Asymmetric Information
Asymmetric Information
Asymmetric information occurs when one party involved in a transaction has access to more or superior information than the other party. This imbalance can lead to suboptimal decisions and market failure. This issue is commonly seen in situations where the seller has more information than the buyer, although it can occur the other way around.
Moral Hazard Problem in Healthcare Insurance
In the realm of healthcare insurance, moral hazard arises when individuals with insurance coverage alter their behaviour, leading to increased utilization of healthcare services. This is due to the psychological security provided by insurance, insulating individuals from the full cost of healthcare.
Design Note: A visual depiction of an individual with healthcare insurance indulging in risky behaviour, like overeating or smoking, knowing well that their insurance will cover the potential health issues, could effectively portray the concept of moral hazard.
Suppose an individual possesses comprehensive healthcare insurance. With this financial safety net, the perceived cost of additional healthcare services—additional blood tests, MRIs, medication, or further doctor visits—can appear insignificant. This perception, detached from the real cost of services, catalyses an overuse of healthcare facilities and services.
Moreover, insured individuals may neglect their health, knowing that they have insurance to fall back on. This change in behaviour and attitude towards personal health can lead to increased long-term healthcare costs, putting additional pressure on the healthcare system.
The impact of moral hazard isn't limited to individual behaviour; it also exerts considerable strain on the healthcare insurance market. The overuse of healthcare services spikes demand, which subsequently increases healthcare costs. As these costs inflate, insurance companies are forced to hike up premiums to cover their liabilities, perpetuating a vicious cycle of cost escalation. Eventually, the insurance premiums may become unaffordable for many, leading them to exit the market.
Adverse Selection in Healthcare Insurance
Adverse selection is a pervasive issue in insurance markets, including healthcare insurance. It arises when individuals with a higher risk profile—those more likely to make an insurance claim—are more inclined to buy insurance. This disproportionate representation of riskier individuals in the insurance pool can lead to market destabilisation.
For instance, consider a pool of insured individuals comprising smokers and non-smokers. The smokers, who are at a higher risk of contracting illnesses such as cancer, would logically require higher coverage. Let's assume there are 100 smokers, each contributing $1,000 to a mutual fund for potential cancer treatment, totaling $100,000. Non-smokers, with a lower risk, only need to contribute $500 each since they are less likely to contract cancer, creating a fund of $50,000 for the same number of individuals.
However, if smokers misrepresent themselves as non-smokers to avail of the lower premiums, it disrupts the balance of the insurance pool. The cost of insuring the supposed non-smokers inflates because of the increased risk. Consequently, real non-smokers may deem the insurance poor value for money, causing them to leave the insurance market altogether. This withdrawal amplifies the adverse selection problem, leading to a market dominated by high-risk individuals and potentially higher insurance premiums.
