Category: Economics: Ch 19

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.

Questions

  1. Explain how the policy-dependent LM curve illustrated in the diagram is derived.
  2. What would cause the policy-dependent LM curve to shift?
  3. Explain what is meant by the ‘liquidity trap’. Why does being in a liquidity trap make monetary policy ineffective?
  4. How would you determine whether or not the UK is currently in a liquidity trap?
  5. How is the level of (a) public-sector debt and (b) private sector debt owed overseas likely to affect the confidence of investors concerning the effects of an expansionary fiscal policy?
  6. Compare the UK’s total external debt with that of other countries (see the following tables from Principal Global Indicators, hosted by the IMF: External debt and Short-term external debt).
  7. What insurance policy (if any) does the UK have to protect against market panic about the viability of UK debt?
  8. What areas of agreement are there between Rogoff on the one side and Krugman and Wren-Lewis on the other?

As we saw in the news item The difficult exit from cheap money, central banks around the world have been operating an extremely loose monetary policy since the beginning of 2009. Their interest rates have been close to zero and trillions of dollars of extra money has been injected into the world economy through various programmes of quantitative easing.

For the past few months the Federal Reserve has been purchasing bonds under its most recent programme dubbed QE3, and thereby increasing narrow money, by $85 billion per month. Since the start of its QE programme in 2009, it has pumped around $2.8 trillion of extra money into the US and world economies. This huge increase in money supply has boosted the demand for assets worldwide and world stock markets have risen. Much of the money has flowed into developing countries, such as India, and has acted as a boost to their economies.

Once the US economy is growing strongly again, the aim is to taper off, and ultimately end or even reverse, the QE programme. It was expected that the Fed would decide to start this tapering off process at its meeting on 18 September – perhaps reducing bond purchases initially by some $10 billion. (Note that this would still be an increase in money supply, just a slightly smaller one.) Over the past few days, US bond prices have been falling (and yields increasing) in anticipation of such a move.

As it turned out, the Fed decided to delay tapering off. It will continue with its assets purchase programme of $85 billion per month for the time being. The reason given was that the US economy was still too fragile and needed the monthly injections of money to stay at the current level.

Normally it might be expected that the announcement of a more fragile recovery would cause the US stock market, and others worldwide, to fall. In fact the opposite occurred, with investors relieved that the extra money, which allows extra asset purchases, would continue at the same rate.

But this then raises the question of just what will be the effect when tapering off does actually occur. Will stock markets then go into a tailspin? Or will they merely stop rising so fast. That depends very much on the role of speculation.

Questions

  1. Why might a slowing down in the increase in US money supply cause asset prices to fall, rather than merely to rise less quickly?
  2. Why has the US QE programme led to a rise in asset prices overseas?
  3. Distinguish between stabilising and destabilising speculation. Which type of speculation has been occurring as a result of the US QE programme?
  4. How has QE affected unemployment in the UK and USA? How is the participation rate and the flexibility of labour markets relevant to the answer?
  5. Explain the following two statements by Stephanie Flanders and Robert Peston respectively. “The market conditions argument has a circularity to it: talk of tapering leads to higher market rates, which in turn puts the taper itself on hold.” “The Fed simply hinting that less money would be created, means that there will be no reduction in the amount of money created (for now at least).”
  6. Why have US long-term interest rates, including mortgage rates, risen since May of this year?
  7. What impact have higher US long-term interest rates had on economies in the developing world? Explain.

On 15 September 2008, Lehman Brothers, the fourth-largest investment bank in the USA, filed for bankruptcy. Although the credit crisis had been building since mid 2007, the demise of Lehmans was a pivotal event in the unfolding of the financial crisis and the subsequent severe recession in most developed economies. Banks were no longer seen as safe and huge amounts of government money had to be poured into banks to shore up their capital and prevent further bankruptcies. Partial nationalisation seemed the only way of rescuing several banks and with it the global financial system.

A deep and prolonged recession followed (see Chart 1: click here for a PowerPoint). In response, governments pursued expansionary fiscal policies – at least until worries about rising government deficits and debt caused a lurch to austerity policies. And central banks pursued policies of near zero interest rates and subsequently of quantitative easing. But all the time debate was taking place about how to reform banking to prevent similar crises occurring in the future.

Solutions have included reform of the Basel banking regulations to ensure greater capital adequacy. The Basel III regulations (see Chart 2) demand considerably higher capital ratios than the previous Basel II regulations.

Other solutions have included proposals to break up banks. Indeed, just this week, the Lloyds Banking Group has hived off 631 of its branches (one sixth of the total) into a newly reformed TSB. Another proposal is to ring-fence the retail side of banks from their riskier investment divisions. In both cases the aim has been to avoid the scenario where banks are seen as too big to fail and can thus rely on governments to bail them out if they run into difficulties. Such reliance can make banks much more willing to take excessive risks. Further details of the new systems now in place are given in the Robert Peston article below.

But many critics maintain that not nearly enough has been done. Claims include:

• The Basel III rules are not tough enough and banks are still being required to hold too little capital.
• Rewards to senior bankers and traders are still excessive.
• The culture of banking, as a result, is still too risk loving in banks’ trading arms, even though they are now much more cautious about lending to firms and individuals.
• This caution has meant a continuing of the credit crunch for many small businesses.
• Higher capital adequacy ratios have reduced bank lending and have thus had a dampening effect on the real economy.
• The so-called ring-fences may not be sufficient to insulate retail banking from problems in banks’ investment divisions.
• Banks are not being required to hold sufficient liquidity to allow them to meet customers’ demands for cash in all scenarios.
• Banks’ reliance on each other still leaves a systemic risk for the banking system as a whole.
• Fading memories of the crisis are causing urgency to tackle its underlying problems to diminish.
• Problems may be brewing in less regulated parts of the banking world, such as the growing banking sector in China.

The following articles look at the lessons of the banking crisis – those that have been learned and those that have not. They look at the measures put in place and assess whether they are sufficient.

Questions

  1. Why did Lehman Brothers collapse?
  2. Explain the role of the US sub-prime mortgage market in the global financial crisis of 2007/8.
  3. In the context of banking, what is meant by (a) capital adequacy; (b) risk-based capital adequacy ratios; (c) leverage; (d) leverage ratios?
  4. Explain the Basel III rules on (a) risk-based capital adequacy (see the textbook and the chart above); (b) non-risk-based leverage (introduced in 2013: see here for details).
  5. Explain and comment on the following statement by Adair Turner: ‘We created an over-leveraged financial system and an over-leveraged real economy. We created a system such that even if the direct cost of bank rescue was zero, the impact of their near-failure on the economy was vast.’
  6. Under what circumstances might the global financial system face a similar crisis to that of 2007/8 at some point in the future?
  7. Why is there an underlying conflict between increasing banks’ required capital adequacy and ensuring a sufficient supply of credit to consumers and business? What multiplier effects are likely to occur from an increase in the capital adequacy ratio?

UK unemployment fell by 4000 to 2.51 million in second quarter of this year. But this was too small to have any significant effect on the unemployment rate, which remained at 7.8%.

According to the forward guidance issued by the Bank of England, Bank Rate will stay at 0.5%, barring serious unforeseen circumstances, until unemployment reaches 7%. So will this be soon?

There are good reasons to suggest that the answer is no. Reasons include the following:

(a) Many firms may choose to employ their part-time workers for more hours, rather than taking on extra staff, if the economy picks up.

(b) The recovery is being fuelled by a rise in consumption, which, in turn, is being financed by people drawing on savings or borrowing more. The household saving ratio fell from 7.4% in 2012 Q1 to 4.2% in 2013 Q1. This trend will be unsustainable over the long run, especially as the Bank of England may see a rapid rise in borrowing/decline in saving as serious enough to raise interest rates before the unemployment rate has fallen to 7%.

(c) Despite the modest recovery, people’s average real incomes are well below the levels prior to the deep recession of 2008/9.

There’s some good news and some bad news about the UK economy. The good news is that there are signs that the recovery is gathering momentum; the ‘green shoots’ are growing bigger. The bad news is that it’s the ‘wrong type of growth’!

One of the main underlying problems of the 2008 financial crisis was that household debt had been increasing to unsustainable levels, egged on by banks only too willing to lend, whether as personal loans, on credit cards or through mortgages. When the recession hit, many people sought to reduce their debts by cutting back on spending. This further fuelled the recession.

What the government and most economists hoped was that there would be some rebalancing of the economy, with less reliance on consumer spending to drive economic growth. Instead it was hoped that growth would be driven by a rise in investment and exports. Indeed, the 25% depreciation of sterling exchange between 2007 and 2009 was seen as a major advantage as this would boost the demand for exports and encourage firms to invest in the export sector.

But things haven’t turned out the way people hoped. The recession (or lack of growth) has been much deeper and more prolonged than previous downturns in the economy. Today, real GDP per head is more than 7% below the level in 2007 and many people have seen much bigger declines in their living standards.

But also, despite the austerity policies, the economy has not been ‘rebalanced’ towards exports and investment. Exports are 3% lower than in 2006 (although they did grow between 2009 Q2 and 2011 Q1, but have since stagnated). And investment is 27% lower than in 2006. Household consumption, however, has grown by about 2% and general government consumption by around 9% since 2006. The chart shows the figures, based on 2006 Q1 = 100.
(Click here for a PowerPoint of the chart.)

And recent evidence is that consumption is beginning to grow faster – not because of rising household incomes, but because of falling saving rates. In 2008, the household saving ratio had fallen to nearly 0% (i.e. households were on average saving about the same as they were borrowing). Then the saving ratio rose dramatically as people reined in their spending. Between 2009 and 2012, the ratio hovered around 7%. But in the first quarter of 2013, it had fallen to 4.2%

So the good news is that aggregate demand is rising, boosting economic growth. But the bad news is that, at least for the time being, this growth is being driven by a rise in household borrowing and a fall in household saving. The videos and articles consider whether this is, however, still good news on balance.
