Thanks so much. This was very helpful

You're very welcome!n Thanks for the comment!

[@jonathanchen9587]

Such a life saver. You helped me understand this right before my quiz on game theory

[@econhelp44]

Oh wow! Good luck, I'm so glad I don't have to do quizzes anymore haha. Hope you did well :)

Thank you so much you made this so easy to understand. its beter than how i was taught. this is 25% of my exam

Yay! Good luck with your exam!!!! Thanks for the comment 😀

Btw, do you have any notes or recommendations on macro economics books that are easy to understand because I will be taking it for the next semester ? thank you very much. You have saved my future. hahaha

[@econhelp44]

Hi Shamira, Macro is hard because I think the curriculum differs depending on where you are, so for example, Australian curriculum is a little different to the US. Given this, I strongly suggest that you concentrate on the text given by your lecturers (a good piece of advice in any case). Apart from this, I think Karlan and Morduch are pretty good. Hope that helps! :) Good Luck!!

[@shamirabintihamzah3902]

@@econhelp44 thanks for replying and I think I should opt for your advice by concentrating on the notes given by my lecturers cause economics is a minor subject for my course. That's why I been having a hard time understanding it. I am more into finance and banking. 😆😃

I am French and I had to find a video in English to finally understand, thank you

[@econhelp44]

Aww that's so nice thankyou. I'm really glad the video helped :)

[@lensonsoul6532]

It is interesting, I wonder when I apply this strategy into real life, how I know the number in different quaters?

[@econhelp44]

It depends! If you were considering firms as players you could use profit and assume that’s all they care about (a common assumption). For individuals you could ask how much a person would pay for an outcome, and this would give you a valuation- basically pretend everything is for purchase and nothing is for free. For instance, I would pay $50 for the rights to go for a walk, and $100 for access to the beach. Importantly, this shows that I value the beach more than the walk. With game theory the only thing that matters is how players rank different outcomes, rather than the value of the number per se, so understanding that order of preference is what we need. Does that help?

Please mma, can you pardon the introductory part of the game theory for because your voice is very clear.

[@econhelp44]

Hello! I’m so sorry but I can’t quite understand the request. Do you want me to do a video on introductory game theory? I did do this one that covers introductory topics: kzbin.info/www/bejne/aXaynYV8bKqdgbcsi=7YyJVfNMglVS1wu8. Let me know if this is what you were after!

[@sarahn3935]

Why the (price high , price high ) not a NE ? Thank you for ur amazing video

[@econhelp44]

hello, very sorry about the late reply, I had thought I answered this one. At {price high; price high} both players have an incentive to change their behaviour. At that point, either could price low and they would end up getting 40 instead of 20. Does that help?

[@curtismoxam5382]

I don't agree with the first example, why would Mike settle for 7 when he can have 8?

[@econhelp44]

Mike’s choice is conditional on what Don does. So the best response to don playing ‘down’ is for mike to play ‘down’, and get 7 rather than 6. Down is also a best response to Don playing ‘up’ since 8 is larger than 5. There is never an option of Mike choosing between an outcome where they get 7 and one where they get 8 since this depends on whether Don chooses up or down- this is not Mike’s choice to make. Does that help?

​@@econhelp44 Hi I love your videos. Thank you very much. Could you please do a video on prisoners dilemma of game theory?

[@econhelp44]

@@d.pereira2076 Yes! Here's one video that addresses some things, hopefully I will get to the other tipics soon: kzbin.info/www/bejne/gXbJYYKdmp2NsK8

[@econhelp44]

EDIT: I had a question about this that I'll reply to in this comment. Above, when I say Mike's choice is "conditional" on what Dan's does I don't mean to say that this is a sequential game. My wording wasn't great here. A better wording would be if I said "Mike's outcome (payoff) is conditional on what Don does". I think that's at the heart of the original issue. Additionally, when we consider best responses, we do think about conditional scenarios (if P1 does X then P2 will .... ) when we think about what a player will do, but this should not be thought of in terms of a sequential structure in the game, it's just representing the logic of the decision makers in the game.

I want a definite exercise I need it for my term paper and still have only 2 days, I also still cant grasp the whole material ,

[@econhelp44]

Hi, did you check out the other video, it outlines the concepts in detail? kzbin.info/www/bejne/aXaynYV8bKqdgbc , perhaps it would be good if you google for some practice questions, I'll try to put up a couple of shorts tonight that go through some examples, if I can put my baby to sleep in time! :) Good luck
