Information asymmetry occurs when one party in a transaction has more or better information than the other. This imbalance can lead to inefficient outcomes, as the less informed party may make decisions that are not in their best interest.

A common example of information asymmetry is in the used car market. A seller typically knows more about the condition of a car than a potential buyer. This can lead to adverse selection, where low-quality cars (lemons) are more likely to be sold because sellers can hide their defects.

Another instance is in the insurance industry. Individuals seeking insurance often have better knowledge of their own health or risk factors than the insurance company. This can result in higher premiums or the denial of coverage for certain individuals.

Information asymmetry can also be found in labor markets. Employers may not know the true productivity of a potential employee, while employees may be unaware of the full responsibilities or challenges of a job.

To mitigate the effects of information asymmetry, various mechanisms have developed. Warranties, third-party inspections, and reviews help reduce the information gap for consumers. Signaling, where the informed party takes actions to convey their information (e.g., education degrees for job applicants), and screening, where the less informed party designs processes to elicit information (e.g., interviews), are also important. Disclosure requirements and regulations aim to level the playing field by mandating the sharing of certain information.
