Summary
Moral hazards and market bubbles are examples of market failures where individual actions can lead to negative outcomes for the economy.
- Moral Hazard — situations where one party increases their exposure to risk because they do not bear the full costs of the risk.
Example: In the insurance industry, buyers may take more risks knowing the insurer will cover the costs. - Market Bubbles — occur when rising demand drives prices beyond the expected level, often due to emotion and peer pressure.
Example: The housing market can experience bubbles when demand increases faster than supply, leading to unsustainable price rises.
