The latest edition of the IMF’s Fiscal Monitor, ‘Tackling Inequality’ challenges conventional wisdom that policies to reduce inequality will also reduce economic growth.
While some inequality is inevitable in a market-based economic system, excessive inequality can erode social cohesion, lead to political polarization, and ultimately lower economic growth.
The IMF looks at three possible policy alternatives to reduce inequality without damaging economic growth
The first is a rise in personal income tax rates for top earners. Since top rates have been cut in most countries, with the OECD average falling from 62% to 35% over the past 30 years, the IMF maintains that there is considerable scope of raising top rates, with the optimum being around 44%. Evidence suggests that income tax elasticity is low at most countries’ current top rates, meaning that a rise in top income tax rates would only have a small disincentive effect on earnings.
An increased progressiveness of income tax should be backed by sufficient taxes on capital to prevent income being reclassified as capital. Different types of wealth tax, such as inheritance tax, could also be considered. Countries should also reduce the opportunities for tax evasion.
The second policy alternative is a universal basic income for all people. This could be achieved by various means, such as tax credits, child benefits and other cash benefits, or minimum wages plus benefits for the unemployed or non-employed.
The third is better access to health and education, both for their direct effect on reducing inequality and for improving productivity and hence people’s earning potential.
In all three cases, fiscal policy can help through a combination of taxes, benefits and public expenditure on social infrastructure and human capital.
But a major problem with using increased tax rates is international competition, especially with corporation tax rates. Countries are keen to attract international investment by having corporation tax rates lower than their rivals. But, of course, countries cannot all have a lower rate than each other. The attempt to do so simply leads to a general lowering of corporation tax rates (see chart in The Economist article) – to a race to the bottom. The Nash equilibrium rate of such a game is zero!

Questions
- Referring to the October 2017 Fiscal Monitor, linked above, what arguments does the IMF use for suggesting that the optimal top rate of income tax is considerably higher than the current OECD average?
- What are the arguments for introducing a universal basic income? Should this depend on people’s circumstances, such as the number of their children, assets, such as savings or property, and housing costs?
- Find out the details of the UK government’s Universal Credit. Does this classify as a universal basic income?
- Why may governments reject the IMF’s policy recommendations to tackle inequality?
- In what sense can better access to health and education be seen as a means of reducing inequality? How is inequality being defined in this case?
- Find out what the UK Labour Party’s policy is on rates of income tax for top earners. Is this consistent with the IMF’s policy recommendations?
- What does the IMF report suggest about the shape of the Laffer curve?
- Explain what is meant by tax elasticity and how it relates to the Laffer curve?
According to a new report, Time for Change published by the Institute for Public Policy Research (IPPR), ‘The British economic model needs fundamental reform.’
It is no longer generating rising earnings for a majority of the population, and young people today are set to be poorer than their parents. Beneath its headlines figures, the economy is suffering from deep and longstanding weaknesses, which make it unfit to face the challenges of the 2020s.
The report by the IPPR’s Commission on Economic Justice is an interim one, with the final report due in the latter part of next year. The commission was set up in 2016 and includes business leaders, such as the heads of John Lewis and Siemens, the TUC General Secretary, the Archbishop of Canterbury and other leading figures.
Commenting on the interim report, Justin Welby, the Archbishop of Canterbury said
Our economic model is broken. Britain stands at a watershed moment where we need to make fundamental choices about the sort of economy we need. We are failing those who will grow up into a world where the gap between the richest and poorest parts of the country is significant and destabilising
The report found that wages have stagnated for the majority of the population since the financial crisis of 2007/8. Wage income has fallen as a proportion of national income, while the proportions going to income from profits and property have risen. Young people are poorer than previous generations of young people.
Despite low unemployment, many people are on zero-hour contracts, part-time contracts or employed on a casual basis. For many, their jobs are insecure and they have no bargaining power.
The UK for many years has had a lower rate of investment that other developed economies and productivity, in terms of output per hour, is the lowest of its major competitors. Productivity in Germany is 36% higher than in the UK; in France and the USA it is 29% higher. Although there are some internationally competitive UK firms with high productivity, the country has:
a longer ‘tail’ of low-productivity businesses, in which weak management and poor use of skills leads to ‘bad jobs’ and low wages.
There are many other challenges, including an ageing population, uncertainties from Brexit, a large current account deficit, increased competition from abroad and growth once more in private-sector debt, which means that consumption may cease to be the main driver of economic growth as people seek to curb their borrowing.
The report is also critical of fiscal policy, which with record low interest rates could have been used to finance infrastructure projects as well as supporting public services.
The report recommends three approaches:
The first is institutional reform to support investment.
The second is making the economy more competitive through a coherent industrial strategy, reform of the financial sector to support long-term investment, reform of corporate governance to promote business success and tackling the market dominance of companies such as Amazon and Google.
The third is to bring greater social justice and equality through encouraging more secure and better-paid jobs, strengthening trades unions and reforming the tax system to make it fairer and smarter.
Not surprisingly the government has defended its record of reducing debt, presiding over falling unemployment and reduced inequality as measured by a reduced Gini coefficient. However, there has only been a modest fall in the Gini coefficient, from 0.333 in 2009/10 to 0.315 in 2016/7, and this has largely been the result of the very rich seeing a decline in income from assets.

In the last blog post, As UK inflation rises, so real wages begin to fall, we showed how the rise in inflation following the Brexit vote is causing real wages in the UK to fall once more, after a few months of modest rises, which were largely due to very low price inflation. But how does this compare with other OECD countries?
In an article by Rui Costa and Stephen Machin from the LSE, the authors show how, from the start of the financial crisis in 2007 to 2015 (the latest year for which figures are available), real hourly wages fell further in the UK than in all the other 27 OECD countries, except Greece (see the chart below, which is Figure 5 from their article). 
Indeed, only in Greece, the UK and Portugal were real wages lower in 2015 than in 2007.
The authors examine a number of aspects of real wages in the UK, including the rise in self employment, differences by age and sex, and for different percentiles in the income distribution. They also look at how family incomes have suffered less than real wages, thanks to the tax and benefit system.
The authors also look at what the different political parties have been saying about the issues during their election campaigns and what they plan to do to address the problem of falling, or only slowly rising, real wages.

The UK Chancellor of the Exchequer, Philip Hammond, announced in the Budget this week that national insurance contributions (NICs) for self-employed people will rise from 9% to 11% by 2019. These are known as ‘Class 4’ NICs. The average self-employed person will pay around £240 more per year, but those on incomes over £45,000 will pay £777 more per year. Many of the people affected will be those working in the so-called ‘gig economy’. This sector has been growing rapidly in recent years and now has over 4 million people working in it.
Workers in the gig economy are self employed, but are often contracted to an employer. They are paid by the job (or ‘gig’: like musicians), rather than being paid a wage. Much of the work is temporary, although many in the gig economy, such as taxi drivers and delivery people stick with the same job. The gig economy is just one manifestation of the growing flexibility of labour markets, which have also seen a rise in temporary employment, part-time employment and zero-hour contracts.
Working in the gig economy provides a number of benefits for workers. Workers have greater flexibility in their choice of hours and many work wholly or partly from home. Many do several ‘gigs’ simultaneously, which gives variety and interest.
In terms of economic theory, this flexibility gives workers a greater opportunity to work the optimal amount of time. This optimum involves working up to the point where the marginal benefit from work, in terms of pay and enjoyment, equals the marginal cost, in terms of effort and sacrificed leisure.
For firms using people from the gig economy, it has a number of advantages. They are generally cheaper to employ, as they do not need to be paid sick pay, holiday pay or redundancy; they are not entitled to parental leave; there are no employers’ national insurance contributions to pay (which are at a rate of 13.8% for employers); the minimum wage does not apply to such workers as they are not paid a ‘wage’. Also the firm using such workers has greater flexibility in determining how much work individuals should do: it chooses the amount of service it buys in a similar way that consumers decide how much to buy.
Many of these advantages to firms are disadvantages to the workers in the gig economy. Many have little bargaining power, whereas many firms using their services do. It is not surprising then that the Chancellor’s announcement of a 2 percentage point rise in NICs for such people has met with such dismay by the people affected. They will still pay less than employed people, but they claim that this is now not enough to compensate for the lack of benefits they receive from the state or from the firms paying for their services.
Some of the workers in the gig economy can be seen as budding entrepreneurs. If you have a specialist skill, you may use working in the gig economy as the route to setting up your own business and employing other people. A self-employed plumber may set up a plumbing company; a management consultant may set up a management consultancy agency. Another criticism of the rise in Class 4 NICs is that this will discourage such budding entrepreneurs and have longer-term adverse supply-side effects on the economy.
As far as the government is concerned, there is a worry about people moving from employment to self-employment as it tends to reduce tax revenues. Not only will considerably less NIC be paid by previous employers, but the scope for tax evasion is greater in self-employment. There is thus a trade-off between the extra output and small-scale investment that self-employment might bring and the lower NIC/tax revenue for the government.

Economists were generally in favour of the UK remaining in the EU and highly critical of the policy proposals of Donald Trump. And yet the UK voted to leave the EU and Donald Trump was elected.
People rejected the advice of most economists. Many blamed the failure of most economists to predict the 2007/8 financial crisis and to find solutions to the growing gulf between rich and poor, with the majority stuck on low incomes.
So to what extent are economists to blame for the rise in populism – a wave that could lead to electoral upsets in various European countries? The podcast below brings together economists and politicians from across the political spectrum. It is over an hour long and provides an in-depth discussion of many of the issues and the extent to which economists can provide answers.

An increased progressiveness of income tax should be backed by sufficient taxes on capital to prevent income being reclassified as capital. Different types of wealth tax, such as inheritance tax, could also be considered. Countries should also reduce the opportunities for tax evasion.
