The economic arguments as to why governments should or
should not intervene in the health care market all centre on the concept of
efficiency. What we mean by this is the Pareto efficient standard- the
inability to make someone better off without making another person worse off.
The First General Welfare Theorem states that under perfect competition and information,
the allocation of resources will align such that the economy reaches a Pareto
efficient equilibrium. However, moving away from this highly theoretical
perfect world, what are known as ‘market failures’ cause many aspects of our
economy to be fail reach this lofty
standard, and some are even highly inefficient. However, just because there is
a lack of efficiency, does not give a government cause to intervene- it should
act if by doing so it can increase overall efficiency in the market place,
taking into account all explicit and implicit costs. As almost all government
activity is financed through taxation, it is also hugely important to account
for any distortionary effect taxes have (for example, income tax tends to
reduce the amount of labour supplied at lower income levels).
Regarding the market for healthcare, it is useful to first
consider what it would look like were there no government involved. Thus, all
healthcare would be financed via private insurance companies, and hospitals
would be run as private companies. Such a system would be suffer from many
market failures, and would not be Pareto efficient. The reasons why are laid
out below.
Bounded Rationality:
Pareto efficiency assumes that there is perfect information among all actors,
and that people make rational choices. However, as healthcare is in of itself a
very technically complex subject matter, there is a limit to what one can
learn, without actually becoming a doctor themselves. Thus, people will not be
able to make fully informed decisions, and will need to rely on the advice of
doctors.
Monopoly of Doctors: Unlike
other goods, such as food or housing, people do not generally have the ability
to ‘shop around’ for the best deal on prices, particularly in times of
emergency. Most doctors meanwhile belong to a medical practitioners association,
and often consult on prices. In addition, they have little motive to compete on
prices, being more motivated by prestige than money.
Adverse Selection: People
are much more aware of their physical health than insurance companies are. With
medical insurance being quite expensive, healthy people, knowing they are
unlikely to need it, will opt out, while more unhealthy people, thinking the
opposite, will buy health insurance. This will cause premiums to rise, driving
more people out of the market, except the unhealthy, who will still save money
by being insured. This will eventually result in only the unhealthiest being
left in the market, with insurance companies being unable to function.
Moral Hazard: Once
one has paid their healthcare premium for the year, the cost of going to the
doctor or using the healthcare service effectively drops to zero. Thus, people
will go to the doctor more frequently than they need to, leading to
over-consumption of healthcare. In addition, many healthcare factors, such as
pregnancy, can be exogenous in nature. One could purchase health insurance, and
then choose to have a child, forcing the insurance company to pay for your
healthcare costs.
Incomplete Contracts:
Actuarial insurance rests upon the principle that the probability of any
risk occurring is less than 1. If it is exactly 1, then it is not a risk, but a
certainty, and will thus be uninsurable. This is exactly the case with many
inherited diseases, making it impossible to get insurance. The problem becomes
even more severe when one considers advancements in medical screening, and
would lead to a vastly unequal, eugenics-lite society.
As a result of the above failures, the market for healthcare
would be plagued with inefficiencies. Whether or not the government should
intervene however, and the scale that intervention should take, is widely
debated. This has given rise to several competing theories.
Neoliberal Approach
This approach argues that healthcare is so prohibitively expensive
precisely due to excessive amounts of government regulation. For example, by
restricting the right over who can and cannot call themselves a doctor, the
government ensures that doctors salaries will be very high, as will the cost of
healthcare. In addition, despite all the attention it receives, healthcare is
just one factor which effects one’s health and well-being, and public
production does little to reduce the gap between rich and poor in terms of life
expectancy. By allowing for private production, you ensure high levels of
standard. Low income individuals meanwhile, can receive transfers in order to
allow them to purchase insurance. This was the system used in the United States
prior to the introduction of Obamacare.
Pros: No waiting
lists, high levels of technological advancement, excellent standard of
healthcare
Cons: little
empirical evidence to support idea, large number of uninsured, high costs
Public Provision
This approach starts by acknowledging that healthcare is
itself not a normal good which should be subject to the whims of the free
market. It suffers from too many market failures, and so public provision is
the most efficient way forward. This is the system used in the UK, the NHS.
Almost all healthcare is provided free of charge to the public. This allows for
the correction of almost all the aforementioned market failures, except moral
hazard- people tend to over-consume healthcare, which leads to waiting lists.
As there is no discrimination based on pre-existing medical conditions, people
get the healthcare they need. It also tends to be very cost efficient,
particularly compared to its neoliberal rival. In 2007 in the UK for example,
average spending on health per person was $3,000, compared to $7,000 in the US.
However, because it is free, rationing is essential, and government intervention
tends to focus more on value for money than medical innovation. In addition,
there is strong empirical evidence to suggest that the rich and middle class benefit
more from this system than the poor.
Pros: Cost
efficient, all are insured, no market failures,
Cons: Waiting
lists, low innovation, wealthy benefit more.
Hybrid approach
Most governments do not use either the US or the UK as their
model, instead they factor somewhere in between. Healthcare is provided by
insurance companies, and is mandatory, although people cannot be discriminated
against. Premiums are subsidised by the government. This approach tends to have
slightly higher costs than the UK model, but much lower waiting lists.
