One concept in finance that is often overlooked is the phenomenon of adverse selection. This refers to the inclination of individuals who face higher risks to seek out more insurance coverage compared to those with lower risks. As a result, insurers may respond by either increasing premiums or refusing to provide coverage altogether. This can be particularly evident in natural disasters, such as earthquakes, where adverse selection can lead to a concentration of risk rather than its dispersion. To combat this, insurance is most effective when risk is distributed among a large pool of policyholders.
