In December, most of the countries of the world will meet in Paris at the 21st annual United Nations Conference of the Parties (COP) on climate change. COP21 ‘will, for the first time in over 20 years of UN negotiations, aim to achieve a legally binding and universal agreement on climate, with the aim of keeping global warming below 2°C.’
When the Copenhagen conference (COP15) ended in disagreement in 2009, few people thought that the increase in renewable energy would be anything like sufficient to prevent global temperatures rising more than 2°C. But things have dramatically changed in the intervening six years.
Solar power and other renewables have increased dramatically and the technology for the cleaner burning of fossil fuels, including carbon capture and storage, has developed rapidly.
But perhaps the most important change has been the attitudes of governments. No longer is it a case of Europe and other developed countries moving in the direction of renewables, while developing countries, and, in particular, China and India, argue that their economic development requires a rapid expansion of coal-fired power stations. Now China, India and many other emerging countries are rapidly developing their renewable sectors. This is partly driven by the fall in the costs of renewables and partly by worries that climate change will directly effect them. Now the ‘pro-coal’ countries are in a minority.
And industry is realising that significant profit is to be made from the development and installation of power plants using renewable energy. This is driving both R&D and investment. As the Telegraph article, linked below, points out, in 2009 ‘the International Energy Agency (IEA) was still predicting that solar power would struggle to reach 20 gigawatts by now. Few could have foretold that it would in fact explode to 180 gigawatts – over three times Britain’s total power output – as costs plummeted, and that almost half of all new electricity installed in the US in 2013 and 2014 would come from solar’.
So is this a good news story? Will real progress be made at COP21 in Paris? The articles explore the issues.

Mario Draghi, the ECB President, has indicated that the ECB is prepared to engage in further monetary stimulus. This is because of continuing weaknesses in the global economy and in particular in emerging markets.
Although the ECB at its meeting in Malta on 22 October decided to keep both interest rates and asset purchases (€60 billion per month) at current levels, Mario Draghi stated at the press conference that, at its next meeting on December 3rd, the ECB would be prepared to cut interest rates and re-examine the size, composition and duration of its quantitative easing programme. He stopped short, however, of saying that interest rates would definitely be cut or quantitative easing definitely increased. He said the following:
“The Governing Council has been closely monitoring incoming information since our meeting in early September. While euro area domestic demand remains resilient, concerns over growth prospects in emerging markets and possible repercussions for the economy from developments in financial and commodity markets continue to signal downside risks to the outlook for growth and inflation. Most notably, the strength and persistence of the factors that are currently 
slowing the return of inflation to levels below, but close to, 2% in the medium term require thorough analysis.
In this context, the degree of monetary policy accommodation will need to be re-examined at our December monetary policy meeting, when the new Eurosystem staff macroeconomic projections will be available. The Governing Council is willing and able to act by using all the instruments available within its mandate if warranted in order to maintain an appropriate degree of monetary accommodation.”
Mario Draghi also argued that monetary policy should be supported by fiscal policy and structural policies (mirroring Japan’s three arrows). Structural policies should include actions to improve the business environment, including the provision of an adequate public infrastructure. This is vital to “increase productive investment, boost job creation and raise productivity”.
As far as fiscal policies are concerned, these “should support the economic recovery, while remaining in compliance with the EU’s fiscal rules”. In other words, fiscal policy should be expansionary, while staying within the limits set by the Stability and Growth Pact.
His words had immediate effects in markets. Eurozone government bond yields dropped to record lows and the euro depreciated 3% against the US dollar over the following 24 hours.

After initial resistance, the brewer SAB Miller last week agreed to a merger with Anheuser-Busch InBev (AB InBev). The merging parties own over 400 brands between them. These include Budweiser, Stella Artois and Beck’s, which are owned by AB InBev, and Peroni and Grolsch by SAB Miller. Furthermore, they are currently the number one and two firms in the market respectively. If the merger goes ahead the new entity would control almost one third of global beer production.
This merger represents the continuation of AB InBev’s aggressive expansion plans through mergers and acquisitions as it follows its merger with Interbrew in 2004 and with InBev in 2008. It seems that one key attraction of a merger with SAB Miller is its dominant position in rapidly growing African markets.
A second motivation for the merger appears to be an attempt to counter the rise of small independent craft beer producers. For example, in the USA craft beer’s share of the market has grown from 5 to 11% since 2011. It has been suggested that the leading breweries combining forces represents one of several strategies being used to try to counter the threat of craft breweries. Additional strategies include creating their own craft products that are marketed as independant products and attempting to buy-up craft beer producers. For example, in 2011 AB InBev purchased the Goose Island brand.
Commenting on the planned merger between SAB Miller and AB InBev, a spokesman for the Campaign for Real Ale group expressed concern that:
independent beers may find it harder to get space in pubs and supermarkets because of the increased market presence of AB InBev.
Given the market positions of SAB Miller and AB InBev, it is likely that their merger will face considerable scrutiny by competition agencies in a number of jurisdictions. In fact it has been reported that plans have already been set in motion to sell SAB Miller’s interests in the USA to try to placate potential concerns from competition agencies in the USA and China.
Interestingly, SAB Miller has also protected itself by negotiating a clause that requires AB InBev to pay it $3bn if the deal falls through, for example on competition grounds. It remains to be seen what conditions competition authorities will require before the merger can go ahead and it is even possible they will try to completely block the deal.

- How serious a threat do you think independent craft beer producers are to the leading breweries?
- Outline some of the factors competition agencies will look at when they consider the merger between SAB Miller and AB InBev.
- Why might AB InBev have been willing to agree to pay a fee to SAB Miller in the event of the merger falling through?
One of the most controversial policy changes being made by the Conservative government relates to the tax credit system. For many years, the tax and benefits system in the UK has come in for significant criticism. It has been described as overly complex, a system that doesn’t reward work and yet a system that doesn’t provide sufficient incentives to move off benefits and into work.
The changes that the government is proposing are wide-ranging and focused in part on reducing the deficit. With changes to tax thresholds, the introduction of the National Living Wage (NLW) and changes to the thresholds at which tax credits are available, the Treasury suggests that £4.5 billion will be saved per year. It also says that most working families will be made better off. However, the IFS suggests that some families could lose up to £1000 per year following the changes.
In addition to these changes, the amount of tax-free childcare is also set to increase, helping those households with young children
Tax credits are designed to help low income families and working tax credit, in particular, is aimed to encourage people to move into work. A key change to this tax credit will see the threshold at which the recipient’s payments of this benefit begin to decline move from £6420 to £3850. The withdrawal rate – the rate at which the benefit is withdrawn – will also be increased.
The idea is that this will help to target the benefit more tightly – make it more vertically efficient. But, the concern is that this will also mean that low-income working households are worse off, despite the introduction in April 2016 of the National Living Wage. The Chancellor suggests that anyone who is working full time will be better off following these changes and that as such the changes will actively encourage work and lead to an increase in the supply of labour. This, the government argues, is a good policy for the working population, tax payers and for the wider economy.
This policy will remain controversial, with changes set to come in from 2016 and then 2017. It is certainly difficult to assess the impact of these changes on households and part of that stems from the complexities of the existing system, which mean that some households are eligible for some benefits, whereas others are not.
The final impact, if such changes are approved, will only be known once the tax credit changes are implemented. The House of Lords will vote on whether to ‘kill’ the tax credit cuts and Mr. Osborne, despite some concerns from Conservative back-benchers has said he is ‘comfortable’ with the policy and that the House of Lords should respect the views of the other house. Until we see the results of the vote and, even then, the impact of the changes on households, both sides will continue to produce data and estimates in support of their views.

Obesity is on the rise, especially in children. With all the attendant health problems, concern is growing and various policies have been proposed to try to tackle the problem. One such policy is a sugar tax. This could be either a universal tax on sugar in food products or a tax just on soft drinks, many of which are very high in sugar – typically about seven teaspoons in a can or individual bottle.
Currently the issue is being considered by the UK’s Parliamentary Health Select Committee. Jamie Oliver, the TV chef and restaurateur, argued strongly before the committee in favour of a sugar tax on fizzy drinks. He has already imposed a levy on soft drinks with added sugar in his restaurants. He maintained that it was not just the higher price from a sugar tax that would deter consumption of such drinks, but it would send out an important message that too much sugar is bad for you.
Two days later, Dr Alison Tedstone appeared before the committee. She is chief nutritionist at Public Health England. PHE has been carrying out research into obesity and ways of tackling it. It has reviewed two types of evidence: experimental data on the effects of imposing higher prices on products with added sugar; and the effects of policies pursued in other countries. She stated to the committee that ‘universally all the evidence shows that the tax does decrease consumption’ and that ‘the higher the tax increase, the greater the effect’.
The government was not planning to publish the report at this stage, but under considerable pressure agreed to its publication.
The articles look at the prospects for a sugar tax, its likely effects if one were introduced and at the politics of the situation, which are likely to result in such a tax being rejected.

- How is the concept of price elasticity of demand relevant to the effectiveness of imposing a sugar tax?
- What would determine the incidence of such a tax between food and drink manufacturers and consumers?
- Would such a tax be progressive, regressive or neutral? Explain.
- What other policies could be pursued to discourage the consumption of sugar? Discuss their likely effectiveness and compare them with a sugar tax.
- What externalities are involved in sugar consumption? How would you set about measuring them? Should a sugar tax be set at a rate that internalises the estimated externalities?
- Examine the objections to imposing a sugar tax.
