Ginsters is a large producer of pasties in Cornwall. Most of its ingredients come from Cornwall, but the pasties are sold throughout Britain. But, not surprisingly, they are also sold in Cornwall. In fact, there is a large Tesco virtually next door to the Ginsters’ pasty plant and, as you can imagine, it does a good trade in Ginsters’ pasties, pies and sandwiches. After all, they are a local product.
But are they delivered directly from the Ginsters’ factory? No they are not. In fact, they are sent by lorry to the Avonmouth distribution depot, some 125 miles away, only to be sent back again to the Tesco supermarket next door! So does it make economic sense to incur all the costs of transporting the pasties 250 miles only to end up virtually where they started?
It is a similar story with Rodda’s Cornish clotted cream. It is made with Cornish milk but is also sold nationwide. In this case it is transported some 340 miles to get to another Tesco supermarket virtually next door to the Rodda plant.
The following articles and podcast consider the logistics of manufactured food distribution, and ask whether private costs are the only thing that should be taken into account when judging the sense of the system.

Questions
- Why does Tesco’s distribution system for pasties, clotted cream and other products made in parts of the country away from large centres of population make sense in ‘conventional economic terms’?
- What economies of scale are there in pasty production and distribution?
- What externalities are involved in the distribution of Ginsters’ pasties?
- Consider the arguments for and against locating mass producers of food products nearer to the ‘centre of gravity’ of markets.
$8 billion – this is the likely cost of the BP oil leak, which spilled 206 million gallons of oil into the Gulf of Mexico. Whilst the oil leak has been stopped for some time, there were ongoing concerns that the leak would re-appear due to the underwater pressure. The cost of stopping the leak has been substantial, but BP will face further costs, as the company begins to pay out compensation.
$20 billion is the compensation that residents of the Gulf of Mexico will receive. Further to this, BP has said that it will invest more money in promoting the tourism industry there, which has suffered from the oil spill. However, what about the fishing industry? Although compensation will be paid for the losses incurred, will this continue in the long term? The oil may cause a loss in productivity in certain populations of sea-life. How will this impact us? If certain fish became scarcer, then their price will rise accordingly, whether you purchase the fish at a shop or have it as a meal in a restaurant. To make matters worse, the hurricane season has arrived in the affected areas, which will make the clean-up effort even harder.
As BP’s share price has fallen, individuals have suffered from lower dividends. Jupiter Income Trust had almost 10% of their portfolio invested in BP, which largely explains the 9 per cent drop in their payout.

Questions
- Which industries have been affected by the oil leak? Don’t think too close to home – look at the wider picture.
- Is the oil spill an example of a negative externality? Can it be illustrated on a diagram and, if so, how?
- What has happened to BP’s share price since the beginning of the oil spill? Put this on to a graph to trace the trend. Try to explain the changes in the share price using a demand and supply diagram.
- How would BP have calculated the compensation to be paid to residents of the Gulf of Mexico? Would cost–benefit analysis have been involved?
The prices of grains and other foodstuffs are rising rapidly. Wheat prices rose some 40 per cent in July and have continued to rise rapidly since. In June wheat futures were trading at around 450 US cents/bushel. By early September, they were trading at around 700 US cents/bushel. Global food prices generally rose by 5% over the two months July/August. And it’s not just food. Various other commodity prices, such as copper and oil, have also increased substantially.
At the beginning of September there were three days of food riots in Mozambique in protest against the 30% rise in the price of bread. Seven people were killed and 288 were injured. On 2 September Russia announced that it was extending a ban on wheat exports for another 12 months following a disastrous harvest. In Pakistan, the floods have destroyed a fifth of the country’s crops. Drought in Australia and floods in the Canadian prairies have reduced these countries’ grain production.
In response to the higher prices and fears of food riots spreading, the United Nations has called a special meeting on 24 September to bring food exporters and importers together to consider “appropriate reactions to the current market situation”. And yet, although global cereal production is down by some 5% on last year, it is still predicted to be the third largest harvest on record.
So what is causing the price rises? Is it simply a question of the balance of supply and demand and, if so, what has caused the relevant shifts in supply and/or demand? And what role does speculation play? The following articles look at the issues and at the outlook for commodity prices over the coming months.
Clearly changes in commodity prices affect the rate of inflation. The news item (Bank of England navigates choppy waters) amongst other issues looks at the outlook for inflation and the various factors influencing it.

Questions
- Use a supply and demand diagram to illustrate (a) what has been happening to wheat prices (b) what is likely to happen to wheat prices over the coming months?
- How relevant is the price elasticity of demand and supply and the income elasticity of demand to your analysis?
- What factors have caused the shifts in demand and/or supply of wheat and copper?
- What has been the role of speculation in the price rises? Is this role likely to change over the coming months?
- What is likely to happen to food prices in the shops over the coming months? Would you expect bread prices to rise by the same percentage as wheat? If so, why; if not, why not?
- If commodity prices generally rose by 5 per cent over the coming year, would you expect inflation to be 5 per cent? Again, if so, why; if not, why not?
If we are faced with simple and limited choices, we may make careful decisions based on a number of criteria: in other words, we will identify various characterisitics we are looking for and see how well the various alternative products or activities meet our criteria. When we have lots of choice, however, we may be less careful or get confused.
In this Guardian podcast, the panelists discuss complex choices between many products and/or characteristics. Are people being ‘rational’ when making such choices? Is being less careful simply a rational use of scarce time? Do people really want lots of choice or would they prefer more limited choice? Can experiments where people are given choices help us to understand how people choose and how much choice businesses or government should give people? Then there is the question of producers/suppliers of products. Does choice promote competition and product development and is there an optimum amount of choice to achieve this?

Every three years the Bank for International Settlements (the central bankers’ central bank) publishes a survey of foreign exchange market activity. The latest survey has just been published. Despite the banking crisis and subsequent recession, foreign exchange market turnover has increased by nearly 20% since 2007. The daily average value of currencies traded on the foreign exchange market is now $3.981 trillion. In 2007 it was $3.324 trillion and in 2001 it was just $1.239 trillion.
According to the BIS press release:
• The increase was driven by the 48% growth in turnover of spot transactions, which represent 37% of foreign exchange market turnover. Spot turnover rose to $1.5 trillion in April 2010 from $1.0 trillion in April 2007.
• The increase in turnover of other foreign exchange instruments was more modest at 7%, with average daily turnover of $2.5 trillion in April 2010. Turnover in outright forwards and currency swaps grew strongly. Turnover in foreign exchange swaps was flat relative to the previous survey, while trading in currency options decreased.
• As regards counterparties, the higher global foreign exchange market turnover is associated with the increased trading activity of “other financial institutions” – a category that includes non-reporting banks, hedge funds, pension funds, mutual funds, insurance companies and central banks, among others. Turnover by this category grew by 42%, increasing to $1.9 trillion in April 2010 from $1.3 trillion in April 2007. For the first time, activity of reporting dealers with other financial institutions surpassed inter-dealer transactions (i.e. transactions between reporting dealers).
• Foreign exchange market activity became more global, with cross-border transactions representing 65% of trading activity in April 2010, while local transactions account for 35%.
• The percentage share of the US dollar has continued its slow decline witnessed since the April 2001 survey, while the euro and the Japanese yen gained relative to April 2007. Among the 10 most actively traded currencies, the Australian and Canadian dollars both increased market share, while the pound sterling and the Swiss franc lost ground. The market share of emerging market currencies increased, with the biggest gains for the Turkish lira and the Korean won.
• The relative ranking of foreign exchange trading centres has changed slightly from the previous survey. Banks located in the United Kingdom accounted for 36.7%, against 34.6% in 2007, of all foreign exchange market turnover, followed by the United States (18%), Japan (6%), Singapore (5%), Switzerland (5%), Hong Kong SAR (5%) and Australia (4%).
The following articles look at some of the details of the report and consider their implications for London and for the global economy: an economy that has grown (in money terms) by 82% since 2001, while exports have grown by 101% and foreign currency transactions by 221%.
