Talk:Nash equilibrium

Nash equilibrium available online
The seminal journal paper in which Nash introduces what is now called the Nash equilibrium is "Non-Cooperative Games", John Nash, The Annals of Mathematics 54(2):286-295, 1951. It is available online to for a fee at http://links.jstor.org/sici?sici=0003-486X%28195109%292%3A54%3A2%3C286%3ANG%3E2.0.CO%3B2-G (many universities subscribe to JSTOR, so this link should work for at least some people beside me)

I'm not posting that directly to the page since I'm not sure whether it's OK to post links to for-pay resources. If it is OK, then please copy this to the article page.

Well, I just did that yesterday, before reading this note. I will remove what I did right away. The article is available for a fee, but many universities and colleges provide free access to this and other for fee-services for their students.

On the other hand, referencing the article itself, without a link to the for-fee online article is probably ok. So I just took out the link to that on-line version. This way people can still find it if they want to.

Removed setence
I reverted an edit by anon, which added this setence to one section:

"choosing the best strategy given the strategies that others have chosen"

The sentence was out of context and imcomplete. If the anon would like to add it in context I'm sure it would be helpful. --Kzollman 17:59, May 11, 2005 (UTC)

Coordination game
As it turns out the entry Coordination game redirects here. Given the wide discussion of coordination games, I think it diserves its own entry. Would folks mind if I seeded the entry with the material here, and removed the redirect? thanks! -Kzollman 23:43, Jun 2, 2005 (UTC)


 * Presently, nothing links to Coordination game other than daughters of Nash Equilibrium, and both of these actually give its pay-off matrix (Mixed strategy, Pure strategy). Therefore, there can't be a problem expanding that article from a redirect.

 * Done! best --Kzollman 00:48, Jun 8, 2005 (UTC)

Fixed points
In my game theory class and text books we proved the existence of the Nash equilibrium using Kakutani fixed point theorem, a generalization of Brouwer fixed point theorem. Does anyone smarter than me know if Brower's is strong enough to prove the existence (as stated in the article)? --Kzollman 00:48, Jun 8, 2005 (UTC)


 * Okay, I fixed the proof. --best, kevin  · · · Kzollman | Talk · · · 06:03, August 2, 2005 (UTC)

Experimental Economics
Could or should we add a section on experimental results? For example there's some info (without citation) about coordination games on the experimental economics page. Can people who have more range and depth contribute more examples, etc?

PS I also feel like the sentence in the introduction about experimental economics needs citations and editing.
