The Prudential Regulation Authority is the new UK authority in charge of banking regulation and is part of the Bank of England. In a report published on 20/6/13, the PRA found that UK banks had a capital shortfall of £27.1 billion (see Chart 1 below for details) if they were to meet the 7% common equity tier 1 (CET1) ratio: one of the capital adequacy ratios (CARs) specified under the Basel III rules (see Rebuilding UK banks: not easy to do and Chart 2 below).

CET1 includes bank reserves and ordinary share capital (‘equities’). To derive the CET1 ratio, CET1 is expressed as a percentage of risk-weighted assets. As Economics for Business (6th ed) page 467 states:

Risk-weighted assets are the total value of assets, where each type of asset is multiplied by a risk factor. …Cash and government bonds have a risk factor of zero and are thus not included. Inter-bank lending between the major banks has a risk factor of 0.2 and is thus included at only 20 per cent of its value; residential mortgages have a risk factor of 0.35; personal loans, credit-card debt and overdrafts have a risk factor of 1; loans to companies carry a risk factor of 0.2, 0.5, 1 or 1.5, depending on the credit rating of the company. Thus the greater the average risk factor of a bank’s assets, the greater will be the value of its risk weighted assets, and the lower will be its CAR.

The data published by the PRA, based on end-2012 figures, show that the RBS group is responsible for around 50% of the capital shortfall, the Lloyds Banking Group around 32%, Barclays around 11%, the Co-operative around 5.5% and Nationwide the remaining 1.5%. HSBC, Santander and Standard Chartered met the 7% requirement. The PRA found that banks already were taking measures to raise £13.7bn, but this still leaves them requiring an additional £13.4 for current levels of lending.

So what can the banks do? They must either raise additional capital (the numerator in the CAR) or reduce their risk-weighted assets (the denominator). Banks hope to be able to raise additional capital. For example, Lloyds is planning to sell government securities and US mortgage-backed securities and hopes to have a CET1 ratio of around 10% by the end of 2013. Generally, the banks aim to raise the required level of capital through income generation, the sale of assets and restructuring, rather than from issuing new shares.

What both the Bank of England and the government hope is that banks do not respond by reducing lending. While that might enable them to meet the 7% ratio, it would have an undesirable dampening effect on the economy – just at a time when it is hoped that the economy is starting to recover. As Robert Peston states:

I understand that both Barclays and Nationwide feel a bit miffed about being forced to hit this tough so-called leverage ratio at this juncture, because they are rare in that they have been supporting economic recovery by increasing their net lending.

They now feel they are being penalised for doing what the government wants. So I would expect there to be something of a spat between government and regulators about all this.

Every summer a number of air shows take place in the UK, such as those at Farnborough, Cosford and the Royal International Air Tattoo. Some of these events prove to be extremely popular and successful. For example, over 50,000 people attended the event at Cosford on Sunday 9th June to watch a five-and-a-half-hour flying display, including the Red Arrows, a Vulcan bomber and a RAF Battle of Britain Memorial Flight, which featured Spitfire, Hurricane and Lancaster aircrafts.

The event was so popular that some people who had paid £25 for a ticket failed to make it to the show ground because they were stuck in a 9 mile traffic jam! The popularity of these events does raise an interesting economic question. Why do so many people pay to attend when it is possible to watch much of the air show from outside the showground? If people can enjoy the benefits of watching an event whether or not they have paid then we might expect the majority of them not to pay.

Air shows seem to have some of the characteristics of a public good: i.e. to some extent the consumption benefits are both non-rival and non-excludable. By non-rival it is meant that one person’s use or consumption of the good does not decrease the quantity available for somebody else to use or consume. If one person watches the Red Arrows fly by, it does not decrease the ability of others to watch them. Contrast this with a product that has the characteristic of being ‘rival’ such as a hamburger. If someone eats a hamburger, it reduces the amount that is available for others to enjoy. The good is ‘used up’ during consumption. Other people cannot eat the same hamburger!!! Many sporting and music events share this characteristic of non-rivalry. For example if somebody is watching a band playing live at Glastonbury it does not stop somebody else from enjoying the benefits of watching the band. The performance of the band is not ‘used up’ like the hamburger when a person watches the show.

The major difference between Glastonbury and an air show is that the event organisers at Glastonbury can prevent people who have not paid for a ticket from enjoying the show. The event is excludable, as fans have to enter the show arena in order to see the bands. However, as one contributor to an internet discussion site commented:

Air show organisers are at a particular disadvantage compared to other show organisers because the key elements of their show can be seen for miles.

Another contributor added that:

Unfortunately being an air show by its very nature it’s very public – the planes are in the air for everyone to see for free for miles around.

In other words, air shows have the characteristic of being non-excludable, as people can benefit regardless of whether they have paid or not.

These public good properties seem to be causing problems for an air show in Welshpool that appears to have an issue with a number of non-payers watching the event. The organisers recently stated that:

We can’t stop people watching from the hillsides, but perhaps we can make them understand that they need to come to the show and pay.

The previous year the organisers had sent people out with buckets to collect voluntary donations from those sitting on the hillside. However they found that:

People were not for giving much at all and it was noticeable how much copper was in the buckets we’d used and there were hardly any notes.

One solution being proposed in order to generate more revenue is to increase the entry fee, which is currently £5, in order to compensate for those who are not paying.

Questions

  1. What practical problems does a show such as Glastonbury face in trying to make the event excludable?
  2. In the blog it explains how one person watching a band live does not have a negative impact on the pleasure other people will derive from watching the same band: i.e. it is non-rival. Is this always true? Can you think of any circumstances when watching a live band might become a rival good?
  3. What term do economists use for goods that are non-rival but are excludable? Think of at least three examples.
  4. What ideas might the organisers of an air show adopt to encourage people to pay and enter the show ground area?
  5. Can you think of any strategies that might be used to increase the number and size of the voluntary donations made by those who watch the airshow for free from a hill-side?
  6. What are the organisers assuming about the price elasticity of demand for the air show at its current price if they claim that increasing prices will lead to an increase in revenue?

Since the beginning of 2009, central banks around the world have operated an extremely loose monetary policy. Their interest rates have been close to zero (click here for a PowerPoint of the chart) and more than $20 trillion of extra money has been injected into the world economy through various programmes of quantitative easing.

The most recent example of loose monetary policy has been in Japan, where substantial quantitative easing has been the first of Japan’s three arrows to revive the economy (the other two being fiscal policy and supply-side policy).

One consequence of a rise in money supply has been the purchase of a range of financial assets, including shares, bonds and commodities. As a result, despite the sluggish or negative growth in most developed countries, stock markets have soared (see chart). From March 2009 to May 2013, the FTSE 100 rose by 91% and both the USA’s Dow Jones Industrial average and Germany’s DAX rose by 129%. Japan’s NIKKEI 225, while changing little from 2009 to 2012, rose by 78% from November 2012 to May 2013 (click here for a PowerPoint of the chart).

The US economy has been showing stronger growth in recent months and, as a result, the Fed has indicated that it may soon have to begin tightening monetary policy. It is not doing so yet, nor are other central banks, but the concern that this may happen in the medium term has been enough to persuade many investors that stock markets are likely to fall as money eventually becomes tighter. Given the high degree of speculation on stock markets, this has led to a large-scale selling of shares as investors try to ‘get ahead of the curve’.

From mid-May to mid-June, the FTSE 100 fell by 6.2%, the Dow Jones by 2.6%, the DAX by 4.5% and the NIKKEI by 15%. In some developing countries, the falls have been steeper as the cheap money that entered their economies in search of higher returns has been leaving. The falls in their stock markets have been accompanied by falls in their exchange rates.

The core of the problem is that most of the extra money that was created by central banks has been used for asset purchase, rather than in financing extra consumer expenditure or capital investment. If money is tightened, it is possible that not only will stock and bond markets fall, but the fragile recovery may be stifled. In other words, tighter money and higher interest rates may indeed affect the real economy, even though loose monetary policy and record low interest rates had only a very modest effect on the real economy.

This poses a very difficult question for central banks. If even the possibility of monetary tightening some time in the future has spooked markets and may rebound on the real economy, does that compel central banks to maintain their loose policy? If it does, will this create an even bigger adjustment problem in the future? Or could there be a ‘soft landing’, whereby real growth absorbs the extra money and gradually eases the inflationary pressure on asset markets?

The UK electricity supply market is an oligopoly. Over 95% of the market is supplied by the ‘big six’: British Gas (Centrica), EDF Energy, E.ON, npower (RWE), Scottish Power (Iberdrola) and SSE. The big six also generate much of the electricity they supply; they are vertically integrated companies. Between them they generate nearly 80% of the country’s electricity. There are a further two large generators, Drax Power Limited and GDF Suez Energy UK, making the generation industry an oligopoly of eight key players.

Ofgem, the energy market regulator, has just published a report on the wholesale electricity market, arguing that it is insufficiently liquid. This, argues the report, acts as a barrier to entry to competitor suppliers. It thus proposes measures to increase liquidity and thereby increase effective competition. Liquidity, according to the report, is:

… the ability to quickly buy or sell a commodity without causing a significant change in its price and without incurring significant transaction costs. It is a key feature of a well-functioning market. A liquid market can also be thought of as a ‘deep’ market where there are a number of prices quoted at which firms are prepared to trade a product. This gives firms confidence that they can trade when needed and will not move the price substantially when they do so.

A liquid wholesale electricity market ensures that electricity products are available to trade, and that their prices are robust. These products and price signals are important for electricity generators and suppliers, who need to trade to manage their risks. Liquidity in the wholesale electricity mark et therefore supports competition in generation and supply, which has benefits for consumers in terms of downward pressure on bills, better service and greater choice.

So how can liquidity be increased? Ofgem is proposing that the big six publish prices for two years ahead at which they are contracting to purchase electricity from generators in long-term contracts. These bilateral deals with generators are often with their own company’s generating arm. Publishing prices in this way will allow smaller suppliers to be able to seek out market opportunities. The generating companies will not be allowed to refuse to contract to supply smaller companies at the prices they are being forced to publish.

In addition, Ofgem is proposing that generators would have to sell 20% of output in the open market instead of through bilateral deals. As it is, however, some 30% of output is currently auctioned on the wholesale spot market (i.e. the market for immediate use).

But it is pricing transparency plus small suppliers being able to gain access to longer-term contracts that are the two key elements of the proposed reform.

How important are emotions when you go shopping? Many people go shopping when they ‘need’ to buy something, whether it be a new outfit, food/drink, a new DVD release, a gift, etc. Others, of course, simply go window shopping, often with no intention of buying. However, everyone at some point has made a so-called ‘impulse’ purchase.

There is only one article below, which is from the BBC and draws on data released from the National Employment Savings Trust’s survey. This report suggests that British people spend over £1 billion every year on impulse buys – purchases that are not needed, were not intended and are often regretted once the ‘high’ has worn off. Often, it is the way in which a product is advertised or positioned that leads to a spontaneous purchase – seeing chocolate bars/sweets at the tills; a product offered at a huge discount advertised in the window of a shop; 2 for 1 purchases; points for loyalty etc. All of these and more are simple techniques used by retailers to encourage the impulse buy. As consumer psychologist, Dr. James Intriligator says:

Retailers have clever ways of manipulating customers to spend more but if you stick to your plans you can avoid being affected by their tactics.

In other cases, it’s simply the frame of mind of the consumer that can lead to such purchases, such as being hungry when you’re food shopping or having an event to attend the next day and deciding to go window shopping, despite already having something to wear! Dr. Intriligator continues, saying:

Your ability to resist and make rational choices is diminished when your glucose levels are down … When you get irrational, you fall back on trusted brands, which often leads you to spend more money … Later in the shop, you’re more tired and less likely to resist [impulse buys]

But are such purchases irrational? One of the key assumptions made by economists (at least in traditional economics) is that consumers are rational. This implies that consumers weigh up marginal costs and benefits when making a decision, such as deciding whether or not to purchase a product. But, do impulse buys move away from this rational consumer approach? Is buying something because it makes you happy in the short term a rational decision? Behavioural economics is a relatively new ‘branch’ of economics that takes a closer look at the decisions of consumers and what’s behind their behaviour. The following article from the BBC considers the impulse buy and leaves you to consider the question of irrational consumers.
