There has been an interesting debate recently about whether the austerity policies being pursued in the UK are the correct ones. What would have happened if the government had pursued a more expansionary policy? Would the increase in borrowing, at least in the short term, have triggered a financial crisis?
Without austerity policies, would the eurozone crisis have led to a collapse in investor confidence in the UK, especially if Greece had been forced out of the euro?
On the one side, Kenneth Rogoff argues that increasing the UK’s budget deficit would have been dangerous and could have led to a flight from the pound. Generally, but with some reservations, he supports the fiscal policies that have been pursued by the Coalition.
I am certainly not arguing that the UK or other advanced countries handled the post-crisis period perfectly. There should have been more infrastructure spending, even more aggressive monetary policy and probably more ruthless bank restructuring. But there has to be a balance between stimulus and stability. To assume we always knew things would calm down, and to retrospectively calibrate policy advice accordingly, is absurd
Paul Krugman and Simon Wren-Lewis challenge Rogoff’s arguments. Paul Krugman uses a version of the IS-LM model to analyse the effect of a loss of international confidence in the UK following problems in the eurozone and worries about excessive UK borrowing.
In the model, the LM curve (labelled MP in Krugman’s diagrams) illustrates the effect of an increase in real GDP on interest rates with a particular monetary policy (e.g. an inflation target or a Taylor rule, 
which involves a mix of two policy objectives: an inflation target and real GDP). As GDP rises, putting upward pressure on inflation, so the central bank will raise interest rates. Hence, like the traditional LM curve, the monetary-policy related LM curve will slope upwards, as shown in the diagram.
Initial equilibrium GDP is Y0. The rate of interest is at the minimum level, r0 (i.e. the rate of 0.5% that the Monetary Policy Committee has set since January 2009). This, in the model, is the liquidity trap, where any increase in money supply (a rightward shift in the LM curve) will have no effect on interest rates or GDP.
In Rogoff’s analysis of a crisis triggered by excessive borrowing and problems in the eurozone, the IS curve will shift to the left (as illustrated by curve IS1) as capital flows from the UK and confidence collapses. Real GDP will fall to Y1. This will be the outcome of fiscal expansion in the world of the early 2010s.
Krugman argues that the opposite will occur. The outflow of capital will drive down the exchange rate. This will lead to an increase in exports and a decrease in imports. Aggregate demand thus rises and the IS curve will shift to the right (e.g. to IS2 in the diagram. Real GDP will rise (e.g. to Y2 in the diagram). If the rise in aggregate demand is sufficient, the economy will rise out of the liquidity trap and interest rates will rise (e.g. to r2 in the diagram).
Not surprisingly, Rogoff challenges this analysis, as you will see if you read his second paper below. He doesn’t criticise the model per se, but challenges Krugman’s assumptions. For example, a depreciation of sterling by some 20% since 2008 doesn’t seem to have had a major effect in stimulating exports (see the chart in the news item, A balancing act). And exports could well have declined if the eurozone economy had collapsed, given that exports to the eurozone account for around 44% of total UK exports.
Rogoff’s assumptions in turn can be challenged. Simon Wren-Lewis argues that, provided a credible long-term plan for deficit reduction is in place, maintaining a fiscal stimulus in the short run, to keep the recovery going that was beginning to emerge in 2010, would help to increase investor confidence, not undermine it. And, with a policy of quantitative easing, which involves the Bank of England buying central government debt, there is no problem of a lack of demand for UK gilts by the private sector.
What is clear from this debate is the willingness of both sides to accept points made by the other. It is an extremely civilised debate. In fact, it could be seen as a model of how academic debate should be conducted. There is none of the ‘shouting’ that has charaterised much of the pro- and anti-austerity lobbying since the financial crisis burst onto the world stage.

The latest preliminary GDP estimates for 2013 Q3 suggest that the economy’s output (real GDP) expanded by 0.8 per cent following on the back of a 0.7 per cent increase in Q2. Growth was observed across the main industrial sectors with the important service sector growing by 0.7 per cent. While the output of the service sector is now 0.5 per cent higher than its 2008 Q1 peak, the total output of the economy remains 2.6 per cent below its 2008 Q1 peak.
The volatility of growth underpins the idea of business cycles and on occasions results in recessions. Today’s release needs to be set in the context of this volatility and in the context of 2008/9 recession which saw output fall by 7.2 per cent. UK output peaked in 2008 Q1 (£392.786 billion at 2010 prices). There then followed 6 quarters during which output declined.
Output declined again in 2010 Q4 (–0.2% growth) and again in 2011 Q4 (–0.1% growth). The estimates of real GDP for 2011 Q4 and 2012 Q1 are identical at £376.462 billion (at 2010 prices). Previous revisions have seen the 2012 Q1 growth number revised up so that a further recession resulting in a double-dip recession no longer appears in the figures.
While output is now portrayed as (very) flat in 2012 Q1, it did fall again in 2012 Q2 (–0.5 per cent growth) and in 2012 Q4 (–0.3 per cent growth). Moving forward in time, the latest ONS numbers show an economy that grew by 0.4 per cent in 2013 Q1 (to £377.301 billion at 2010 prices), by 0.7 per cent in 2013 Q2 (to £379.780 billion at 2010 prices) and by 0.8 per cent in 2013 Q3 billion (to £382.818 billion at 2010 prices). Compared with 2012 Q3, the output of the UK economy in 2013 Q2 is 1.5 per cent higher.
Chart 1 helps to put the recent growth numbers into an historical context. It shows the quarterly change in real GDP since the 1980s. From it, we can see the 5-quarter recession that commenced in 1980 Q1 when output shrunk by 4.6 per cent, the 5-quarter recession that commenced in 1990 Q3 when output shrank by 2.4 per cent and the 6-quarter recession that commenced in 2008 Q2 when output shrank by 7.2 per cent. (Click here to download a PowerPoint of the chart.)
Chart 2 scratches a little below the surface by looking at output by the four principal industrial types. The interesting finding is that the output of the service sector has now risen above its 2008 Q1 peak. In 2013 Q3 output is 0.5 per cent larger. By contrast, the other three sectors remain smaller than in 2008 Q1. Agriculture, forestry and fisheries is 5.9 per cent smaller, construction 14.3 per cent smaller and production (including manufacturing) is 14.6 per cent smaller. (Click here to download a PowerPoint of the chart.)
With today’s release, quarterly growth now averages –0.11 per cent since 2008 Q2. If we take the series back to the mid 1950s when it began, the average quarterly rate of growth is 0.64 per cent which is equivalent to an annual rate of increase of 2.57 per cent. While today’s news is encouraging it remains important to keep it in perspective and to ensure that growth is sustainable and built on firm foundations.

One very important characteristic of economic growth is its short-term volatility. The volatility of growth underpins the idea of business cycles and on occasions results in recessions. The traditional definition is where real GDP (output) declines for 2 or more consecutive quarters. Interestingly, the latest GDP numbers contained in the Quarterly National Accounts mean that the recession previously evidenced from 2011 Q4 to 2012 Q2 has effectively disappeared. Nonetheless, output today is still 3.3 per cent lower than before the 2008 economic downturn.
The ONS’s latest output numbers raise some interesting questions around our understanding of what constitutes a recession. Should, for instance, we define it solely in terms of real GDP and, even if we do, is a strict statistical definition based around two consecutive quarterly falls appropriate? The recent estimates from the ONS show that the 2008/9 recession saw output fall by 7.2 per cent. They show that UK output peaked in 2008Q1 (£392.786 billion at 2010 prices). There then followed 6 quarters during which output declined.
Output declined again in 2010 Q4 (-0.2% growth) and again in 2011 Q4 (-0.1% growth). The new estimates of real GDP for 2011 Q4 and 2012 Q1 are now identical at £376,462 billion (at 2010 prices). Previous revisions have also seen the 2012 Q1 growth number revised up and, hence, a further recession resulting in a double-dip recession has effectively now been statistically removed. The 2013 Q1 Quarterly National Accounts revised growth up so that 2012 Q1 only saw a percentage fall when measured to the third decimal place (–0.007% growth).
While output is now portrayed as (very) flat in 2012 Q1, it did fall again in 2012 Q2 (-0.5 per cent growth) and in 2012 Q4 (-0.3 per cent growth). Moving forward in time, the latest ONS numbers show that the economy grew by 0.4 per cent in 2013 Q1 (to £377,301 billion at 2010 prices) and by 0.7 per cent in 2013 Q2 (to £379,780 billion at 2010 prices). Despite this, output remains 3.3 per cent below its 2008 Q1 peak. A more positive spin on the numbers would be to point out that output is up 4.2 per cent from its 2009 Q3 trough (£364,557 billion at 2010 prices).
Perhaps the debate around the appearance and disappearance of recessions in official data strengthen the argument for a more holistic and considered view of what constitutes a recession. In the USA the wonderfully-named Business Cycle Dating Committee takes a less fixed view of economic activity and, hence, of recessions. Its website argues:
It (the Committee) examines and compares the behavior of various measures of broad activity: real GDP measured on the product and income sides, economy-wide employment, and real income. The Committee also may consider indicators that do not cover the entire economy, such as real sales and the Federal Reserve’s index of industrial production (IP).
Of course, the advantage of focusing on real GDP alone in measuring activity and in determining recessions is that it is usually very straightforward to interpret. Regardless of whether the UK did or did not experience a recession at the end of 2011 and into 2012, the chart helps to put the recent growth numbers into an historical context. It shows the quarterly change in real GDP since the 1980s.
From the chart, we can see the 5-quarter recession that commenced in 1980 Q1 when output shrunk by 4.6 per cent, the 5-quarter recession that commenced in 1990 Q3 when output shrank by 2.4 per cent and the 6-quarter recession that commenced in 2008 Q2 when output shrank by 7.2 per cent. (Click here to download a PowerPoint version of the chart.)
The chart allows to see the other characteristic of growth too: over the long run growth is positive. Since 1980, the average rate of growth per quarter has been 0.57 per cent. This is equivalent to an average rate of growth of 2.3 per cent per year.
Since 2008 Q2, quarterly growth has averaged -0.16 per cent which is equivalent to an annual rate of growth of -0.63 per cent! In any language these are extraordinary numbers and certainly help to put the recent rebound in growth into context.

You may have been following the posts on the US debt ceiling and budget crisis: Over the cliff and Over the cliff: an update. Well, after considerable brinkmanship over the past couple of weeks, and with the government in partial shutdown since 1 October thanks to no budget being passed, a deal was finally agreed by both Houses of Congress, less than 12 hours before the deadline of 17 October. This is the date when the USA would have bumped up against the debt ceiling of $16.699 trillion and would be in default – unable to borrow sufficient funds to pay its bills, including maturing debt.
But the deal only delays the problem of a deeply divided Congress, with the Republican majority on the House of Representatives only willing to make a long-term agreement in exchange for concessions by President Obama and the Democrats on the healthcare reform legislation. All that has been agreed is to suspend the debt ceiling until 7 February 2014 and fund government until 15 January 2014.
A more permanent solution is clearly needed: not just one that raises the debt ceiling before the next deadline, but one which avoids such problems in the future. Such concerns were echoed by Christine Lagarde, Managing Director of the International Monetary Fund (IMF), who issued the following statement:
The U.S. Congress has taken an important and necessary step by ending the partial shutdown of the federal government and lifting the debt ceiling, which enables the government to continue its operations without disruption for the next few months while budget negotiations continue to unfold.
It will be essential to reduce uncertainty surrounding the conduct of fiscal policy by raising the debt limit in a more durable manner. We also continue to encourage the U.S. to approve a budget for 2014 and replace the sequester with gradually phased-in measures that would not harm the recovery, and to adopt a balanced and comprehensive medium-term fiscal plan.

Questions
- Explain what is meant by default and how the concept applies to the USA if it had not suspended or raised its budget ceiling.
- Is the agreement of October 16 likely to ‘reassure markets’? Explain your reasoning.
- What is likely to happen to long-term interest rates as a result of the agreement?
- Will the imposition of a new debt ceiling by February 2014 remove the possibility of using fiscal policy to stimulate aggregate demand and speed up the recovery?
- What is meant by ‘buy the rumour, sell the news’ in the context of stock markets? How was this relevant to the agreement on the US debt ceiling and budget?
In a News Item of 1 October, Over the Cliff, we looked at the passing of the deadline that same day for Congress to agree a budget. We also looked at the looming deadline for Congress to agree a new higher ceiling for Federal Government debt, currently standing at $16.699 trillion. Without an agreement to raise the limit, the government will start becoming unable to pay some of its bills from around 17 October.
One week on and no agreement has been reached on either a budget or a higher debt ceiling.
Failure to agree on a budget has led to the ‘shut-down’ of government. Only essential services are being maintained; the rest are no longer functioning and workers have been sent home on ‘unpaid leave’. This has led to considerable hardship for many in the USA. It has had little effect, however, on the rest of the world, except for tourists to the USA being unable to visit various national parks and monuments.
Failure to raise the debt ceiling, however, could have profound consequences for the rest of the world. It could have large and adverse effects of global growth, global trade, global investment and global financial markets. The articles below explore some of these consequences.
