The course aims to define and apply some mathematical methods and tools, in particular the theory of dynamical systems and the theory of games, to model the time evolution of social and economic systems. The systems considered are often adaptive systems, influenced by the presence of boundedly rational, heterogeneous and interacting agents. Some lessons will be devoted to a deeper analysis of some mathematical concepts already introduced in the framework of the course in General Mathematics in order to use them in more advanced applications. The formal methods studied in this course will give a general understanding of the setup of a mathematical model in economics and how the results obtained should be critically analyzed. This is obtained both through the analysis of some models given in the literature and by examples and exercises proposed in classrooom notes.

At the end of the course the students should be able to built and analyze mathematical models expressed by the formalism of dynamical systems and/or the theory of games, and a sufficient capability of using mathematical and logical tools to describe in a schematic way the behaviour of complex situations. These mathematical tools should enhance the approach towards the description and the management of time evolving complex economic systems, and favour the ability to interface with experts in mathematics and computer science in order to study the behaviour of economic systems by an interdisciplinary approach.

Dublin descriptors

Knowledge and understanding: At the end of the course the students should grasp the main parts of the program

Applying knowledge and understanding: At the end of the course the students should be able to apply the methods of game theory and the theory of dynamical systems to the solution of problems and exercises as well as to the translation of real life situations into mathematical terms and symbols, especially for social, economic and environmental systems.

Making judgements: At the end of the course the students should be able to see links and analogies between different systems and situations, as well as to manage complex systems and situations by using tools from mathematics, logic, graphical methods.

Communication: At the end of the course the students should be able to communicate what they learned by using a proper language and terminology, according to different kinds of audiences.

Lifelong learning skills: The students must be able to get new concepts related to the ones exposed in the classroom from books, lectures and internet-based devices autonomously, following personal paths for understanding

Modalità di
accertamento

By an oral exam the global knowledge of the topics in the course program is ascertained . In order to get a positive mark the student should prove a sufficient ability to represent by a dynamic model a real economic or social system and use mathematical methods  to deduce its time evolution. The same for game theory used to represent sitiations characterized by strategic intercacion. 

Disabilità e DSA

Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.

A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.
