Category: Essentials of Economics: Ch 10

The New Year is a time for reflection and prediction. What will the New Year bring? What does the longer-term future hold? Here are two articles from The Guardian that look into the future.

The first, by Larry Elliott, considers a number of scenarios and policy options. Although not totally doom laden, the article is not exactly cheery in its predictions. Perhaps ‘life will go on’ and the global economy will muddle through. But perhaps a new recession is around the corner or, even worse, the world is at a tipping point when things are fundamentally changing. Unless policy-makers are careful, clever and co-ordinated, perhaps a new dark age may be looming. But who knows?

Which brings us to the second article, by Gaby Hinsliff. This argues that people are pretty hopeless at predicting. “History is littered with supposed dead certs that didn’t happen – Greece leaving the euro, the premature collapse of the coalition – and wholly unimagined events that came to pass.” And economists and financial experts are little better.

Two years ago, The Observer challenged a panel of City investors to pick a portfolio of stocks and rated their performance against that of Orlando, a ginger cat who selected his portfolio by tossing a toy mouse at a sheet of paper. Inevitably, the cat triumphed.

But is this fair? If capital markets are relatively efficient, stock prices today already reflect knowable information about the future, but clearly not unknowable information.

It’s the same with economies. When information is already to hand, such as a pre-announced tax change, then its effects, ceteris paribus, can be estimated – at least roughly.

But it’s the ‘ceteris paribus‘ assumption that’s the problem. Other things are not equal. The world is constantly changing and there are all sorts of unpredictable events that will influence the outcomes of economic policy and of economic decisions more generally. And central to the problem are people’s attitudes and confidence. Mood can swing quite dramatically, from irrational exuberance to deep pessimism. And such mood changes – often triggered by some exogenous factor, such as an international dispute, an election or unexpected economic news – can rapidly gather momentum and have significant effects.

Predicting the long-term future is both easier and more difficult: easier, in that short-term cyclical effects are less relevant; more difficult in that changes that have not yet happened, such as technological changes or changes in working practices, may themselves be key determinants of the future global economy.

One of the most salutary lessons is to look at predictions made in the past about the world today and at just how wrong they have proved to be. Perhaps we need to call on Orlando more frequently.

Why ‘life will go on’ thesis about global economy might not pass muster in 2015 The Guardian, Larry Elliott (28/12/14)
Who knows what the new year holds? Certainly none of us The Guardian, Gaby Hinsliff (26/12/14)

Questions

  1. Give some examples of factors that could have a major influence on the global economy, but which are unpredictable.
  2. Is economic forecasting still worthwhile? Explain.
  3. Look at some macroeconomic forecasts made in the past about the world today. You might want to look at forecasts of agencies such as the IMF, the OECD, the World Bank and the European Commission. You can find links in the Economics Network’s Economic Data freely available online. Explain why such forecasts have differed from the actual outcome.
  4. Why, if capital markets were perfect, might Orlando be just as good as a top investment manager at predicting the future course of share prices?
  5. In what ways is economic forecasting similar to and different from weather forecasting in its methods, its use of data and its reliability?

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

  1. Explain what are meant by a Lorenz curve and a Gini coefficient? What is the relationship between the two?
  2. The Gini coefficient is one way of measuring inequality. What other methods are there? How suitable are they?
  3. 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).
  4. Distinguish between (a) progressive, (b) regressive and (c) proportional taxes?
  5. 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?
  6. Identify policy measures that would increase both equality and economic growth.
  7. Would a shift from direct to indirect taxes tend to increase or decrease inequality? Explain.
  8. 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.

This weekend, Australia will play host to the world’s leaders, as the G20 Summit takes place. The focus of the G20 Summit will be on global growth and how it can be promoted. The Eurozone remains on the brink, but Germany did avoid for recession with positive (just) growth in the third quarter of this year. However, despite Australia’s insistence on returning the remit of the G20 to its original aims, in particular promoting growth, it is expected that many other items will also take up the G20’s agenda.

In February, the G20 Finance Ministers agreed various measures to boost global growth and it is expected that many of the policies discussed this weekend will build on these proposals. The agreement contained a list of new policies that had the aim of boosting economy growth of the economies by an extra 2% over a five year period. If this were to happen, the impact would be around £1.27 trillion. The agreed policies will be set out in more detail as part of the Brisbane Action Plan.

As well as a discussion of measures to promote global growth as a means of boosting jobs across the world, there will also be a focus on using these measures to prevent deflation from becoming a problem across Europe. Global tax avoidance by some of the major multinationals will also be discussed and leaders will be asked to agree on various measures. These include a common reporting standard; forcing multinationals to report their accounts country by country and principles about disclosing the beneficial ownership of companies. It it also expected that the tensions between Russia and Ukraine will draw attention from the world leaders. But, the main focus will be the economy. Australia’s Prime Minister, Tony Abbott said:

“Six years ago, the impacts of the global financial crisis reverberated throughout the world. While those crisis years are behind us, we still struggle with its legacy of debt and joblessness…The challenge for G20 leaders is clear – to lift growth, boost jobs and strengthen financial resilience. We need to encourage demand to ward off the deflation that threatens the major economies of Europe.”

Many people have protested about the lack of action on climate change, but perhaps this has been addressed to some extent by the deal between China and the USA on climate change and Barak Obama’s pledge to make a substantial contribution to the Green Climate Fund. This has caused some problems and perhaps embarrassment for the host nation, as Australia has remained adamant that despite the importance of climate change, this will not be on the agenda of the G20 Summit. Suggestions now, however, put climate change as the final communique.

Some people and organisations have criticised the G20 and questioned its relevance, so as well as discussing a variety of key issues, the agenda will more broadly be aiming to address this criticism. And of course, focus will also be on tensions between some of the key G20 leaders. The following articles consider the G20 Summit.

The spectre of debt has awoken many of us in the night. Indebtedness is a key economic issue in the 2010s. Economists are devoting ever increasing amounts of research time trying to understand its impact on economic behaviour. This will not surprise you when you learn that the debt owed by the UK non-bank private sector to banks stood at £2.17 trillion at the end of September. This is the equivalent to 150% of annual GDP.

Chart 1 shows the stock of outstanding lending by Monetary Financial Institutions (banks and building societies) to the non-bank private sector bank since 1979. Back then the non-bank private sector had bank debt to the tune of around £70 billion or 10 per cent of GDP. Today’s figure is nearly 3000 per cent higher! Of this debt, around about 55 per cent is currently held by the household sector, 27 per cent by Other Financial Corporations (such as insurance companies and pension funds) and 18 per cent by private non-financial corporations. (Click here for a PowerPoint of the chart.)

Chart 2 shows the stocks of debt as percentages of annual GDP. We can infer from it that there are waves of growth in bank debt. Two notable periods are during the 1980s and again from the late 1990s up to the financial crisis of the late 2000s. During the early and mid 1990s the relative size of debt stocks tended to stabilise while in the early 2010s the actual stocks of debt, as well as relative to GDP, declined. A credit binge seems to be followed by a period of consolidation. (Click here for a PowerPoint of the chart.)

It is important that we understand the drivers of the growth of debt. The impact of debt on the balance sheets of the non-bank private sector and on banks themselves has implications for economic behaviour. In the early 2010s this has been to markedly slow the pace of growth through its impact on aggregate demand. Economic agents have, in general, looked to consolidate. There is no doubt that this partly reflects a precautionary motive. An important means by which debt and the balance sheets on which it is recorded affect behaviour is through a precautionary mechanism. This is difficult to accurately quantify because it represents a psychological influence on spending. Furthermore, it is affected by the prevailing circumstances of the time.

In looking to understand the factors that affect the growth of debt we may, as a result, learn more about the framework within which we may want banks and their customers to operate. Consequently, we may be in a better position to ensure sustainable longer-term growth and development. If there are cycles in credit it is important that we understand why they arise and whether, as some have suggested, they are an inherent part of the financialised economy in which we live. If they are, can we mitigate their potentially destabilising effects?
