We view managerial economics as applied microeconomics. It helps the company manager to recognize the various economic factors at play and their impact on the company. Also, it helps in interlinking different economic concepts to build a better tool for managerial decision-making. Managerial economics applies economic tools and techniques to business and administrative decision-making to achieve business goals through efficient use of given business resources. It represents a method of directing business resources for effective management. Companies act by expanding their operations, becoming international, which makes their scope of work more and more risky, which puts the managers of such companies in front of special challenges for the successful management of these companies. Precisely reducing risk when making managerial decisions is one of the segments of managerial economics. On the basis of relevant facts about labor issues, the problem of this thesis can be defined, and it refers to the importance of managerial economics in international companies. The purpose of the work is to define the concept of managerial economics with further elaboration of related terms. The empirical part of the paper includes a qualitative analysis of management economics tools on the example of the international company Mepas Grupa. The aim of the work is to become familiar with the elements of managerial economics within the forementioned company and, using the theory of managerial economics, to identify factors that contribute to the improvement of business operations in the observed company. The paper will analyze the factors of managerial economics that relate to the company's operations. The method of building and maintaining a competitive advantage on the existing European markets will be presented through the presentation of the operations of a specific international company.
