Game Theory 101 (#74): Perfect Bayesian Equilibrium

This lecture begins a new unit on sequential games of incomplete information. Perfect Bayesian equilibrium is the gold standard solution concept for these games. This lecture gives the definition and explains where it gets its core components. Future lectures will show PBE in action. Look further down the playlist if you are trying to find an explanation of pooling equilibrium, separating equilibrium, or semi-separating/partially pooling equilibrium.

You are literally saving my degree! I always leave the lecture hall confused, but I get it after your videos.

Watched entire playlist in 3 days. Great videos. I used the textbook A Guide to Game Theory by Fiona Carmichael along side these videos.

This makes things clearer than my uni lecture

So, how do you solve the perfect bayesian equilibrium? - same way as the bayesian nash equilibrium?

Please what of getting sequential equilibrium and perfect equilibrium in extensive form game with incomplete information. I really need help with that

[albertchen]

One critical question: is there any general method to estimate the payoff functions of a linear combination of state variables from field data? Are the coefficients from logistic regression acceptable? My concern was that this approach is to maximize likelihood without any game procedure inside. Also the mixed strategies probability should be different from the distribution of real data.

Hi, there is no bayesian equilibirum in your book. Where can I find a written version?

[nottt]

Hey how come no evolutionary game theory in game theory 101?

[pooplordpoopsen]

Man I cant tell you how much I hate bayesian stuff. Already hated it during Logic. xD

Sequentially rational? More like “Snap, this is unbelievable!” At the beginning of this series, I had no idea how advanced (and cool) things would get!

please your email i want to ask about something on bargaining game, Best Regards

game theory's colloquialism's are so unnecessarily convoluted. it's laughable.
