Are consumers ‘rational’ is the sense of trying to maximise consumer surplus? In some circumstances the answer is yes. When we go shopping we do generally try to get best value for money, where value is defined in terms of utility. With limited incomes, we don’t want to waste money. If we were offered two baskets of goods costing the same amount, we would generally choose basket A if its contents gave us more utility than basket B.
So why do we frequently buy things that are bad for us? Take the case of food. Why do we consume junk food if we know fresh produce is better for us? To answer this we need to look a little closer at the concept of utility and what motivates us when we consumer things. The following article does just that. It reports on writings of Michael Pollan. Pollan looks at our motivation when choosing what and how much to eat. For much of the time our choices are governed by our subconscious and by habit.
“Millions of humans, while believing they govern their actions with conscious intelligence, clean every morsel from their dinner plates, mainly because their parents told them to. And we do this even if we don’t particularly like the food on the plate and even if we know we should be eating less of it. Unthinkingly, we follow a habit we would condemn if we looked at it clearly.”
You mar what you eat and the politics of Michael Pollan National Post (Canada), Robert Fulford (18/1/10)
Questions
- What is meant by ‘rational behaviour’? Is it reasonable to assume that people are rational in most circumstances?
- Is eating junk food consistent with the attempt to maximise consumer surplus?
- How relevant is the principle of diminishing marginal utility in explaining the amount of junk food we eat?
- To what extent are the problems that Pollan identifies examples of (a) imperfect information; (b) irrationality?
- What does people’s eating behaviour reveal about their preferences for the present over the future and hence their personal discount rate?
- What are the policy implications of Pollan’s analysis for governments trying to get people to eat more healthily?
The UK section of the North Sea used to be sufficient to supply all of the country’s gas requirements, but now some has to be imported from countries such as Norway. With the cold weather, the usage of gas has increased to record levels and there are now concerns for future supplies, especially if the cold weather returns.
However, the National Grid has said that there isn’t a problem, despite a glitch with a Norwegian gas supply. Gas supplies from various sources have been increased to deal with this record demand. There have been calls for Britain to build more gas storage facilities and the National Grid did issue ‘gas balancing alerts’, asking power firms and other large industries to cut back on their gas consumption. There are suggestions that even if supplies of gas aren’t a problem at the moment, we could see serious shortages in a few years.
Following growing demand for gas supplies, wholesale prices rose, but they did fall again when supplies were increased. Prices of household bills could be affected in the future, but for now, it’s too soon to tell. However, rising prices could spell further trouble for ours and other economies suffering from extreme weather on top of a financial crisis. Economic recovery could be put in jeopardy.
This fear of gas shortages and security of supply has led environmental and business groups to argue that Britain needs to diversify its energy supplies and become less dependent on foreign exports. This issue fits in with the latest developments in new investment in wind turbines.
Who knew that something as beautiful as snow could cause so much trouble and provide so much economic analysis!

Questions
- Illustrate the effects in the gas market of increasing demand and the resulting shortages. Then show the effects of increasing the supplies of gas. How is equilibrium achieved when there is a shortage in the market?
- Why did energy prices increase and then fall?
- To what extent should the government have been able to forecast this higher demand? Should better contingency plans have been in place?
- The article from CNN Money looks at the effect of rising prices of oil and energy and how this is likely to affect consumer spending. Why could rising prices of these commodities adversely affect economic recovery?
- What is an ‘interruptible contract’ and how useful have they been in dealing with these gas shortages?
- Why has this gas shortage presented environmental groups with an opportunity to promote renewable energy supplies? Think about economic interdependence.
- What alternatives are there to our current gas sources? Are they realistic alternatives?
You can hardly have failed to miss the snow! From children sledging to cars skidding and from being snowed in from work to being snowed in at work. In the UK, it only happens once in a while and when it does, life practically comes to a standstill. Why is this not the case in countries such as Norway? Well, one way of looking at it as that they’re used to it and have tried and tested methods of dealing with it and the investment to match. As we suffer from these severe conditions only once in a while, any significant investment in improving our ability to deal with it could be considered a waste of money.
However, many businesses affected by the snowy conditions will certainly not see it this way. Transport links have been disrupted: roads closed; trains stopped; airports closed; tunnels blocked and sports fields unplayable. The worst affected city centres have been deserted and retailers have subsequently suffered. Even if shoppers had made it to the shops, they may have found many of them closed, as staff struggled to make it in to work across the country. Office workers were being advised to work from home where possible and off-duty medical staff that could make it in to work were covering for those that couldn’t. Even emergency services were said to be going out only to life threatening situations.
Small businesses are suffering from declining sales, as deliveries cannot be made. Farmers too are facing major problems. Thousands of livestock are being frozen to death and many animals are without food, as farmers simply can’t get to them, suffering from snow drifts that have been up to 4 feet deep across Scotland. These are the worst conditions that some areas in Scotland have experienced in 50 years and they’re expected to continue for some time. Cattle farmers in the UK are also facing wasting thousands of litres of milk, as lorries find they cannot access the farms. This could simply mean pouring all this milk down the drain.
Estimates suggest that this cold winter could cost the UK economy £14.5bn in total from lost business. Daily costs will be about £690 million – certainly something that we don’t need in the current climate – financial that is! The following articles look at some of the problems faced across the UK. Read them and then think about the questions below.

Increasing traffic on the roads is observable by everyone and government policy is focused on reducing the demand for road space, rather than increasing its supply. One method has been to improve public transport and make it a viable substitute for car travel. Private costs of motoring have increased, but if there is no viable alternative, people will continue to demand car travel. Investment in buses and trains has improved their quality: they are more frequent, more reliable, arguably more comfortable and supposed to be part of an integrated transport policy. Local bus services provide a crucial link for local communities, but it is these services that are now facing problems.
In your economics lectures, you may have looked at local bus services, when you considered monopolies, oligopolies and possibly contestable markets. Oligopolies, whilst closer to the monopoly end of the market spectrum can be very competitive, but are also open to collusion and anti-competitive practices. The local bus sector has been referred to the Competition Commission by the Office of Fair Trading through complaints of ‘predatory tactics’ by companies. It is argued that local bus services, by limiting competition, are causing prices to rise and the quality of service to fall. One key issue is that those companies established in the market are alleged to be acting aggressively towards smaller bus companies and thus reducing competition in the industry. A low number of bids for supported service contracts in many areas, local bus routes dominated by a few large companies and predatory actions by incumbent firms are all complaints that this industry is facing.
This investigation is especially important, given the amount of public money that goes into the bus industry: £1.2bn. Investigations found that in areas of limited competition, prices were 9p higher. A number of take-overs have contributed to this situation. Two-thirds of bus services are controlled by only five operators. This limits competition in the market and hence is argued to be against public interest. Yet, industry representatives still argue that the market is competitive. Read the following articles and answer the questions about this issue. Was the OFT right to to initiate this investigation?

- What are the main aspects of UK competition policy?
- What is a concentration ratio and how does this apply to the bus industry?
- What predatory tactics are being used in the local bus industry and how do they affect competition, prices and quality?

- Traffic congestion is a major problem. Explain the economic theory behind government intervention in this area. Think about the effects of taxes; building more roads; investment in substitutes. Which is likely to be the most effective method?
Most businesses have suffered over the past year or so. Profits and sales have fallen, as the UK (and global) economy suffered from a recession that’s seen UK interest rates at 0.5%, unemployment rising and public debt at unprecedented levels. Christmas trading always sees a boost in sales and that’s just what’s happened for many businesses. Shoppers have responded to the doom and gloom of the past year by spending and making up for a hard year. Phrases such as “I decided to treat myself” became common on the news as reporters travelled to shopping centres across the UK. However, shops such as M&S and Next have warned that attempts by the government to reduce the public deficit could derail the consumer recovery.
These positive stories, whilst true, are a useful tool to help boost consumer confidence and keep expectations positive for the coming months. However, there are warnings that these figures shouldn’t be taken out of context. The economy is still in trouble and public debt has reached almost 60% of GDP. With cuts in government spending and rises in taxation expected, how much confidence should be taken from these positive signs in the retail sector? Only time will tell.

Questions
- Why are expectations important for the future of the British economy? Are the expectations rational or adaptive or a combination of the two?
- Are high Christmas sales really a sign that the economy is recovering? Discuss both sides of the argument. Will high sales now have an adverse effect on future trade in the UK?
- How will expected cuts in government spending affect sales in the retail sector?
- Tax rises are a possibility. How will this affect consumers and sales in the coming year? Think about the circular flow of income.
- If interest rates are increased in the coming months, trace through the likely effects in the goods market.
