How low can
you go? Sometimes when spending seems weak and prices are falling there seems
to be no end to that cycle. It’s like we are staring down into a bottomless
pit. It seems like there is no end to the fall in prices. But prices never fall
without limit and the real world is a little more like the limbo than a
bottomless hole in the ground.
You remember the limbo, right? It is a calypso
thing. Two people hold the ends of a long stick and some fool with especially
rubbery legs goes under the bar as people sing limbo limbo limbo like me while
they drink tall island drinks with colorful parasols. As the bar goes lower
some of the contestants no longer can go under the bar and the game ends when
there is only one contestant who can go under the bar. For his efforts he is
usually awarded discount coupons for orthopedic surgery. Or the game ends when
your mom comes home and confiscates the rum you stole from her liquor cabinet.
The point of
this post is to raise the question of the relative efficacy of market solutions
to government intervention. After five
years we might want to question knee-jerk Keynesianism. To do this we have to
take a little venture down supply and demand lane. We will now all hold hands
and sing gumbaya.
For those
who do not want a refresher in supply and demand you may cheerfully proceed
down to the place marked “The Fun Starts
Here.”

Economists
torture their students with supply and demand to discuss everything from wart
growth to interplanetary travel. We can slap a S&D diagram on a white board
or cocktail napkin quicker than you can say diminishing marginal returns. My
friend Jimmy can wield a small hammer at limestone and produce a beautiful wall
or walkway. My hammer is my set of colored markers that I can use to explain
price and quantity changes of anything anywhere at any time.
The
invention of the stirrup revolutionized warfare and led to a rapid increase in
the price of saddles and horses.
Centuries later technological advances in computer chips led to
astronomical declines in the price per unit of power for computers. The stirrup
increased the usefulness and therefore the demand for horses and saddles and
this caused their prices to rise. Computer chip technology made it possible to
increase the supply of power at lower costs which led to declines in the price
of computer power.
Supply and
demand analysis has found its way into common discussion. Most of us are
comfortable with the idea that bad weather which ruins crop yields will reduce
supply and causes the price of tomatoes to rise. Of course when worry reduces
investor appetite for risk we talk about how the decline in the demand for
stocks causes stock prices to fall. You don’t have to be an economist to be
familiar with the use of supply and demand concepts and how they come together
to help one discuss past, present, or future expected price change. I am not
trying to say that supply and demand is as well-known as a Charlie Sheen rant,
but we have adopted this economic analysis tool to our everyday lives.
Supply and
demand analysis is a pretty remarkable thing that comes up with predictions by
making assumptions. For example, one assumption says that prices will change in
response to the condition of a market. If the main change in a market is an
increase in demand, for example, then in the absence of price change or before
a price change can take place – this creates an imbalance in the market. In
this example, we would observe demand greater than supply. This imbalance or
shortage creates the incentives for both demanders and suppliers to agree to a
higher price. In the opposite case which
finds supply much larger than demand, this surplus leads market participants to
agree to a lower price. When the price
changes in response to these market imbalances, we say that the price change
“clears the market.” Clearing of the market means that the price change brings
supply and demand back towards equality. A conclusion of the usual market model
is that prices play an important role of restoring balance to markets.
Adam Smith’s
“invisible hand” concept explained that if markets were allowed to work then we
would not need policy or policymakers or baboons to solve market imbalances. If
there is too little or too much demand for a given supply you don’t need a
committee of experts to solve the problem. What you need is a market wherein
there is strong competition, good information, no impediments preventing actors
from expressing market wishes, and no obstacles to prices changing as the
market dictates.

The Fun Starts Here
Those last
paragraphs sound like a textbook and even I am getting sleepy. But a big point
is that whether it is stirrups, tomatoes or whatever – we tend to adopt supply
and demand analysis and use it to explain and predict real world outcomes.
This is why
I am so perplexed about our application of these tools to macroeconomic
situations. While it might seem a bit
far-fetched to some of you, macroeconomists apply supply and demand to a
nation’s economy. Macroeconomists since J.M. Keynes have adopted the idea of
national demand for goods and services and policy is often directed to
stabilizing undesirable changes in aggregate demand. Accordingly, some macroeconomists
believe that part of the solution to our latest recession is downward price
adjustments. Since much of what caused the recession was a decrease in the
demand for houses and financial assets, an application of supply and demand
would argue that falling prices of houses and financial assets should part of
the solution to market balance or equilibrium. At the macro level it is interesting
that our policymakers were not content to just let Adam Smith’s invisible hand
solve the problem. Rather than believe there was some reasonable end to a game
of Macro-Limbo, they worried that prices were headed into a dark pit filled
with rattle snakes and Rush Limbaugh. To prevent prices of financial, housing,
and other assets from declining to the earth’s core, the Fed and the Treasury
bought stocks, bonds, and companies like geeks at the introduction of the
latest gadget at the Apple Store. To prevent housing prices from falling toward
the South Pole the government not only bought houses but put in a whole new
team to regulate foreclosures and to oversee an orderly disposition of houses.
Distrusting
prices to equilibrate these markets, policymakers essentially stopped the
markets from working and it appears in the end that they have drastically
slowed the movement towards a new balance. Why did policymakers behave this
way? Why did they not allow market
capitalism to function? One can only guess the reasons. One is that while they
trusted markets to work for most things on most days, they lost their trust
when it came to bigger events. Imagine if doctors decided not to use modern
medicine every time they had to treat a really serious ailment! Second, what
fun is it being in charge of a country if you don’t do anything but stand
around watching prices fall and don’t get any credit when the problem disappears?
Let’s call that the Maytag Repairman explanation. Third, perhaps they worried
that prices would not move in the right direction. But of course, housing,
bond, and stock prices did move in predictable fashion. Fourth, perhaps they
worried that prices would fall too much and create too much havoc as they fell.
It seems to me that this explains a lot of the mistrust of markets. When
policymakers faced the public with sad worried eyes they proclaimed that it was
necessary for government programs to forestall a horrible process.
Some policy
makers are bragging about recent stock prices but notice that with all the
merriment, the stock indexes are now only regaining a peak reached during the
recession and still have a long way to go before reaching highs attained before
the crisis. It has been half a decade of no real stock price growth. But with
housing prices still falling, one has to wonder if the real truth of the
intervention is that it simply stretched out the eventual adjustment. Prices
were going to fall to clear the market but the government made sure the price
change took years and years and years.
Geithner and
Bernanke would say that I am a nut job. Letting the economy free fall would
surely have caused a larger crash. But while most of my friends will agree that
I am surely a nut job, I will not agree to what we can’t know. How far would prices
have fallen and what would have been the side effects? I suspect that without government’s mucking
up expectations, prices of houses would have overshot in a downward direction
and would have made housing the bargain of the century. After all – a house has
real worth. It is composed of brick and mortar and sweat. That has value. If we
overbuilt houses for numerous years the glut would lead to prices at the low
end of that fundamental value. But clearly demand plays a role – and with
housing prices cheap enough relative to the cost of producing new houses – the
demand could come back. But we never let the prices reach those levels and we
will never know how the invisible hand might have worked.
Let’s
suppose housing or stock prices fell to these low values I proclaim above,
wouldn’t that have killed off a lot of mortgages and
created a national recession? Probably. But what I am raising here is that we
chose to pull the band aid off slowly. Are we sure that the accumulated pain of
the last five years of heavily regulated markets is not greater than the
quicker and perhaps more intense spike of pain associated with a quick pull of
the bandage? The unemployment rate has been high for quite a while and
threatens to remain there for some time. Might these unemployed have been
better off if that rate had risen even higher in 2008 or 2009 but was back to
6% today? What I do know is that it is now March of 2012 and we still hear our
leaders proclaim that they saved the day and that without further stimulus the
economy will go back into recession. I am not so sure that a market solution
could have been much worse. The recession started in the beginning of 2007 and
ended in the middle of 2009. Five years after the recession started and after
trillions of dollars of very active policy, US policymakers admit that the
economy is still too weak to be trusted. I think it is the policymakers that
can no longer be trusted.
