Health Economics Flashcards
Health Economics
The study of the allocation of resources to and within the health economy
Curative care
The health service we receive when we are sick. It is more expensive than preventive care.
Arrow (1963): Is the health market different from other supply/ demand markets?
There is uncertainty on both the supply and demand side. Demand is in regular in nature, since consumers cannot know if they are sick before they go. Supply is uncertain since the physician´s cannot predict the outcome of treatments with certainty.
Theory of principal-agent (Is the health market different from other supply/ demand markets?)
There is asymmetry of information, since patients cannot know the quality of the health care they receive. Incentives towards reducing the problem can be better information providing and more transparency.
Akerlof (1970)-The Lemons Principle (Is the health market different from other supply/ demand markets?)
In the used car market, the potential buyers only know the average quality of used cars, so the prices are lower than the true value of the top-quality car. It makes the top-quality car owners hold back their car from sales. The good cars are therefore driven out of the market by the lemons. There is no market left. (Look in the notes for seeing how to apply it to the health insurance market)
Prevention
It has a present cost, but a future benefit
Moral Hazard
Ex ante: If you are insured, you are less risk averse because you know the consequences are limited.
Ex post: If you are insured, you are more likely to go to the hospital every time some little thing is wrong, which will have you overusing the system “Just because you can”.
Example on a moral hazard in health care: In the case that a doctor or a patient order an extra test “Just because it is free”.
Demand for health care/services
It is a derived demand, since what we really want is the demand for good health and not just a visit to the doctor. It can be influenced by the price of health services, income, type of insurance, educational level, age, lifestyle, quality of care, health condition, time costs to reach the medical care and the prices of alternative treatments.
Law of demand
Inverse relationship between price and quantity.
The relationship between medical care and health improvements
It is not exact, since there is uncertainty connected with the type of care needed to get better.
The effect of income on demand
An increase in income increases the demand, so it shifts the demand curve outwards.
The effect of health insurance on demand
The demand is dependent on the type of insurance you have. You can have co-insurance, indemnity insurance or deductibles insurance.
Co-insurance
Consumer pays a fixed percent of the cost (say 20%) and the insurance company picks up the rest.
Indemnity Insurance
Pays a fixed amount for each type of services (say $150 if you go to the emergency room).
Deductibles
Consumer must pay out of pocket for all health care, until reaches a threshold (such as $1000), then is fully reimbursed for expenses above the threshold.
The effect of education on demand
The effect of education on demand be either positive or negative. Educated people tend to be more proactive to keep themselves healthy, so they need less medical care. They want to stay healthy so they can work more and earn more. Besides that, they might also know more about when they need to get medical care, so they go more often. There is although empirically evidence showing that educated people tend to demand more medical care.
The effect of demography on demand
Very young people and elderly demand more medical care. They are typically also the ones with a lower health status. Also, females demand more health services, during their child bearing.
The effect of substitutes and complements on demand
Substitutes and complements can have the prices both decrease or increase. Substitutes can be herbal or non-western medicine. If prices of that goes up, then the demand for health care will go up as well. Complements can be drugs. If a person cannot afford to pay for the drugs, then they might not bother going to the doctor. So, if the price of a complement rises, the demand for health care will decrease.
The effect of travel time costs on demand
The demand of health care depends on how long it takes to get to the doctor and if there is any waiting time there. If there is a long way, then people will only go in urgent cases and the demand will therefore decrease. It is an important factor in developing countries.
Co-payments
Additional payments for the health care services paid every time you go. Co-payments can be good if they were income decided, since they would prevent people from misusing the system and thereby make the system more efficient. They would constitute to a more sustainable health care system. Arguments against co-payments are that poor people would not go, or they would go but so late that they would need an even bigger treatment.
Behavioral hazards
We have an example that behavioral hazard suggest that we need an even larger co-payments for the overused drugs. (Elaborate more). Behavioral hazard is the opposite of moral hazard.
Asymmetric information
When one party in a trade knows more about the other, which is of relevance to the trade. Ex. when a doctor knows more than the patient, but simply choose not to tell the patient everything.
The agent/principal theory
It is the conflict between clinical freedom and social efficiency. The objective of the principal is to minimize the costs and getting the agent to apply with the goals of the organization. The double agency relation is when doctors are the agent of the financer, and the patient (Or the doctor) has a dominant position in the market. There are 4 different levels of the principal agent: Taxpayers (1), government (2), health manager (3) and doctors (4).
The incentive mechanism
The physicians have intrinsic motivation since they are aware of the relevance of their performance and have a high intellectual level. Most of them are unsatisfied since they work under an incentive mechanism, where they are either monetary rewarded or punished.
