ENAbstract. Economic analysis of law is currently a dominant paradigm in corporate law doctrine. However, when researching in the field of law and economics, a scholar immediately faces the issue of different meanings of the same concept used by law and economics. This raises a question, can these different meanings be reconciled or translated from one field to another without losing its initial meaning? Thus, the article discusses theoretical insights related to incompatibility between law and other sciences as well as illustrates discrepancies in different realms by corporate law and economics examples. The article also discusses several implications of such discrepancies between economic and legal realms. Keywords: interdisciplinary, corporate law and economics, incompatible realms.
