Here are a series of videos examining the case for and against austerity policy. Is such policy necessary to re-balance countries’ economies and retain or regain the confidence of investors? Or does such policy harm not just short-run growth but long-run growth too? Does it reduce investment and thereby aggregate supply?
These videos follow on from the news item Keynes versus the Classics: a new version of an old story. In the first video, Mark Blyth, author of Austerity: the History of a Dangerous Idea, argues that austerity policy has not worked and never can. George Osborne, by contrast, argues that although it has been a ‘hard road to recovery’, austerity policy is working.
International bodies take a more nuanced stand. The IMF, while supporting the objective of reducing the government deficit, argues that the pace of the cuts in the UK should be slowed until more robust growth returns. The OECD, in examining the global economy, is more supportive of countries maintaining the pace of deficit reduction, but argues that the ECB needs to take stronger monetary measures to boost bank lending in the eurozone.
With austerity having increasingly alarming effects on unemployment and social cohesion, especially within certain eurozone countries, such as Greece, Portugal and Spain, it is not surprising that there are growing demands for rethinking macroeconomic policy.
There is general agreement that more needs to be done to promote economic growth, and a growing consensus that an increase in infrastructure expenditure is desirable. But whether such expenditure should be financed by increased borrowing (with the extra deficit being reduced subsequently as a result of the extra growth), or whether it should be financed by reductions in expenditure elsewhere, is a continuing focus of debate.

An excellent learning exercise for students of economics is to take a journal article that uses data to model the economy and then try to replicate the authors’ results. You may well be given an assignment like this in future years of your degree.
One such exercise is used on the University of Massachusetts Amherst’s doctoral programme in economics. Thomas Herndon is a student on that degree and chose to examine a well-known and highly influential paper, Growth in a Time of Debt by Carmen Reinhart then of the University of Maryland and Kenneth Rogoff of Harvard University and former chief economist of the IMF. Professors Reinhart and Rogoff used new data on 44 countries spanning about 200 years.
A key finding of their paper, published in 2010 in the American Economic Review Papers and Proceedings, is that once a country’s government debt exceeds 90% of GDP, growth rates fall considerably: the median across countries by about 1% and the mean considerably more.
The paper has been hugely influential. It has been used to justify the austerity programmes being pursued in many countries, including the UK and the eurozone. Cutting the government deficit to GDP ratio, and ultimately the government debt to GDP ratio, has been seen as a way of achieving higher growth over the longer term, and justifies the adverse effect on short-term growth from the dampening of aggregate demand.
Well, this seemed an interesting paper for Thomas Herndon to examine, and he was keen to show just how Reinhart and Rogoff’s data led to their conclusions. But try as he might, he could not replicate their results. His initial reaction was to think he had made an error, but each time he checked he came back with the same conclusion: they must have made errors in their calculations.
His supervisor at Amherst, Professor Michael Ash, after Thomas had checked and checked again, realised that something was wrong. He encouraged Thomas to write to Reinhart and Rogoff to request sight of their dataset. They duly obliged and it was then that Thomas spotted various errors. These are explained in the articles below, but the overall effect was to alter the conclusion. Although high debt may undermine growth to some extent, the effect is much less than Reinhart and Rogoff concluded, and there are several exceptions to this rule.
On 15 April 2013, Thomas, along with his supervisor, Michael Ash and his colleague, Robert Pollin, published a response to the Reinhart and Rogoff paper. In the abstract to their paper, Does High Public Debt Consistently Stifle Economic Growth? A Critique of Reinhart and Rogoff they state that:
… coding errors, selective exclusion of available data, and unconventional weighting of summary statistics lead to serious errors that inaccurately represent the relationship between public debt and GDP growth among 20 advanced economies in the post-war period. They find that when properly calculated, the average real GDP growth rate for countries carrying a public-debt-to-GDP ratio of over 90 percent is actually 2.2 percent, not –0:1 percent as published in Reinhart and Rogoff. That is, contrary to RR, average GDP growth at public debt/GDP ratios over 90 percent is not dramatically different than when debt/GDP ratios are lower.
The authors also show how the relationship between public debt and GDP growth varies significantly by time period and country. Overall, the evidence we review contradicts Reinhart and Rogoff’s claim to have identified an important stylized fact, that public debt loads greater than 90 percent of GDP consistently reduce GDP growth.
So could this be you in the future? Will you take a famous paper and, by re-examining and reworking the data, find that its conclusions are wrong? Could you end up changing the world? Exciting stuff!

Questions
- What were the particular errors made by Reinhart and Rogoff?
- How has their paper been used as a basis for the design of macroeconomic policy?
- What are the limitations of using even accurate time-series data as the basis for policy measures?
- How might the work of Herndon change the direction of future macroeconomic policy?
- In his guest post in Business Insider (see link above), Herndon wrote: ‘The implication for policy is that, under particular circumstances, public debt can play a key role in overcoming a recession.’ What might this role be?
- Why might we have to be cautious in drawing policy conclusions from Herndon’s work?
There has been considerable discussion recently about whether the government should introduce a property tax on high value properties. The government, finding it difficult to reduce the public-sector deficit and yet determined to do so, is looking for additional measures to reduce government expenditure or raise tax revenue.
But would it favour a mansion tax as a means of raising additional revenue?
The imposition of such a tax is favoured by both Liberal Democrats and the Labour Party. It is strongly opposed, however, by Conservatives. But just what would such a tax look like and what are the arguments for and against it?
One alternative would be to impose a one-off tax on property valued over a certain amount, such as £2 million. Alternatively it could be levied only for as long as the government is seeking to make substantial inroads into the deficit.
Another would be to add one or more bands to council tax. At present, council tax in England is levied in 8 bands according to the value of a person’s property. The highest band is for property valued over £320,000 in 1991 prices, with the amount of tax due for each band varying from local authority to local authority. (Average UK house prices in 2012 are 135% higher than in 1991.) In Scotland the bands are lower with the top band being for property valued over £212,000 in 1991 prices. In Wales, there is an additional band for property valued over £424,000, but properties are valued in 2003 prices, not 1991 prices.
With low top bands for council tax, people in mansions end up paying the same as people in much more modest property. It would be relatively easy to add additional bands, with the top band applying only to property worth, say, over £1 million or more.
The arguments in favour of a mansion tax are that it is progressive, relatively easy to collect, hard to evade and with minimal disincentive effects. The arguments against are that it would make the tax system ‘too progressive’, would not necessarily be related to an individual’s ability to pay and could have substantial disincentive effects.
The progressiveness of the UK tax system is illustrated in the chart, which looks at the proportion of income paid in direct, indirect and all taxes by quintile groups of households – that is, households grouped into five equal sized groups ranked from lowest to highest gross income. (Click here for a PowerPoint of the chart.)
The following articles look at the debate as it has raged over the past few weeks. Try to unpick the genuine arguments from the political rhetoric!

With all the concerns recently about Greek and Italian debt and about the whole future of the eurozone, you would be forgiven for thinking that the problems of the UK economy had gone away. This couldn’t be further from the truth. Problems are mounting and pessimism is growing.
First there is the problem of a contracting eurozone economy. This will directly impact on the UK as almost half of UK exports go to eurozone countries. Second there is the impact of the government expenditure cuts, most of which have still not taken effect yet. Third there is the fact that, with the combination of inflation over 5% and nominal pay typically rising by no more than 2%, real take-home pay is falling and hence too is the volume of consumer expenditure. Fourth, there is the increasingly pessimistic mood of consumers and business. The more pessimistic people become about the prospects for their jobs and incomes, the more people will rein in their spending; the more pessimistic businesses become, the more they will cut back on investment and economise on stock holding.
Forecasts for the UK economy have become considerably bleaker over the past few weeks. These include forecasts by the National Institute for Economic and Social Research (NIESR), the accountancy network BDO, Ernst & Young’s ITEM Club and the CBI in its SME Trends Survey and November Economic Forecast. The Treasury’s latest Forecasts for the UK Economy, which brings together forecasts by 29 different organisations, also shows a marked increase in pessimism from September to October.
So is it now time for the government to change course to prevent the economy slipping back into recession? Do we need a Plan B? Certainly, it’s something we’ve considered before on this news site (see Time for a Plan B?). The latest call has come from a group of 100 leading academic economists who have written to the Observer. In their letter they spell out what such a plan should contain. You’ll find a link to the letter below and to other articles considering the proposals.

Questions
- What are the main proposals in Compass’s Plan B?
- How practical are these proposals?
- Without a Plan B, what is likely to happen to the UK economy over (a) the coming 12 months; (b) the next 3 years?
- Why might sticking to Plan A worsen the public-sector deficit – at least in the short term?
- What are the main arguments for sticking to Plan A and not easing up on deficit reduction?
- Find out what proportion of the UK’s debt is owed to non-UK residents? (See data published by the UK’s Debt Management Office (DMO).) How does this proportion and the average length of UK debt affect the arguments about the sustainability of this level of debt and the ease of servicing it?
- If you had to devise a Plan B, what would it look like and why? To what extent would it differ from Compass’s Plan B and from George Osborne’s “Plan A”?
The government is sticking to its deficit reduction plan. But with worries about a lack of economic recovery, or even a double dip recession, some economists are calling for a Plan B. They back up their arguments by referring to the lack of consumer confidence, falling real incomes and rising commodity prices. Without a slowing down in cuts and tax rises, the lack of aggregate demand, they claim, will prevent a recovery.
The government maintains that sticking to the cuts and tax rises helps maintain international confidence and thereby helps to keep interest rates low. Also, it argues, if the economy does slow down, then automatic stabilisers will come into play. Finally, even though fiscal policy is tight, monetary policy is relatively loose, with historically low interest rates.
But will there be enough confidence to sustain a recovery? Economists are clearly divided. But at least the IMF seems to think so. In its latest assessment of the UK economy, although it has cut the growth forecast for 2011 from 2% to 1.5%, that is still a positive figure and thus represents a recovery, albeit a rather fragile one.

- Is monetary policy loose enough? How could it be made looser, given that Bank rate is at the historically low level of 0.5% and could barely go any lower?
- What are automatic fiscal stablisers and how are they likely to affect aggregate demand if growth falters? What impact would this have on the public-sector deficit?
- What is meant by the ‘inventory cycle’? How did this impact on growth in 2010 and the first part of 2011?
