|A Manifesto for Economic Sense|
The economic lessons of the 1930s need not be repeated. Two of the world's leading economists say the time is ripe for a Manifesto in which mainstream economists offer the public a more evidence-based analysis of our problems. By Richard Layard and Paul Krugman.
29th June 2012 - Published by Open Democracy / www.manifestoforeconomicsense.org
More than four years after the financial crisis began, the world’s major advanced economies remain deeply depressed, in a scene all too reminiscent of the 1930s. And the reason is simple: we are relying on the same ideas that governed policy in the 1930s. These ideas, long since disproved, involve profound errors both about the causes of the crisis, its nature, and the appropriate response.
These errors have taken deep root in public consciousness and provide the public support for the excessive austerity of current fiscal policies in many countries. So the time is ripe for a Manifesto in which mainstream economists offer the public a more evidence-based analysis of our problems.
In the face of a less severe shock, monetary policy could take up the slack. But with interest rates close to zero, monetary policy - while it should do all it can - cannot do the whole job. There must of course be a medium-term plan for reducing the government deficit. But if this is too front-loaded it can easily be self-defeating by aborting the recovery. A key priority now is to reduce unemployment, before it becomes endemic, making recovery and future deficit reduction even more difficult.
How do those who support present policies answer the argument we have just made? They use two quite different arguments in support of their case.
The confidence argument. Their first argument is that government deficits will raise interest rates and thus prevent recovery. By contrast, they argue, austerity will increase confidence and thus encourage recovery.
But there is no evidence at all in favour of this argument. First, despite exceptionally high deficits, interest rates today are unprecedentedly low in all major countries where there is a normally functioning central bank. This is true even in Japan where the government debt now exceeds 200% of annual GDP; and past downgrades by the rating agencies here have had no effect on Japanese interest rates. Interest rates are only high in some Euro countries, because the ECB is not allowed to act as lender of last resort to the government. Elsewhere the central bank can always, if needed, fund the deficit, leaving the bond market unaffected.
Moreover past experience includes no relevant case where budget cuts have actually generated increased economic activity. The IMF has studied 173 cases of budget cuts in individual countries and found that the consistent result is economic contraction. In the handful of cases in which fiscal consolidation was followed by growth, the main channels were a currency depreciation against a strong world market, not a current possibility. The lesson of the IMF’s study is clear - budget cuts retard recovery. And that is what is happening now - the countries with the biggest budget cuts have experienced the biggest falls in output.
For the truth is, as we can now see, that budget cuts do not inspire business confidence. Companies will only invest when they can foresee enough customers with enough income to spend. Austerity discourages investment.
So there is massive evidence against the confidence argument; all the alleged evidence in favor of the doctrine has evaporated on closer examination.
The structural argument. A second argument against expanding demand is that output is in fact constrained on the supply side - by structural imbalances. If this theory were right, however, at least some parts of our economies ought to be at full stretch, and so should some occupations. But in most countries that is just not the case. Every major sector of our economies is struggling, and every occupation has higher unemployment than usual. So the problem must be a general lack of spending and demand.
In the 1930s the same structural argument was used against proactive spending policies in the U.S. But as spending rose between 1940 and 1942, output rose by 20%. So the problem in the 1930s, as now, was a shortage of demand not of supply.
As a result of their mistaken ideas, many Western policy-makers are inflicting massive suffering on their peoples. But the ideas they espouse about how to handle recessions were rejected by nearly all economists after the disasters of the 1930s, and for the following forty years or so the West enjoyed an unparalleled period of economic stability and low unemployment. It is tragic that in recent years the old ideas have again taken root. But we can no longer accept a situation where mistaken fears of higher interest rates weigh more highly with policy-makers than the horrors of mass unemployment.
Better policies will differ between countries and need detailed debate. But they must be based on a correct analysis of the problem. We therefore urge all economists and others who agree with the broad thrust of this Manifesto to register their agreement at www.manifestoforeconomicsense.org, and to publically argue the case for a sounder approach. The whole world suffers when men and women are silent about what they know is wrong.
