Play Video		 Lecture 3: Sequential Games, 1 of 3
Logical structure to a game (PDIP), simple 2x2 game tree and rollback reasoning (backward induction), interpreting the concepts of a startegy and of payoffs...

Play Video		 Lecture 4: Sequential Games, 2 of 3
Analysing a simple 2x2 entry deterrence game, connecting it with Kreps' basic Threat game: why should you (not) believe a threat when it involves mutual harm.
Lecture 6
Supplement to Lecture 4: Interpreting Payoff numbers
Play Video		 Supplement to Lecture 4: Interpreting Payoff numbers
A short 8 minute clip on how to question and interpret the payoff numbers "utilities" used in game theory reasoning. This is an excerpt from a previous years lecture in Econ 223..

Play Video		 Lecture 6: Simultaneous Games, 1 of 4 - Donation to Public Goods
#1 of 4 lectures on simultaneous games; a "chatty" lecture, includes a classroom game about charitable contributions...and why they might not be as forthcoming as one would hope. Introduces dominance reasoning and the prisoner's dilemma concept.
Lecture 9

Play Video		 Lecture 7: Simultaneous Games, 2 of 4 - Dominance reasoning in VCM game
The second of 4 lectures on simultaneous games - we review the short version of the VCM game then extend it - if people have the choice of giving "some" rather than none or all..what would we expect?

Lecture 11
How can such a bad outcome be a Nash Equilibrium
Play Video		 How can such a bad outcome be a Nash Equilibrium
This is a supplement t lecture 8 2009, based on questions students had after class: how can this be an equilibrium when there is something else better for both in the game?"this" was the outcome of sequential elimination of dominated strategies and also of best response reasoning. Once you get the logic here you'll see one of the strategic tensions of the prisoner's dilemma in a completely different game....
