What is the relationship between the degree of inequality in a country and the rate of economic growth? The traditional answer is that there is a trade off between the two. Increasing the rewards to those who are more productive or who invest encourages a growth in productivity and capital investment, which, in turn, leads to faster economic growth. Redistribution from the rich to the poor, by contrast, is argued to reduce incentives by reducing the rewards from harder work, education, training and investment. Risk taking, it is claimed, is discouraged.
Recent evidence from the OECD and the IMF, however, suggests that when income inequality rises, economic growth falls. Inequality has grown massively in many countries, with average incomes at the top of the distribution seeing particular gains, while many at the bottom have experienced actual declines in real incomes or, at best, little or no growth. 
This growth in inequality can be seen in a rise in countries’ Gini coefficients. The OECD average Gini coefficient rose from 0.29 in the mid-1980s to 0.32 in 2011/12. This, claims the OECD, has led to a loss in economic growth of around 0.35 percentage points per year.
But why should a rise in inequality lead to lower economic growth? According to the OECD, the main reason is that inequality reduces the development of skills of the lower income groups and reduces social mobility.
By hindering human capital accumulation, income inequality undermines education opportunities for disadvantaged individuals, lowering social mobility and hampering skills development.
The lower educational attainment applies both to the length and quality of education: people from poorer backgrounds on average leave school or college earlier and with lower qualifications.
But if greater inequality generally results in lower economic growth, will a redistribution from rich to poor necessarily result in faster economic growth? According to the OECD:
Anti-poverty programmes will not be enough. Not only cash transfers but also increasing access to public services, such as high-quality education, training and healthcare, constitute long-term social investment to create greater equality of opportunities in the long run.
Thus redistribution policies need to be well designed and implemented and focus on raising incomes of the poor through increased opportunities to increase their productivity. Simple transfers from rich to poor via the tax and benefits system may, in fact, undermine economic growth. According to the IMF:
That equality seems to drive higher and more sustainable growth does not in itself support efforts to redistribute. In particular, inequality may impede growth at least in part because it calls forth efforts to redistribute that themselves undercut growth. In such a situation, even if inequality is bad for growth, taxes and transfers may be precisely the wrong remedy.

Questions
- Explain what are meant by a Lorenz curve and a Gini coefficient? What is the relationship between the two?
- The Gini coefficient is one way of measuring inequality. What other methods are there? How suitable are they?
- Assume that the government raises taxes to finance higher benefits to the poor. Identify the income and substitution effects of the tax increases and whether the effects are to encourage or discourage work (or investment).
- Distinguish between (a) progressive, (b) regressive and (c) proportional taxes?
- How will the balance of income and substitution effects vary in each of the following cases: (a) a cut in the tax-free allowance; (b) a rise in the basic rate of income tax; (c) a rise in the top rate of income tax? How does the relative size of the two effects depend, in each case, on a person’s current income?
- Identify policy measures that would increase both equality and economic growth.
- Would a shift from direct to indirect taxes tend to increase or decrease inequality? Explain.
- By examining Tables 3, 26 and 27 in The Effects of Taxes and Benefits on Household Income, 2012/13, (a) explain the difference between original income, gross income, disposable income and post-tax income; (b) explain the differences between the Gini coefficients for each of these four categories of income in the UK.
The housing market was at the heart of the 2014 Autumn Statement. Perhaps most eyecatching were the reforms to stamp duty. Stamp Duty is a tax on house purchases. Overnight we have seen the introduction of a graduated system of tax, along the lines of the income tax system – similar to the model to be adopted in Scotland from next April under the Land and Buildings Transactions Tax. For the rest of the UK, there will be five tax bands, including a zero rate band for property values up to £125,000. The total tax liability will be dependent upon the proportion of the value of the property that falls in each taxable band.
But, alongside the Stamp Duty announcement, the Autumn Statement was noteworthy for its references to new build. New build is clearly central to UK housing policy.
The Autumn Statement reaffirmed the government’s wish to see house building play a central role in easing pressures on the housing market. Over the past 40 years or more UK house prices have been characterised by considerable volatility and by a significant real increase. This can be seen clearly in the chart. 
Actual (nominal) house prices across the UK have grown an average rate of 10 per cent per year. Even if we strip out the effect of economy-wide inflation, we are still left with an increase of around 3.5 per cent per year. (Click here to download a PowerPoint of the chart).
The economics point to supply-side problems that mean demand pressures feed directly into house prices. The commitment to build has now seen the announcement of a new garden city near Bicester in Oxfordshire. This is set to provide 13,000 or more new homes. The government has also pledged £100 million to the Ebbsfleet Garden City project to provide the infrastructure and land remediation necessary to bring in more private-sector developers to help deliver an expected 15,000 new homes.
An interesting development in housing policy is the willingness of government to consider being more actively involved itself in house building. The development of former barracks at Northstowe in Cambridgeshire will be spearheaded by the Homes and Communities Agency which will lead on the planning and construction of up to 10,000 new homes. This signals, at least on paper, that government is prepared to think more broadly about the way in which it works with the private sector in helping to deliver new homes.
The desire to facilitate new build appears to make some economic sense. But, the politics of delivering on new homes is considerably more difficult since the prospect of new developments naturally raises considerable local concerns. Furthermore, it does not deal with fundamental questions around the existing housing market stock. In particular, how we can further increase investment in our existing housing stock, especially given the significant land constraints that face a country like the UK. As yet, the debate around how to improve what we already have has not really taken place.

Since coming to office two years ago, Shinzo Abe’s government has been determined to revive the Japanese economy. The policy has involved ‘three arrows‘: expansionary fiscal policy, expansionary monetary policy and supply-side reforms. But figures just out show that the Japanese economy is back in recession. The economy shrank by 0.4% in quarter 3, having shrunk by 1.9% in quarter 2.
This has come as a huge disappointment for Mr Abe, who has staked his political reputation on escaping from deflation and achieving sustained economic growth. In response, he has called a general election to put a revised economic plan to the electorate.
The main cause of the reversal into recession has been an increase in the sales tax on all goods, which has dampened spending. The tax rise, planned by the previous government, was to help reduce the deficit and start tackling the huge public-sector debt, which, at over 230% of GDP, is by far the highest in the developed world. Another rise in sales tax is due in October 2015 – from 8% to 10%. Mr Abe hopes to cancel the rise and it is this that he may put to the electorate.
So what is the outlook for Japan? Will quarter 4 show economic growth, or will pessimism have set in? Will the Bank of Japan introduce even more quantitative easing, or will it wait for the latest increase in QE to take effect (see the blog post, All eased out: at least for the USA and UK)?
The following articles look at the implications of the latest news, both for Japan and globally, and at the options for the government and central bank.

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 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.
