ECONOMICS is the study of how individuals and societies choose to allocate scarce productive resources among competing alternative uses and subsequently to distribute the 'products' from these uses among the members of a society.
What is Economics?
4
Science about how best limited resources (optimal) can be utilized to satisfy (unlimited) need of health on the basis of individuals’ or society’s own choice.
What is Health Economics?
5
Health Economics, therefore, is the study of how scarce productive resources (health care and health) are allocated among alternative uses for the care of sickness and the promotion, maintenance and improvement of health.
What is Health Economics?
6
Why Health Economics? Health economics is concerned with the formal analysis
of costs, benefits, management and consequences of health and health care
Interested in understanding demand and supply of health and health care, as well as issues of equity and efficiency.
To understanding where funding does and should come from.

B. Determinants of health
Some examples:
• Age• Gender• Social status• Education• Family condition• Environment• Social policy
13
C. Demand for health care
Demand function for doctor’s visit= ƒ (price per visit, coinsurance rate, price of other goods, income, time price, health status, Age, education, …..)
14

Total price elastricity = % change in nr visits/ % change in total price = - 1,5
Visit fee elasticity = % change in nr visits/ % change in visit fee = - 1,0
16
Difference between Grossman’s and traditional approach to demand For health
1. It is not medical care per se that consumer wants, but rather health. Medical care demand is a derived demand for an input to produce health ( the demand for healthcare is derived from the demand of health)
2. The consumer does not merely purchase health passively from the market. Instead, the consumer produces it, spending time on health-improving efforts in addition to purchasing medical inputs.
3. Health lasts for more than one period. It does not depreciate instantly, and thus can be treated like the capital good that it is.
4. Health can be treated both as consumption and investment good.
Health care or health
17
Initial health status
Investment in health
Depreciation of health
Uncertainty
Health capital
18
Regression model for demand for health
Health = Constant + initial health status + investment in health + depreciation of health + uncertainty + error
Health = Constant + (father’s occupational status + etnicity)+ (education + physical excercise in leisure time) + age + indivdual’s occupational status + error
19
D. Supply of health care
All that influence the production of health services that makes health better.
Some examples: Private/public health care Labour market for health professionals Waiting period Establishment of health centres Law (equity in health care)
20
E. Market analysis
Production and consumption of health care in a non-regulated market.
21
F. Health Economic evaluation
Cost of illness studies Cost-effectiveness analysis Cost-benefit analysis Cost-utility analysis
Decision rules for effective resource allocation

G. Health care organisation and financing
Financing equation
TF + SI + UC + PI = P X Q= W X Z
• TF = Sum of taxation• SI = Social insurance contributions• UC = Out of pocket and user charges• PI = Insurance premium (voluntary or private)• P = Price of the service• Q = Quantity of the service• W = Quantity and mix of inputs• Z = Price of inputs
26
H. System level evaluation
For example:Health expenditure =ƒ (factors that influence demand, factors that influence supply)
Perspective Point of view from which the costs and effective (or benefit) are recorded and assessed.
The societal perspective is the broadest possible perspective,
because it includes all costs (no matter who incurs them) and all
consequences (both good and bad), regardless of who experiences
them.
If several perspectives are included in the analysis, the results
must be presented separately for each study perspective.
Equity concepts Market mechanism is considered fair/Nozick. Maximising greatest happiness for greatest numbers, but ignores
distributional aspects /Utilitarianism. Goods are distributed so that the position of the least well off in society
is maximized/ Rawls Equal shares of a distribution of a commodity which means equality in
health and health care/ Egalitarianism
32
Equity in health care
Principle of being fair to all, with reference to a defined and recognized set of values.
33
Horizontal equityThe principle that says that those who are in identical or similar circumstances should be treated equally
Vertical equity The principle that says that those who are in different circumstances should be treated differently Population s that are equally ill ought to be treated same; those that are sickest ought to get more.
Equity in health care
Elements of Efficiency
Do not waste resources
Produce each output at least cost
Produce the types and amounts of output that people
value most
These are the three main elements of efficiency

Elements of Efficiency

Technical Efficiency Cost-effective efficiency Allocative Efficiency
Technical efficiency requires that for any given amount of output, the amount of inputs used to produce it is minimized (e.g. hospital…??)
It requires that, in addition to technical efficiency being attained, inputs be combined so as to minimize the cost of any given output Resources be used to produce the types and amounts of outputs which best satisfy people
Allocative Efficiency
Example…!! If mothers of young children want counseling services for behavioral problems instead of frequent well-child check-ups, then allocative efficiency might be improved by changing the mix of primary care services even if the well child examinations were being provided cost effectively
If producers are supplying too much or too little of any good or service relative to consumers' wishes it leads to allocative inefficieny
Doing the right things Doing things right
Elements of Efficiency
Do not waste resources
Produce each output at least cost
Produce the types and amounts of output that people
value most
Technical Efficiency Cost-effective efficiency Allocative Efficiency
Efficiency means both 'doing things right' (technical efficiency and cost-effectiveness), and 'doing the right things' (allocative efficiency) Pareto Efficiency..?????
