asymmetrical information

Asymmetric information in economics refers to situations where one party in a transaction possesses more or better information than the other party. This imbalance can lead to market inefficiencies and unfair outcomes.12

Two key concepts arise from asymmetric information:

• Adverse Selection: This occurs when the party with more information can exploit it to their advantage, often leading to unfavorable outcomes for the less informed party. A classic example is the used car market, where sellers know more about a car's condition than buyers, potentially leading to the sale of "lemons". In insurance, individuals with higher risks might be more inclined to purchase policies, driving up premiums for everyone.342
• Moral Hazard: This arises when an agreement incentivizes misbehavior because one party is protected from the consequences of their actions. For instance, if an employer covers all traffic violations for an employee driving a company car, the employee might be more inclined to speed. In the 2007-2009 financial crisis, some bankers took excessive risks, assuming the government would bail them out.56
