    3 hour lecture in 8 min..wonderful!!! Especially stating you can cross off the choices/nodes that will not be reached.

    The elimination of the payoffs, comparing and cancelling the last player's least payoffs, and continuing until reaching the first player's payoffs were eye opening! Thank you so much. This was so helpful in creating an easy way to cancel out the least beneficial payoffs while easily showing the best payoffs/Nash EQ. My prof didn't teach us this and this video has been a game changer for my upcoming final exam.
    THANK YOU!!!

    Great explanation. Game theory was one of my favorite subjects as an econ undergrad at UCLA. I wish more people had this basic understanding and saw how it drives decision-making in business, international conflicts and other areas.

    Ashley. You got an extraordinary talent to explain topics from a student perspective. Last year you explained me the classical Game Theory, in a new module this semester we tackled backwards induction and I saw you again. And again great work! Thanks a lot! You are great!
    Best Regards from Germany.

    Hi Ashley! Thank you so much for uploading these for all of us! Im in a managerial economics course for my MBA and I have sent fellow students in the class to watch your videos (the best ones on TH-cam imo). I was wondering if you happened to have or could upload a simpler one for them with two players. Some are having difficulty understanding the two player game trees and this may be a bit overwhelming even though you've color coded and explain it perfectly!! Again, tysm!!!!

  • @josephsmyth832
    @josephsmyth832 ปีที่แล้ว

    So essentially game theory has nothing to do with right conduct since it’s used as progressive discipline at work and therefore it lacks any truth and justification as it’s not based on material facts and direct evidence, correct? This also is used in law.

    • @AshleyHodgson
      @AshleyHodgson  ปีที่แล้ว +1

      Game theory is a theoretical framework, but tons of evidence points to the fact that it works well to explain many biological and economic phenomena. That is not to say that it "always" applies. But in cases where empirical evidence points to game theory, it performs well at predicting a variety of things.
