Many UK coal mines closed in the 1970s and 80s. Coal extraction was too expensive in the UK to compete with cheap imported coal and many consumers were switching away from coal to cleaner fuels. Today many shale oil producers in the USA are finding that extraction has become unprofitable with oil prices having fallen by some 50% since mid-2014 (see A crude indicator of the economy (Part 2) and The price of oil in 2015 and beyond). So is it a bad idea to invest in fossil fuel production? Could such assets become unusable – what is known as ‘stranded assets‘?

In a speech on 3 March 2015, Confronting the challenges of tomorrow’s world, delivered at an insurance conference, Paul Fisher, Deputy Governor of the Bank of England, warned that a switch to both renewable sources of energy and actions to save energy could hit investors in fossil fuel companies.

‘One live risk right now is of insurers investing in assets that could be left ‘stranded’ by policy changes which limit the use of fossil fuels. As the world increasingly limits carbon emissions, and moves to alternative energy sources, investments in fossil fuels and related technologies – a growing financial market in recent decades – may take a huge hit. There are already a few specific examples of this having happened.

… As the world increasingly limits carbon emissions, and moves to alternative energy sources, investments in fossil fuels and related technologies – a growing financial market in recent decades – may take a huge hit. There are already a few specific examples of this having happened.’

Much of the known reserves of fossil fuels could not be used if climate change targets are to be met. And investment in the search for new reserves would be of little value unless they were very cheap to extract. But will climate change targets be met? That is hard to predict and depends on international political agreements and implementation, combined with technological developments in fields such as clean-burn technologies, carbon capture and renewable energy. The scale of these developments is uncertain. As Paul Fisher said in his speech:

‘Tomorrow’s world inevitably brings change. Some changes can be forecast, or guessed by extrapolating from what we know today. But there are, inevitably, the unknown unknowns which will help shape the future. … As an ex-forecaster I can tell you confidently that the only thing we can be certain of is that there will be changes that no one will predict.’

The following articles look at the speech and at the financial risks of fossil fuel investment. The Guardian article also provides links to some useful resources.

Yanis Varoufakis, the new Greek finance minister, is also an economist and an expert in game theory and co-author of Game Theory: a critical text. He is now putting theory into practice.

He wishes to renegotiate the terms of Greece’s debt repayments. He argues not that some of the debt should be written off, but that the terms of the repayment are far too tough.

Greece’s problem, he argues, was wrongly seen as one of a lack of liquidity and hence the Troika (of the EU, the ECB and the IMF) provided a large amount of loans to enable Greece to keep servicing its debts. These loans were conditional on Greece following austerity policies of higher taxes and reduced government expenditure. But this just compounded the problem as seen by Yanis Varoufakis. With a shrinking economy, it has been even more difficult to repay the loans granted by the Troika.

The problem, he argues, is essentially one of insolvency. The solution is to renegotiate the terms of the debt to make it possible to pay. This means reducing the size of the budget surplus that Greece is required to achieve. The Troika is currently demanding a surplus equal to 3% of GDP in 2015 and 4.5% of GDP in 2016.

The Syriza government is also seeking to link repayments to economic growth, by the issue of growth-linked bonds, whose interest rate depends on the rate of economic growth, with a zero rate if there is no growth in real GDP. He is also seeking emergency humanitarian aid

At the centre of the negotiations is a high stake game. On the one hand, Germany and other countries do not want to reduce Greece’s debts or soften their terms. The fear is that this could unleash demands from other highly indebted countries in the eurozone, such as Spain, Portugal and Ireland. Already, Podemos, Spain’s anti-austerity party is rapidly gaining support in Spain. On the other hand, the new Greek government cannot back down in its fundamental demands for easing the terms of its debt repayments.

And the threats on both sides are powerful. The Troika could demand that the original terms are met. If they are not, and Greece defaults, there could be capital flight from Greece (even more than now) and Greece could be forced from the euro. The Greeks would suffer from further falls in income, which would now be denominated in a weak drachma, high inflation and financial chaos. But that could unleash a wave of speculation against other weaker eurozone members and cause a break-up of the currency union. This could seriously harm all members and have large-scale repercussions for the global economy.

So neither side wants Greece to leave the euro. But is it a game of chicken, where if neither side backs down, ‘Grexit’ (Greek exit from the euro) will be the result? Yanis Varoufakis understands the dimensions of the ‘game’ very well. He is well aware of the quote from Keynes, ‘If you owe your bank a hundred pounds, you have a problem. But if you owe a million, it has.’ He will no doubt bring all his gaming skills to play in attempting to reach the best deal for Greece.

Questions

  1. Is a deal over the terms of repayment of Greek debt a zero sum game? Explain whether it is or not.
  2. What are Keynes Bisque bonds (or GDP-indexed bonds)? Do a Web search to find out whether they have been used and what their potential advantages and disadvantages are. Are they a good solution for both creditors and Greece in the current situation?
  3. What is meant by a ‘debt swap’? What forms can debt swaps take?
  4. Has Greece played its best cards too early?
  5. Should Greece insist on debt reduction and simply negotiate around the size and terms of that reduction?
  6. Are Greece’s new structural reform proposals likely to find favour with other EU countries and the Troika?

After Syriza’s dramatic victory in the Greek election, it is now seeking to pursue its manifesto promises of renegotiating the terms of Greece’s bailout and bringing an end to austerity policies.

The bailout of €240bn largely involved debt restructuring to give Greeks more time to pay. A ‘haircut’ (reduction) on privately held bonds, estimated to be somewhere between €50bn and €110bn, was more than offset by an increase of €130bn in loans granted by official creditors.

The terms of the bailout negotiated with the ‘Troika’ of the EU Commission, the ECB and the IMF, had forced the previous Greek government to make substantial fiscal adjustments. These have included large-scale cuts in government expenditure (including public-sector wages), increases in taxes, charges and fares, and selling state assets through an extensive programme of privatisation.

Although Greece is now regarded as having achieved a structural budget surplus (a surplus when the economy is operating at potential output: i.e. with a zero output gap), the austerity policies and a decline in inward investment have dampened the economy so much that, until last year, the actual budget deficit and public-sector debt continued to rise as tax revenues plummeted.

Since 2007, GDP has fallen by nearly 27% and the unemployment rate is around 26%. The fall in GDP has made the achievement of a reduction in the debt/GDP ratio that much harder. General government debt has risen from 103% of GDP in 2007 to 176% in 2014, and the budget deficit, although having peaked at 12.2% of GDP in 2013, has only been brought down through huge cuts.

As a report to the European Parliament from the Economic Governance Support Unit argues on page 27:

With less front-loaded fiscal adjustment, the EU-IMF financing envelope for Greece would have needed to expand, in what is already the largest financial assistance programme in percent of GDP in recent global history. On the other hand, a less rapid fiscal adjustment may have helped to preserve some of the productive capacity that, in the course of the adjustment, was destroyed.

The new government, although pledging not to default on debt, is insistent on renegotiating the debt and wants to achieve a high level of rescheduling and debt forgiveness. As the new Prime Minister, Alexis Tsipras, says:

On existing loans, we demand repayment terms that do not cause recession and do not push the people to more despair and poverty. We are not asking for new loans; we cannot keep adding debt to the mountain.

But, just as the Greek government is insistent on renegotiating its debt, so the German government and others in the EU are insisting that Greece sticks to the terms of the bailout and carries on with its current programme of debt reduction. Another haircut, they maintain, is out of the question.

We must wait to see how the negotiations play out. We are in the realms of game theory with various possible threats and promises on either side. It will be interesting to how these threats and promises are deployed.

An investigation by the International Consortium of Investigative Journalists has revealed how more than 1000 businesses from 340 major companies from around the world have used Luxembourg as a base for avoiding huge amounts of tax. Many of the companies are household names, such as Ikea, FedEx, Apple, Pepsi, Coca Cola, Dyson, Amazon, Fiat, Google, Accenture, Burberry, Procter & Gamble, Heinz, JP Morgan, Caterpillar, Deutsche Bank and Starbucks. Through complicated systems of ‘advanced tax agreements’ (ATAs), negotiated with the Luxembourg authorities via accountants PricewaterhouseCoopers (PwC), companies have used various methods of avoiding tax.

Although such measures are legal, they have denied other countries vast amounts of tax revenues on sales generated in their own countries. Instead, the much reduced tax bills have been paid to Luxembourg. The result is that this tiny country, with a population of just 550,000, has, according to the IMF, the highest (nominal) GDP per head in the world (estimated to be $116,752 in 2014).

So what methods do Luxembourg and these multinational companies use to reduce the companies’ tax bills? There are three main methods. All involve having a subsidiary based in Luxembourg: often little more than a small office with one employee, a telephone and a bank account. All involve varieties of transfer pricing: setting prices that the company charges itself in transactions between a subsidiary in Luxembourg and divisions in other countrries.

The first method is the use of internal loans. Companies lend money to themselves, say in the UK, from Luxembourg at high interest rates. The loan interest can be offset against profit in the UK, reducing tax liability to the UK tax authorities. But the interest earned by the Luxembourg subsidiary incurs very low taxes. Profits are thus effectively transferred from the UK to Luxembourg and a much lower tax bill is incurred.

The second involves royalty payments for the use of the company’s brands. These are owned by the Luxembourg subsidiary and the overseas divisions pay the Luxembourg subsidiary large sums for using the logos, designs and brand names. Thus, again, profits are transferred to Luxembourg, where there is a generous tax exemption.

The third involves generous allowances in Luxembourg for losses in the value of investments, even without the company having first to sell the investments. These losses can be offset against future profits, again reducing tax liability. By transferring losses made elsewhere to Luxembourg, again usually by some form of transfer pricing, these can be used to reduce the already small tax bill in Luxembourg even further.

Tax loopholes offered by tax havens, such as Luxembourg, the Cayman Islands and the Channel Islands, are denying exchequers around the world vast sums. Not surprisingly, countries, especially those with large deficits, are concerned to address the issue of tax avoidance by multinationals. This is one item on the agenda of the G20 meeting in Brisbane from the 12 to 16 November 2014.

The problem, however, is that, with countries seeking to attract multinational investment and to gain tax revenues from them, there is an incentive to reduce corporate tax rates. Getting any binding agreement on tax harmonisation, and creating an essentially global single market, is likely, therefore, to prove virtually impossible.

On my commute to work on the 6th October, I happened to listen to a programme on BBC radio 4, which provided some fascinating discussion on climate change, growth, capitalism and the need for co-operation. With more countries emerging as leading economic powers, pollution and emissions continue to grow. Is it time for a green revolution?

The programme considers some ‘typical’ policies and also discusses some radical solutions. There is discussion on developing and developed nations and how these countries should be looked at in terms of compensation, entitlement and aid. Carrots and sticks are analysed as means of saving the planet and how environmental damage can be reduced, without adversely affecting the growth rate of the world economy. I won’t say any more, but it’s certainly worth listening to, for an interesting discussion on one of the biggest problems that governments across the world are facing and it is not going to go away any time soon.
