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’.

In many parts of the UK, bus services are run by a single operator. In other parts, it is little different, with the main operator facing competition on only a very limited number of routes. Over the whole of England, Scotland and Wales there are 1245 bus operators, but the ‘big five’ (Arriva, FirstGroup, Go-Ahead, National Express and Stagecoach) carry some 70% of passengers. Generally these five companies do not compete with each other, but, instead, operate as monopolies, or near monopolies, in their own specific areas. On average, the largest operator in an urban area runs 69% of local bus services.
Given this lack of competition and potential abuse of monopoly power, the Office of Fair Trading referred local bus services in Great Briatin (excluding London) to the Competition Commission (CC) in January 2010. The CC has just published its final report. Paragraph 5 of the summary to the report states:
We concluded that there were four features of local bus markets which mean that effective head-to-head competition is uncommon and which limit the effectiveness of potential competition and new entry. These features are the existence of: high levels of concentration; barriers to entry and expansion; customer conduct in deciding which bus to catch; and operator conduct by which operators avoid competing with other operators in ‘Core Territories’ (certain parts of an operator’s network which it regards as its ‘own’ territory) leading to geographic market segregation.
And paragraph 8 states:
We decided on a package of remedies with three main elements to address the AECs [adverse effects on competition] that we found. First, the remedies include market-opening measures to reduce barriers to entry and expansion, thereby reducing market concentration and providing an environment in which competition is likely to be sustained. By reducing barriers to entry and expansion, we also expect it to become harder for operators to sustain a coordinated outcome. Second, the remedies include measures to promote competition in relation to the tendering of contracts for supported services. Third, we made recommendations about the wider policy and regulatory environment, including emphasizing compliance with and effective enforcement of competition law.
The following articles look at the findings of the report and at the potential for improving the service to passengers, in terms of quality, frequency and price.

- In what circumstances are local bus services a natural monopoly? Is this generally the case?
- In a non-regulated bus market, how could established operators use predatory pricing to drive out new entrants?
- How may offering reductions for return tickets reduce competition on routes where there is a large operator and one or more smaller ones?
- What practices can established large operators use to drive out smaller competitors?
- Go through the four reasons given by the CC why head-to-head competition in local bus markets is uncommon and in each case consider what remedies could be adopted by the regulator or by local authorities.
- Which of the remedies proposed by the CC involve encouraging more competition and which involve tighter regulation?

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?
The European Central Bank does not provide direct support to eurozone countries by buying new bonds. However, it can give indirect support by helping banks buy such bonds. In a move announced on 8 December, the ECB will increase the maximum term of its ‘longer-term refinancing operations’ (LTROs) from the current 13 months to three years. In other words, it will effectively provide three-year loans to banks by purchasing banks’ assets on a ‘repurchase (repo)’ basis, whereby banks agree to buy back the assets at the end of the three-year term.
The hope is that banks will use these loans (at an annual rate of 1%) to purchase new bonds from countries such as Italy and Spain. If banks are more willing to buy them, this should help reduce the interest rate at which governments are forced to borrow. Banks would benefit from the ‘carry trade’, whereby they borrow at a low interest rate (from the ECB) and lend at a higher rate to governments by buying their bonds.
To encourage banks to take advantage of these new longer-term repos,the ECB announced that the assets it was prepared to purchase would include securitised assets with a rating of single A (the highest rating is AAA). In other words, it would accept assets with a ‘second-best rating’.
But although the scheme would allow banks to make a clear gain from a carry trade, banks may be reluctant to use such loans to increase their holdings of sovereign debt of countries with large debt to GDP ratios, given concerns in the market about the riskiness of such assets.

In Gloomy prospects for UK consumer spending in 2012? we talked about how consumer spending can be affected by the financial position of households. Figures from United Kingdom National Accounts – Blue Book 2011 (see Tables 6.1.9 and 10.10) give the latest complete set of balance sheets for the UK household sector. The figures are for 2010 and in this blog we provide a brief overview of what these figures reveal.
In effect, there are two main balance sheets of interest for households (and non-profit institutions serving households (NPISHs), i.e. charities and voluntary organisations). The first details their net financial wealth and the second their physical wealth, also known as their non-financial wealth. We begin with net financial wealth. This is found by subtracting financial liabilities (debt) from financial assets. The household sector in 2010 had financial liabilities of £1.54 trillion equivalent to 1.6 times its disposable income for the year or 1.1 times the nation’s Gross Domestic Product. Of these liabilities, £1.2 trillion was mortgage debt, i.e. loans secured against property. On the other hand, the sector had financial assets of £4.3 trillion equivalent to 4.4 times its disposable income in 2010 or 3 times GDP. Of these financial assets, the value in pension funds and life assurance was £2.27 trillion.
The net financial wealth of households and NPISHs in 2010 was £2.8 trillion, 2.9 times the sector’s disposable income for the year or 1.9 times GDP. To this we need to add physical wealth of £4.9 trillion, a massive 5 times the sector’s disposable income or 3.3 times the nation’s GDP. The majority of this is residential buildings the value of which were put at £4 billion for 2010. This demonstrates the significance of housing to the UK household sector balance sheet.
If we now add physical wealth to net financial wealth, we find that in 2010 the household and NPISH sector had a net worth of £7.7 trillion. To put this in context, it is equivalent to 7.8 times the disposable income it earned in 2010 and 5.3 times the UK’s Gross Domestic Product. While these are enormous figures it is worth noting that in 2007 the sector’s net worth was £7.4 trillion, equivalent to 8.5 times annual disposable income.
A trawl through the figures clearly shows the impact of the financial crisis on the sector’s net worth. From £7.4 trillion in 2007, net worth fell in 2008 to £6.6 trillion or 7.2 times annual disposable income. However, 2009 and 2010 did see the households’ net worth increase again – including relative to its disposable income. This has been the result of its net financial wealth increasing. Net financial wealth in 2010 was 9.8 per cent higher than in 2007. However, the depressed housing market has continued to adversely impact on the sector’s net worth. Physical wealth in 2010 was 0.7 per cent lower than in 2007.
Of course, while these empirical observations are undoubtedly interesting, the key question for debate is how these patterns affect household behaviour. Of particular importance, is how changes in both the household sector’s total net worth and the components making up the total will translate into changes in consumer spending. Economists are increasingly recognising that in understanding consumer spending patterns we need to gain a deeper understanding of the impact of the balance sheets on consumer spending. It is quite likely that many retailers when forming their plans for the year ahead will be analysing the potential impact of household finances on spending behaviour. Developing strategies to respond to the state of the household balance sheets may be crucial to their success.
