  • Game Theory for Ph.D. Students


  • Basic Informations

  • Topic 1: models of strategic interaction and the role of information

    Introduction to the basic language to deal with situations of strategic interaction.

    It is probably the most difficult part of the course, however it is important to get able to manage the fundamental basic tools of game theory. Hence, we will use much time to be sure everyone is able to use such language.

    • Lecture 1

      1. Introduction to game theory
      2. Formal models of games:

  • Topic 2: Games Solution using Dominance and Bayesian Rationality, and the Role of (In)Complete Information

    Introduction to the most basic concepts of games' solution: dominance (strict and weak, simple and iterated) and Bayesian rationality (simple and iterated), with a specific emphasis on the role of Complete or Incomplete Information
