Research Progress of Information Asymmetry in Recent Ten Years

Abstract

The assumption of information is the basis of all basic financial ideas (net present value, portfolio theory, capital structure and option pricing). The assumption of information is often inseparable from information asymmetry. Information asymmetry is a rich and diverse content, which can be connected with many fields. Asymmetric information may hurt sellers with more information and superior products, such as agent problems. Research at home and abroad shows that information asymmetry will cause many problems, but there is a lack of specific research evidence. In recent ten years, information asymmetry has had a great impact on both business society and daily life. This article reviews the relevant literature and summarizes the phenomenon of information asymmetry at home and abroad in the recent ten years, so as to increase the understanding of information asymmetry and lay a foundation for the trend prediction of information asymmetry in different environments in the future.
