AS THE ECONOMY TURNS
EVEN THE DEUS EX MACHINA DIDN’T MAKE HOUSE
CALLS

In the classical Greek theater impossible situations were
sometimes resolved by having a god descend upon the stage to set events on the playwright’s
intended course. They literally brought
the god onto the stage with some combination of pulleys and lifts and this part
of the story came to be known as the deus
ex machina, which translates into the “god from the machine” if I remember
my Latin. The Greek god could do
anything and was a convenient tool that could right any wrong or destroy any
fortress. We would assert that basic
problem with American medicine today is that too many people are looking for somebody
to play the role of the Greek god in the tragedy of attempting to pay for our
medical services.
Americans spent 1.52 trillion dollars on health care in the last
12 month reporting period, October 2004 to September 2005 and that represented
12.1 percent of our 12.6 trillion dollar economy [SOURCE: www.bea.doc.gov/bea/newsrelarchive/2005/gdp305a.xls]. And while the increasing cost of health
care is often in the news, the BUREAU OF LABOR STATISTICS (BLS) reported that
the price of health care only increased 4.1 percent over the last 12 months,
compared to the average inflation rate in the economy of 4.3 percent, as
measured by changes in the Consumer Price Index (CPI). Somehow I suspect that the fact that health
care costs ran below the average in the past year is a bit of an aberration,
especially since every aspect of health care costs has run well ahead of the
CPI when we look at what has happened over the last 22 years. On the average,
since the 1982-84 BASE YEAR period, over-all prices as measured by the CPI have
almost doubled (from 100 to 199.2), while most medical care prices have about
tripled (MEDICAL CARE from 100 to 326.2; MEDICAL CARE COMMODITIES from 100 to
278.9; MEDICAL CARE SERVICES from 100 to 339.7; PROFESSIONAL SERVICES from 100
to 284.0;) and HOSPITAL AND RELATED SERVICES have more than quadrupled. from
100 to 443.6 [SOURCE: <http://www.bls.gov/news.release/cpi.t01.htm>].
With the increase in the prices has come the usual impatient American
demand that the government “do something” about the rising costs, as if the
government had the ability to roll back the laws of supply and demand, the laws
that determine most of the prices in our capitalist system. If we look more closely at the evidence we’ll
see that these price increases are probably caused by increases in the DEMAND
for health care. The logic is
simple. There are only two events that
can cause prices to rise in a competitive market, either we have a DECREASE IN
SUPPLY or we have an INCREASE IN DEMAND.
If we consider the cause of the higher prices to be a decrease in
supply, what we are saying is that health care suppliers would have been
reducing the quantity of health care they offer to consumers even if the price
had stayed the same. This would be
consistent with some of the media stories about the big bad drug companies
holding back their supplies in order to raise their prices and increase their
profits. However, a reduction in supply
assumes that consumers would continue to want the same amount of the product
until the price begins to change. This
would give us a short-term situation in which suppliers were supplying less than
they were earlier and consumers were continuing to want the same old quantity. Economists would call this a SHORTAGE, where
the quantity that consumers wanted to buy was more than the quantity that
sellers were willing to sell at the old price. If we had had a shortage develop
in this manner, then either the price would have risen or health care providers
would have had to ration their products.
While the higher prices are certainly consistent with what we have seen
in health care prices there is another problem.
In this scenario we would also be seeing consumers buying less, because
of the higher prices or rationing, and that is not consistent with the world
that we know, since the volume of health care we consume today is greater than
at any time in the past. These
conclusions are inconsistent with the facts, so the hypothesis that the higher
prices over the last twenty odd years have been caused by any kind of supply
reduction is logically false...
The alternative hypothesis is that the higher prices have been
caused by an increase in demand. When a
market experiences an increase in demand we have a situation in which consumers
want to buy more even if the price does not change but, in the absence of a
price change, suppliers are content to continue to deliver the same volume of
services to the marketplace. Since we
would normally assume that we were starting out with a market in balance
between demand and supply, the change would again cause a shortage just like we
discussed a moment ago, only this time it was the change in buyer behavior that
was the cause. One remarkable feature of
markets is that it usually does not matter whether a shortage was caused by a
change in supply or by a change in demand; the effect of a shortage is either
for the price to rise or for some sort of rationing to develop. However, now the higher prices would cause
the sellers to increase their production from whatever it was earlier to
whatever is most profitable at the new higher prices. If we have a procedure that a hospital can
perform at a cost of $500,000 and the market price is only $100,000 the
hospital may not be able to provide the procedure, even if it is
life-saving. If the market price changes
to $700,000 the hospital will not only provide the procedure, it will promote
it. An increase in demand leads to both
higher prices and higher quantities and this is consistent with the data from
the world that we know.
A final, technical point here is that it is quite possible that
both supply and demand have been changing over the last 22 years. As a matter of fact, it would be a surprise
if that were not true. What we have
shown above is that the dominant force behind the price increases has been
rising demand rather than falling supply.
Actually, once we have shown that rising demand is the dominant factor we
have to allow that we know nothing at all about the direction of supply change
without much more sophisticated analysis.
Changes in both demand and supply have had some role in getting us to
the point we are right now in health care.
So where has the increase in demand come from? The first logical cause has been our higher
incomes. Health care is a NORMAL GOOD,
which means that the demand for health care has increased, and will continue to
increase as long as incomes continue to increase. As incomes go up, people often try to buy
more and better health care with some of their increases in income. And just like the market for stringbeans,
once you get an increase in demand, the price goes up too. If we really wanted to put a lid on health
care costs the most obvious solution would be to stop our increases in incomes
but I doubt that anyone, other than a handful of Luddites, would want to use
this approach. Since we are fortunate
enough to live in a society in which increases in income are so common as to be
expected, we should recognize that the demand for health care, and health care
prices, will continue to rise.
Of course, there are many other causes for this rising
demand. Many of the ailments that our
parents and grandparents were expected to “put up with” or worse, die because
of, are treatable or even curable in today’s medical environment. These advances in medicine result in a
two-pronged increase in demand. Consider
something as simple as the flu shot. The
great flu epidemic of 1918 killed over 20 million world-wide, including 675,000
Americans [SOURCE: < http://www.stanford.edu/group/virus/uda/
>]. While the specter of Bird Flu looms on today’s horizon, modern medicine
has the ability to reduce most flu epidemics to mere inconveniences to most
people. Today we have demand for some
products that did not exist in earlier times, even if the earlier time was just
a year or two back in the distant medical past.
So we have a market for medical services in which we have a rising
demand and consumers upset about rising prices.
Is it time to bring in the deus ex
govenmenta to descend upon the stage to set events on our intended
course? That depends, to a very large
extent, on what you think the government is capable of doing. Most economists recognize that there are two
necessary conditions that must be met before the government can play a
constructive role. There has to be a
problem and the government has to have the ability to alleviate the
problem. Unless both conditions are met
there is no logical basis for the government to be on the stage of health care.
High prices play a dual role in this drama. They are the villain when they ascend to
“unfair” levels. And they provide the
profits which draw more resources to the industry. Unfortunately, the two roles are opposed to
one another. If we allow the prices to
continue to rise at recent rates, more and more of our fellow Americans will be
priced out of the medical care market.
On the other hand, if we don’t allow the prices to rise, then the
profits will not be there to attract new resources, including new medicines and
new people. We can’t have it both ways,
so we must say that one is the OPPORTUNITY COST of the other.
Of course, we could have the government produce our medical care. Imagine that, the people who brought us FEMA
in charge of your life or death. That’s
pretty scary. Any takers?
Alternatively, some people would say we should have some sort of
national health care like they do in all of the other modern economies in the
world. What people do not realize is
that you cannot repeal the laws of supply and demand. Even if I walk into a
drugstore and get my medicine for “free” somebody paid for it, and in the other
countries it is the taxpayer, sometimes on a Medicare type assessment and
sometimes out of total tax revenue. We
could do that, but that kind of program raises costs for everyone on everything
as the taxes impact the other markets.
All we would need is about a trillion dollar tax increase to pay for
it. Anyone interested? I didn’t think so. Sometimes there are not any simple
solutions. Just don’t wait for the deus ex machina to come and help. He never did make house calls, even for the
Greeks.
