The history of macroeconomic thought has been one of lively debate between different schools.
First there is debate between those who favour active government intervention (Keynesians) to manage aggregate demand and those who favour a rules-based approach of targeting some variable, such as the money supply (as advocated by monetarists) or the rate of inflation (as pursued by many central banks), or a hybrid rule, such as a Taylor rule that takes into account a weighted target of inflation and real output growth.
Second there is debate about the relative effectiveness of monetary and fiscal policy. Monetarists argue that monetary policy is relatively effective in determining aggregate demand, which in turn affects output in the short run but only prices in the long run. Keynesians argue that monetary policy can be weak in the short run if the economy is in recession. Quantitative easing may simply be accompanied by a decline in the velocity of circulation. It’s not enough to make more money available and keep interest rates close to zero; people must have the confidence to borrow and spend. Keynesians argue that in these circumstances fiscal policy is more effective.
Third there is the debate about the size of the state and the extent of government borrowing. Libertarians, following the views of economists such as Hayek, argue that reducing the size of the state and reducing government borrowing will create a more dynamic economy, where the private sector will expand to take up the slack created by a reduction in the size of the public sector. Their approach to policy involves a mixture of cutting deficits and market-orientated supply-side policy. Economists on the left, by contrast, argue that economic growth is best stimulated in the short term by increases in government spending and that supply-side policy needs to be interventionist, with the government investing in infrastructure, research and development, education and health. Such growth policies, they argue can be targeted on the poor and help to arrest the growing inequality in society.
These debates have been given added impetus by the global financial crisis in 2008 and the subsequent recession, slow recovery and possibility of a slide back into recession. The initial response of governments and central banks was to stimulate aggregate demand. Through combinations of expansionary fiscal policy, interest rates cut to virtually zero and programmes of quantitative easing, the world seemed set on a course for recovery. But one result of the policies was a massive expansion in government deficits and debt. This led to increasing criticisms from the right, and a move away from expansionary to austerity fiscal policies in order to contain debts that were increasingly being seen as unsustainable. And all the while the debates have raged.
The following podcast and articles look at the debates and how they have evolved. The picture painted is a more subtle and nuanced one than a stark ‘Keynes versus Hayek’, or ‘Keynesians versus monetarists’.

Original post (19/9/11)
The Independent Commission on Banking (ICB), led by Sir John Vickers, has just delivered its report. Central to its remit was to investigate ways of making retail banking safer and avoid another bailout by the government, as was necessary in 2007/8.
The report recommended the ‘ringfencing’ of retail banking from the more risky investment banking, often dubbed ‘casino banking’. In other words, if the investment arm of a universal bank made a loss, or even faced collapse, this would not affect the retail arm. The ringfenced operations would include banking services to households and small businesses. Wholesale and investment banking would be outside the ringfence. As far as retail banking services to big business are concerned, these could be inside the ringfence, but details would need to be worked out about precisely which banking services to big business would be inside and which would be outside the ringfence.
The ICB was keen to stress that the ringfence should be high and that the retail arm should be both operationally and legally separate from the wholesale/investment arm. The ringfenced part of the bank should have a capital adequacy ratio of up to 20% (above the Basel III recommendations), with at least 10% of liabilities in the form of equity. Capital could only be moved from the ringfenced arm to the investment arm of the bank if this did not breach the 10% ratio.
The ICB report also recommends measures to increase competition in banking, including making it easier to switch accounts, greater transparency about the terms of accounts and a referral of the banking industry for a competition investigation in 2015. The cost to the banking industry of the measures, if fully implemented, is estimated to be between £4m and £7m.
Because of the requirement in the report for banks to build up their capital and the danger that a too rapid process here would jeopardise the expansion of lending necessary to underpin the recovery, banks would be given until 2019 to complete the recommendations. Moves towards this, however, would need to start soon.
Update (19/12/11)
In December 2011, the government announced that it would accept most of the ICB report, including separating retail and investment banking. It would not, however, demand such stringent capital requirements as those recommended in the report.
The following articles examine the details of the proposals and their likely effectiveness. The later articles examine the government’s response.

Questions
- Explain the difference between a capital adequacy ratio and a liquidity ratio. Will the Vickers proposals help to increase the liquidity of the retail banking arm of universal banks?
- Does it matter if equity capital in excess of the 10% requirement for retail banking is transferred to a bank’s investment arm?
- What risks are there for a bank in retail banking?
- What are the advantages and disadvantages of bringing in the measures gradually over an 8-year period?
- Does it matter that the capital adequacy requirements are higher than under the internationally accepted standards in Basel III?
- Assume that there is another global financial crisis. Will the proposals in the report mean that the UK taxpayer will not have to provide a bailout?
When people shop in supermarkets they often look for what’s on special offer. After all, everyone likes a bargain. About 35–37% of supermarket items are on special offer at any one time and around 50% of the money spent by customers is on such items.
But things aren’t always as they seem. Supermarkets use clever marketing to persuade people that they’re getting a good deal, while sometimes it’s nothing of the sort. Examples include putting up prices for a while and then reducing them again saying “huge reduction”; or promoting an offer of, say, “three for £2”, when you could buy an individual item for 60p; or using the word “now” £2.50 to imply that the previous price was higher, when in fact it wasn’t; or selling a double-sized “value pack” for more than double the price of the regular size. These tricks are commonplace in supermarkets.
Sometimes the wary consumer will be able to find out which offers are genuine, but it’s not always that easy. And even if you do buy something at a genuine discount, is it something you really want? Or have you been persuaded to buy it simply because it’s on offer? Supermarkets study consumers’ psychology. They find clever ways of promoting products to make us feel that we have done well in getting a bargain.
The following programme in the BBC’s Panorama series looks at the big four supermarkets in the UK – Tesco, Asda, Sainsbury’s and Morrisons – which between then have 68% of supermarket sales. It gives examples of some of the not so special offers and how consumers are being hoodwinked.

Questions
- What types of misleading offers are identified in the Panorama report?
- For what reasons are consumers “taken in” by such offers? Does this imply that consumers are irrational?
- Does intense oligopolistic competition between the big four supermarkets lead to lower prices?
- How is it possible for two supermarkets to claim that they are cheaper than the other? How would you decide which supermarket was generally cheaper?
- Why might it be difficult for an independent agency to do a comparison of prices of different supermarket chains?
Divided we stand is the title of a new report by the Organisation for Economic Co-operation and Development (OECD). Its sub-title is “Why inequality keeps rising”. The report shows how the gulf between rich and poor has widened in most countries, both developed and developing. As the introduction states:
In the three decades prior to the recent economic downturn, wage gaps widened and household income inequality increased in a large majority of OECD countries. This occurred even when countries were going through a period of sustained economic and employment growth.
The report analyses the major underlying forces behind these developments. Its conclusion is that inequality looks set to continue widening, especially with the worldwide economic slowdown and rise in unemployment. However, the report says that “there is nothing inevitable about growing inequalities. Globalisation and technological changes offer opportunities but also raise challenges that can be tackled with effective and well-targeted policies.”
So just what is the extent of inequality? How has it changed over time? And what can be done to reduce inequality? The webcast produced by the OECD to accompany the report looks at the problem, and the report and articles look at what can be done about it.

Questions
- Why may inequality be seen as a ‘bad thing’ for society as a whole and not just the poor?
- Does it matter for the poor if rich people’s incomes grow at a greater rate than those of the poor so long as the incomes of the poor do indeed grow?
- Explain what is meant by the Gini coefficient. What has happened to the Gini coefficient over the past few years across the world?
- Are there any common explanatory features in the economies of those countries where income inequality is growing rapidly? Similarly, are there any common explanatory features in the economies of those countries where income inequality is not growing, or growing only very slowly?
- What are the causes of rising inequality?
- Identify policies that can be adopted to tackle growing inequality.
- What problems arise from policies to reduce inequality by (a) reducing inequalities in disposable income; (b) providing more free services to all, such as healthcare and education? How might these problems be mitigated?
You’ve probably heard of Groupon. If you join its emailing list, the company will send you daily details of deals in your area that it has negotiated with local retailers. If you want to take advantage of any particular deal, you sign up for it online and if enough people do so to reach a minimum number agreed with the retailer, Groupon will bill your credit card. You then download the voucher and use it to purchase you discounted item or service. Discounts are often substantial – 50% or more.
But are these deals as good as they seem? On 2 December, the UK’s Advertising Standards Authority took the decision to refer Groupon UK to the Office of Fair Trading, following 48 breaches of the advertising code of practice in eleven months. It referred complaints about Groupon’s:
• Failure to conduct promotions fairly, such as not making clear significant terms and conditions
• Failure to provide evidence that offers are available
• Exaggeration of savings claims
And it was not just consumers who had complained. Many retailers found that so many people signed up for certain deals and the discounts were so great, with Groupon often charging the retailer half the discounted price, that retailers made substantial losses on the deals. One example was a cupcake maker, Rachel Brown, who runs the Need a Cake bakery in Reading, Berkshire. She had to bake so many extra cupcakes below cost that profits for the year were wiped out.
So what is the nature of this market failure and how appropriate are the competition authorities for dealing with it? The following webcasts and articles look at the issues. They also consider the growing problems Groupon faces in the market from new competitors.
It has not been good news recently for Groupon and it’s hardly surprising that, following Groupon’s flotation on the Nasdaq stock exchange in the USA last month, and an initial surge in the share price, its shares have since fallen by over 40%.
