The course provides a framework used to study strategic interactions between participants through their decision making. After completing this module, students will be able to (i) Explain some economic phenomena such as competitiveness, quality of labor force, salary level, impact of policies; (i) Modeling a decision problem, using game theory concepts and from the assumptions of the particular problem; and (iii) Use tools to solve them based on the principles learned. The main content is related to the goal of the game (solution concept), in which the Nash equilibrium plays an important role, depending on the form (static, dynamic, normal, extended, Bayesian) and information (complete, not enough). Thereby examining specific economic models such as oligopoly, job market signals, adverse selection, bargaining, auctions, and efficient wages.
