Downloadable versions (see mov or mp4 link just under the on screen viewer) usually have a menu; these are mostly screen capture and coordinated audio, with some overlays of class interaction (voyeuristic, but sometimes a little slow compared to lecture style...)

John Fountain strategic,economics en John Fountain John Fountain We introduce the idea of a sub game perfect Nash Equilibrium analyzing the entry deterrence game as a simultaneous game to show how there might be several Nash Equilibria but only one sub game perfect one...(ie one that sustains repeated questioning about rational behaviour in every possible sub game of the original game - eben sub games where you don't eve expect to be) . Looked at this way there turn out to be several Nash Equilibria...not all of which are "reasonable". The latter part of the class introduces a simple card game as we begin a new section on games of imperfect information.

In particular how does the rollback equilibrium idea connect with Nash Equilibrium concept? We analyze sequential games as simultaneous games, and vice versa, dig a bit deeper into the concept of Nash Equilibrium, then introduce information sets as a way of analyzing simultaneous games as sequential games Thu, 25 Oct 2007 04:14:00 GMT http://strategicecon.com/modules/journal/entry.php?space_key=1&module_key=4&post_key=23 http://strategicecon.com/viewfile.php/users/49/4/GameTheory2007/wk0607lecture11.mp4 Simultaneous games, cont'd. After much confusion over the payoffs in the class example at the end of lecture 9, I introduce a slightly easier version of the minimum effort coordination game, and we spend most of the class walking through the analysis of this game and the problem of coordination ( eg in joint or team work) that it is designed to shed some (strategic) light on. Then a quickie, further extension of the Prisoner's dilemma to 3 players.(more exam oriented than practical extensions to many players - will fix up in 2008) Mon, 15 Oct 2007 20:27:00 GMT http://strategicecon.com/modules/journal/entry.php?space_key=1&module_key=4&post_key=19 http://strategicecon.com/viewfile.php/users/49/4/GameTheory2007/wk0507lecture10.mp4 Simultaneous games, cont'd. We introduce "best response" type reasoning in simultaneous games, compare it with "dominance" reasoning, then use it to introduce the key idea of Nash Equilibrium. Then we use it to examine an important strategic tension in coordination games, starting with simple 2x2 coordination games: pure coordination, assurance, battle of the sexes, chicken. The class ends introducing the minimum effort coordination game.

We analyze the idea of dominance reasoning and extend it from 2x2 to a more complicated voluntary contributions mechanism game (give all none or various levels in between) and to games where not every player has a dominant strategy, introducing a new idea: iterated elimination of successively dominated strategies.

The lecture starts with a classroom game, the "voluntary contributions mechanism" [think supporting community projects via matching grants], then introduces a 2x2 payoff table to analyze this game and introduce dominance reasoning; finish with the classic prisoner's dilemma Sat, 13 Oct 2007 04:35:00 GMT http://strategicecon.com/modules/journal/entry.php?space_key=1&module_key=4&post_key=12 http://strategicecon.com/viewfile.php/users/49/4/GameTheory2007/wk0407lecture7.mp4
