Asymmetric information refers to a situation in which one of the parties involved in a market transaction has more information than the other, which reduces efficiency in resource allocation. The basic reasons are the high cost of information acquisition, blocked information transmission channels, and lack of enough information disclosure. Problems such as adverse selection and moral hazard created by asymmetric information damage the efficiency of the market. Asymmetric information has played a very important role in lending, hotel, and catering. As for the industry of lending, the existence of asymmetric information between borrowers and lenders would make it easy for high-risk borrowers to obtain loans and, further, increase the risk of default. Asymmetric information within the hotel industry makes it hard for consumers to judge the hotels service quality and price rationality. Asymmetric information affects investment decisions and enterprise efficiency in the catering industry, distorting valuation and causing investment loss. Addressing asymmetric information in various industries is crucial for fostering market transparency and efficiency. To achieve this, researchers must employ both signaling and screening models to mitigate the adverse effects of information asymmetry. This paper examines historical literature on asymmetric information across diverse industries and delineates strategies to enhance information transparency and promote more informed decision-making.
