Here is an updated version of the WEESTEPS approach to economics evaluation designed to boost the evaluation scores and exam results for AS and A2 students. Paul Bridges is the mastermind behind this superb approach to evaluation - it gives you some great pointers about the evaluative approaches that can be used. Works well for micro and macro - but particularly when you have to evaluate a specific policy intervention in a market / industry / or a macro policy discussion.

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.

Food prices are now rising by up to 10% a year in Britain and Europe and a new forecast from the United Nations predicts that prices can be expected to rise at least 40% in the next decade. Whilst conventional theories of changes in supply and demand conditions can be used to explain some of the increase in food prices, many economists are concerned that speculation by hedge funds and other investors has amplified the natural volatility of prices driving food prices away from fair values and contributing to a huge rise in global food poverty and hunger. These days, cocoa, fruit juices, sugar, staples, meat and coffee are all now global commodities, along with oil, gold and metals.
Is this the moment to legislate to limit the scope for speculative activity in food markets? The video below provides an excellent introduction to speculation in food markets - it features Neil Kellard, Professor in Finance at the University of Essex

A good example to discuss of government intervention into agricultural markets - in this case Thailand’s government have intervened in the market to buy unmilled rice at 15,000 Thai baht per metric tonne, which is a 50% premium on the current market rate. A good discussion of the possible impacts can be found, with a discussion of the economic rationale/consequences of it, here.
Unit 1 Micro: Economics of Volatile Corn Prices
Corn is a soft commodity along with the likes of coffee, tea and rubber. Referred to as “yellow gold”, corn is used in products ranging from cereals, snack foods, salad dressings, soft drink sweeteners, chewing gum and peanut butter. Little wonder that shifts in the world price of corn can have a noticeable effect on the prices that we may for many popular foods and drinks.
The world’s appetite for corn is strong. In recent months there has been a surge in the global price of corn, indeed at the end of June 2011, corn prices were up 74 per cent on a year earlier. Super-high prices affect the price of feed for livestock farmers and eventually lead to more expensive foodstuffs for consumers, including millions of people in the world’s poorest countries exposed to persistent and life-shortening food poverty. Robert Zoellick, President of the World Bank has said that high and volatile food prices are “the single gravest threat” facing developing countries at the current time.

AS Micro: Fears over a century of hunger
Nigel Cassidy reports in this video from BBC news on fears that the world faces “a century of hunger” if the international community cannot agree on new rules regarding food prices. Food security is a hugely important global economic, political and social issue and one of the best resources for keeping up to speed on this is the Guardian’s dedicated page of articles. Here is the link. Check the links at the bottom of the blog for past articles on this topic.
AS Micro: Commodity Prices
The economics of volatile commodity prices are a staple feature of many AS micro papers - it gives you a chance to apply your understanding of supply and demand factors and the importance of elasticities of demand and supply in explaining price movements. And also understand some of the consequences of volatile price and output movements for different stakeholders - including consumers, producers and the government. This BBC news article takes a look at the likely direction of world commodity prices and embraces a number of different markets that have appeared on exam papers in the past - so a useful exercise to test your revision is to read through and see how much you get first time. I have put a revision presentation on price volatility in markets on my web site - available here (it does the job for a really good AS micro answer)

Will a collapse in global cocoa production bring an end to chocolate as an affordable treat and giver of blood sugar? This article from the Independent today was timely as I am teaching price volatility in commodity markets in my AS micro class as a prelude to discussions abour price intervention strategies such as maximum prices / buffer stock schemes etc. I have attached my class homework as a word file in case it is of use to colleagues.
Cocoa Economics (AS micro)

Here is a highly relevant section from a new report from Commodities Now
“World food prices have been trending higher as emerging markets have increased their share of global food demand due to rising populations and incomes. Food products are having to compete for finite resources such as water, land and fertiliser inputs and are increasingly being used for alternative applications such as bio-fuels. As an example, ethanol now accounts for approximately one-third of annual corn output in the US, up from 5% a decade ago.”

AS Economics Revision - Stocks and Prices
In many AQA AS microeconomics exams, the focus of the stimulus materials is on a market or inter-related markets where prices have changed and which raise interesting questions about the causes of price volatility and arguments for and against some form of intervention.
One aspect for students to consider is the relationship between stocks of a product and the direction of changes in market prices.
Stocks (also known as inventories) are products ready for sale but not yet purchased. They might include finished output 9such as new cars) or inventories of components, work in progress and raw materials.
Movements in inventories can trigger price changes. In our two examples we focus on the market for copper and for crude oil. In both cases look to see how prices move when there is a noticeable reduction in stock levels, perhaps reflecting a rise in market demand set against an inelastic short-run supply. When stocks are low, prices are bidded up not least in commodities markets where speculators look to make speculative purchases when they feel that the balance of power in a market is tilting in favour of the seller (i.e there is excess demand and stocks are declining).
A market where inventories are high is one where, ceteris paribus, there is downward pressure on equilibrium prices.
Spare swine flu vaccine - government failure or good planning?
Is this an example of government failure, or good planning?
The answer to that probably lies in the future, next winter, when we will discover whether the buffer stocks of 34 million unused swine flu jabs is needed or not.
In the emergency last summer the government contracted to buy 120 million jabs from the two manufacturers, GlaxoSmith Kline and Baxter, but then reduced the order to just 44 million as the emergency petered out. Only 6million of those have actually been used, nearly 4 million are being given to the World Health Organisation for use in Africa, leaving 34 million on the shelf.
