The weakness of the world's economy is neither unusual nor necessarily very serious.
Recessions, and a speedy recovery from them, are normal. The worry today is
that the policy response is inadequate.
World demand has been supported by low savings in the US and the UK and rising
budget deficits. Despite this, growth has slowed to well below its trend rate,
as rising unemployment and falling capacity utilisation show. Profits rise
when growth is above trend and fall when it's below. We should therefore expect
profits to fall this year. Profits drive economies. As they fall, companies
cut back on investment and employment. If disappointment hits the stock market
and unemployment weakens house prices, then households will increase their
savings rate and add to economic problems. Below trend growth thus leads to
decline, unless reversed by a change in economic policy.
With excess capacity and falling profits, investment is highly unlikely to
increase. If, as seems likely, household savings in America and Britain now
rise, and there is no compensating fall elsewhere, then budget deficits must
rise again. They can, however, rise either deliberately in order to prevent
a recession, or accidentally because there is one.
The opposition to higher budget deficits has mounted in Europe, Japan and
America. This is unfortunate, but not entirely unreasonable. Japan provides
a worrying example of the apparent failure of fiscal policy. A decade of stagnation
since 1992 has accompanied a swing in the budget balance from a surplus of
0.8% of GDP to a deficit of 8%.
This failure may have been caused by the offsetting impact on external trade.
The yen has strengthened and the trade surplus fallen from $125 bn. in 1992
to $ 70 bn. in 2001. This reaction is forecast by several economic models.
They show that, in the absence of additional monetary stimulus, rising budget
deficits push up the real exchange rate.
Therefore Japan's fiscal policy has not been ineffective. It has just failed
to benefit Japan. Demand in the rest of the world has been aided by the fall
in Japan's external trade surplus. We are left with a paradox, which may have
been accentuated by globalisation. Rising fiscal deficits are just what the
world needs, but they are a disinterested kindness, done for the benefit of
others.
It is unlikely that America, Europe and Japan can be persuaded to increase
budget deficits for their mutual benefit. It is more likely that the "Stupidity
and Gloom Pact" will act to offset the small stimulus from tax cuts that
President Bush is proposing; though the unselfish nature of his actions may
have escaped his notice.
Monetary policy is thus the only way that world demand is likely to be boosted.
Economic forecasting is so uncertain that it may not prove necessary. But policy
must always be a matter of judgement and, although the case for greater monetary
ease has long seemed overwhelming, it has been opposed by the ECB and the Bank
of Japan.
Policies, however, change. The Bank of Japan will have a new governor soon
and events will influence even the Europeans. Nonetheless, the chances of a
double dip world recession must be high.
Once interest rates reach zero, they can be cut no further and monetary stimulus
depends on less orthodox measures. Here lies the rub. Few are comfortable with
heterodoxy. This inhibits vigorous action not only when rates reach zero, but
also as they approach it. Monetary policy does not need to become ineffective
when nominal interest rates are very low, but it tends to be weaker in practice.
Central banks, including the Fed, have been less aggressive in the post- bubble
world than they should have been. It may therefore take time for monetary policy
to catch up with today's needs and, even then, its impact will be delayed.
President Bush seeks re-election in November 2004. He should be pleading with
the Fed to pull out all the stops now. A call for co-ordinated worldwide fiscal
stimulus would also show statesmanship, even though its success is improbable.
