Objectives of the course



The objective of the course is to acquire the abilities to model diverse market structures, detecting and evaluating the problems inherent in these structures, with a special focus on market power and strategic interdependence. First, we study non-cooperative Game Theory and show its usefulness in analyzing different economic phenomena characterized by strategic interdependence, characterizing markets with only a few competing firms. Then, we analyze different models of oligopolistic competition and the stability of collusive agreements, using game-theoretic concepts. Finally, we study the case of monopoly, focusing on different types of price discrimination.





Specific competences of the course



1.- To identify, model, and analyze economic phenomena related to market structures characterized by the existence of market power.

2.- Analyze multi-person election problems characterized by the existence of strategic interdependence using the game theory, propose solutions to these problems, and apply the game theory to oligopolistic markets.





Learning results



1.- Capacity to identify, to model and to analyze economic phenomena related to market structures characterized by the existence of market power.

2.- Capacity to analyze, by means of Game Theory, problems of multi-personal election characterized by the existence of strategic interdependence, to propose solutions to these problems and to apply the tools of Game Theory to oligopolistic markets.

3.- Capacity to use marginal analysis in the study of economic phenomena.





Cross-cutting skills of the course



1.- C3: To emit reasoned judgments and to make decisions on relevant questions with critical capacity. To analyze the information from different perspectives: verbal, analytical and graphical reasoning.

2.- C6: Capacity for written communication, specially in the elaboration of clear and coherent reports.

3.- C8: Capacity to work in groups, with responsibility and respect, initiative and leadership.



Contribution of the subject to the Sustainable Development Objectives.

1. Contribution to Goal 12

The subject contributes to a better understanding of the production processes and the inefficiencies that can be generated due to the concentration of market power. This analysis is useful for the subsequent design of sustainable production and consumption processes.

2. Contribution to Goal 13

Using the tools provided by game theory, we analyze the public good game structure of countries' contributions to climate change mitigation. This structure reveals the individual incentives for problem resolution and the gains from cooperation on this global problem.

3. Contribution to Goal 17

Using the tools provided by game theory, individual incentives for alliance formation and cooperation are analyzed from both a short-term and long-term perspective. The analysis of these individual incentives is key to understanding under what conditions the alliances will be stable and will allow a solid international cooperation.

Lectures, practical lessons, seminars and evaluable exercises.

Clarification: The key element are the lectures, in which we will develop the different topic of the course. In practical lessons, the professor will solve problem sets corresponding to the topic covered in lectures. During the seminar classes, the students will solve individually questions/problems related to the topic of the course.

The continuous evaluation is applied in the course. There will be one final exam (on dates specified by the Dean's office), in which the students will solve both theoretical and practical problems and which will account for 70% of the final grade. As part of the evaluation, multiple choice questionnaires and numerical exercises will be included. In addition, the students will be evaluated on basis of their work throughout the seminars all along the course. This second part will account for 30% of the final grade, whenever the mark of the final exam is at least 4 over 10. The evaluation of this work will be as follows: the students will solve problems and theoretical questions presented by the lecturer. Three of these tasks will be handed in to the lecturer for their evaluation. These tasks will be solved individually and/or in group.



Students who cannot participate in the continuous evaluation have the right to be solely evaluated on basis of the final exam on dates specified by the Dean's office. In such a case, their grade will be 100% based on the final exam. Students who will not take the final exam will be graded as 'No presentado'.





NOTE:

If health conditions prevent face-to-face teaching and/or presential evaluation, both activities will be adapted to online teaching and evaluation using the eGela teaching platform.
