Central Banking (Quarterly Journal vol XIII no 4
On the 20th March, a new Governor of the Bank of Japan took over. The previous
incumbent's tour of duty was marked by economic stagnation. This can be seen
either as an example of policy failure, or of the limits of central banking
power. After the debates of the last 50 years, it has become generally agreed
that central banks can satisfactorily manage economies which are prone to inflation;
what remains to be decided is whether economies can also be managed under conditions
of deflation.
The retired Governor, Masaru Hayami, has repeatedly claimed that central banks
are powerless to stimulate demand in the conditions in which Japan has found
itself. But he is not an unbiased observer. Furthermore, he never seemed to
have sufficient confidence in his view to test it by prolonged and rapid quantitative
easing, which is the policy measure advocated by those optimists who believe
that central banks can create recovery despite deflation.
Quantitative easing requires rapid expansion of the monetary base and, while
there have been periods in which this has occurred, they have been relatively
brief and they have not been sustained. As Chart 1 shows, Japan's base money
rose rapidly from August 2001 to April 2002 but, on a seasonally adjusted basis,
there has been barely any growth since then.
The failure to try quantitative sustained easing does not of course prove
that it would have been successful; it just leaves the question open. This
is unfortunate on two grounds. First, the policy might have succeeded, thereby
avoiding the pain and waste of resources which has been Japan's sad experience
in recent years. Second, if it had been tried and had failed, it would have
opened a debate on the need for new policies. As it is, policy is indecisive
while the debate remains unsettled.
The real opposition to a more aggressive policy of monetary easing does not
come, of course, from those who fear that it would fail, but from those who
fear it would succeed. There is little opposition to policies whose opponents
are truly convinced that they will fail and thus justify their intellectual
position, unless they can argue that such policies will do harm in the process
of failing. Such claims have only been advanced rarely and half-heartedly.
The constituency which fears success has several different members. It contains,
among others, those who hold views and recommend policies, which are at odds
with the mainstream economics.
There are, for example, those who recommend cutting back capacity, as a way
to encourage recovery, while mainstream economists recommend, when economies
are operating below full capacity, that demand should be stimulated. The apparent
alternative of cutting back capacity is seen as both ineffective and wasteful.
It is ineffective because cuts in capacity are accompanied by cuts in employment,
which reduce demand and leave the problem of surplus capacity unresolved, while
adding to the evils of unemployment.
Holders of such views would be disappointed if demand was stimulated and the
economy then recovered. This is partly because they dislike the idea of being
proved wrong, but in many cases it is also because they seem to have a political
as well as an economic agenda. They appear fearful that economic recovery by
orthodox means will remove the pressure for political and social changes which
they would like to see.
Another group is concerned that monetary ease will not only end deflation,
but that it will usher in a period of inflation. Some dislike the idea of any
inflation and others fear that it would be hard to control.
Finally, there are those who, correctly in my view, see monetary ease as leading
directly to a weaker exchange rate and fear, I hope wrongly, that the resulting
rise in Japan's current account surplus will lead to international trouble
and ill will.
The fundamental problem for Japan is that it naturally generates more savings
than it can profitably absorb in its own economy. It needs, therefore, to export
these excess savings and this can only happen if the external current account
surplus rises, as the export of capital and the external surplus are one and
the same thing.
The scale of the problem is, however, very large. There are two serious elements
of disequilibrium in the way the economy is currently operating. They are the
budget deficit and the level of investment.
The former is running at 8% of GDP and must ultimately fall by a large amount.
The fall needed in the latter is of similar proportions. Japan invests a much
higher proportion of its GDP than other developed countries, but its potential
growth is much less. This combination is unstable and, since growth is limited
by Japan's demography, investment must fall.
Not only has Japan had, for many years, one of the lowest birth rates in the
world, but also it has had virtually no immigration. As a result its workforce
is falling. Whereas the number of those of working age in the US will probably
rise by around 1.5% p.a. over the next decade, the numbers in Japan will fall
by around 0.5% p.a., unless there is a major change in immigration policy.
As a result it is virtually certain that the US will grow much more rapidly
than Japan. The only alternative would be for Japan to improve its labour productivity
much faster than America. In recent years there has been a difference between
the rate at which productivity has changed in the two countries, but it has
been in favour of the US rather than Japan.
If, just for illustration, it is assumed that both countries will improve
their labour productivity by 2% p.a., then the rate of growth of the US will
be around 3.5% p.a. and that of Japan around 1.5%. The impact of population
growth is so large that even if we alter the assumptions in Japan's favour,
it is unlikely that the US will not grow at least twice as fast as Japan.
If Japan grows at half the US rate, it must spend much less on new capital
or the return on that investment will be extremely poor. At the moment Japan
invests much more of its GDP than the US. Even if public sector spending is
ignored, as being an area where poor profitability is unimportant, the level
of Japanese investment is clearly excessive. Capital spending by the private
sector is 4 percentage points of GDP higher in Japan than in the US and, if
the investment in Japan is to be profitable, it must fall to a much lower level
than the US to compensate for the much lower rate of potential growth.
To get the economy into equilibrium, therefore, there must be large falls
both in Japan's budget deficit and its investment ratio. For this to occur
without economic catastrophe there must be a large compensating rise in demand
from elsewhere in the economy. There are only two places from which this can
come. One is domestic consumption and the other is net exports. If it is to
be the latter, there will have to be a large rise in Japan's current account
surplus.
In practice, a rise in exports will have to provide at least the major part
of the extra demand that is required. This is because there will not be a natural
reduction in the savings of the Japanese people until some years have passed.
The fall in the birth rate, which is already causing a decline in the workforce,
did not begin till some time after the Second World War had ended, as Japan's
baby boom came later than it did in Europe or America. The result is that Japan
has a proportionately large number of people in their fifties, it being 50
years or so after the baby boom, and there are also lots of people in their
late twenties, who are the baby boomers' children.
These groups need to save for their retirement and the elder group are typically
in the high savings age, when their children have left home and they are through
the expense of university. If the present generation of workers do not have
high savings, they will be unable to support themselves in retirement. In ten
to fifteen years the working population will have fallen sharply and the number
of retired will have risen. The latter will have to generate enough savings
to support themselves when they have ceased to work, as a massive and unsustainable
burden will otherwise fall on the shrunken workforce.
But while the current generation need to save, they cannot expect these savings
to be profitably invested at home and if they are invested unprofitably, savings
will have to be even higher. Japan is thus faced with a dilemma; she must either
alter her population structure by massive immigration, or lower her exchange
rate so that she can generate a large increase in her current account surplus.
This dilemma is not an easy one. Massive immigration is a most unpopular idea
in Tokyo and a large current account surplus is disliked in Washington and
Brussels. So far the typical response has been one of denial. Because neither
solution is acceptable, many prefer to deny the existence of the problem.
It is helpful here to compare this with the situation in Europe, which faces
a similar, though less acute, choice. Europe has a potential escape route,
which is not open to Japan, in that a large proportion of its population of
working age are not employed. Changes in labour laws and practices are thus
a solution to Europe's problem that is not available in Japan. As the current
debate in Germany over reform of the labour market is showing, however, denial
is as common in Europe as it is in Japan and the resistance to change is fierce.
As denial is such a common response to Japan's problems, it is sadly far from
certain that the correct policy measures to deal with them will soon be implemented.
It is therefore sensible to consider two things. First, what measures should
ideally be introduced and second, what is likely to happen in practice.
With regard to the correct policy measures, I am strongly in agreement with
the authors of two recent articles in Central Banking, Tim Congdon and Richard
Werner. Both of them have argued, in my view correctly, that the best way forward
for Japan is to use monetary rather than fiscal policy to stimulate demand
and to aim to expand money supply directly, rather than indirectly through
an expansion of the monetary base. Although there may be marginal differences
in the approach recommended by each of us, the basic thrust of our arguments
is in each case the same.
Monetary base expansion is recommended on the grounds that it will lead, in
time, to expansion of the broad money and that will in turn lead to economic
recovery. It is, however, agreed that step one of this process does not necessarily
lead quickly to an acceleration in money supply. Those of us who favour a change
in funding policy argue that it will achieve broad money growth more surely
and quickly than can be achieved by the actions of the central bank.1
The route by which a change in funding policy would lead to a surer and more
rapid rise in money supply than can be achieved through quantitative easing
can be explained in several different ways. It can be seen, for example, as
a way to reduce the risks run by the banking system. Increases in the commercial
banks' holding of government debts, will cause money supply to rise. If the
banks buy bonds, however, they will have the risk of interest rates rising.
If the government issues only Treasury bills, or borrows directly from the
banks on an overdraft type basis, the banks will not have such risks. If banks
have a profitable and riskless outlet for lending then they will be naturally
willing to expand such assets rapidly and, this will increase money supply.
In practical terms, however, this policy is unlikely to be implemented in
the near future, despite the fact that it was supported by the then Vice-Minister
of the Ministry of Finance Haruhiko Kuroda, who set out his views in a talk
he gave to a meeting of the US National Bureau of Economic Research that was
held in Tokyo in September, 2002. At the moment, the best policy that can reasonably
be expected by Japan's well wishers is that the new team at the Bank of Japan
will revert to the policy of monetary base expansion that was briefly in place
from August 2001 to April 2002. In an interview in this journal in August 2002
Milton Friedman argued that such a course of action would be successful, in
time, provided that it was vigorously pursued for a prolonged period.
While I have greater confidence in a policy which would directly expand the
monetary aggregates, an attempt to create recovery through monetary base expansion
has two virtues. First it might succeed. Second it will be difficult to obtain
agreement for the less familar policies that Tim Congdon, Richard Werner and
I have recommended, until the relative orthodox approach of quantitative easing
has been tried.
1Any reader who wishes to look at my own version of
this, can read the English version of an article I wrote for the Japanese journal
Genron in September 2001, which is also available from the Smithers & Co website.
