Abstract

This paper is the analytical work describing evaluation methods of some types of information asymmetry. Duality of possible evaluations of information asymmetry is shown: in comparison to the similar object and the set goal. The types of informational situations where asymmetry occurs are described. The types of information asymmetry are described: on information, on information exchange, on information interaction, on information situation, on information flow. The ideas of the general state of object and the informational state of object are described. The difference between them is shown. The concept of awareness of the object or subject is given. The qualitative and quantitative evaluation methods of information asymmetry are given. It is shown that the asymmetry is possible not only on the state of object, but also on information flow coming to the objects. The limitations and possible negative consequences of qualitative estimates are shown. These analytical terms allow defining the informational characteristics of objects such as: "information superiority"; "adequacy of resource provision" or "lack of resource provision"; "possibility of achieving goal" or "failure of achieving goal"; "information asymmetry on resources" or "information asymmetry on the situation." The distinction between formal and actual information asymmetry is given. The idea of natural and artificial information asymmetry is noted. The idea of attributive and procedural information asymmetry is given. Recommendations to address the information asymmetry are given.
