Free competitive insurance market
Starting point: a free, unregulated competitive health insurance market.
The focus is on affordable individual health insurance, irrespective whether this is in the context of a voluntary or mandatory health insurance.
Equivalence principle
A free competitive insurance market will tend towards equivalence between the premium and the expected expenses of the insurer (claims plus loading fee) for each individual contract because competition minimizes predictable profits.
Therefore, insurers cannot organize ex-ante cross-subsidies among different risk groups.
Without any external intervention individual health insurance may be unaffordable for the (low-income) high risks in a competitive insurance market.
Risk rating and risk selection
- In a free competitive insurance market insurers have to break even, in expectation, on each contract either by
1. adjusting the premium to the consumer’s risk (risk-adjusted premiums),or
2. Adjusting the product (product differentiation),
3. or by adjusting the accepted risk to the premium (risk selection). - The premium differences can easily go up to a factor 1000.
Selection
Actions (not including risk-rated pricing by insurers) by insurers and consumers to exploit unpriced risk heterogeneity and break pooling arrangements (Newhouse, JEL, 1996)
Unpriced risk heterogeneity
a group of people who are in a pool and pay the same premium and can be high and low risks (community rating or risk rating) pooling of relatively high and low risks. Unpriced means that the premium is not adjusted to risk factors. Cross subsidies from low to high risks.
Adverse risk selection
low risks don’t want to pay the same premium as high risks and the low risks leave the pool and high risks stay.
2 ways for an insurer to achieve equivalence
premium differentiation or risk rating and selection
- Selection by insurers:
– Denial of coverage;
– Exclusion of preexisting medical conditions; when someone has had aids for example and then insurer says they will exclude the consumer for that medication
– Waiting periods;
– No renewal of contract.
- Selection by consumers:
– Within each premium risk group the high-risks are more inclined to buy insurance than the low-risks. adverse risk selection
No long term insurance
- In a free competitive market voluntary insurance can offer protection only during the contract period.
- In a free market the premium for an insured who develops AIDS, cancer or heart disease has to be raised in the next contract period. Or the insurer may not renew the contract.
There is no market for insurance against the risk of becoming a high risk in the future.
Without restrictions on free competition:
- a system of implicit cross-subsidies can not be sustained because unrestricted competition minimizes the predictable profit per contract.
- individual health insurance may be unaffordable for the (low-income) high risks.
- there is no market for insurance against the risk of becoming a high risk in the future.
Assumption: open enrollment
- We assume that there is an open enrollment requirement for a specified coverage.
- As long as insurers are free in setting their premiums, this assumption is non-restrictive.
- The ‘access’-problem that would occur in case of rejection can be reformulated as an ‘affordability’-problem to be solved by subsidies.
Two types of subsidies:
- explicit premium subsidies;
- implicit cross-subsidies.
Explicit premium subsidies
- Insurers are free to set their premiums;
- A subsidy system is organized by a sponsor (e.g. government) such that high-risk persons with unaffordable premiums receive a subsidy from a Fund that is filled by mandatory contributions.
- High risks pay their premium partly with the subsidy and partly out of pocket.
Several types of subsidies
- Risk-adjusted subsidies;
* Subsidy related to your risk factors - Premium-adjusted subsidies;
* The higher your premium, the higher the subsidy - Excess loss compensations to insurers.
* Retrospectively after a year the insurer receives certain compensation based on the actual expenses. For instance, for expenses above 10.000 the insurer receives full compensation. So for a person whose predicted expenses is 40.000, the premium is no longer 40.000 but 10.000. these excess loss compensations are an indirect subsidy to the high risks
Premium-adjusted subsidies are not optimal:
- they reduce the incentive for high-risk consumers to shop around for the lowest premium, and thereby reduce the insurers’ incentives for efficiency;
- They reduce the competitive advantage of the most efficient insurer.
- they induce over-insurance resulting in additional moral hazard;
- they create a misallocation of subsidies.
Risk-adjusted subsidies
Risk-adjusted premium subsidies can be based on the risk factors X that insurers use, such as age and health status.
If consumers received a risk-adjusted subsidy based on the same risk factors that insurers use, the differences in out-of-pocket-premiums ( premium minus subsidy) would be minimal and would primarily reflect differences in quality, taste, loading fee, or efficiency.
Risk-adjusted subsidies can make health insurance affordable at every new contract period. If the insurer increases a person’s premium as the person’s health status deteriorates over time, the future subsidy value will be adjusted to the change in the individual’s risk characteristics.
Risk-adjusted subsidies provide protection against the financial risk of becoming a future high-risk.
Additional subsidies
To the extent that some high-risk consumers are insufficiently subsidized, the risk-adjusted premium subsidies can be complemented by premium-based subsidies or by excess loss compensations to the insurers (= compensations by the sponsor for some or all expenses above a certain threshold for each individual).
tradeoff affordability - efficiency.
Premium subsidies (Modality A), 2 problems
- high transaction costs; fund has to know for everyone in the Netherlands what the risk factors are
- if you get the subsidy before you pay the premium, the insurer is not sure that they will receive that subsidy. People can spend it on something else. If the subsidy is paid after premium is paid, consumer can get a problem. If it is an extreme high premium, they cannot pay it themselves.
Risk Equalization
All countries that apply risk-adjusted subsidies give the subsidy to the insurer who deducts it from the premium. In this way the different risks that consumers represent for the insurer are equalized. We refer to this as Risk Equalization.
Two modalities of risk equalization are observed:
* The consumer pays the contribution C directly to the Subsidy Fund (Modality B);
* The consumer pays the contribution C to the Subsidy Fund via the insurer (Modality C).
Implicit cross-subsidies
1.Guaranteed renewability (GR);
2. Premium rate restrictions
Guaranteed renewability (GR);
after a year you get a new contract, even if you have developed a new disease. Ypu pay the same premium
– GR reduces competition; lock-in of high risks;
– Guaranteed standard premium after 40 years?
– Guaranteed standard coverage after 40 years?
Premium rate restrictions
– Community rating;
– A ban on certain rating factors;
– Rate-banding.
Premium rate restrictions
- Goal: to create implicit cross-subsidies from the low-risks to the high-risks.
- Effect: such pooling of people with different risks creates substantial predictable profits and losses for subgroups, and thereby
- may create an unlevel playing field for insurers, and
- create incentives for risk selection.
