Unit 1 Micro: Brazilian coffee buffer stock hit by falling prices

Just a few years ago, Conab, Brazil’s official crop bureau was busy buying up surplus supplies of Brazilian coffee to support the weak global price of high quality arabica coffee. Over the years Conab has accumulated large stockpiles of coffee in their warehouses. Some estimates put the 2002-2003 stockpile purchases at just under 4 million kg together with 1.9m kg bought in 2007-08. The 2009-10 buffer stock purchases are much higher - exceeding 91 million kg. That is a lot of coffee to hold in reserve!
In theory a buffer stock scheme should be profitable when stocks are purchased at a low price and then off-loaded onto the market when prices are higher. Indeed Conab was planning just such a sale earlier this year before favorable weather and the speculators intervened. Better than expected coffee harvests in Brazil have prompted a steep fall in coffee prices and the buffer stock has postponed an intervention into the market.
The coffee price drop is a far cry from last year. Arabica coffee prices hit a 34-year high in March 2011 amid fears of a shortage. Since then, much has changed. From a peak of $3.089 per pound nearly a year ago, prices are down roughly 40 per cent to $1.851 per pound.
Inventories of high-quality beans remain low, but the threat of a shortage has vanished as Brazil is expected to see a bumper harvest this year. This is in contrast to a number of other coffee-growing countries - but Brazil remains a dominant force in the market.

Professor David Blanchflower didn’t pull his punches when he was a member of the Bank of England’s Monetary Policy Committee and he is making his mark once more with an attack on what he views as the Coalition government’s lacklustre approach to tackling youth unemployment. Blanchflower is reported in the Guardian as wanting zero national insurance contributions for employers who take on younger workers in depressed regions and localities. And he wants greater investment in vocational education in schools and colleges with the school-leaving age raised to 18.

Teresa May has copied Nicola Sturgeon’s proposals for minimum prices of alcohol which appeared in Scotland last year. Last year’s budget had significant increases in excise duties on stronger beer, lager and cider.
This resource from the Centre For Policy Studies may help pupils and teachers to evaluate different forms of government intervention and their effectiveness.
Budget 2012 - analysis with evidence
As ever, there are loads of sources that students can use to analyse the Budget and to extract pieces of Evidence for the Examples they will need to add depth to their analysis in essays. Those who are attending the current round of revision workshops will recognise this as a key part of ensuring that they write essays which PEEL the answer (each paragraph makes one Point, using Examples with Evidence, offering Evaluation and Linking to the question). As start points, I would suggest these sources which are reasonably free of opinions:
BBC website: Budget 2012 at a glance, Farewell 50p tax rate, and Over 65-s tax-free income freeze
The Guardian Budget 2012: welfare cuts, tax cuts too, but retreat on child benefit and for the visual learners a nice graphic version: Tax and spending plans visualised
Unit 1 Micro: The Tax on Beer
In the lead up to the 2012 Budget, this short BBC news video clip looks at the cost of a pint of beer and claims that some brewers have weakened their beer to avoid the higher excise duty on higher-strength drinks. There is a neat explanation of the breakdown of beer costs and students may be surprised to find out the amount of tax they pay if they drink a pint! About 95p from every pint goes to the government.
Higher taxes have been one factor bringing down consumption levels. There has been a 13 per cent decline in alcohol consumption per head in Britain since 2004. The percentage of men aged 16-24 who drank more than 21 units per week has fallen from 32 per cent to 21 per cent from 2005 to 2010

A new report headed up by Professor John Hills from the LSE highlights the growing risks of fuel poverty facing millions of people in the UK and especially those living in lower-income families. At present, the definition of fuel poverty based on whether a household needs to spend more than 10 per cent of its income each year on energy. But this measure has been criticised because it ignores the significant seasonal variation in energy bills and the financial distress that a really large bill can have on people with little or not savings to fall back on.

Here is a fresh attempt by the British government to breathe life into the moribund housing market. People in England are being offered financial help to climb onto or up the housing ladder as the government’s new mortgage indemnity scheme launches. Under the terms of the scheme, both the construction industry and taxpayers will act as co-guarantors on new homes bought by existing or first-time buyers. Will it work in boosting demand for new build homes? Is this scheme designed to help house-buyers or builders? Or is there a real risk of government failure?
Basics:
* Builders will pay 3.5 per cent of the price of the home
* Taxpayers will provide an additional guarantee of 5.5 per cent that will only be used if there is a major property crash.
* Mortgage lenders will be able to lend up to 95 per cent of the sale price which means new buyers in many instances will only need to find a five per cent deposit or £10,000 on a new £200,000 home. The typical deposit on a mortgage now is closer to £36,000
* The scheme is available on houses and flats valued under £500,000 in England only
Evidence of the dangers of protectionism
One of the dangers for a country implementing protectionist measures is the risk of retaliatory action. We have only to look at US-China trade relations to find plenty of evidence for this. The US objects to what they see as a Chinese policy of deliberately holding down the value of the yuan in order to boost Chinese exports. However, in addition to this they also object to government subsidies which the Chinese government give to some of their producers in order to help lower their production costs and so make their goods even more competitive in world markets.

Here is an example of the law of unintended consequences where unlikely side-effect is a thoroughly welcome positive spillover effect. Researchers are finding that the number of premature births and exceptionally under-weight babies in Scotland is falling - watch this video - and then consider why this might be happening.
Scotland was the first country in the UK to ban smoking in public places, followed by Wales, Northern Ireland and England in 2007. Several years on, nearly one-in-five of mothers to be still smoke - how sad.
Unit 1 Micro: 50 years of anti-smoking campaigns and awareness
No one is in any doubt that smoking kills and for half a century the Royal College of Physicians has been warning of the damaging health consequences of nicotine consumption and addiction. They continue to campaign for higher prices and tougher laws on advertising and packaging to curb consumption - even today one fifth of the adult population smokes. Smoking continues to kill around 100,000 Britons each year and unless smokers give up their habit, 100 million years of life will be lost in the UK, according to experts. Channel 4 news reports on changing social norms and the battle to change behaviour. A good historical perspective on information gaps.

The Economics of Climate Change - Stern 5 Years On
Lord Nick Stern tonight gave the first of three lectures on the ethics and economics of climate change as the annual lecture series in honour of Lionel Robbins started at the LSE.
It is over five years since the publication of the Stern Report and much has happened in the intervening period. Stern however was at pains to emphasise that his core message remained undimmed, namely that the costs of inaction are enormous but the costs of early action to cut emissions are manageable. We have seen in recent years rapid technological change much of which is hugely encouraging in taking us closer to de-coupling the relationship between production and consumption and carbon emissions. But more is needed, Stern is arguing in these three lectures for a new industrial revolution, a deep set of changes to production processes and technologies that happens across every sector. The economics and politics of how progress might be made in moving towards a new revolution will be the focus of the second and third lectures.
LECTURE 1 - Tuesday 21 February 2012
What we risk and how we should cast the economics and ethics
LECTURE 2 - Wednesday 22 February 2012
How we can respond and prosper
LECTURE 3 - Thursday 23 February 2012
How we can get there: building national and international action
Drink, drink, more drink
Students are often asked to weigh up policies to limit the over consumption of demerit goods like alcoholic drinks. This BBC article cited by Ben White considers some of them.
Most governments have used a combination of policies with varying levels of success. One policy option is the use of variable rates of Excise Duty. The March 2011 budget resulted in a rise in the duty on strong beers (above 7.5% alcohol) of 25%, and the duty on weak beers (below 2.8%) cut by 50%.

Here is a great little article on the Today programme’s website by Evan Davis, looking at the relative merits of Plan A - Austerity - vs Plan B - government spending. He takes the arguments of Jonathan Portes, director of the National Institute of Economic and Social Research, who believes that what’s required at the moment is a short term, temporary fiscal stimulus to boost output and jobs and of Roger Bootle, managing director of Capital Economics, who thinks it would be dangerous for the government to divert from its Plan A of spending cuts.

Public goods provide an example of market failure resulting from missing markets.
The characteristics of pure public goods are the opposite of private goods:
1. Non-excludability: The benefits derived from pure public goods cannot be confined solely to those who have paid for it. Indeed non-payers can enjoy the benefits of consumption at no financial cost – economists call this the ‘free-rider’ problem. With private goods, consumption ultimately depends on the ability to pay
2. Non-rival consumption: Consumption by one consumer does not restrict consumption by other consumers – in other words the marginal cost of supplying a public good to an extra person is zero. If it is supplied to one person, it is available to all.
3. Non-rejectable: The collective supply of a public good for all means that it cannot be rejected by people, a good example is a nuclear defence system or flood defence projects.
There are relatively few examples of pure public goods. Examples include flood control systems, some of the broadcasting services provided by the BBC, public water supplies, street lighting for roads and motorways, lighthouse protection for ships and also national defence services.

On 1st January this year, the EU introduced an Emissions Trading Scheme (ETS) which levies a charge on flights in EU airspace based on carbon emissions. They estimate that this will add between 2 and 12 euros to flight tickets. Airlines are required to purchase emissions permits, like utilities and heavy industry in the EU, and airlines that do not comply face fines of 100 euros for each tonne of carbon dioxide emitted for which they have not surrendered allowances. In the case of persistent offenders, the EU has the right to ban airlines from its airports.

Britain is one of the world’s biggest exporters of creative products - from live TV shows and music to books, arts, architecture and films the economy has built up an enviable global reputation for excellence and a growing trade surplus to aid our balance of payments.
Computer games falls squarely into this category but, according to TIGA - the trade association representing the UK’s games industry - unless there is renewed government support, the future of this sector is at risk. TIGA claims that the British games industry is suffering a significant ‘brain drain’ as talented programmers and artists leave the country to work abroad.

This blog provides a link to a new prezi presentation on the economics of solar subsidies - I have been using it as part of my teaching on aspects of environmental economics for Unit 3 AQA but it might also be useful for unit 1 market failure. I have kept theoretical diagrams out of it and plan to build up relevant analytical concepts such as economies of scale, consumer subsidies, economic and social welfare, government failure et al on a normal whiteboard rather than embed them into the Prezi. I hope it is useful.
