Mode of delivery The teaching method is face-to-face, with lectures both theoretical and practical. Accordingly, students are invited to interact with the teacher and with colleagues in the resolution of the proposed exercises. The degree of commitment to these exercises will be taken into consideration in the final evaluation.

Learning outcomes This curricular unit (CU) is intended to:
- Strengthen the knowledge from the microeconomics courses;
- Acquaint the students with the tools of game theory, illustrating the theoretical concepts with microeconomic applications (case studies), always on the complete information usage;
- Formulate theoretical frameworks that capture the fundamental elements of the strategic interaction among microeconomic agents;
- Understanding how the surplus is distributed from the negotiation processes among firms.
The student acquires skills to analyze interactions, cooperative or competitive, where economic agents know that the result of their actions is dependent on its own, but also it is dependent of the actions taken by other agents and the timing of the decision. At the end of the CU the student should be able to explain how the interaction between firms causes stable equilibriums.

Teaching Methodologies and Assessment Criteria The teaching method is face-to-face, with lectures both theoretical and practical. Accordingly, students are invited to interact with the teacher and with colleagues in the resolution of the exercises. Planned applications, simulations and exercises are realized. Based on the exercises provided by the teacher, the students are invited to solve worksheets at home. Learning activities include planned office hours, schedule meetings and e-learning activities, and email. The continuous assessment is a weighted average of three components: Two written tests, at the middle and end of the semester, equally weighted. The non-admission exam involves a less than 6 val classification on continuous assessment, or plagiarism practices.
Language Portuguese. Tutorial support is available in English.
