,WEEK 1 – L1 HEALTH CARE INSURANCE
The fair insurance premium is calculated based on the risk and probability of getting ill. Deciding on the real
premium for a health insurer is a hard decision as the premium should be low enough to attract people.
However, not too low as they should make up the costs of the healthcare costs from people that get ill.
Customer side → perform cost-benefit analysis (CBA) to choose whether you will insure or not → do I pay a
little upfront, or risk paying much more later in case something happens?
This scheme depicts a decision tree. Ultimately you want the highest amount of utils (= U) which can be
calculated via the equations in the picture.
- Income minus premium: (utils from wealth at time point 1 – premium) + (utils from wealth at time
point 2 – premium)
- Income minus health costs: (utils from wealth at time point 1) + (utils derived at point 2 with the
probability of getting ill - health care costs) → probability of DO getting ill
- Income: (utils from wealth on time point 1) + (utils at point 2 with the probability of NOT getting ill →
1-p)
The decision (or amount of utility) can also be altered by
1. Time preference: do I like to have more wealth now or in the future?
a. If you want more money now, compared to the future, you are less likely to take the
insurance
b. Interest rate (rente) says something about how we value money now vs in the future. If the
interest rate of the money is high, in the future, the money will be more worthwhile and they
will be more likely to spend the money in the future due to the additional rente gained
2. Loss aversion: how much disutility does it costs to lose a small amount versus a large amount?
a. Sometimes losing 10 euro’s feels worse than gaining 20 euro’s. In that case, more utils are
devoted to losing the 10 → negative impacts are weighted heavier compared to the
happiness gains
3. Risk aversion: play on safe or roll the dice?
a. Not risk neutral → you are risk averse if you are willing to pay small amount of money to
reduce losing a lot of money. You will choose to insure at a fair premium
Risk neutral → whenever losing an euro and gaining an euro is equal in utility. You will be indifference in paying
fair premium or paying for care. Example: 10% chance of getting ill: costs are $8.000,- → 0,1 * $8.000 + 0,9 *
$0 = $800. If it doesn’t matter to you whether you will insure or not, you are indifferent and thus risk neutral
Risk aversion can be calculated

, U = utility
P= change of risk
H = health costs
W = wealth
E(c) = expected costs
i = insurance premium
Expected utility E(U(H)) = p*U(W-H)+(1-p)*U(W)
→ calculates the utility of no-insurance (roll the dice)
Scenarios:
In the case of staying healthy → U(W)= 10,000wealth = 9.21U
In the case of getting ill → U(W-H)=10,000-8000= 2000wealth = 7,6U
In the case of being insured → U(W-i)=10,000-800= 9,200wealth = 9.13U
Expected utility if E(U(H)) = p*U(W-H)+(1-p)*U(W) → 10% of the cases 7.6 and 90% of the cases 9.21
no-insurance E (U(H))= 0.1*7.6 + 0.9*9.21 = 9.05
U in case of insurance U(w-i) vs U in case of no insurance E(U(H))
9.13U 9.05U
→ based on the utils, you would be better off by insuring
Maximum willingness to pay for insurance can be calculated by:
MaxWTP → U(W-inew) = E(U(H)) → indifference between insurance or not
U(W-inew) = 9.05
e9.05 = 8500 = W-inew
10.000 – 8500 = 1500 euro = inew
Law of large numbers: the more insurees, the more predictable your expected costs will be as a health insurer.
Include a lot of different insurees with different risks to pool the risk to an average that is profitable → risk
pooling
INSURANCE GIVES RISE TO WELFARE BUT ALSO MARKET FAILURES: MORAL HAZARD,
ADVERSE SELECTION, UNINSURABILITY
Because we are mostly risk averse we are likely to insure for our risks which makes that the health insurance
systems work and can provide us the health we need which increases welfare. However, still some market
failures exist. Therefore a lot of policies are needed (government intervention) to create a fair market,
consequently health insurance markets are heavily regulated
MORAL HAZARD → COST SHARING
When people have an insurance, you are going to take more risks because you will get the money back if
something happens. Freeriding on other insures premiums.
Prevent by → eigenrisico/deductible, cost sharing, nudging
ADVERSE SELECTION → MANDATE/SUBSITY
