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.
