accumulating too much financial wealth and creating too little productive potential? Are they spending too little and thus dampening aggregate demand? These arguments are considered in some of the articles below. Perhaps, by paying a living wage to the ‘tiny’ people on low incomes, productivity could be improved and demand could be stimulated.

Lloyds Banking Group has announced that it plans to reduce its labour force by 9000. Some of this reduction may be achieved by not replacing staff that leave, but some may have to be achieved through redundancies.
The reasons given for the reduction in jobs are technological change and changes in customer practice. More banking services are available online and customers are making more use of these services and less use of branch banking. Also, the increasingly widespread availability of cash machines (ATMs) means that fewer people withdraw cash from branches.
And it’s not just outside branches that technological change is impacting on bank jobs. Much of the work previously done by humans is now done by software programs.
One result is that many bank branches have closed. Lloyds says that the latest planned changes will see 150 fewer branches – 6.7% of its network of 2250.
What’s happening in banking is happening much more widely across modern economies. Online shopping is reducing the need for physical shops. Computers in offices are reducing the need, in many cases, for office staff. More sophisticated machines, often controlled by increasingly sophisticated computers, are replacing jobs in manufacturing.
So is this bad news for employees? It is if you are in one of those industries cutting employment. But new jobs are being created as the economy expands. So if you have a good set of skills and are willing to retrain and possibly move home, it might be relatively easy to find a new, albeit different, job.
As far as total unemployment is concerned, more rapid changes in technology create a rise in frictional and structural unemployment. This can be minimised, however, or even reduced, if there is greater labour mobility. This can be achieved by better training, education and the development of transferable skills in a more adaptive labour force, where people see changing jobs as a ‘normal’ part of a career.

In the Blog, A VW recession for the eurozone, as German growth revised down?, we discussed the pessimistic outlook for the eurozone, in part driven by the problems facing the engine of Europe: Germany. While the German government noted that the weak growth figures are due to external factors, it appears as though these external factors are now sending waves through the domestic economy.
Over the past 6 months, German confidence has fallen continuously and now stands at almost its lowest level in 2 years. Think tank data from a survey of 7000 firms in Germany fell from 104.7 to 103.2 for October – the weakest reading since December 2012. Confidence is always a key factor in the strength of an economy, as it affects consumers and businesses. 
Without consumer and business confidence, two key components of aggregate demand are weak and this downward pressure on total spending in the economy depresses economic growth. An economist from Ifo, the think-tank that produced this business climate index, said that firms felt ‘downbeat about both their current situation and the future.’
As confidence continues to decline in Germany, the economic situation is unlikely to improve. Unfortunately, it is something of a vicious circle in that without economic growth confidence won’t return and without confidence, economic growth won’t improve. The industrial sector is crucial to Germany and the data is concerning, according to Chief economist at Commerzbank, Joerg Kraemer:
The latest numbers from the industrial sector are very worrisome…The third quarter was probably worse than expected, the economy may have stagnated at best.
Numerous factors continue to depress the German economy and while negative growth is not expected, estimates for quarterly growth from July to September remain at around 0.3%. As Europe’s largest economy, such low growth rates will be of concern to the rest of the Eurozone and may also bring worry to other countries, such as the US and UK. With growing interdependence between nations, the success of countries such as Germany and Europe as a whole influences the economic situation abroad. Commentators will be looking for any signal that Germany is strengthening in the coming months and an improvement in business confidence will be essential for any prolonged recovery.

Questions
- Why is consumer and business confidence such an important element in explaining the state of an economy?
- Use an AD/AS diagram to illustrate the impact on national output of a decline business confidence. What are the other consequences for the macroeconomic objectives?
- What actions can a government take to boost confidence in an economy?
- If economic growth is weak and confidence is low, is there any point in cutting interest rates as a means of stimulating investment?
- If the eurozone did move back into recession, what could be the possible consequences for countries such as the UK and US?
- How useful are indices that measure business confidence?
Europe’s largest economy is Germany and the prospects and growth figures of this country are crucial to the growth of the Eurozone as a whole. The EU is a key trading partner for the UK and hence the growth data of Germany and in turn of the Eurozone is also essential in creating buoyant economic conditions within our borders. The bad news is that the economic growth forecast for Germany has been cut by the German government.
The German government had previously estimated that the growth rate for this year would be 1.8%, but the estimate has now been revised down to 1.2% and next year’s growth rate has also been revised downwards from 2% to 1.3%. Clearly the expectation is that low growth is set to continue.
Whenever there are changes in macroeconomic variables, a key question is always about the cause of such change, for example is inflation caused by demand-pull or cost-push factors. The German government has been quick to state that the lower growth rates are not due to internal factors, but have been affected by external factors, in particular the state of the global economy. As such, there are no plans to make significant changes to domestic policy, as the domestic economy remains in a strong position. The economy Minister said:
“The German economy finds itself in difficult external waters … Domestic economic forces remain intact, with the robust labour market forming the foundation … As soon as the international environment improves, the competitiveness of German companies will bear fruit and the German economy will return to a path of solid growth … [for this reason there is] no reason to abandon or change our economic or fiscal policy.”
The global picture remains relatively weak and while some economies, including the UK, have seen growth pick up and unemployment fall, there are concerns that the economic recovery is beginning to slow. With an increasingly interdependent world, the slowing down of one economy can have a significant impact on the growth rate of others. If country A begins to slow, demand for imports will fall and this means a fall in the demand for exports of country B. For countries that are dependent on exports, such as Germany and China, a fall in the demand for exports can mean a big decline in aggregate demand and in August, Germany saw a 5.8% drop in exports.
Adding to the gloom is data on inflation, suggesting that some other key economies have seen falls in the rate of inflation, including China. The possibility of a triple-dip recession for the Eurozone has now been suggested and with its largest economy beginning to struggle, this suggestion may become more real. The following articles consider the macroeconomic picture.

In two posts recently, we considered the pessimistic views of Robert Peston about the prospects for the global economy (see Cloudy skies ahead? and The end of growth in the West?). In this post we consider the views of Christine Lagarde, Managing Director of the International Monetary Fund, and Lord Adair Turner, the former head of the Financial Services Authority (FSA) (which was replaced in 2013 by the Financial Conduct Authority and the Prudential Regulation Authority).
Christine Lagarde was addressing an audience at Georgetown University in Washington DC. The first four links below are to webcasts of the full speech and subsequent interviews about the speech. She gives a more gloomy assessment of the global economy than six months ago, especially the eurozone economy and several emerging economies, such as China. There are short- to medium-term dangers for the world economy from political conflicts, such as that between Russia and the West over Ukraine. But there are long-term dangers too. These come from the effects of subdued private investment and low infrastructure spending by governments.
Her views are backed up by the six-monthly World Economic Outlook, published by the IMF on 7 October. There are links below to two webcasts from the IMF discussing the report and the accompanying datasets.
In the final webcast link below, Lord Turner argues that there is a “real danger of a simultaneous slowdown producing a big setback to growth expectations.” He is particularly worried about China, which is experiencing an asset price bubble and slowing economic growth. Other emerging economies too are suffering from slowing growth. This poses real problems for developed countries, such as Germany, which are heavily reliant on their export sector.
