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

  1. 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?
  2. 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?
  3. Find out the details of the UK government’s Universal Credit. Does this classify as a universal basic income?
  4. Why may governments reject the IMF’s policy recommendations to tackle inequality?
  5. 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?
  6. 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?
  7. What does the IMF report suggest about the shape of the Laffer curve?
  8. Explain what is meant by tax elasticity and how it relates to the Laffer curve?

We have reported frequently in our blogs about concerns over rising debt levels among UK households. We previously noted the concerns expressed in July 2014 by the Prudential Regulation Authority (PRA) that the growth in consumer credit (unsecured lending) was stretching the financial well-being of individuals with implications for the resilience of lenders’ credit portfolios. Now the Chief Executive of the Financial Conduct Authority (FCA), Andrew Bailey, in an interview to the BBC has identified the growing problem of debt among young people.

In his interview Mr Bailey stresses that the growth in debt amongst younger people is not ‘reckless borrowing’ and so not borne out of a lack of willpower or ‘present bias’ (see John’s blog Nudging mainstream economists). Rather, it is borrowing simply to meet basic living costs.

In his interview Mr Bailey goes on to identify generational shifts in patterns of wealth and debt. He notes:

There are particular concentrations [of debt] in society, and those concentrations are particularly exposed to some of the forms and practices of high cost debt which we are currently looking at very closely because there are things in there that we don’t like.

There has been a clear shift in the generational pattern of wealth and income, and that translates into a greater indebtedness at a younger age. That reflects lower levels of real income, lower levels of asset ownership. There are quite different generational experiences.

Mr Bailey goes on to echo concerns expressed back in July by the Prudential Regulation Authority in relation to the growth in consumer credit. The chart illustrates the scale of the accumulation of consumer credit (unsecured lending) across all individuals in the UK. In August 2017 the stock of unsecured debt rose to £203 billion, the highest level since December 2008 when the financial crisis was unfolding. (Click here to download a PowerPoint of the chart).

In concluding his BBC interview, Mr Bailey notes that credit should be available to younger people. Credit helps individuals to ‘smooth income’ and that this is something which is increasingly important with more people having erratic incomes as the gig-economy continues to grow. However, he notes that credit provision needs to be “sustainable”.

In various blogs, we’ve looked at the UK’s low productivity growth, both relative to other countries and relative to the pre-1998 financial crisis (see, for example, The UK productivity puzzle and Productivity should we be optimistic?). Productivity is what drives long-term economic growth as it determines potential GDP. If long-term growth is seen as desirable, then a fall in productivity represents a serious economic problem.

Recent data suggest that the problem, if anything, is worse than previously thought and does not seem to be getting better. Productivity is now some 21% below what it would have been had productivity growth continued at the rate experienced in the years before the financial crisis (see second chart below).

In its latest productivity statistics, the ONS reports that labour productivity (in terms of output per hour worked) fell by 0.1% in the second quarter of 2017. This follows a fall of 0.5% in quarter 1. Over the whole year to 2017 Q2, productivity fell by 0.3%.

Most other major developed countries have much higher productivity than the UK. In 2016, Italy’s productivity was 9.9% higher than the UK’s; the USA’s was 27.9%, France’s was 28.7% and Germany’s was 34.5% higher. What is more, their productivity has grown faster (see chart).

But what of the future? The Office for Budget responsibility publishes forecasts for productivity growth, but has consistently overestimated it. After predicting several times in the past that UK productivity growth would rise towards its pre-financial crisis trend of around 2% per year, in its October 2017 Forecast evaluation Report it recognises that this was too optimisitic and revises downwards its forecasts for productivity growth for 2017 and beyond.

As the period of historically weak productivity growth lengthens, it seems less plausible to assume that potential and actual productivity growth will recover over the medium term to the extent assumed in our most recent forecasts. Over the past five years, growth in output per hour has averaged 0.2 per cent. This looks set to be a better guide to productivity growth in 2017 than our March forecast of 1.6 per cent.

Looking further ahead, it no longer seems central to assume that productivity growth will recover to the 1.8 per cent we assumed in March 2017 within five years.

But why has productivity growth not returned to pre-crisis levels? There are five possible explanations.

The first is that there has been labour hoarding. But with companies hiring more workers, this is unlikely still to be true for most employers.

The second is that very low interest rates have allowed some low-productivity companies to survive, which might otherwise have been driven out of business.

The third is a reluctance of banks to lend for investment. After the financial crisis this was driven by the need for them to repair their balance sheets. Today, it may simply be greater risk aversion than before the financial crisis, especially with the uncertainties surrounding Brexit.

The fourth is a fall in firms’ desire to invest. Although investment has recovered somewhat from the years directly following the financial crisis, it is still lower than might be expected in an economy that is no longer is recession. Indeed, there has been a much slower investment recovery than occurred after previous recessions.

The fifth is greater flexibility in the labour market, which has subdued wages and has allowed firms to respond to higher demand by taking on more relatively low-productivity workers rather than having to invest in human capital or technology.

Whatever the explanation, the solution is for more investment in both technology and in physical and human capital, whether by the private or the public sector. The question is how to stimulate such investment.

An economy that becomes dependent on credit can, in turn, become acutely volatile. Too much credit and there exists the potential for financial distress which can result in an economic slowdown as people cut back on spending. Too little credit and the growth in aggregate demand is subdued. Some argue that this is what now faces a financialised economy like the UK. Even it this overstates the significance of credit, there is no doubt that UK credit data is keenly followed by economists and policymakers.

Recent rates of credit accumulation by individuals have raised concern. In July 2014 the Prudential Regulation Authority (PRA) of the Bank of England issued a statement voicing its concern that the growth in consumer credit, also known as unsecured lending, was stretching the financial well-being of individuals and that the resilience of lenders’ consumer credit portfolios was therefore reducing.

Chart 1 illustrates the scale of the flows of both consumer credit (unsecured lending) and mortgages (secured credit) from banks and building societies to individuals. It shows the amount of credit net of repayments lent over the last 12 months. In the 12 months to July 2017 the net accumulation of consumer credit was £18.2 billion while that of secured borrowing was £40.8 billion. Although the 12-month level of consumer credit accumulation was down from its recent peak of £19.2 billion in November 2016, total net lending (including secured lending) to individuals of £59.0 billion was its highest since September 2008. (Click here to download a PowerPoint of the chart).

To help put in context the size of flows of net lending Chart 2 shows the annual flows of consumer credit and secured debt as percentages of GDP. In this case each observation measures net lending over the past four quarters as a percentage of annual GDP. The latest observation is for 2017 Q2 and shows that the annual net flow of consumer credit was equivalent to 0.94 per cent of GDP while that for secured borrowing was 1.78 per cent of GDP. While the flows of consumer credit and secured borrowing as shares of national income have eased a little from their values in the second half of last year, they have not eased significantly. (Click here to download a PowerPoint of the chart).

Despite the recent strength of borrowing, levels are nothing like those seen in the mid 2000s. Nonetheless, we need to see the current accumulation of debt in the context of two important factors: debt already accumulated and the future macroeconomic environment. Chart 3 gives some insight to the first of these two by looking at stocks of debt outstanding as shares of GDP. The total debt-to-GDP ratio peaked 90 percent in 2009 before relatively slower growth in credit accumulation saw the ratio fall back. The ratio has now been at or around the 78 per cent level consistently for the past two or so years. (Click here to download a PowerPoint of the chart).

The ratio of the stock of consumer debt to GDP peaked in 2008 at 13.3 per cent. It too fell back reaching 9.05 per cent in the middle of 2014. Since that time the ratio has been rising and by the end of the second quarter of this year was 10.1 per cent. The PRA appears not only to be concerned by this but also the likely unwinding of what it describes as the ‘current benign macroeconomic environment and historically low arrears rates’.

Going forward, we might expect to see ever closer scrutiny not only of the aggregate indicators referred to here but of an array of credit indicators. The PRA statement, for example, refers to the number of , ‘0% interest credit card offers’, falling interest rates on unsecured personal loans and the growth of motor finance loans. The hope is that we can avoid the costs of financial distress that so starkly affected the economy in the late 2000s and that continue to cast a shadow over today’s economic prospects.

Ten years ago (on 9 August 2007), the French bank BNP Paribas sparked international concern when it admitted that it didn’t know what many of its investments in the US sub-prime property market were worth and froze three of its hedge funds. This kicked off the financial crisis and the beginning of the credit crunch.

In September 2007 there was a run on the Northern Rock bank in the UK, forcing the Bank of England to provide emergency funding. Northern Rock was eventually nationalised in February 2008. In July 2008, the US financial authorities had to provide emergency assistance to America’s two largest mortgage lenders, Fannie Mae and Freddie Mac.

Then in September 2008, the financial crisis really took hold. The US bank, Lehman Brothers, filed for bankruptcy, sending shock waves around the global economy. In the UK, Lloyds TSB announced that it was taking over the UK’s largest mortgage lender, Halifax Bank Of Scotland (HBOS), after a run on HBOS shares.

Later in the month, Fortis, the huge Belgian banking, finance and insurance company, was partly nationalised to prevent its bankruptcy. Also the UK government was forced to take control of mortgage-lender, Bradford & Bingley’s, mortgages and loans, with the rest of the business sold to Santander.

Early in October 2008, trading was suspended in the main Icelandic banks. Later in the month, the UK government announced a £37 billion rescue package for Royal Bank of Scotland (RBS), Lloyds TSB and HBOS. Then in November it partially nationalised RBS by taking a 58% share in the bank. Meanwhile various other rescue packages and emergency loans to the banking sector were taking place in other parts of the world. See here for a timeline of the financial crisis.

So, ten years on from the start of the crisis, have the lessons of the crisis been learnt. Could a similar crisis occur again?

The following articles look at this question and the answers are mixed.

On the positive side, banks are much more highly capitalised than they were ten years ago. Moves by the Basel Committee on Banking Supervision in its Basel III regulatory framework have ensured that banks are much more highly capitalised and operate with higher levels of liquidity. What is more, banks are generally more cautious about investing in highly complex and risky collateralised assets.

On the negative side, increased flexibility in labour markets, although helping to keep unemployment down, has allowed a huge squeeze on real wages as austerity measures have dampened the economy. What is more, household debt is rising to possibly unsustainable levels. Over the past year, unsecured debt (e.g. personal loans and credit card debt) have risen by 10% and yet (nominal) household incomes have risen by only 1.5%. While record low interest rates make such loans relatively affordable, when interest rates do eventually start to rise, this could put a huge strain on household finances. But if households start to rein in their borrowing, this would put downward pressure on aggregate demand and jeopardise economic growth.
