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
- Is a deal over the terms of repayment of Greek debt a zero sum game? Explain whether it is or not.
- 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?
- What is meant by a ‘debt swap’? What forms can debt swaps take?
- Has Greece played its best cards too early?

- Are Greece’s new structural reform proposals likely to find favour with other EU countries and the Troika?
According to a report by the McKinsey Global Institute, global debt is now higher than before the financial crisis. And that crisis was largely caused by excessive lending. As The Telegraph article linked below states:
The figures are as remarkable as they are terrifying. Global debt – defined as the liabilities of governments, firms and households – has jumped by $57 trillion, or 17% of global GDP, since the fourth quarter of 2007, which was supposed to be the peak of the bad old credit-fuelled days. In 2000, total debt was worth 246% of global GDP; by 2007, this had risen to 269% of GDP and today we are at 286% of GDP.
This is not how policy since the financial crisis was supposed to have worked out. Central banks and governments have been trying to encourage greater saving and reduced credit as a percentage of 
GDP, a greater capital base for banks, and reduced government deficits as a means of reducing government debt. But of 47 large economies in the McKinsey study, only five have succeeded in reducing their debt/GDP ratios since 2007 and in many the ratio has got a lot higher. China, for example, has seen its debt to GDP ratio almost double – from 158% to 282%, although its government debt remains low relative to other major economies.
Part of the problem is that the lack of growth in many countries has made it hard for countries to reduce their public-sector deficits to levels that will allow the public-sector debt/GDP ratio to fall.
In terms of the UK, private-sector debt has been falling as a percentage of GDP. But this has been more than offset by a rise in the public-sector debt/GDP ratio. As Robert Peston says:
[UK indebtedness] increased by 30 percentage points, to 252% of GDP (excluding financial sector or City debts) – as government debts have jumped by 50 percentage points of GDP, while corporate and household debts have decreased by 12 and 8 percentage points of GDP respectively.
So what are the likely consequences of this growth in debt and what can be done about it? The articles and report consider these questions.

Newspaper headlines this week read that the UK’s balance of trade deficit has widened to £34.8bn, the largest since 2010. And when you exclude services, the trade in goods deficit, at £119.9bn is the largest ever in nominal terms and is also likely to be the largest as a percentage of GDP.
So far so bad. But when you look a little closer, the picture is more mixed. The balance of trade deficit (i.e. on both goods and services) narrowed each quarter of 2014, although the monthly figure did widen in December 2014. In fact the trade in goods deficit increased substantially in December from £9.3bn to £10.2bn.
At first sight the widening of the trade deficit in December might seem surprising, given the dramatic drop in oil prices. Surely, with demand for oil being relatively inelastic, a large cut in oil prices should significantly reduce the expenditure on oil? In fact the reverse happened. The oil deficit in December increased from £598m to £940m. The reason is that oil importing companies have been stockpiling oil while low prices persist. Clearly, this is in anticipation that oil prices will rise again before too long. What we have seen, therefore, is a demand that is elastic in the short run, even though it is relatively inelastic in the medium run.
But the trade deficit is still large. Even when you strip out oil, the deficit in December still rose – from £8.7bn to £9.2bn. There are two main reasons for this deterioration.
The first is a strong pound. The sterling exchange rate index rose by 1.8% in December and a further 0.4% in January. With quantitative easing pushing down the value of the euro and loose monetary policies in China and Australia pushing down the value of their currencies, sterling is set to appreciate further.
The second is continuing weakness in the eurozone and a slowing of growth in some major developing countries, including China. This will continue to dampen the growth in UK exports.
But what of the overall current account? Figures are at present available only up to 2014 Q3, but the picture is bleak (see the chart). As the ONS states:
The current account deficit widened in Q3 2014, to 6.0% of nominal Gross Domestic Product GDP, representing the joint largest deficit since Office for National Statistics (ONS) records began in 1955.
This deterioration in performance can be partly attributed to the recent weakness in the primary income balance [see]. This also reached a record deficit in Q3 2014 of 2.8% of nominal GDP; a figure that can be primarily attributed to a fall in UK residents’ earnings from investment abroad, and broadly stable foreign resident earnings on their investments in the UK
The primary income account captures income flows into and out of the UK economy, as opposed to current transfers (secondary income) from taxes, grants, etc. The large deficit reflects a decline in the holding by UK residents of foreign assets from 92% of GDP in 2008 to 67% by the end of 2014. This, in turn, reflects the poorer rate of return on many of these assets. By contrast, the holdings of UK assets by foreign residents has increased. They have been earning a higher rate of return on these assets than UK residents have on foreign assets. And so, despite UK interest rates having fallen, as the quote above says, foreign residents’ earnings on their holding of UK assets has remained broadly stable.

The first link below is to an excellent article by Noriel Roubini, Professor of Economics at New York University’s Stern School of Business. Roubini was one of the few economists to predict the 2008 financial crisis and subsequent recession. In this article he looks at the current problem of substantial deficiency of demand: in other words, where actual output is well below potential output (a negative output gap). It is no wonder, he argues, that in these circumstances central banks around the world are using unconventional monetary policies, such as virtually zero interest rates and quantitative easing (QE).
He analyses the causes of deficiency of demand, citing banks having to repair their balance sheets, governments seeking to reduce their deficits, attempts by firms to cut costs, effects of previous investment in commodity production and rising inequality.
The second link is to an article about the prediction by the eminent fund manager, Crispin Odey, that central banks are running out of options and that the problem of over-supply will lead to a global slump and a stock market crash that will be ‘remembered in a hundred years’. Odey, like Roubini, successfully predicted the 2008 financial crisis. Today he argues that the looming ‘down cycle will cause a great deal of damage, precisely because it will happen despite the efforts of central banks to thwart it.’
I’m sorry to post this pessimistic blog and you can find other forecasters who argue that QE by the ECB will be just what is needed to stimulate economic growth in the eurozone and allow it to follow the USA and the UK into recovery. That’s the trouble with economic forecasting. Forecasts can vary enormously depending on assumptions about variables, such as future policy measures, consumer and business confidence, and political events that themselves are extremely hard to predict.
Will central banks continue to deploy QE if the global economy does falter? Will governments heed the advice of the IMF and others to ease up on deficit reduction and engage in a substantial programme of infrastructure investment? Who knows?

Questions
- Explain each of the types of unconventional monetary policy identified by Roubini.
- How has a policy of deleveraging by banks affected the impact of quantitative easing on aggregate demand?
- Assume you predict that global economic growth will increase over the next two years. What reasons might you give for your prediction?
- Why have most commodity prices fallen in recent months? (In the second half of 2014, the IMF all-commodity price index fell by 28%.)
- What is likely to be the impact of falling commodity prices on global demand?
- Some neo-liberal economists had predicted that central bank policies ‘would lead to hyperinflation, the US dollar’s collapse, sky-high gold prices, and the eventual demise of fiat currencies at the hands of digital krypto-currency counterparts’. Why, according to Roubini, did the ‘root of their error lie in their confusion of cause and effect’?
One effect of an expansionary monetary policy is a depreciation of the exchange rate. Take the case of countries using a combination of a reduction in central bank interest rates and quantitative easing (QE). A fall in interest rates will encourage an outflow of finance; and part of the money created through quantitative easing will be used to purchase foreign assets. Both create an increased demand for foreign currencies and drive down the exchange rate.
The latest case of expansionary monetary policy is that employed by the ECB. After months of promising to ‘do whatever it takes’ and taking various steps towards full QE, the ECB finally announced a large-scale QE programme on 22 January 2015.
With people increasingly predicting QE and with the ECB reducing interest rates, so the euro depreciated. Between March 2014 and 21 January 2015, the euro depreciated by 20.2% against the dollar and the euro exchange rate index depreciated by 9.7%. With the announced programme of QE being somewhat larger than markets expected, in the week following the announcement the euro fell a further 2.3% against the dollar, and the euro exchange rate index also fell by 2.3%. The euro is now at its lowest level against the US dollar since April 2003 (see chart).
The depreciation of the euro will be welcome news for eurozone exporters. It makes their exports cheaper in foreign currency terms and thus makes their exports more competitive. 
Similarly Japanese exporters were helped by the depreciation of the yen following the announcement on 31 October 2014 by the Bank of Japan of an increase in its own QE programme. The yen has depreciated by 7.7% against the dollar since then.
But every currency cannot depreciate against other currencies simultaneously. With any bilateral exchange rate, the depreciation of one currency represents an appreciation of the other. So just as the euro and yen have depreciated against the dollar, the dollar has appreciated against the euro and yen. This has made US goods less competitive relative to eurozone and Japanese goods.
The danger is that currency wars will result, with monetary policy being used in various countries to achieve competitive depreciations. Already, the Swiss have been forced, on 15 January, to remove the cap with the euro at SF1 – €0.833. Since then the Swiss franc has appreciated by some 15% to around SF1 – €0.96. Will the Swiss now be forced to relax their monetary policy?
The Danish and Canadian central banks have cut their interest rates, hoping to stem an appreciation of their currencies. On 28 January, the Monetary Authority of Singapore sold Singapore dollars to engineer a depreciation. The Singapore dollar duly fell by the most in over four years.
But are these policies simply beggar-my-neighbour policies? Is it a zero-sum game, where the gains to the countries with depreciating currencies are exactly offset by losses to the those with appreciating ones? Or is there a net gain from overall looser monetary policy at a time of sluggish growth? Or is there a net loss from greater currency volatility, which will create greater uncertainty and dampen cross-border investment? The following article explore the issues.
