Definitions
Market = where demand and supply adjust through
price. can be seen as a tool or mechanism, for
allocating resources in a society.
Market failure = all the ways in which a specific market
may not meet the conditions for social optimality.
E.g. if there are barriers to entry, or a lack of information, then that market
will fail to produce the best possible outcome.
In bureaucracies “government failure” = the ways in
which a bureaucratic approach may fail to optimize social
welfare.
Market mechanism
Markets produce goods
efficiently by balancing
demand and supply
through the price
mechanism
Market distribute goods
according to the ability and
willingness of consumers to
pay for them –
demand/supply.
Conditions for perfect market
1. Perfect information
- Symmetric
2. ‘Rational’ behavior
- Incorporating both individual and societal costs/benefits
3. Market exists
- for all products desired by all people
4. Many buyers and sellers, homogenous products
- so each is price taker
5. Equity or politics not considered
Market failures
1.Imperfect information
2.“Irrational” behavior
3.Externalities
4.Public goods
5.Incomplete competition
Reason for government intervention:
Regulation, legislation, provision, …
Also: social equity
Information asymmetric
= One party to a transaction has better information that
the other.
e.g. car salesman, market for insurance or credit.
Leads to less than ideal provision:
-People avoid products
-People pay less/more than what it might be worth
Unless:
-use of warranty, reputation
-Performance related payments
-Norms and standards
Information asymmetry - Health
Uncertainty about products:
Knowledge patient/doctor
Difficult to distinguish products (heterogeneous)
Supplier-induced demand
Over/under-production
Low quality, high price
Role of government:
Accreditation
Quality Assurance
Health education
“Irrational” behaviour
= People might not always do what is best for themselves
(still “rational” choice based on personal utility)
Leads to:
- Over-consumption of “bad” goods (cigarettes)
- Under consumption of “good” goods (education)
Need to change incentives…
Externalities
Side-effect of consumption or production of goods and services,
that are not considered when consuming/producing.
Positive externalities:
Individual benefit < social benefit
Individual cost > social cost
Under-production / consumption
Negative externalities:
Individual benefit > social benefit
Individual cost < social cost
Over-production / consumption
e.g. listening to
the radio from a
person in the
next room, well-
kept front
garden, public
artwork,
volunteer,
vaccine
e.g. pollution,
over-fishing,
smoking
Externalities - Health
Positive externalities
E.g. prevention contagious disease, immunization, treatment
STDs, caring
benefit of consumption/production is lower for individual for
society as a whole
price paid will be below price it is worth
supply will be below what is ideal for society
Role government:
Subsidize consumption/production
Provision create market
Funding
Public Goods
= non rival and non-exclusive good
E.g. radio broadcast, fresh air…
Impossible to set a price:
Non payers cannot be excluded
Extra consumer doesn’t lead to extra costs
No body willing to pay (free riding)
Nobody willing to supply
No additional
costs to extra
consumer
No one can be
excluded from
consumption
Public goods - Health
Healthy society:
Everyone benefits
Incentive to “free ride”: leave the healthy life-style and preventive
measures to others.
e.g. incentive not to be vaccinated if everyone else is?
Who would invest in Research and Development for medicines in a completely
liberalized private market?
Role of government:
-Subsidize consumption/production
-Provision
-Funding
-Regulation (e.g. patient law)
Incomplete competition
= One or few providers of goods (monopoly: single seller), or one
or few buyers of a goods (monopsony: single buyer), who thus
have power in the market to influence prices.
e.g. OPEC: artificially high prices because of power of suppliers (as
long as no alternatives)
artificial shortage of oil
Incomplete competition - Health
Health care facilities often monopolies:
High start-up cost (investment in building and equipment, risks)
High barriers to enter market as supplier (specialized, long training,
licensing)
Limited choice for consumer:
Price set higher than costs, no incentive to be efficient or to provide quality
services
Role of government:
Provision
Quality control
Price regulation
Legislation
Equity
Equity = being fair or just.
Perfect market
technical (how) and allocative (what) efficiency,
regardless of who gets
so inequality is not a market failure
BUT
Still reason for government intervention
Trade-off between equity and efficiency?
Social welfare as positive externalities?
Equity - Health
Health = Human right (Constitution of Kenya 2010)
Ethical duty of health workers to treat according to NEED, not
ability to pay.
In private market:
Less supply at higher price than ideal for society
Role government:
Guarantee human right for good health
Provision
Subsidizing
Funding
Recap…
Perfect market
Market failures
Government intervention
Legislation, regulation, subsidizing/taxation, funding, provision,
social protection, …
Government failures
1.Imperfect information
2.“irrational” behavior
3.Externalities
4.Public goods
5.Incomplete competition
6.Equity
D=S, price adjusts, efficiency
Government interventions
Enabling
Changing environments
in which private agents
make decisions (making
markets work)
Public Provision
Government provides
health care services itself
Examples:
Subsidies, user fee,
exemptions, quality
standards, regulation
Examples:
MoPHS, MoMS,
vaccination programme,
research KEMRI
Market and government - health
Elements of both market & government in health care:
Public funding of primary health combined with user fees for other,
less essential services
Private health insurance combined with social insurance
Government subsidies/funding of education for health care workers
but re-payment of student loans by employed workers
Health education and information to assist consumer choices
Public sector contracting to private sector including PPPs.
