In a carefully argued article in the New Statesman, the UK Business Secretary, Vince Cable, considers the slow recovery in the economy and whether additional measures should be adopted. He sums up the current state of the economy as follows:

The British economy is still operating at levels around or below those before the 2008 financial crisis and roughly 15 per cent below an albeit unsustainable pre-crisis trend. There was next to no growth during 2012 and the prospect for 2013 is of very modest recovery.

Unsurprisingly there is vigorous debate as to what has gone wrong. And also what has gone right; unemployment has fallen as a result of a million (net) new jobs in the private sector and there is vigorous growth of new enterprises. Optimistic official growth forecasts and prophets of mass unemployment have both been confounded.

He argues that supply-side policies involving “a major and sustained commitment to skills, innovation and infrastructure investment” are essential if more rapid long-term growth is to be achieved. This is relatively uncontroversial.

But he also considers the claim that austerity has kept the economy from recovering and whether policies to tackle the negative output gap should be adopted, even if this means a short-term increase in government borrowing.

But crude Keynesian policies of expanding aggregate demand are both difficult to implement and may not take into account the particular circumstance of the current extended recession – or depression – in the UK and in many eurozone countries. World aggregate demand, however, is not deficient. In fact it is expanding quite rapidly, and with the sterling exchange rate index some 20% lower than before the financial crisis, this should give plenty of opportunity for UK exporters.

Yet expanding UK aggregate demand is proving difficult to achieve. Consumers, worried about falling real wages and large debts accumulated in the years of expansion, are reluctant to increase consumption and take on more debts, despite low interest rates. In the light of dampened consumer demand, firms are reluctant to invest. This makes monetary policy particularly ineffective, especially when banks have become more risk averse and wish to hold higher reserves, and indeed are under pressure to do so.

So what can be done? He argues that there is “some scope for more demand to boost output, particularly if the stimulus is targeted on supply bottlenecks such as infrastructure and skills.” In other words, he advocates policies that will simultaneously increase both aggregate demand and aggregate supply. Monetary policy, involving negative real interest rates and quantitative easing, has helped to prevent a larger fall in real aggregate demand and a deeper dive into recession, but the dampened demand for money and the desire by banks to build their reserves has meant a massive fall in the money multiplier. Perhaps monetary policy needs to be more aggressive still (see the blog post, Doves from above), but this may not be sufficient.

Which brings Dr Cable to the political dynamite! He advocates an increase in public investment on infrastructure (schools and colleges, hospitals, road and rail projects and housing, and considers whether this should be financed, not by switching government expenditure away from current spending, but by borrowing more.

Such a strategy does not undermine the central objective of reducing the structural deficit, and may assist it by reviving growth. It may complicate the secondary objective of reducing government debt relative to GDP because it entails more state borrowing; but in a weak economy, more public investment increases the numerator and the denominator.

He raises the question of whether the balance of risks has changed: away from the risk of increased short-term borrowing causing a collapse of confidence to the risk of lack of growth causing a deterioration in public finances and this causing a fall in confidence. As we saw in the blog post Moody Blues, the lack of growth has already caused one ratings agency (Moody’s) to downgrade the UK’s credit rating. The other two major agencies, Standard & Poor’s and Fitch may well follow suit.

The day after Dr Cable’s article was published, David Cameron gave a speech saying that the government would stick to its plan of deficit reduction. Not surprisingly commentators interpreted this as a split in the Coalition. Carefully argued economics from Dr Cable it might have been, but political analysts have seen it as a hand grenade, as you will see from some of the articles below.

With the UK and eurozone economies in recession and with business and consumer confidence low, the Bank of England and the ECB have sprung into action.

The ECB has cut its main refinancing rate from 1% to an all-time low of 0.75%. Meanwhile, the Bank of England has embarked on a further round of quantitative easing (QE). The MPC voted to inject a further £50 billion through its asset purchase scheme, bring the total to £375 billion since QE began in March 2009.

And it is not just in Europe that monetary policy is being eased. In Australia and China interest rates have been cut. In the USA, there have been further asset purchases by the Fed and it is expected that the Japanese central bank will cut rates very soon, along with those in Korea, Indonesia and Sri Lanka.

But with consumers seeming reluctant to spend and businesses being reluctant to invest, will the new money in the UK and elsewhere actually be lent and spent? Or will it simply sit in banks, boosting their liquidity base, but doing little if anything to boost aggregate demand?

And likewise in the eurozone, will a 25 basis point reduction in interest rates (i.e. a 0.25 percentage point reduction) do anything to boost borrowing and spending?

It is like pushing on a string – a term used by Keynesians to refer to the futile nature of monetary policy when people are reluctant to spend. Indeed the evidence over the past few years since QE started is that despite narrow money having risen massively, M4 lending has declined (see chart).

With the deepening euro crisis, the slide back into recession in many developed countries and the slowing down of fast-growing developing countries, such as China and India, confidence is waning.

But just as pessimism increases, so too does uncertainty. The global economy is getting more and more difficult to forecast. So should economists give up trying to forecast? Should we rely on guesswork and hunch, or looking into crystal balls?

Bank of England representatives have been appearing before the Treasury Select Committee. And they have reiterated the consensus that things are getting more difficult to forecast. As Mervyn King said in his evidence:

There is just enormous uncertainty out there. I have no idea what is going to happen in the euro area.

And this uncertainty is making people cautious, which, in turn, damages recovery. As Dr King went on to say:

There is no doubt that with the additional uncertainty this year there’s evidence of people behaving in a very defensive way, being unwilling to invest and of course the most extreme example of that would be if we were to get to a liquidity trap where essentially the main assets people wanted to hold were claims on the central bank.

Part of the reason for the uncertainty about global growth prospects is uncertainty about what European leaders will decide about the future of the eurozone. Another is uncertainty about how people will respond to the uncertainty of others. But predicting how others will predict is very difficult as they will themselves be predicting what others will predict. This dilemma was observed by Keynes when observing how investors on the stock market behaved, all trying to predict what others will do, and is known as the Keynesian Beauty Contest dilemma (see also).

So are governments and central banks powerless to counteract the uncertainty and pessimism? Can they restore confidence and growth? Members of the Bank of England’s Monetary Policy Committee believe that further action can be taken to stimulate aggregate demand. Further quantitative easing and cuts in interest rates could help as, according to Dr King, we are not yet in a liquidity trap.

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’.

As the prospects for the global recovery become more and more gloomy, so the need for a boost to aggregate demand becomes more pressing. But the scope for expansionary fiscal policy is very limited, given governments’ commitments around the world to deficit reduction.

This leaves monetary policy. In the USA, the Federal Reserve has announced a policy known as ‘Operation Twist’. This is a way of altering the funding of national debt, rather than directly altering the monetary base. It involves buying long-term government bonds in the market and selling shorter-dated ones (of less than three years) of exactly the same amount ($400bn). The idea is to drive up the price of long-term bonds and hence drive down their yield and thereby drive down long-term interest rates. The hope is to stimulate investment and longer-term borrowing generally.

Meanwhile in Britain it looks as if the Bank of England is about to turn to another round of quantitative easing (QE2). The first round saw £200bn of asset purchases by the Bank between March 2009 and February 2010. Up to now, it has resisted calls to extend the programme. However, it is now facing increased pressure to change its mind, not only from commentators, but from members of the government too.

But will expansionary monetary policy work, given the gloom engulfing the world economy? Is there a problem of a liquidity trap, whereby extra money will not actually create extra borrowing and spending? Many firms, after all, are not short of cash; they are simply unwilling to invest in a climate of falling sales and falling confidence.

This podcast is from the Library of Economics and Liberty’s EconTalk site. In it, Scott Sumner of Bentley University discusses with host Russ Roberts the role of monetary policy in the USA since 2007 and whether or not it was as expansionary as many people think.

In fact, Sumner argues that monetary policy was tight in late 2008 and that this precipitated the recession. He argues that the standard indicators of the tightness or ease of monetary policy, namely the rate of interest and the growth in the money supply, were misleading.

Sumner on Monetary Policy EconTalk podcast (9/11/09)

After the November 2009 meeting of the Monetary Policy Committee, the Bank of England announced that it would keep Bank Rate on hold at 0.5%, at which rate it has been since March. It also said that it would spend a further £25 billion over the next three months on asset purchases, primarily government bonds, thereby pumping additional money into the economy: the process known as “quantitative easing“. This would bring total asset purchases under the scheme to £200bn.

But although this represents a further increase in money supply, the rate of increase is slowing down. In the previous three months, £50 billion of assets had been purchased. So does this imply that the Bank of England sees a recovery around the corner? Will money supply have been expanded enough to finance the desired increase in spending – on both consumption and investment?

A problem so far is that most of the extra money has not been spent on goods and services. Banks have been building up their reserves, with much of the money simply being re-deposited in the Bank of England as reserve balances (see Table A1.1.1 in “Bankstats). At the same time, households have been taking on very little extra debt – indeed, In July, total household debt actually fell (see “Payback time) and consumer debt (i.e. excluding mortgages) has continued to fall. If quantitative easing is to work, the money must be spent!

But with the monetary base having expanded so much, is there a danger that, once the recovery gathers pace, spending growth will return with a vengeance? Will inflation rapidly become a problem again with an overheating economy? The following articles examine the issues.

The current recession has seen the re-emergence of many of the intellectual battles fought amongst economists between the two worlds wars and again from the 1960s to the 1980s. The current debate has hinged around the appropriate policy response to the current recession. Is the solution a Keynesian one of stimulating aggregate demand; or is it a new classical one of keeping public spending under control to make room for private spending and to allow the market to function to best effect? And what about banking reform? What are the arguments here? The following articles by Lord Skidelsky examine the debate.
