I suggest you click on the "Reverse Sort Order " text/link in blue in the right hand menu bar (top right) to see clips in chronological) orderEach clip is about 50 minutes. 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 This lecture continues our discussion and analysis of strategic interaction with asymmetric information and uncertainty. We examine the problem of adverse selection and the "lemons" problem (why is the used car you buy likely to be a "lemon"?) . Here, bad quality products drive out good quality products. Next we look at attempts to solve the lemons type problem: can uninformed buyers find tests or screens to help resolve their uncertainty? Can privately informed sellers provide signals like warranties or certification reports that buyers will believe?

We start reviewing and re-explaining the natural frequency & truth table ideas about basic technological and diagnostic uncertainties in the venture capitalist game. Then we sketch the game tree here, concentrating on using information sets to help us set out what the players know and don't know in the game, and what they know and don't know about what other players know and don't know..etc....Then we try to figure out : what's it reasonable to believe in a game like this? Here we use our previous ideas about player's strategies to help use our beliefs about diagnostics and technologies to help figure out what should I believe here? Naturally the answer is complicated...but the intuition is worthwhile, coz we run smack into the problem of multiple reasonable things to believe...and "bad" equilibria...all because of private information. Two examples: why men in NZ are reluctant to enter into primary care education, why career oriented women may have a tough time finding good jobs.

Then we start a new topic : games of imperfect and asymmetric information. Here, uncertainty remains a key feature, but different agent's have different uncertainties, or put another way, different agent's have different bits of private information that might be relevant to the game. We set up a venture capitalist example from Kreps' Microeconomics for Managers in the latter half of this lecture (for this and the next lecture) Thu, 25 Oct 2007 04:25:00 GMT http://strategicecon.com/modules/journal/entry.php?space_key=1&module_key=4&post_key=30 http://strategicecon.com/viewfile.php/users/49/4/GameTheory2007/wk0907lecture18.mp4
