Adverse selection in insurance refers to a situation where either the buyer or the seller has information about features that the other party doesn’t have.
Adverse selection is a popular scenario in the insurance sector where people in high-risk lifestyles or those employed in dangerous jobs sign up for life insurance coverage as a way of protecting themselves from approaching risk.
On the other hand, insurance companies reduce their exposure to such high-risk claims by limiting coverage to such categories of people. Moreover, insurance companies can choose to raise the premium with the level of risk exposure to compensate the company for the risk of covering high-risk policyholders.

How Does Adverse Selection Work?
Adverse selection happens when one party in a transaction possesses more accurate information than the other party. The other party with less accurate information is at a disadvantage because the party with more information stands to earn more from that transaction.
The imbalance of information causes inefficiency in the price charged on specific goods or services. Such situations may occur in the insurance sector, capital market as well as in ordinary marketplaces.
Concerning the insurance sector, insurers find that high-risk people are more willing to take out and pay more significant premiums for policies. If the company charges a nominal price, but only high-risk consumers buy, the company takes a financial loss by paying out more benefits.
But, by increasing premiums for high-risk policyholders, the company has more money to pay those benefits. For instance, a life insurance company charges higher premiums for race car drivers. A car insurance company charges more for consumers who live in high-crime areas. Similarly, a health insurance company charges higher premiums from customers than some.
How Does Adverse Selection Work in Health Insurance?
In health insurance, adverse selection refers to the situation in which higher-risk or ill individuals, who have greater coverage requirements, purchase health insurance, while healthy people hesitate or don’t buy. This leads to an atypical distribution of healthy and unhealthy people signing up for health insurance.
For instance, assume a company offering a health insurance plan with a premium of $500 per month and coverage for everyday health issues. A person with health problems and diabetes may look at the $500 plan and think that it is a bargain since he knows that he would spend more on healthcare throughout the year. Consequently, he would sign up for the plan along with others in similar situations.
On the other hand, a 30-year-old healthy person may view the $500 plan as too costly. He and other healthy individuals may decide to look for lower coverage policies or will not buy insurance at all.
The two scenarios result in a problem where the group of insured people contains a disproportionately large number of sick people who will often use their health care coverage.

What is the Effect of Adverse Selection?
Adverse selection can negatively influence health insurance companies financially, thus leading to fewer insurers to choose from in the market or higher rates for those who purchase a policy.
As healthy individuals drop out of the health insurance marketplace, insured people’s pool contains more high-risk policies. As a result, the company would be forced to pay out a more significant portion of claims as compared to the number of policies in action because a disproportionately high number of insured people are utilizing more health care.
Also, the lack of healthy people can reduce the total amount of premiums that the insurance company receives. Consequently, this forces the insurance company to raise health insurance rates to make up the difference. However, this can also influence more healthy people to give up their policies due to increasing health insurance costs.
What is Anti Selection?
Anti selection is a term often used in conjunction with adverse selection. It is defined as an increase in the chance for a person to take out an insurance contract because they think their health risk is higher than what the insurance company has allowed for in the premium amount.
Anti-selection takes place because of anti-selection behaviors by people with higher health risks. Since sick people are more inclined to enroll and use more benefits, the insurance company must increase rates to fund the excess claims. This, in turn, pushes healthier applicants away from enrollment.
The Solution to Adverse Selection
One of the ways for insurance companies to avoid adverse selection is by grouping high-risk individuals and charging them higher premiums. For instance, insurance companies charge different premium rates to clients depending on their health condition, weight, age, medical history, hobbies, occupation, and lifestyle risks such as obesity, smoking, and diabetes.
The aforementioned factors influence a person’s health and life prospect and can determine the company’s potential to pay a claim. During underwriting, the company should decide whether to give a potential client an insurance policy and calculate the premium to charge a certain client.
Adverse selection occurs in health insurance when there is an asymmetry of high-risk, sick policyholders, and healthy policyholders. The imbalance can happen due to ill individuals who need more insurance using more coverage and purchasing more policies than the healthy individuals who require less coverage and may not buy a policy at all.
Adverse selection leads to financial risks for insurance companies and higher health insurance premiums for consumers. Insurance companies have three options for protection against adverse selection, including identifying risk factors, having a system for varying information, and placing caps on coverage.
