Statement of
Alan Greenspan
Chairman
Board of Governors of the Federal Reserve System
before the
National Bipartisan Commission
on the Future of Medicare
April 20,1998

Messrs

Chairmen and members of the Commission, I am pleased

to be here today and encouraged that the President and the
Congress are undertaking a fundamental reassessment of the
Medicare program

Since Medicare was established more than

thirty years ago, it has provided the elderly with access to
medical care

But the growth of Medicare outlays has continued

to outstrip the growth of the rest of the federal budget, and
we've been able to avert a full-blown financing crisis only
through a series of marginal adjustments to the program

As you

well know, the pressures will become increasingly intense as the
baby boomers start to retire around the end of the next decade
The challenge of adapting Medicare to meet our long-run
needs is formidable and will require difficult choices
could be costly

Delay

Action now would give all parties greater

opportunity to adjust to a revamped program and would limit the
severity of the possible dislocations that could result
You will be hearing from health experts who will offer
detailed information on Medicare options

You will also be

considering how the burden of financing the elderly's medical
care should be split between the government--and thus funded by
taxpayers--and the elderly themselves

But, at a more

fundamental level, you must address the basic question of how
much our nation is willing to expend for the ever-increasing
capabilities of medicine and, in the process, how we allocate the
economy's scarce resources between Medicare and our many other
competing needs
remarks today

These latter issues will be the subject of my

2
In some ways, health care is like any other good or service,
and, in the absence of regulation, the share of consumer income
going to medical care would reflect the trade-off of choices
against other consumer desires

That share will vary from

individual to individual depending on their incomes and their
need for medical care

There is no predetermined share of income

that should, in any abstract sense, be devoted to health care-either for an individual or for an economy as a whole--and an
increasing share, or for that matter, a decreasing share, in
itself, need not indicate a problem
For most goods or services, prices reflect both the cost of
the resources used to produce that good or service and the value
of that good or service to consumers

Thus, prices are vital in

the allocation of resources to their highest value uses
the process that maximizes standards of living

That is

Households

purchase most products directly from their income and assets
But some outlays, such as those to repair or replace a home
damaged by fire, are potentially too large and uncertain to
easily budget

Under such circumstances, individuals can gain

from pooling their risks through private insurance
Medical care has increasingly fallen into that category as
costs have swelled

Clearly, individuals benefit from having

insurance because it relieves them of concern about the
possibility of devastating medical expenses

But, as is its

purpose, insurance reduces individuals' sensitivity to the total
underlying economic cost of care

Because individuals do not pay

3
the full incremental cost of services covered by insurance, they
have less incentive to restrain the use of medical care and the
adoption of technologies that divert resources from other highly
valued nonmedical goods and services

Indeed, there is a

tendency for the insured to seek any medical service expected to
offer at least some benefit, regardless of its cost in real
resources

It also is probable that this system supports the

development of more new technology and greater diffusion of
existing technology than would be the case were all medical care
purchased directly from family resources

Such behavior is a

manifestation of so-called "moral hazard," which is a
characteristic of virtually all insurance markets

Of course,

the private insurance system, reflecting the supply and demand
for medical services, will adjust prices, that is premiums, to
cover costs
But, as medical costs have risen, they have exerted pressure
on profit margins of businesses and indirectly on real wages of
workers

Presumably in response, we have witnessed considerable

innovation in recent years in private markets for medical
insurance in an endeavor to contain inefficiencies and excess
costs

The rapid expansion of managed care, in its many forms,

is the clearest evidence of these efforts
In the public sector, Medicare was initially designed to
supply the elderly with insurance coverage similar in structure
and scope to that enjoyed by the non-elderly population
Clearly, it remains an exceptionally popular program, but it has

4
not kept pace with changes in the private health care system
Unlike the market-driven private insurance system, cost pressures
in Medicare are reflected mainly in the federal budget

There

are no automatic signals such as those that balance supply and
demand for medical care in the private sector

Hence, in

managing Medicare, we must be particularly sensitive to the fact
that, like any product, medical care is produced ultimately by
the work of individuals, and the more human effort that is
expended to provide medical care, the less effort that is
available for making other highly valued products
Thus, a key question confronting this Commission is whether
the current stance of public policy, lacking a market test, is
altering medical demand in a way that distorts economic choices
and lowers overall productivity and standards of living

If

Medicare is to be sustained as a viable program, it is important
that this question ultimately be answered in the negative
If the answer is ambiguous, or in the affirmative, the
Commission may wish to recommend that the Medicare program be
reshaped in a way that would encourage beneficiaries and medical
providers to make more cost-effective decisions than many do now
If successful, this approach would reduce the resources used per
unit of health care produced, presumably lower overall health
care expenditure growth from an unsustainable trajectory, and
help ensure continued access to affordable care for Medicare
beneficiaries
As I noted, the private medical marketplace has been moving

5
rapidly in this direction in recent years

The adjustments have

not always gone smoothly, but institutions, acting on behalf of
individuals, are increasingly confronting the trade-offs between
the consumption of health care and the consumption of other goods
and services

That process may have received a push in 1989 when

the Financial Accounting Standards Board circulated a draft rule
to require companies to record future contingent medical costs
for retirees on their balance sheets and make appropriate charges
against current/ income

That rule was subsequently adopted and,

perhaps by happenstance, roughly coincided with the onset of a
major effort by American businesses to contain medical costs for
all workers
In any event, much of the working-age population now belongs
to health plans that actively manage care in order to hold down
costs

In part, this is accomplished by offering incentives to

providers to practice cost-effective medicine

For example, we

are seeing a closer scrutinizing of services delivered by highly
paid medical specialists, some of whom have experienced a decline
in compensation in recent years
It is regrettable, but probably inevitable, that moving from
an unconstrained fee-for-service system to a more cost-effective
one is perceived by some patients as a major reduction in the
quality of care

While the extent is arguable, any shift away

from nearly unlimited use of even only marginally beneficial
procedures will be seen as a reduction in quality, irrespective
of the size of the savings of real resources devoted to that

6
marginal increment of care

There is always one more test that

will reduce the risk, however infinitesimal, of a misdiagnosis.
Businesses' efforts to rein in payments for health insurance
are also forcing employees to think more about the trade-offs
between additional company-financed medical insurance and higher
wages
These developments have helped stem the uptrend in the share
of GDP going to health care, which caused so much concern just a
few years ago

Nonetheless, Americans still devote a far higher

share of GDP to medical care than does any other major industrial
country

In the past few years, medical costs have amounted to

about 13-1/2 percent of our GDP, compared, for example, with
about 10 percent for Germany and France and about 7 percent for
Japan, Sweden, and the United Kingdom
From an accounting perspective, the difference between the
percentage of GDP that we devote to health care and the
percentage in Germany or France appears to reflect mainly our
higher pay for doctors and other medical practitioners relative
to the average wage in the economy and our measured higher
administrative costs

It is difficult to obtain comparable net

administrative cost estimates because our system includes a
closer monitoring of costs by private insurers, which presumably
reduces other costs

Among the industrial countries that devote

the lower shares of GDP to health spending, the health share in
the U K , for example, is further depressed relative to ours by
fewer doctors per capita and less high-tech equipment

Almost

7
certainly, our system produces the most sophisticated, and
perhaps the highest quality, medical care in the world

But we

have little evidence that, as a result, our population is any
healthier, on average, than those populations that devote fewer
resources to health care, recognizing, of course, that health
outcomes depend on a host of other influences in addition to the
level of medical expenditures
Whether the share of our GDP going to medical care will
remain flat over the next few years--or whether it will start
rising again--is uncertain

But it almost surely will increase

as the baby boomers move into the age brackets in which medical
costs tend to accelerate

Indeed, on average, medical outlays

for persons aged 65 and over are nearly four times the size of
those for persons aged 19 to 64 and roughly seven times those for
persons under age 19

Currently, 12-1/2 percent of the U S

population is age 65 or older

This share is not much greater

than it was twenty years ago, indicating that aging alone has
played a relatively minor role in explaining the growth in
aggregate health spending over the past two decades

But, by

2030, shortly after the last of the baby boomers has turned 65,
the elderly are expected to account for about a fifth of the
population

A simple calculation suggests that, all else being

equal, the projected change in the age distribution of the
population over the next thirty years will add nearly 2 0 percent
to the level of health care spending
Demographics aside, the trajectory of health spending in

8
coming years will depend importantly on the course of technology,
which has been a key driver of per-person health costs

To be

sure, technological innovation improves the quality of medical
care, but its effects on overall costs are not always clear-cut
Technological innovation can decrease the cost of a given course
of treatment and thus has the potential to reduce overall costs
But it also can expand the range of treatment options, with the
potential of adding to overall costs

Advances in arthroscopic

surgery, for example, have greatly reduced the cost and
difficulty of repairing many kinds of knee damage, but the new
techniques doubtless have contributed to the enormous increase in
the number of knee surgeries that are performed each year
The future path of medical, indeed all, technology is
exceptionally difficult to forecast

Many effective new

technologies result from synergies of two or more previously
developed technologies

Remarkably, when the laser was invented

about forty years ago, lawyers at Bell Labs reportedly did not
rush to seek patents because they thought it had little bearing
on Bell System interests

In fact, its full potential could not

be realized until the development of fiber optics, and the
synergy of the two is one of the most powerful and versatile
advances in telecommunications technology in the twentieth
century

Examples in medicine abound as well

For instance,

organ transplantation was a huge technological advance whose
effectiveness was greatly enhanced by improvements in
immunosuppressant drugs

9
Despite the consensus among economists that technology is a
driving force behind rising medical costs, the empirical evidence
in this area has been limited
beginning to change

Fortunately, that situation is

Some recent studies that focus on specific

medical conditions provide useful insights into both the costdecreasing and cost-increasing aspects of technology

For

example, analysts have documented a sizable saving in the cost of
treating cataracts, which thirty years ago required a long
operation and extended hospital stay but is now routinely done on
an outpatient basis

1

In contrast, a separate study exhibited

the potential for technology to raise costs

2

This study

examined the appreciable increase in Medicare outlays to treat
heart attacks between 1984 and 1991, which the authors attributed
entirely to the dramatic expansion of intensive cardiac
surgeries
The new technologies also carried other significant
benefits, contributing both to enormous improvements in the
post-operative vision of cataract patients and to longer life
expectancies and higher quality of life among heart attack
survivors

Parenthetically, this is the same measurement issue

that chronically bedevils economists who try to allocate changes

in dollar outlays on medical procedures between changes in price
and changes in real output

The problem arises for any good or

service for which changing technology is greatly affecting the
characteristics and quality of the output
Measurement issues aside, the fundamental point here is that
a structure that provides appropriate incentives for the
development and application of technology is key to a wellfunctioning health care system

In this case, an appropriate

incentive is one that encourages technologies whose benefits are
at least equal to their economic costs, while discouraging those
that do not meet that standard

It is still too soon to know how

the evolving incentive structure in private insurance markets
will affect the pace of medical technology

However, a recent

analysis provides some preliminary evidence that managed care may
be fostering a more efficient use of technology

3

If the results

continue to be borne out in the marketplace, we may be seeing the
beginning of a significant restraining effect on the growth of
health costs over the long run
Clearly, the jury is still out on many of the changes in
private health insurance markets, and some may turn out to be
unsuitable for Medicare

But some of these ideas, especially

those that improve efficiency or foster greater costconsciousness among users and providers of health care, are
worthy of study
3

In that regard, some Medicare beneficiaries,

Growth of Medical Expenditures," Working Paper 6140 (National
Bureau of Economic Research, August 1997)

11
attracted by the rich benefits packages offered by some HMOs and
frustrated by high Medigap premiums, have enrolled in these
plans, and the Balanced Budget Act of 1997 expanded the range of
options available to participants

Nonetheless, Medicare remains

largely a fee-for-service program

Unless its disparities with

the private sector are addressed, political support for Medicare
may well begin to wane, especially if escalating Medicare costs
force tax increases or reductions in other government programs
that serve important functions
Regardless of what changes are eventually put into place,
the nation should be prepared to revisit the issue of Medicare
reform--perhaps many times--as unanticipated technological
changes alter medical practice and private insurance markets
evolve

Other broad economic and social trends--for example,

unforeseen changes in labor market activity among the elderly-may also make adjustments in the structure of Medicare desirable
Perhaps the hardest issue with which you will have to
grapple is the very real possibility that the projected demands
by Medicare recipients exceed a realistic estimate of our
budgetary capabilities

Medical rationing is anathema to the

American psyche, though it often appears in subtle forms

We

know, for example, that we can never offer all new technologies
or medical procedures immediately to all patients who would
benefit

In practice, new technologies are allocated by

physicians who use their own criteria to choose the recipients
In this case, the system likely works largely because an

12
innovation that was not previously available does not seem to be
missed except by the most knowledgeable

That might not be

perceived as fair, but the thought of our political system
attempting to improve the process gives me great concern
Medical decisions have always raised difficult ethical
considerations

We expend vast resources to prolong life a few

weeks or a few months whereas some other democracies rely more on
hospice care and restrict the use of scarce equipment, especially
among older persons

We practice super high-tech medicine

although, as I suggested earlier, it is not clear how much it
raises average life expectancy or reduces morbidity
It is difficult to discern a consistent American standard in
these matters

When it comes to medical care, we seem to hold

life as an unequivocal value with pressures to fend off death by
any means, regardless of the costs in real resources

Yet we

tolerate more than 40,000 motor-vehicle-related fatalities a year
when modest restrictions on car use could lower the casualty
rate

The value of travel freedom and convenience clearly

outweighs life as an inviolate value

People demonstrate through

their behavior a willingness to risk life for other values
Indeed, risk is inherent in life and can be contained, but never
eliminated

Given the disparity between the way we deal with

risks in health and the way we deal with risks in other aspects
of our lives, one might expect a more calibrated real costbenefit analysis to emerge eventually as health care policy
matures

13
Before concluding, I'd like to offer a few points about the
experience of the Social Security Commission of 1982 that may be
relevant to your deliberations

First, I believe that the

Commission, which I chaired, succeeded, if that is the word,
because, from the start, it was integrated with the political
system

I kept President Reagan's chief of staff James Baker

informed of our deliberations on an ongoing basis

Robert Ball,

the former Social Security Commissioner and social insurance
professional, kept the Speaker informed

Many members of the

Congress also were members of the Commission

Senators Dole,

Heinz, and Moynihan and Congressmen Archer, Conable, and Pepper
The interplay between the deliberations of the Commission and
parallel policy discussions in the White House and the Congress
was continuous, ensuring political support for the final product
Had we not done that, the report would have ended up on the dustfilled shelves along with the many fruitless Commission reports
of the past
In the end, the large majority of the Commissioners, the
President, and much of the Congressional leadership signed onto
the principal recommendations in the Commission's final report
Tactically, we chose to do something unusual to help ensure that
our recommendations would be implemented

As with all tightly

crafted compromises, pulling one provision might have caused the
whole structure to unravel

Therefore, Robert Ball and I, the

designated presenters of the Commission's findings to the
Congress, agreed to defend the report in total

The internal

14
debates within the Commission were behind us, and we exhibited a
unified front to the Congress

In the end, the legislation that

passed differed little from the Commission's recommendations.
In conclusion, programs to support a rapidly expanding aged
population threaten budget balance in the early decades of the
next century

Preemptive action could avoid wrenching

disruptions to our federal medical programs and our economy
longer we wait, the more difficult the adjustments

The

Moreover, I

have no doubt that the budget discipline of recent years has been
instrumental in lowering long-term interest rates--a key factor
in our current economic vitality

Unless this discipline can be

sustained, our overall economic performance will be seriously
jeopardized

If this Commission can assist in expediting the

seemingly necessary adjustments to Medicare, the nation will owe
you an enormous debt of gratitude
