latest
bloviation
on the coming
"dollar crisis"
hoping to taunt
the lady eve
into some talmudic commentary ...
====================================
" the disjunction:
The domestic macroeconomists
would typically argue
more or less like this:
Yes, the dollar is likely
to decline steeply either
when foreign central banks
stop buying dollar
denominated assets to keep
the values of their currencies
down or when international speculators
lose confidence or both.
But so what?
The fall in the value
of the dollar
will boost foreign demand
for U.S. exports.
Workers will be pulled
out of other sectors
into the export sector.
The effects of the dollar decline
are much more likely to be
a plus for employment
rather than a minus,
a boom rather than a recession.
To this, the international economists
would respond more-or-less like this:
When foreign central banks stop buying
or international speculators
lose confidence
in the value of the dollar
and thus stop buying U.S. long-term bonds
two things happen:
the value of the dollar falls,
and the rate of interest
on dollar-denominated long-term bonds spikes
The spike in long-term interest rates
discourages investment spending directly
, and also discourages consumption spending
because higher interest rates
mean lower housing
and stock prices and
thus lower consumer wealth.
The fall in domestic spending happens now.
The rise in exports
as the falling dollar makes
U.S.-made products
more attractive
to foreigners happens two years
from now
In between
a lot of people are unemployed
-and as they are unemployed,
they cut back further
on their spending.
Plus there is the risk
that the fall in the value
of the dollar
and the fall in long-term
asset prices
generated by the interest rate spike
will cause enough bankruptcies
among financial institutions
to cause a flight to quality
which will further raise
non-safe interest rates
and further discourage
investment and consumption spending
This then puzzled the domestic economists:
Why should interest rates spike?
The Federal Reserve controls
American interest rates.
If it wants to keep the price
of the ten-year Treasury bond high,
it can simply start buying bonds
until the price of ten-year Treasuries
is what the Fed wants it to be
There's no reason for employment
in construction and other
interest rate-sensitive sectors
to fall before employment
in exports and related sectors rises
at least not unless the Federal Reserve
makes a big mistake
and allows rising interest rates
to shoot the economy in the head.
And at this point the response
of the international economists fragments:
Some said that the falling dollar
would create inflation
with imports at 1/6 of GDP,
a 40% fall in the dollar would,
if fully passed through to import prices
add 6% to the U.S. price level
The Federal Reserve would feel
honor-bound to maintain
its reputation as an inflation-fighter
and so would allow interest rates
to go high enough
to produce enough unemployment
to push nominal wages
down far enough
to offset this rise in import prices
Thus the Federal Reserve
would welcome the spike
in interest rates as appropriate
and take no steps to offset it.
Others said that the adjustment
to the fall in the dollar
would require
that ten million workers shift
out of construction, retail,
and consumer services occupations
and into export and import-competing
manufacturing industries
You cannot move
ten million American workers
from one sector to another
in a matter of a year or two
without creating lots
of structural unemployment
Still others said that
financial stress would be the key:
perhaps some major Wall Street firms
would discover big unhedged risks
in their derivative books;
perhaps others would find
that the values of their portfolios
were more responsive
to changes in long term interest rates
than they had thought.
In either case,
it is financial distress
and chaos that really triggers
the recession.
And the domestic side had rebuttals
to each of these three points:
If the Federal Reserve announces now
that it is targeting
a measure of inflation
that is not grossly affected
by import prices
that it is targeting nominal wage growth
say--there is no need
for the Federal Reserve
to defend its credibility
by attacking the economy
Just as the Federal Reserve
has trained observers
that it is more important
to worry about 'core inflation'
than 'headline inflation'
so the Federal Reserve
ought to be preparing observers
to recognize that inflation
produced by rising import prices
is a one-time event
not an inflationary spiral
that needs to be fought
by triggering a deep recession
A large structural shift
will cause high unemployment
only if the transition
is quick and brutal
and only if workers
are pushed out of job-losing
rather than pulled into job-gaining sectors
Whether it is quick or gradual
and whether it is push or pull depends
once again
on the path of interest rates
Only if the Federal Reserve
fails to do its job
and allows for a massive interest rate spike
is there a problem
Financial stress
is something that can be managed:
if the Federal Reserve keeps
the path of interest rates smooth
great financial stress is unlikely
And the domestic side of the argument
pointed to the historical experience
of the U.S. from 1986-1990:
Between 1985 and 1989
the value of the U.S. dollar
declined by 40%
Between 1986 and 1990
the U.S. trade deficit
declined from 4.0% of GDP
to 0.5% of GDP
without a big recession
or
significant macroeconomic distress.
but
1986-90 began with a 50% decline
in world oil prices
a powerful stimulus
to the world economy
This time the process
is beginning with a doubling
of world oil prices
1986-90 saw Europe
growing rapidly
Europe has a high propensity
to buy U.S. exports
and the European boom meant
that U.S. exports grew much faster
in the late 1980s
than anyone had expected
This time it is Asia
that is booming
not Europe
And Asia has a relatively
low appetite for U.S. exports
The Japanese government
was willing to buy
very large amounts
of dollar-denominated assets
in the late 1980s
to keep the decline
in the value of the dollar
"orderly."
In so doing,
it inflated its domestic credit base
and touched off its own property bubble
No foreign government
is going to risk this again
just because the U.S.
would rather that the decline
in the dollar was slow and orderly.
The problem then was half
as big relative
to the size of the U.S. economy
as is the problem now
the domestic-side economists
look at the goods market
and think of a decline in the value
of the dollar as a supply shock
and as not that big a supply shock:
if half of the adjustment
in import prices is taken
in reduced margins by producers abroad
and if the shock is spread out
over four years
then 40% / 2 x 16% / 4 = 0.8%
increase in inflation relative to baseline
over three consecutive years
The Federal Reserve
could easily allow
that to happen without
providing it explained its causes well
running any risk of damaging
the credibility of its commitment
to effective price stability
No big deal
International finance economists
by contrast
look at the asset markets
. A 40% decline in the dollar
over four years
is a decline at the rate of 10% per year
Once financial markets
convince themselves
that such a decline is coming
and that they need to be compensated for it
that ought to drive a 400 basis point
wedge between U.S. and foreign
long-bond expected returns
And that is a very big deal
Martin Feldstein said
that the domestic-side economists
were keying off the past experience
of the U.S. after 1985
and of Britain after 1982,
while the international finance economists
were keying off of the experiences
of developing countries
that had run large current-account deficits
Mexico 1994, East Asia 1997, Argentina 2001.
Each side had its own preferred models
that functioned very well
at explaining
the past historical cases
that they focused on.
But there was no way
right now of settling
empirically
whether a model built
to explain the U.S.
in 1985
or Korea
in 1998
was more applicable
to the U.S.
in 2006
you had to make a bet,
either that continuities
in U.S. economic structure
were important
or that financial globalization
was important
in choosing your model
and your terms of analysis
It was very interesting
And very disturbing
Brilliant economists
thinking hard
unable to reach
even the beginnings of analytical agreement
about how to model
the distribution of possible futures"
