The negotiations between Greece and the ‘troika’ of creditors (the IMF, the European Commission and the ECB) have seen many twists and turns before breaking down on 26 June. Throughout, both sides have sought to give as little as possible while seeking a compromise. Both sides have claimed that their position is reasonable, even though a gulf has remained between them.
What has been playing out is a high-stakes game, where the optimum outcome for each side is quite different.
Greece seeks bailout terms that would allow it to achieve a smaller primary budget surplus (but still a surplus in the midst of a deep recession). The surplus would be achieved largely through tax rises on the wealthy rather than further cuts that would hit the poor hard. It is also seeking a substantial amount of debt forgiveness to make servicing the remaining debt possible.
The troika is seeking a larger budget surplus than the Greeks are willing to contemplate. This, it maintains, should be achieved largely through additional cuts in government expenditure, including further reductions in pensions and in public-sector wages.
Both sides used threats and promises as the negotiations became more and more acrimonious.
The troika threatened to withhold the final €7.2bn of the bailout necessary to pay the €1.6bn due to the IMF on 30 June, unless the Greeks accepted the terms of the austerity package put to them. The Greek Prime Minister, Alexis Tsipras, in rejecting the proposals, called a referendum on the package. This threatens the stability of the eurozone as a No vote, if it led to a Greek exit from the eurozone, could undermine confidence in monetary union. After all, if Greece could be forced out, other countries facing severe difficulties might also be forced out at some point in the future. Once a country leaves the eurozone, the monetary union becomes more like a system of pegged exchange rates. And pegged exchange rates are open to destabilising speculation at times of economic divergence.
A Greek exit from the euro (dubbed ‘Grexit’) is seen as undesirable by most Greeks and by most politicians in the rest of Europe. The optimum for both sides collectively would be a compromise, which saw more modest cuts by Greece and the eurozone remaining intact. By both sides seeking to maximise their own position, the Nash equilibrium is certainly not the best outcome.
But as long as the troika believes that the Greeks are likely to vote Yes to the proposed bailout terms, it still hopes to get the outcome that is best from its point of view – an outcome that would probably involve regime change. And as long as the Greek government hopes that a No vote will force the troika to think again and come back with less austere proposals, it still hopes to get the outcome that is best from its point of view. But the outcome of this game of ‘chicken’ could well be Grexit and a Nash equilibrium that neither side wants.
But while the endgame is being played out by politicians, people in Greece are suffering. Policies of severely depressing aggregate demand to turn a large budget deficit into a primary budget surplus have led to the economy shrinking by 26%, overall unemployment of 27% and youth unemployment of over 60%. The Greeks truly believe themselves to be stuck between a rock and a hard place.
The following articles look at the nature of the ‘game’ being played and at the effects on the Greek economy, both of the proposed austerity package proposed by the troika and Grexit. They also look at the knock-on effects for the eurozone, the EU and the global economy.

Deloitte recently published its 24th Annual Review of Football Finance and it contained some surprising results. Historically, most teams in the English Premier League (EPL) have made accounting losses with any increases in revenues being offset by higher wage costs. However, this report found that in 2013–14 most teams in the EPL actually made accounting profits.
The Deloitte’s review reported that the combined operating profits of clubs in the EPL increased from £82 million in 2012–13 to £614 million on 2013–14 – an enormous increase of 649%. Nearly all of the teams (19 out of 20) in the league made an operating profit while 14 also reported pre-tax profits. Dan Jones, head of Deloitte’s Sports Business Group, commented that:
“The change in club profitability in 2013–14 was more profound than anything we could have forecast.”
Why has the profitability of teams in the EPL suddenly improved so dramatically? One important factor was the significant increase in revenue. The combined income of the teams was £3.26 billion in 2013–14 – an increase of £735 million, or 29% on the previous year. Although match-day and commercial revenue both increased, the majority of this growth in income (nearly 80%) came from the sale of broadcast rights. The 2013–14 season was the first year of a new three-year contract that raised over £1.7 billion per year from the sale of these rights in both the UK and overseas.
However, clubs in the EPL have received big increases in revenue from TV deals before and still made substantial accounting losses. For example, the broadcasting contract that ran from 2010–13 generated over £1.1 billion per season – a £243 million per annum increase on the previous deal. Significantly, in the first year of this deal (2010–11), 81% of this increase in revenue went straight into higher player salaries, whereas in 2013–14 this figure was only 16%. The ratio of wages to turnover also fell from 71% in 2012–13 to 58% in 2013–14
So why did a smaller proportion of the increase in revenue go to the players compared with previous years? The explanation appears to be the impact of two new controls and regulations that were implemented by the EPL at the beginning of the 2013–14 season.
One of these has received considerable media attention and is similar to UEFA’s Financial Fair Play regulations. The Profitability and Sustainability Rules allow the clubs to make a maximum cumulative loss of £105 million over three seasons before having to face sanctions from the league. The size of the permissible loss is significantly higher than in the UEFA regulations.
The other control that has received far less attention is called Short-Term Cost Control (STCC). This regulation places limits on the extent to which clubs can increase their total wage bill. It operates from 2013–14 to 2015&ndash16: i.e. it covers the same three years as the current TV deal. For the 2013–14 season it worked in the following way.
If teams had a wage bill of less than £52 million they faced no restrictions on their spending on players’ salaries. Only Crystal Palace (£46 million) and Hull City (£43 million) fell into this category. Unsurprisingly, the five biggest spending clubs, Man Utd, Man City, Chelsea, Arsenal and Liverpool, had much greater wage bills of £215m, £205m, £192m, £166m and £144m respectively.
Any of the 18 teams that exceeded the £52m limit would still not face sanctions if their wage bill increased by £4 million or less. For example, Stoke City’s wage bill only increased from £60m to £61m, while Tottenham Hotspur’s increased from £96m to £100m. Some clubs actually managed to reduce their total wage bill, including the champions, Manchester City, which managed to lower its from £233m to £215m.
However, there were still 12 teams with a total wage bill that was greater than £52 million in 2013–14 and which had increased by more than £4 million on the previous year. For these teams not to face any sanctions, they had to prove to the EPL that any of the increase above £4 million was either due to player contracts entered into before January 2013 or could by financed from the following two sources.
• Club Own Revenue Uplift
• Profit from player transfers
Whereas the profit from player transfers is straightforward, the ‘Club Own Revenue Uplift’ requires some explanation, as it excludes a very important part of teams’ incomes – Central Fund payments.
Some revenues earned by clubs in the EPL are referred to as ‘Central Fund payments’. These are, in effect, income payments from money that is raised centrally by the EPL on behalf of the clubs and then distributed to the teams using an agreed formula. The majority of the revenue generated under this category is from the broadcast deals, although some commercial income, such as the sponsorship of the league, also falls under this category. For some teams the money raised from Central Fund payments makes up the majority of their revenue.
‘Club Own Revenue’ in STCC calculations refers to all revenues other than those from Central Fund payments. This includes a number of income streams that the club has more direct control over. They include:
• Gate money/other match-day revenue
• Commercial deals negotiated by the individual club
• Income from playing in European competitions, including TV revenue.
The uplift refers to increases in revenue from these sources compared to 2012–13.
For example, assume a club has made no profit from its transfer dealing and did not enter into any significant player contracts prior to January 2013. If this club’s wage bill increased from £100m in 2012–13 to £110m in 2013–14 then it would have to provide evidence to show that £6m of this increase could be financed from growth in its Club Own Revenue. In other words, it would have to demonstrate how its income from gate money, commercial deals and playing in Europe was at least £6m higher in 2013–14 than it had been in 2012–13.
It will be interesting to see if (1) the profitability of the clubs continues to improve in future years and (2) the STCC regulations are extended when the new broadcast deal comes into effect in 2016–17.

John Nash was one of the pioneers of game theory and in 1994 was awarded the Nobel prize in economics for his work in this field. He was also the subject of the 2001 film, A beautiful mind, where the young John Nash was played by Russell Crowe, for which he won an Oscar.
Tragically, John Nash and his wife were killed in a car crash on May 23: he was 86 years old. Since his death there have been many tributes paid to him and his work.
As a student of economics you will almost certainly have studied the concept of a Nash equilibrium: a situation where everyone makes their best choice, given the choices of the other ‘players’ in a ‘game’. But a Nash equilibrium is not in the collective best interests of the participants in a non-cooperative game.
This is a very different concept of equilibrium from the simple equilibrium in a perfectly competitive market. In fact, in the complex world of strategic decision making, where firms are constantly looking at their rivals’ behaviour and possible reactions to their own behaviour, there are all sorts of Nash equilibria which are clearly sub-optimal. Competition may be highly destructive.
The following obituaries look at Nash’s contribution to the development of economics. As the Bloomberg article states:
The game theory concepts that Nash’s math[s] brought to the field were a true paradigm shift in economics. Macroeconomists, who continue to use the old Walrasian notion of equilibrium typically engage in hand-waving about how the macroeconomy is too big for strategic interactions to matter. But most of the economics profession has gradually shifted toward Nash equilibrium. The 2014 Nobel winner, Jean Tirole, is emblematic of the new economics. And many of the biggest successes in applied economics, like the auctions that power Google’s advertising, rely on Nash’s technique.
Do we owe him as much as Adam Smith?

Many of the major industries in Australia are oligopolies/oligopsonies. Examples include banking, telecoms, supermarkets, insurance and iron ore. The dominant firms in these markets have been accused of exploiting their market power, both in charging high prices to consumers and driving down the prices paid to suppliers. The result, it is claimed, is that they have been making excessive profits.
But things may be changing. With the rise of online trading, barriers to entry in these markets have been falling. Many of the new entrants are established firms in other countries and hence already have economies of scale.
The first article below examines the challenge to established oligopolists in Australia.

Over 90% of UK households buy their gas and electricity from one of the ‘big six’ energy suppliers – British Gas (Centrica), EDF, E.ON, npower (RWE), Scottish Power (Iberdrola) and SSE. The big six are currently being investigated by the Competition and Markets Authority (CMA) for possible breach of a dominant market position.
An updated ‘issues statement‘ summarises the investigation group’s initial thinking based on the evidence it has received. In paragraph 16 it states:
Comparing all available domestic tariffs – including those offered by the independent suppliers – we calculate that, over the period Quarter 1 2012 to Quarter 2 2014, over 95% of the dual fuel customers of the Six Large Energy Firms could have saved by switching tariff and/or supplier and that the average saving available to these customers was between £158 and £234 a year (depending on the supplier).
Between 40% and 50% of customers have been with a supplier for more than 10 years. The companies are thus accused of exploiting these ‘loyalty’ customers, many of whom are too busy or ill-informed to switch to an alternative supplier. According to the uSwitch article below:
This is a particular issue for the most vulnerable of customers, including the elderly, who view switching as ‘impossible’.
But the elderly were not the only consumers losing out; the CMA found that those customers most likely to be on expensive standard tariffs were less educated, or on lower incomes, or single parents, and did not necessarily have access to the Internet.
And the problem of penalising ‘loyalty’ customers who do not shop around applies in other industries, most notably banking. People who regularly switch savings accounts can get higher interest rates, often for a temporary ‘introductory’ period. Similarly, people who regularly transfer credit card debt from one card to another can take advantage of low interest rate, or even zero interest rate, deals for an introductory period.
Returning to the energy industry. Is the problem one of oligopoly? Do the big six have too much market power and, if so, what can be done about it? Should they be split up? Should regulation be tightened? Should new entrants be encouraged and, if so, what specific measures can be taken? The following articles explore the issues and possible policies.

A Greek exit from the euro (dubbed ‘Grexit’) is seen as undesirable by most Greeks and by most politicians in the rest of Europe. The optimum for both sides collectively would be a compromise, which saw more modest cuts by Greece and the eurozone remaining intact. By both sides seeking to maximise their own position, the Nash equilibrium is certainly not the best outcome.
But while the endgame is being played out by politicians, people in Greece are suffering. Policies of severely depressing aggregate demand to turn a large budget deficit into a primary budget surplus have led to the economy shrinking by 26%, overall unemployment of 27% and youth unemployment of over 60%. The Greeks truly believe themselves to be stuck between a rock and a hard place.
