SECS-S/06 - 9 CFU - 1° Semester

- .Knowledge and understanding. The student will receive the basic tools allowing to deal with the modern formal approaches to economics and business management. The focus will be on the basic principles of mathematics applied to economics rather than on a sterile technicality. The course will give also an idea of the possible applications for the tools introduced. More generally, the course will try to educate students to a rigorous approach to the analysis of economic and management business phenomena. The rigor of the mathematical treatment will allow the student to acquire a mindset that will be beneficial for all the other subjects of the university course and then, more generally, for all the professional issues that have to be handled.
- Applying knowledge and understanding The student will be given the opportunity to analyze rigorously a mathematical problem and to use the basic concepts in order to draw appropriate conclusions. The student will be able to solve simple but not trivial mathematical problems. The student will be able to conduct a mathematical reasoning through the introduction of rigorous definitions and the demonstration of some theorems particularly significant. The student will also be able to apply the knowledge learned in the course to the formalization of some basic economic and management business issues such as profit maximization and utility maximization.
- Making judgments Students will be educated to elaborate by themselves the most appropriate approach to the proposed problems avoiding sterile applications of repetitive patterns. The student will be educated to judge the considered mathematical formalization by different points of view such as the elegance of the model, the power of the mathematical tools, the computational burden and so on.
- Communication skills Students will be able to learn the technical terms and they will learn how properly express the mathematical formalization of the problem and the results obtained with it. Students will be able to give a formal presentation of economic phenomena and management business . The student will critically discuss quantitative models related to economic and management business phenomena.
- Learning skills Taking into account the ever increasing use of mathematical formalization in economics and management business, the course will enable to access the more qualified literature in these areas, giving an essential basis for future learning in both educational and professional level.
