The Paris Climate Change Conference (COP21) is under way. At the opening on November 30, 150 Heads of State gathered in Paris, most of whom addressed the conference. With representatives from 195 countries and observers from a range of organisations, the conference is set to last until 11 December. Optimism is relatively high that a legally binding and universal agreement will be reached, with the aim of keeping global warming below 2°C – what is generally regarded as a ‘safe’ limit.
But although it is hoped that a successor to the Kyoto Protocol of 1997 will be put in place, there are many problems in getting so many countries to agree. They may all wish to reduce global warming, but there is disagreement on how it should be achieved and how the burden should be shared between countries.
There are several difficult economic issues in the negotiations. The first is the size and impact of the external costs of emissions. When a country burns fossil fuels, the benefits are almost entirely confined to residents of that county. However, the environmental costs are largely external to that country and only a relatively small fraction is borne by that country and hardly at all by the polluters themselves, unless there is a carbon tax or other form or penalty in place. The problem is that the atmosphere is a common resource and without collective action – national or international – it will be overused.
The second problem is one of distribution. Politicians may agree in principle that a solution is necessary which is equitable between nations, but there is considerable disagreement on what is meant by ‘equitable’ in this context. As the third Guardian article below puts it:
The most important hurdle could be over whether industrialised countries like the US, UK and Japan, which have contributed the most to the historical build-up of emissions, should be obliged to cut more than developing countries. India, on behalf of many poor countries, will argue that there must be “differentiation” between rich and poor; but the US wants targets that are applicable to all. A collision is inevitable.
A third problem is that of uncertainty. Although there is general agreement among scientists that human action is contributing to global warming, there is less agreement on the precise magnitude of the causal relationships. There is also uncertainty over the likely effects of specific emissions reductions. This uncertainty can then be used by governments which are unwilling to commit too much to emissions reductions.
A fourth difficulty arises from the intertemporal distribution of costs and benefits of emissions reductions. The costs are born immediately action is taken. Carbon taxes or charges, or subsidies to renewables, or caps on emissions, all involve higher energy prices and/or higher taxes. The flows of benefits (or lower costs), however, of reduced emissions are not likely to be fully experienced for a very long time. But governments, whether democratic or dictatorships, tend to have a relatively short time horizon, governed by the electoral cycle or the likelihood of staying in power. True, governments may not be solely concerned with power and many politicians may have genuine desires to tackle climate change, but their political survival is still likely to be a major determinant of their actions.
Of course, if there is strong public opinion in favour of action to reduce emissions, governments are likely to respond to this. Indeed, all the expressions of public support for action ahead of the conference from all around the world, do give some hope for a strong agreement at the Paris conference. Nevertheless, there is still widespread scepticism in many countries over the relationship between human action and climate change, and many argue that the costs of policies to tackle climate change exceed the benefits.
Game theory can shed some insights into the difficulties ahead for the negotiators. The global optimum may be for a strong agreement, binding on all countries. The Nash equilibrium, however, may be a situation where countries push for their own interests at the expense of others, with the final agreement being much more minimalistic.
There do, however, seem to be more reasons to be cheerful at this summit that at previous ones. But negotiations are likely to be hard and protracted over the coming days.

There is a select group of countries (areas) that have something in common: the USA, the UK, Japan and the eurozone. The currency in each of these places is one of the IMF’s reserve currencies. But is China about to enter the mix?
The growth of China has been spectacular and it is now the second largest economy in the world, behind the USA. It is on the back on this growth that China has asked the IMF for the yuan to be included in the IMF’s basket of reserve currencies. The expectation is that Christine Lagarde, the IMF’s Managing Director, will announce its inclusion and, while some suggest that the yuan could become one of the major currencies in the world over the next decade following this move, others say that this is just a ‘symbolic gesture’. But that doesn’t seem to matter, according to Andrew Malcolm, Asia head of capital at Linklaters:
“The direct impact won’t be felt in the near term, not least because implementation of the new basket won’t be until Q3 2016. However the symbolic importance cannot be overlooked…By effectively endorsing the renminbi as a freely useable currency, it sends a strong signal about China’s importance in the global financial markets.”
Concerns about the yuan being included have previously focused on China’s alleged under-valuation of its currency, as a means of boosting export demand, as we discussed in What a devalued yuan means to the rest of the world. However, China has made concerted efforts for the IMF to make this move and China’s continuing financial reforms may be essential. The hope is that with the yuan on the IMF’s special list, it will boost the use of the yuan as a reserve currency for investors. It will also be a contributor to the value of the special drawing right, which is used by the IMF for pricing its emergency loans.
Although the Chinese stock market has been somewhat volatile over the summer period, leading to a devaluation of the currency, it is perhaps this move towards a more market based exchange rate that has allowed the IMF to consider this move. We wait for an announcement from the IMF and the articles below consider this story.

Questions
- What is meant by a reserve currency?
- Why do you think that the inclusion of the yuan on the IMF’s list of reserve currencies will boost investment in China?
- One of the reasons for the delay in the yuan’s inclusion is the alleged under-valuation of the currency. How have the Chinese authorities allegedly engineered a devaluation of the yuan? To what extent could it be described as a ‘depreciation’ rather than a ‘devaluation’?
- Look at the key tests that the yuan must pass in order to be included. Do you think it has passed them given the report produced a few months ago?
- The weighting that a currency is given in the IMF’s basket of currencies affects the interest rate paid when countries borrow from the IMF. How does this work?
On Monday 23rd November, the US based pharmaceutical business Pfizer (producer of Viagra) announced that it had reached a $160 billion deal to acquire the Irish based pharmaceutical business Allergan (producer of Botox). If it is successful it will be the third largest deal in takeover history.
In a previous blog on this website a number of reasons were discussed to explain why businesses may engage in mergers and acquisitions (M&As) Are large mergers and acquisitions in the interests of the consumer . These include market power, access to growing markets, economies of scale and reducing x-inefficiency. One of the interesting things about the Pfizer and Allegan deal is the importance of another factor that was not discussed in the article – tax avoidance.
Rates of corporation tax vary considerably between countries and may deter some businesses from operating in the US where it is at the relatively high level of 35%. This compares with a rate of 20% in the UK, 12.5% in Ireland and 0% in Bermuda. The global average rate is 23.7% whereas the average across EU countries is 22.2%.
However, a far bigger incentive for a US firm to merge with or acquire businesses in other countries is the unusual way the US authorities tax profits. Most countries use a territorial system. This means that tax is only paid on the profit earned in that country. For example if a UK multinational business has subsidiaries in other countries it only pays corporation tax in the UK on profits earned in the UK. The profits earned by its subsidiary businesses would be taxed at the rate set by the government in the country where they were located.
The US authorities use a worldwide system. This means that profits earned by a subsidiary in another country are also taxed in the US. This is best explained with the help of a simple numerical example.
Assume a US multinational earns $100,000 in profits from a subsidiary based in Ireland. These profits will be taxed in Ireland at the rate of 12.5% and the company would have to pay $12,500 to the Irish government. If that profit was returned to the US it would be taxed again at a rate of 22.5%: i.e. 35% – 12.5%. The company would have to pay the US authorities $22,500.The worldwide system means that the total rate of tax paid by the firm is 35% but it is split between two different countries. If the territorial system was used, the firm would only pay the $12,500 to the Irish government.
So how could M&As change things? If an M&A enables a US multinational business to change its country of incorporation (i.e. move the address of its headquarters) from the US to another country that operates a territorial system its payments will fall. This is sometimes referred to as tax inversion. As the Bloomberg columnist Matt Levine stated:
If we’re incorporated in the U.S., we’ll pay 35 percent taxes on our income in the U.S. and Canada and Mexico and Ireland and Bermuda and the Cayman Islands, but if we’re incorporated in Canada, we’ll pay 35 percent on our income in the U.S. but 15 percent in Canada and 30 percent in Mexico and 12.5 percent in Ireland and zero percent in Bermuda and zero percent in the Cayman Islands.
As a result of the merger with Allergan, Pfizer will move the address of its headquarters to Ireland even though its global operations and executives will still be based in New York. It has been estimated that this will generate a one off tax saving of $21 billion as Pfizer would avoid having to pay US taxes on $128 billion of profits generated by its non US subsidiaries.
A number of US politicians have condemned the proposed deal. For example Hilary Clinton stated:
This proposed merger, and so called inversions by other companies, will leave US taxpayers holding the bag.
Twenty US companies have moved their headquarters to countries that operate a territorial system of taxation since 2012. These include Burger King’s move to Canada and Medtronic’s move to Ireland.
The US government has tried to tighten the rules but the two major parties disagree about how to deal with the problem.

Jim Slater, who has just died at the age of 86, was a tycoon of the 1970s, probably unknown to most reader of this blog. But his legacy lives on and many will question whether the actions of the banking sector and big business today is a reflection of the lessons that were not learnt 40 years ago.
Slater was a businessman: perhaps the businessman in the 1970s, building up a company that in today’s money and the height of its success, would have been worth billions. Buying and selling companies, asset stripping and investing created Slater Walker, which shot to success and then crumbled to failure, taking with it a bailout from the Bank of England of £110 million. You might look at that figure and compare it with the bail outs of more recent times and think – peanuts. But think about how prices have changed and convert £110 million into today’s money and that’s a hefty bail out. A key question is whether the willingness of the government and Bank of England to bail out key banks and financial sector businesses has encouraged the irresponsible lending that led to the credit crunch. Was there a moral hazard? Had Slater Walker been left to fail, would the world look a slightly different place?
Perhaps a little extreme, but I wonder, if we were to look back over the past 50 to 60 years, whether we would find other cases of key businesses being bailed out, which set a precedent for other companies to grow, without necessarily taking full responsibility for it. Jim Slater will certainly leave a legacy behind him .
Jim Slater and the warning from the 1970s that we ignored BBC News, Jonty Bloom (20/11/15)
Questions
- What is meant by asset stripping?
- If a company like Slater Walker had not been bailed out, do you think the economy would have suffered?
- If Slater Walker had been left to fail, would that have changed the business model of some of our largest banks and reduced the chance of a financial crisis 40 years later?
- Do you think the concept of moral hazard is relevant here?
The price of petrol is of interest to most families, occupying a key component of weekly expenditure. Over the past decade, it has fluctuated significantly, from around 85p per litre to over £1.40. More recently, prices have been around £1.03 to £1.10, depending on the brand and the location. But, will we see prices falling below that magical £1 per litre mark?
We have recently seen a 2p drop in wholesale fuel prices and it is this which has led to speculation about a further fall in prices at petrol stations to below £1. This, according to the RAC, has a ‘very good chance’ of happening.
A key determinant of petrol prices is the market price for crude oil and it is this which has been contributing towards the low petrol prices. As these prices filter through to the pumps, the RAC suggests that prices may once again come down. Furthermore, with some of the key petrol stations being operated by the big supermarkets, competition for sales and hence on prices may be fierce.
But, now let’s consider another well-informed organisation. According to the AA, the chances of petrol prices falling below £1 are ‘remote’. So, who should we believe? In fact, we can probably believe both. The market price may not fall below £1, but in the run-up to Christmas and in the start of the New Year, we may well see petrol on sale for under £1 as a means to entice shoppers or, as the AA has said, as a ‘marketing gimmick’. As you can see from the picture, Asda has dropped the price below £1 per litre in some of its petrol stations.
You might think this is a little strange, given the inelastic nature of the demand for petrol: after all, as prices of petrol rise and fall, I for one, don’t change my demand. This is also confirmed by HMRC, which reports that total petrol consumption is falling despite the low prices. But, it’s probably less about changing your total demand for petrol and more about from where you buy that total demand. For any one petrol station, the demand may be relatively elastic. It is this which may fuel a price war on petrol. The following articles consider this.

The Paris Climate Change Conference (COP21) is under way. At the opening on November 30, 150 Heads of State gathered in Paris, most of whom addressed the conference. With representatives from 195 countries and observers from a range of organisations, the conference is set to last until 11 December. Optimism is relatively high that a legally binding and universal agreement will be reached, with the aim of keeping global warming below 2°C – what is generally regarded as a ‘safe’ limit.
There are several difficult economic issues in the negotiations. The first is the size and impact of the external costs of emissions. When a country burns fossil fuels, the benefits are almost entirely confined to residents of that county. However, the environmental costs are largely external to that country and only a relatively small fraction is borne by that country and hardly at all by the polluters themselves, unless there is a carbon tax or other form or penalty in place. The problem is that the atmosphere is a common resource and without collective action – national or international – it will be overused.
A fourth difficulty arises from the intertemporal distribution of costs and benefits of emissions reductions. The costs are born immediately action is taken. Carbon taxes or charges, or subsidies to renewables, or caps on emissions, all involve higher energy prices and/or higher taxes. The flows of benefits (or lower costs), however, of reduced emissions are not likely to be fully experienced for a very long time. But governments, whether democratic or dictatorships, tend to have a relatively short time horizon, governed by the electoral cycle or the likelihood of staying in power. True, governments may not be solely concerned with power and many politicians may have genuine desires to tackle climate change, but their political survival is still likely to be a major determinant of their actions.
