Bryan Gould: Global crisis shows need for revision of economics

Add a comment

As the global crisis unfolds, the great gurus of the world economy - those who have presided over its fortunes for much of the last two or three decades - have largely ducked for cover.

Some, like economist Alan Greenspan, have had the courage to admit there was a "flaw" in their thinking. Others - like British Prime Minister Gordon Brown - have made an apparently effortless overnight conversion to Keynesian economics after decades of monetarist orthodoxy. A few - like Wall Street money manager Bernard Madoff - have been unmasked as fraudulent, as well as foolishly irresponsible.

But most have watched from the sidelines, silent and confused, as the results of their handiwork have become apparent.

The immediate task and focus of governments around the world is, of course, to put in place measures which will limit the damage, avoid a depression, and restore the world economy to some semblance of health as soon as possible. In this endeavour, the supposed experts of yesterday necessarily have little to say.

It is, after all, their nostrums that have driven us to this point, and the crisis has cruelly exposed the limitations of the monetary policy which they said was all that was needed. What does liquidity matter if no one wants to borrow and spend?

But, once the authorities have done their best, and the course to recovery of a sort is (hopefully) set, the debate will move on. The issue then will be not so much the steps needed for recovery as the lessons to be learned if the disaster is not to be repeated in the future.

At that point, we can expect the champions of "free" markets to re-enter the debate. The battle will then be on to write (or rewrite) history, and what now seems undeniable will again become hotly contested.

There will be no shortage of explanations and excuses for what has happened, ranging from the nonchalant (the crisis was a minor blip in what has otherwise been a triumph for the "free" market) to the aggressively ideological (it was the failures and mistake of governments that frustrated and distorted legitimate market operations).

It is vital, therefore, that - while reality still imposes itself on perceptions - an account is drawn up of the lessons we must learn from this disastrous episode. Some of those lessons will be widely accepted, but others - even for those who are most critical of the errors of recent times - will be more difficult to digest.

The crisis has been so damaging and so all-engulfing that it might be argued that virtually nothing of past doctrine can survive. There are some particular lessons, however, that absolutely demand attention. I would select six leading contenders.

The first and most obvious is that "free" or unregulated markets are extremely dangerous mechanisms which inevitably go wrong. All markets, left unregulated, will produce extremes, and that is particularly true, as Keynes pointed out, of financial markets, because of their inherent instability.

The case for regulation cannot be disputed, but even so, the counter-attack will certainly come. The merits of self-regulation, the salutary effects of competition, and the advantages of a "light hand" will again be rolled out in order to deflect any real attempt at disciplining market operators.

That is when our public authorities must be strong-minded, and remind themselves that is their responsibility to the public interest that demands effective regulation.

The second lesson is government involvement in the management of the economy is essential. After decades of being told the only thing we should ask of government is that it "get off our backs", we can now see it is governments - not banks or the private sector - that, as the authority of last resort, maintain the value of the currency, guarantee appropriate levels of liquidity and credit, and make irreplaceable investments in essential infrastructure.

We must not wait again until the eleventh hour before we deploy the power, responsibility and legitimacy of government to keep the economy on the right track.

The third lesson is fiscal policy, decided by governments, is more important and effective than monetary policy. We have again been told for decades that monetary policy is all that is necessary, and indeed all that is effective, both in controlling inflation and in setting the real economy on a sustainable course.

We now know that using monetary policy to ward off recession is no more effective than pushing on a piece of string and that an exclusive reliance on monetary policy to restrain inflation is just another reflection of the view - now surely discredited - that the markets always get it right.

My fourth inescapable lesson is gross imbalances in the world economy will inevitably cause it to topple off the high wire. The growing gap between rich and poor nations is bad enough, from both an economic and moral viewpoint.

But the imbalance between surplus and deficit countries is equally damaging as a strictly economic phenomenon. The surpluses drive us toward recession because they represent resources that are hoarded rather than spent, while those countries with deficits are likely, as Keynes pointed out, to try to control them through deflating their economies, thereby reinforcing the deflationary bias.

To the extent that others are willing to finance the deficits (as, for example, China's financing of the US deficit), this simply encourages uneconomic production and an excessive reliance on credit, meaning that the world economy wobbles perilously on an unsustainable foundation.

A related and fifth lesson is that the freedom to move capital at will around the world has exacted a heavy price.

The total removal of exchange controls meant that international investors could ignore and, if necessary, blackmail national governments; this became a major factor in allowing market operators to escape and defy any attempt at regulatory controls.

We have to make up our minds whether we trust accountable governments, with all their imperfections, or the unrestrained and totally irresponsible market. Our recent experience surely makes this a no-brainer.

What we now need is a new international regime, negotiated between governments, to regulate exchange rate volatility, international lending practices, and the obligations of international investors.

My final lesson is that bankers should not be trusted with the most important decisions in economic policy. No policy measure was more widely welcomed than the handing of monetary policy over to "independent" central banks.

We now have good reason to know that their decisions are not only likely to be wrong, but will certainly be self-serving - no more reliable or impartial than those of casino operators who will always set the odds in their own favour.

If we are truly to grapple with the lessons set out above, we need to restore the main decisions of economic policy, including the effective regulation of markets, to democratic control.
