Study Notes

Overview of Insurance

Insurance is an ancient concept that can even be observed in non-human animals through risk-sharing behaviors.
Policyholders enter into a contract with an insurance company or government entity to mitigate specific risks.
Premiums are paid regularly to ensure that the insurance company is prepared to manage potential risks.

Risk Pooling Theory

Central to insurance is the principle of risk pooling, where individual risks, when pooled together, diminish in overall risk.
The Law of Large Numbers enables insurance companies to predict outcomes by averaging risks across many policyholders.
In independent cases (e.g., life insurance), as the number of policies (n) increases, the standard deviation of expected outcomes approaches zero, making risks more predictable.

Importance of the Law of Large Numbers

Guarantees stable averages over numerous trials, leading to predictable outcomes in insurance.
Example: A casino expects stable earnings over many roulette spins, despite potential loss in single spins.
Another example is rolling a six-sided die, where the average result approaches 3.5 with increased rolls.

Challenges in Insurance

Moral Hazard: Insured individuals may engage in riskier behavior because they feel protected. For example, a homeowner may be careless with fire knowing they have insurance.
Fraud Risk: Insured value exceeding potential selling price can lead to malicious intent, such as intentionally damaging one's property for profit.

Selection Bias

Occurs when insurance companies cannot fully assess all risk factors, resulting in attracting higher-risk customers.
Health insurance often attracts those already sick, leading to financial strain on the company due to increased claims.
Solutions to mitigate selection bias include mandatory regulations, medical exams, and policy adjustments (e.g., preventing factoring of pre-existing conditions in Obamacare).

Practical Application Example: Crop Insurance

Subsistence farmers depend on their crop yields for sustenance, making crop insurance beneficial against unpredictable weather.
However, crop insurance is vulnerable to manipulation, such as farmers falsely reporting low yields to receive insurance payouts.
This creates a challenge in ensuring genuine claims and maintaining the integrity of insurance systems in marginal economies.
