Video Lectures on Epistemic Game Theory

In 2013, my lectures on Epistemic Game Theory at Maastricht University have been recorded. You can watch the videos of these lectures below. The idea is that in the near future, we will offer an online course on Epistemic Game Theory, where these videos will serve as a basis.

The course is based on my textbook Epistemic Game Theory: Reasoning and Choice, which has been published in 2012 by Cambridge University Press.


Below, you find an outline of this course, and the video recordings of the lectures.
