The
Deflation Dragon is roaring and Keynesians are licking their chops. Like those
who promote fad diets and weight loss pills, Keynesians are appealing to your
inner anxiety and love of easy solutions rather than telling you the truth
about what ails the world economy. A typical article on this topic is one that
appeared at Bloomberg.com last week -- http://www.bloomberg.com/news/2014-10-22/currency-wars-evolve-with-goal-of-avoiding-deflation.html
This Bloomberg article
does a few things. First it does a nice job of reporting deflation
changes in various spots around the world. There is plenty of it. I have no
argument there. Second, it connects exchange rate depreciation wars with these
deflation occurrences. Finally the article concludes that if exchange rate
depreciations will not successfully end deadly deflations, then we should deal
with it with “whatever means is necessary.”
Clearly more
people are coming to the conclusion that widespread deflation needs to be
reckoned with and that typical Keynesian approaches that boost aggregate demand
must be administered. These approaches include depreciating your exchange rate,
goosing money and credit, and having larger government deficits and debt.
The
intuition is simple but deceptive. Draw a supply and demand curve diagram. Shift
the demand curve downward. Notice the resulting lower equilibrium price. Now
shift the demand curve rightward. Viola – the equilibrium price rises back to
normal. Furthermore, equilibrium output (and presumably employment) increases.
QED. Demand is the problem. The problem is evidenced by deflation or falling
prices. The problem is rectified by increasing demand. Don’t you just love
economics! Now I can drink my JD and spend the rest of the day watching leaves
fall.
I agree with
the whole Supply and Demand story but disagree with how the world can best push
that lagging Demand Curve back to a better position. Conventional Keynesian wisdom reflexively
wants the government to manage the Demand Curve through exchange rate,
monetary, and fiscal policies. But in 2015 world economic problems require a
very different potion. Even the master of all this theory – J.M. Keynes, if
alive today would have looked at today’s situation and balked at the
traditional Keynesian remedies.
Why would
Keynes balk with Keynesianisms? Because Keynes lucidly and powerfully expressed
the idea that confidence and fear were important motivators. When writing about
the Great Depression it was Keynes who explained that monetary policy would be
like “pushing on a string.” This meant you could push money into the system but
because of lacking confidence, banks or firms or households would simply hold
onto the money. They would save or hoard it. They would not spend it. He called
that “the liquidity trap.”
So Keynes
established why fear made monetary policy ineffective. Living today and seeing
how governments have backed themselves into huge debt corners, he might also
conclude that fiscal policy won't work in an environment where governments
were defaulting on debt. I am not sure what Keynes would say today about
exchange rate policy but such policy is not one that every country can employ.
This is a zero-sum game. If one country depreciates its currency to stimulate
demand for its products, then another country has to endure an appreciation and
a reduction in demand for its goods and services. Already the US is getting
unhappy with Japan and other countries that are making gains at US expense.
Larry you
are so depressing! I am not. I am fun! There is a solution to deflation but it
involves not calling the 800 number for another fast acting pill. Think about what
most countries have been through in the last years. Think about the real credit
and financial problems faced by household, firms, and governments. It might
sound humane and nice to tell US families that they can now borrow 97% of the
price of a new house with less stringent income requirements. But surely all
those stories about under-water mortgages are still fresh enough to make
potential home buyers know that this is not an attractive option. Basically it is snake oil.
The solution
is the same one the doctor gives to the patient undergoing rehab. Keep at it.
Keep doing those exercises and someday you will regain better use of that limb.
There is no easy way. There is no pill or diet. Just keep sweating and grunting
and pushing to get stronger.
Today the
sweating and grunting has a lot to do with reducing previous levels of debt
among households, firms and governments. Either under- or over-regulation of
what the IMF calls legacy problems are also part of the problem of uncertainty
and insufficient demand. Under-regulation means that governments should do more
to clear up financial, housing, and other problems. Over-regulation means they
have done too much and have handicapped the very patients doing the rehab. Do
those exercises with a 100 pound sack of potatoes on your back!
Nutshell.
Deflation does exist and is a challenge. Aggregate demand is deficient in many
places and needs to be prodded upward. Aggregate demand will only be worsened
by policies that do not address fundamental problems. Most Keynesian remedies fall
into that category. Policies that are tough but will make us stronger are what
we need. We need to cleanup debt. We need to give workers and companies
stronger incentives and remove impediments to work, innovate, and produce. The IMF pays lip service to
such “restructuring” policies but alas in the real world the snake oil salesman
seems to have more influence.
