Backwards Induction Game Tree

[@leohuo4263]

The most useful expanation about sequential game theory ever. Explained the logic better than my lecturer who spent 2 lectures trying to make us understand

[@Dgaf001]

Amazing! You just explained in less than 10 minutes what my professor could not in 1 month! Thank you!

[@casperdushane6880]

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

[@jasonjackson4555]

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.

[@evanchong3158]

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!!!

[@michellelim3676]

I watched this and the other video explaining the nash equilibrium... it was so clear and easy to understand this complicated games thing after me reading my textbooks over and over. Thank you so much!!! You are a legend

[@raskand1977]

Hi Ashley, I have really appreciated your videos this weekend. I am sitting here reading all the articles out there, but you just totally nail it in eight and half minutes. Thank you so much!

[@dbrown4126]

Excellent teacher, you are!!! You took a complex model, for those not used to these ideas, and explained it efficiently, simply, and expertly! Thank you.!

[@mitraBaha]

Thank you so much Ashely. I watch too many videos in this subject, but I did not learned. After watching this video, I learned it in 5 minutes. You are awesome!

[@ittisaftamim]

Finally found a video to understand Subgame perfect Nash Equilibrium. Must see for anyone who is having trouble understanding SPNE. Thanks a lot, Ashley :)

[@matthewhecht6580]

It hard to express my word of thanks in writing to you. You make game theory understandable.

[@e02100]

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 KZbin 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!!!!

[@maliamungubenard1896]

Who else hits the like button even before watching? Your the best tutor ever

[@strategyschool]

Amazing, clean explanation. Hodgson has one of the best channels about Game Theory & Econ. in this patform.

[@ahooramazda6627]

Dead simple and practical explanations as always. Thank you!

[@23heavenbliss]

i am preparing my exam rn and this video help a lot!! thank you, Ashley

[@attuneflows3539]

i just want to thank you so much for saving my grades, truly

[@kennythemasseuse]

Thanks, this really helped as its a quick and immediate dive into backward induction

[@shannongovers]

Great video, short to the point and explained really well!

[@stephenponin1165]

best presentation love it saved my day

[@akankshabassi2428]

Thanks by far the best video for the topic

[@EdvinPalmer]

Excellent explanation. Thank you so much!

[@malenawong167]

Love the harry potter analogy! made it way easier to relate!

[@SamEbby]

this was JUST PERFECT! thank you I needed to know this for my final in game theory this week I was struggling but THIS video finally made sense to me the internet is wonderful thank you for making this

[@dhekrabensassi1769]

Thank you for this clear explanation. Can we use backward induction to resolve Stackelberg in 3 players extensive form game?

[@AshleyHodgson]

Yes. Backwards induction is the way to approach Stackleberg (Quantity Leadership) Oligopolies, no matter how many firms. kzbin.info/www/bejne/eKKkp4SNfs6fp80&ab_channel=AshleyHodgson

[@dhekrabensassi1769]

@Ashley Hodgson thank you. Have you an example in extensive form game with 3 players? I mean a tree like the exemple of Ginny, and Voldemet and Harry where we want to find stackelberg equilibrium. If you have an exemple I will be grateful if you share it with me.

[@marioshamhon2809]

You are awesome thank you for helping me understand this before my final I love the harry potter example by the way

[@GradStudentTutorials]

Amazing video! Thank you so much. Your explanations are very clear.

[@muzombo3334]

Thank you for your video I will make my examen tomorrow I hope it's going to help me !!

[@shrawanipal]

This is amazing, thank you!

[@PunmasterSTP]

You're a wizard Ashley!

[@owencaulfield]

This video truly saved me

[@matania21]

Very helpful ! Thanks for the very clear lecture

[@_hridhima]

This was so so amazing. Really helped me. Thanku!

[@dfdfgdfkih]

This video is really helpful. Thanks Ashley

[@JonSnow-qj5pl]

Is final outcome of backward induction in Nash equilibrium . If yes , is it sub game perfect nash equilibrium too ? Ur writing is beautiful btw :))

[@muhammadkhairiaimran6218]

great video, my only question is how it the values of the payoff being determined? Unless it's totally random for this learning video.

[@geraudeakakpo3544]

Thank you so much for this good explanation!

[@paulino4170]

Great video! Thank you!

[@dumimabhena3460]

This was very helpful. Thank you!

[@angelinelyn8162]

i am so happy thank you so much...this was so easy to understand

[@basicbot7349]

wow, you made this so easy

[@EthanHalfhide]

I would love to understand the algorithm behind the values

[@NJK2025]

thank you again Dr. Hodgson

[@danielameti7221]

Brilliant explanation!

[@wiktorias58]

Great explanation, thank you!

[@maliamungubenard1896]

May God bless you abundantly

[@SosoKoko21]

Thanks a lot, this is really great :)

[@АнаБуљешевић]

Very well explained. Can spmeone recommend video where you have this decision tree transformed into matrix? Like big table...

[@ayeshahanif4770]

How to draw this tree from theory ??

[@ahmedbassyounyshehab4258]

thank you , finally understand tree game

[@mikecolerone770]

very useful, thanks a lot!

[@rakibulislamarafat6970]

This is amazing!!!!. Thank you!

[@TatianaJaramillo-he8nt]

Great video thank you so much

[@amalzahra578]

This is so great!!!

[@oghenefejiroagbi1469]

What happens when there is indifference between one of the two terminal histories .?

[@poladyusifli2959]

Great video! Thank u

[@Yong.q]

Good explanation!

[@akhilchanana8824]

Amazing, thankyou for your help !

[@a.b.c.d.e...]

The second example shouldve containted a tie to express the fact that sometimes there are multiple backward induction solutions.

[@andersonanjo5388]

Very very helpful. Thank you.

[@shlomozerbib388]

I m wondering if the results would be the same if the game order between the players is changed...

[@AshleyHodgson]

No, it would not necessarily be the same.

[@Audry_budo]

Thank you!😭🫶🏾

[@NILESHKUMAR-vg6gl]

What if ? The end node player is indifferent between two strategies..

[@experiencelifelittleone]

thank you! So helpful!

[@wahyuwicaksono4730]

how we make point for every move. thanks.

[@Luckygirlintheworld]

Thank you soooo much for saving my brain😂😂😂😂

[@deekshanshvardhan4976]

is this nash equilibrium we are getting?

[@haktat]

Very helpful. thank you

[@kirillholt2329]

What if at the last fork player 2 has two equal outcomes ? Let's say (... , 0) (... , 5) and (... , 5) you would crosso out one with 0 but then what ?

[@apaew8560]

Thank you so much

[@alanl5832]

Clear, thank you

[@doingmything93]

Awesome!

[@AlaaHosaen-d9i]

Please I need books about sequential game please

Thanks I get u madam Love youuu

[@josephsmyth832]

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]

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.

[@EthanHalfhide]

how are the numbers calculated?

[@Grey_mind]

I love you

[@fffsadfy]

marry me ?

[@hyuming2577]

One more note from this video guys -- > she loves Harry Potter.😝😝

[@danielsaunders4058]
