The pound has fallen to its lowest rate against the euro since July 2013 and the lowest rate against the US dollar since 1985. Since August 2015, the pound has depreciated by 23.4% against the euro and 22.2% against the dollar. And since the referendum of 23 June, it has depreciated by 15.6% against the euro and 17.6% against the dollar.
On Sunday 2 October, at the start of the Conservative Party conference, the Prime Minister announced that Article 50, which triggers the Brexit process, would be invoked by the end of March 2017. Worries about what the terms of Brexit would look like put further pressure on the pound: the next day it fell by around 1% and the next day by a further 0.5%.
Then, on 6 October, it was reported that President Hollande was demanding tough Brexit negotiations and the pound dropped significantly further. By 7 October, it was trading at around €1.10 and $1.22. At airports, currency exchange agencies were offering less than €1 per £ (see picture).
With the government implying that Brexit might involve leaving the Single Market, the pound continued falling. On 12 October, the trade-weighted index reached its lowest level since the index was introduced in 1980: below its trough in the depth of the 2008 financial crisis and below the 1993 trough following Britain’s ejection from the European Exchange Rate Mechanism in September 1992.
So just why has the pound fallen so much, both before and after the Brexit vote? (Click here for a PowerPoint of the chart.) And what are the implications for the economy?
The articles explore the reasons for the depreciation. Central to these are the effects on the balance of payments from a possible decline in inward investment, lower interest rates leading to a net outflow of currency on the financial account, and stimulus measures, both fiscal and monetary, leading to higher imports.
Worries about the economy were occurring before the Brexit vote and this helped to push sterling down in late 2015 and early 2016, as you can see in the chart. This article from The Telegraph of 14 June 2016 explains why.
Despite the short-run effects on the UK economy of the Brexit vote not being as bad as some had predicted, worries remain about the longer-term effects. And these worries are compounded by uncertainty over the Brexit terms.
A lower sterling exchange rate reduces the foreign currency price of UK exports and increases the sterling price of imports. Depending on price elasticities of demand, this should improve the current account of the balance of payments.
These trade effects will help to boost the economy and go some way to countering the fall in investment as businesses, uncertain over the terms of Brexit, hold back on investment in the UK.

If you want a ticket for an event, such as a match or a concert, but the tickets are sold out, what do you do? Many will go to an agency operating in the ‘secondary market’. A secondary market is where items originally purchased new, such as tickets, company shares, cars or antiques, are put up for sale at a price that the market will bear.
The equilibrium price in a secondary market is where supply equals demand and the actual price will approximate to this equilibrium. In the case of tickets, this equilibrium price can be much higher than the original price sold by the venue or its agents. The reason is that the original price is below the equilibrium.
This is illustrated in the figure (click here for a PowerPoint). Assume that the total supply of tickets is Qs. Assume also that the official box office price is Pbo
and that demand is given by the demand curve D. At the box office price demand exceeds supply by Qd – Qs. There is thus a shortage, with many fans unable to obtain a ticket at the official price. Many of you will be familiar with having to be as quick as possible to get hold of tickets where demand considerably outstrips supply. Events such as Glastonbury sell out within seconds of coming on sale.
If you buy a ticket and then find out you cannot go to the event, you can sell the ticket on the secondary market through an online site or agency. Such agencies could be seen as providing a useful service as it means that otherwise empty seats will be filled. But if the equilibrium price is well above the original ticket price, there is the potential for huge gain by the agencies, who may pay the seller considerably less than the agency then sells the ticket to someone else.
What is more, the difference between the original price and the equilibrium price in the secondary market makes ticket touting, or ticket ‘scalping’, highly profitable. This is where people buy tickets with no intention of using them themselves but in order to sell them at much higher prices on the secondary market. Such ticket touting has been illegal for football matches since 1994 and was illegal for the 2012 London Olympics, but it is legal for plays, concerts, festivals and other events.
Ticket touts are often highly organised in obtaining tickets at official prices by buying early and using multiple credit cards and multiple identities to avoid systems that restrict the number of tickets issued to a card. They often use internet bots to mass purchase tickets the moment they go on sale.

Those in favour of ticket touting argue that the high price in the secondary market is just a reflection of demand and supply (see the IEA article below). Ticket touting allows tickets to be directed to people who value them most and will get the greatest benefit from it. What is more, banning ticket touting, so the argument goes, would simply drive it underground.
Those against argue on grounds of equity. Ticket prices set below the equilibrium are designed to give greater equality of access to fans. Rationing on a first-come first-served system, either on the internet or by a queue, is seen to be fairer than one by ability/willingness to pay. A poor person may be just as keen to go to an event as a rich person and gain just as much enjoyment from it, but cannot afford the high equilibrium price. What is more, non of the profit from the higher prices reaches the event organisers or the artists or players. Yet the mark-up and hence profit made by ticket touts can be massive, as the first Observer article below shows.
Various measures are being tried to prevent ticket touting. One is the use of paperless tickets, with the number of tickets limited per person and with people having to show their ticket on their phones along with ID at the door or gate. If a person cannot attend, then the solution is a system where they can give the ticket back to the box office (perhaps electronically) which will re-sell it for them at the official price.
A government-backed investigation, the Waterson review reported in May 2016 and recommended that touts should be licensed and that there should be harsher penalties for firms that flout consumer rights law as applying to ticket sales. Whether this would be sufficient to bring secondary market prices down significantly, remains to be seen. In the meantime, organisers do seem to be trying to find ways of beating the touts through smarter means of selling.

Questions
- Why can ticket touts sell tickets above the equilibrium price shown in the diagram?
- In what ways could ticket touts be said to be distorting the market?
- How do ticket touts reduce consumer surplus? Could they reduce it to zero?
- Why may allowing ticket touting to take place result in empty seats at concerts or other events?
- Would it be a good idea for event organisers to charge higher prices for popular events than they do at present, but still below the equilibrium
- How does the price elasticity of demand influence the mark-up that ticket touts can make? Illustrate this on a diagram similar to the one above.
- Is it in ticket touts’ interests to adjust prices as an event draws closer, just as budget airlines adjust seat prices as the plane fills up? Could organisers sell tickets in the primary market in this way with prices rising as the event fills up?
- Discuss the various ways in which the secondary ticket market could be reformed? To what extent do these involve reforms in the primary ticket market?
Your Americano, Latte or Cappuccino may soon be more expensive. This is because coffee bean prices are rising. A combination of continuing growth in demand and poor coffee harvests in various parts of the world have led to a rise in both Arabica and Robusta prices, with the International Coffee Organization’s Composite Indicator price (in US dollars) having risen by over 30% since mid-January this year (see chart below: click here for a PowerPoint)
Supply has been affected by droughts in Brazil and Vietnam, two of the world’s biggest coffee producers, and by pests (the Coffee Berry Borer) in the Kilimanjaro region of Tanzania and in other East African countries. Global exports of coffee in July 2016 were 22% down on the same month in 2015.
The growing shortage and rising current (spot) prices is reflected in future prices.
These are prices determined in the market now for trading at a specified future date (e.g. in three months’ time). Future prices depend on predictions of the balance of demand and supply in the future. According to the MarketWatch article below, “Analysts at Société Générale in a note predicted that prices could climb about 30% further by the end of next year”. The current (mid-September) spot price of robusta coffee beans is around $0.96 per lb. The December 2016 future price is around $1.48.
So what effect will this have on the prices in Starbucks, Costa or Caffè Nero? And what effect will it have on ground or instant coffee in supermarkets? To quote the MarketWatch article again:
A research report from the US Department of Agriculture found that, on average, a 10% increase in green-coffee-bean prices per pound would yield a 2% increase in both manufacturer prices and at the register in places like Starbucks Corp.
This is because the cost of coffee beans is just one element in the costs of coffee roasters and coffee shops. Also these companies use futures markets to smooth out the prices they pay. They hold stockpiles of coffee, which they build up when prices are low and draw on when prices are high. This helps to reduce fluctuations in retail prices.
So don’t worry too much about the price of your morning coffee – at least, not yet.

Behavioural economists study how people’s buying, selling and other behaviour responds to various incentives and social situations. They don’t accept the simplistic notion that people are always rational maximisers. As the Livemint article below states, “According to behavioural economists, the human brain neither has the time nor the ability to process all the information involved in decision making, as assumed by the rational model.” Instead, rationality is bounded: people use simple rules of thumb in making decisions – rules they have developed over time in the light of experience.
So can people’s behaviour be altered by understanding their limited rationality? Advertisers are only too well aware of a number of psychological ‘tricks’ to change people’s purchasing behaviour. For example, wanting to be approved of by your friends is used by advertisers to sell various fashion products and toiletries. Often, people need only a relatively small ‘nudge’ to change the way they behave.
And it is not just advertisers who are using the insights of behavioural economics. Governments are increasingly trying to find ways of nudging people to behave in ways that are better for themselves or for society.

In 2010, David Cameron set up a ‘Nudge Unit’, formally know as ‘The Behavioural Insights Team‘. It has produced a number of academic papers on topics as diverse as tax compliance, incentives for university attendance, charitable giving in the workplace and using SMS reminders to reduce missed hospital appointments. The academic evidence can then be use as the basis for policy.
Another nudge unit has been set up in Australia (see second article below). The USA, Singapore and various other countries are increasingly using the insights of behavioural economics to devise policy to affect human behaviour.
Two recent pieces of work by the UK team concern ways of discouraging doctors from over-prescribing antibiotics and using encouraging text messages to FE students to reduce dropout rates. Another nudge has been used by the tax authorities (HMRC) who have been sending out texts to remind people to pay their taxes on time and to make them aware that they are being monitored. The message read, “Most people pay on time to avoid penalties”.
The articles below look at these recent initiatives and how human behaviour can be changed in a relatively low-cost way. In most cases this involves a simple nudge.

Questions
- Explain what is meant by bounded rationality.
- Give some examples from your own behaviour of decisions made using rules of thumb.
- Should we abandon models based on the assumption of rational maximising behaviour (e.g. attempts to maximise consumer surplus or to maximise profit)?
- Find out some other examples of how people might be nudged to behave in ways that are in their own interest or that of society.
- How might people be nudged to eat more healthily or to give up smoking?
- To what extent can financial incentives, such as taxes, fines, grants or subsidies be regarded nudging? Explain.
- Why, do you think, the message by an Australian hospital, “if you attend, the hospital will not lose the $125 we lose when a patient does not turn up” was successful in reducing missed appointments by 20%, while the message, “if you do not attend, the hospital loses $125” was not as effective?
The UK government has finally given the go-ahead to build the new Hinkley C nuclear power station in Somerset. It will consist of two European pressurised reactors, a relatively new technology. No EPR plant has yet been completed, with the one in the most advanced stages of construction at Flamanville in France, having experienced many safety and construction problems. This is currently expected to be more than three times over budget and at least six years behind its original completion date of 2012.
The Hinkley C power station, first proposed in 2007, is currently estimated to cost £18 billion. This cost will be borne entirely by its builder, EDF, the French 85% state-owned company, and its Chinese partner, CGN. When up and running – currently estimated at 2025 – it is expected to produce around 7% of the UK’s electricity output.
On becoming Prime Minister in July 2016, Theresa May announced that the approval for the plant would be put on hold while further investigation of its costs, benefits,
security concerns, technological issues and safeguards was conducted. This has now been completed and approval has been granted subject to new conditions. The main one is that the government “will be able to prevent the sale of EDF’s controlling stake prior to the completion of construction”. This will allow the government to prevent change of ownership during the construction phase. Thus, for example, EDF, would not be allowed to sell its share of Hinkley C to CGN, which currently has a one-third share in the project. EDF and CGN have accepted the new terms.
After Hinkley the government will have a ‘golden share’ in all future nuclear projects. “This will ensure that significant stakes cannot be sold without the Government’s knowledge or consent.”
In return for their full financing of the project, the government has guaranteed EDF and CGN a price of £92.50 per megawatt hour of electricity (in 2012 prices). This price will be borne by consumers. It will rise with inflation from now and over the first 35 years of the power station’s operation. It is expected that the Hinkley C will have a life of 60 years.
Critics point out that this guaranteed ‘strike price’ is more than double the current wholesale price of electricity and, with the price of renewables falling as technology improves, it will be an expensive way to meet the UK’s electricity needs and cut carbon emissions.
Those in favour argue that it is impossible to predict electricity prices into the distant future and that the certainty this plant will give is worth the high price by current standards.

To assess the desirability of the plant requires an assessment of its costs and benefits. In principle, this is a relatively simple process of identifying and measuring the costs and benefits, including external costs and benefits; discounting future costs and benefits to give them a present value; weighting them by their probability of occurrence; then calculating whether the net present value is positive or negative. A sensitivity analysis could also be conducted to show just how sensitive the net present value would be to changes in the value of specific costs or benefits.
In practice the process is far from simple – largely because of the huge uncertainty over specific costs and benefits. These include future wholesale electricity prices, unforeseen problems in construction and operation, and a range of political issues, such as pressure from various interest groups, and attitudes and actions of EDF and CGN and their respective governments, which will affect not only Hinkley C but other future power stations.
The articles look at the costs and benefits of this, the most expensive construction project ever in the UK, and possibly on Earth..
