Information asymmetry, also known as "information failure", is a phenomenon that occurs in non-perfectly competitive markets where some business entities have more valid information than others. This difference in information leads to a competitive advantage for those businesses with more complete and accurate information. As a result, their business performance is better than that of their competitors.

The research conducted by economists Akerlof, Spencer, and Stigitz has demonstrated the impact of information asymmetry on market participants. Their research has consistently shown that information asymmetry leads to differences in the information that market participants possess, and that the more complete and accurate the information, the greater the competitive advantage for the business entity. This advantage translates to greater market power and success.

Business entities with large and complete effective information will use the theory of information asymmetry to seek maximum benefits for themselves. Conversely, business entities with insufficient effective information will suffer corresponding losses. This leads to a situation where some businesses take more while others eat less.

Existing research has identified two problems brought about by information asymmetry: adverse selection and moral hazard. Adverse selection refers to the problem of information superiority, where the disadvantaged party cannot control the overall situation and make correct trading decisions. This leads to market distortions, supply and demand imbalances, product quality imbalances, and market failures. Moral hazard, on the other hand, occurs when economic man seeks their maximum economic interests by harming the economic interests of others.

In conclusion, information asymmetry has a significant impact on market participants and their business performance. The more complete and accurate the information possessed by a business entity, the greater their competitive advantage and market success. Adverse selection and moral hazard are two problems that arise from information asymmetry and can lead to market failures
