Practical Usability Problems in Business Economics

Abstract

The practical usability of research results is a special advisory function of business economics. Of great importance is in teaching the science-based business knowledge as well. The paper presents the main problems related to practical usability of business economics summarizing more than four decades of research results of the author on this aspect. The examined disciplinary problems are the questions of terminology, some mechanical takeovers from microeconomic topics, some financial decision-making recommendations based on so methodology which does not fit for actual practice, and finally scientifically unresolved issues originating within business economics. Among the latter are: some unclear relations of profitability indicators, product ranking by contribution margin ratios, problematic return requirement sharing for products by cost or price proportions, cost-related cross-sectional analysis and some methodological problems of project evaluation. Clarifying these questions is fundamental for professional education. This is also important for business economists and in particular small and medium-sized enterprises, since their opportunities for in-depth methodological research are very limited.
