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.

In an interview with the Yorkshire Post, Mark Carney, Governor of the Bank of England, said that under current circumstances he did not feel that further quantitative easing was justified. He said:
My personal view is, given the recovery has strengthened and broadened, I don’t see a case for quantitative easing and I have not supported it.
In response to his speech, the pound strengthened against the dollar. It appreciated by just over 1 cent, or 0.7%. But why should the likelihood of no further quantitative easing lead to a strengthening of the pound?
The answer lies with people’s anticipation of future interest rates. If there is no further increase in money supply through QE, interest rates are likely to rise as the economy recovers and thus the demand for money rises. 
A rise in interest rates, in turn, is likely to lead to an inflow of finance into the country, thereby boosting the financial account of the balance of payments. The increased demand for sterling will tend to drive up the exchange rate.
However, an increase in aggregate demand will result in an increase in imports and a likely increase in the balance of trade deficit. Indeed, in July (the latest figures available) the balance of trade deficit rose to £3.085bn from £1.256bn in June. As recovery continues, the balance of trade deficit is likely to deteriorate further. Other things being equal, this would lead to a depreciation of the pound.
So if the pound appreciates, this suggests that the effect on the financial account is bigger than the effect on the current account – or is anticipated to be so. In fact, given the huge volumes of short-term capital that move across the foreign exchanges each day, financial account effects of interest rate changes – actual or anticipated – generally outweigh current account effects.

Turkey has experienced rapid economic growth in recent years and has attracted large inflows of foreign capital. The chart below illustrates how growth in real GDP in Turkey in most years since 2000 has considerably exceeded that in the OECD as a whole (click here for a PowerPoint). As you can see from the chart, growth in Turkey over the period has averaged 4.5%, while that in the OECD has averaged just 1.8%.
Indeed, Turkish growth has been compared with that of the BRICs (Brazil, Russia, India and China). However, like the BRICs, Turkey has been experiencing slowing growth in the past few months. Indeed, the slowdown has been especially marked in Turkey.
In recent years Turkey has benefited from large inflows of foreign capital. Partly these were direct investment flows, encouraged by a large and rapidly growing internal market, boosted by a rapid expansion of consumer credit, and also by a growing export sector. But to a large extent, especially in recent years, there has been a large rise in portfolio and other investment inflows. This has been encouraged by a large increase in global money supply resulting from policies of quantitative easing in the USA and other developed countries.
But the economic climate has changed. First investors have become worried about the conflict in Syria escalating and this impacting on Turkey. Second Turkey’s large financial account surpluses have allowed it to run large current account deficits and have maintained a high exchange rate. Third the tapering off and possible reversal of quantitative easing have led to recent outflows of finance from various countries perceived as being vulnerable, including Turkey.
The effect of this has been a depreciation of the Turkish lira and upward pressure on inflation. The lira has fallen by 14% since the beginning of 2013 and by nearly 7% since the beginning of August alone.
The question is whether the supply side of the Turkish economy has become robust enough to allow the country to ride out its current difficulties. Will foreign investors have sufficient faith in the long-term potential of the Turkish economy to continue with direct investment, even if short-term financial inflows diminish?

The rate of growth in India has fallen to its lowest level since the first three months of 2009 – the period when many countries were plunging into recession. Although the annual rate was still 4.4% in Q2 2013 (a rate most Western governments would love to achieve!), it had averaged 8.2% from 2003 to 2007 and 9.5% from 2010 to 2011 (see).
And the rupee has been falling in value (see chart below). The exchange rate of the rupee to the dollar has depreciated by 21% since the start of the year and by 14% since the beginning of August (click here for a PowerPoint of the chart). This has pushed up the price of imports and raised fears that inflation, already approaching 10%, will rise.
There have also been concerns about the health of India’s banking sector, with worries over the possible rise in bad loans.
One result of all these factors is that the confidence of investors has been shaken. Bond prices have fallen and so too have share prices. The Mumbai Sensex index fell by 11.5% from 22 July to 27 August. Worried about possible capital flight, the Indian government imposed capital controls on Indian residents on 14 August. It has, however, since ruled out limiting the outflow of funds by foreign investors.

Japan has suffered from deflation on and off for more than 20 years. A problem with falling prices is that they discourage spending as people wait for prices to fall further. One of the three elements of the Japanese government’s macroeconomic policy (see Japan’s three arrows) has been expansionary monetary policy, including aggressive quantitative easing. A key aim of this is to achieve an inflation target of 2% and, hopefully, propel the economy out of its deflationary trap.
The latest news, therefore, from Japan would seem to be good: consumer prices rose 0.4% in June – the first rise for more than a year. But while some analysts see the rise in prices to be partly the result of a recovery in demand (i.e. demand-pull inflation), others claim that the inflation is largely of the cost-push variety as the weaker yen has increased the price of imported fuel and food.
If Japanese recovery is to be sustained and broadly based, a growth in real wages should be a core component. As it is, real wages are not growing. This could seriously constrain the recovery. For real wages to grow, employers need to be convinced that economic recovery will be sustained and that it would be profitable to take on more labour.
The success of the expansionary policy, therefore, depends in large part on its effect on expectations. Do people believe that prices will continue to rise? Do employers believe that the economy will continue to expand? And do people believe that their real wages will rise?

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?
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).
