moochpuppy Posted November 5, 2003 Share Posted November 5, 2003 I thought I remember seeing one or two of you and was wondering if you could answer this question: In game theory, when trying to find Nash Equilibria, it does not exsist if there is unilateral profitable deviation. But does it exsist if both players have profitable deviation? Thanks. Quote Link to comment Share on other sites More sharing options...

Sounds to me like it would be possible, not extremely likely, but possible, as long as the peoples optimal profits perfectly aligned with what the other party wanted to do.

But that is just off of the top of my head. It has been 10 years since I had Micro... Well, on my e-mail to my professor I asked: "So if there is profitable deviation in the profile then it can't be Nash Equilibria?" He responded by adding "unilateral" between profitable and deviation and then typed exactly after my question. This would lead me to believe then that if both players had profitable deviation as opposed to unilateral, then Nash Equilibria is present in the profile.

Steff Posted November 5, 2003 Share Posted November 5, 2003 Yes, and yes. Or, yes and no. Or, no and yes. Or, no and no. Hope that helped Quote Link to comment Share on other sites More sharing options...
rafacosta Posted November 5, 2003 Share Posted November 5, 2003 But does it exsist if both players have profitable deviation? I think it's no. Nash equilibrium means that the players dont wanna get out of their choice because they chose what was the best for them. If they have profitable deviation, they wanna get out of their choice. It's hard to explain in english. Quote Link to comment Share on other sites More sharing options...
SuperSteve Posted November 5, 2003 Share Posted November 5, 2003 I am in a macroeconomics class, it is so boring. I do not know how I ended up in it, but I suck at it. I think it would help to attend every class though. Quote Link to comment Share on other sites More sharing options...
ChiSox_Sonix Posted November 6, 2003 Share Posted November 6, 2003 Principals of Microeconomics. i took macro and micro, but little "knowledge" i received in those classes remains, lol Quote Link to comment Share on other sites More sharing options...
DBAHO Posted November 6, 2003 Share Posted November 6, 2003 I did Economics last year, but not enough ppl at my school wanted to do it this year so I couldn't do it. Got no idea about Macro and Micro Economics, that's a bit too advanced for me. We only did Supply and Demand, Interest Rates, Inflation, u know ur basic Economics stuff.

southsider2k5 Posted November 6, 2003 Share Posted November 6, 2003 Are you asking about if it is pareto optimal? pareto optimal has more to do with price pointing in individual markets and companies. This is different. Quote Link to comment Share on other sites More sharing options...

You can use optimal pareto in game theory. One player will be in a better situation only if the other will be in a worst situation. Quote Link to comment Share on other sites More sharing options...

Yes, if a profile has profitable unilateral deviation then it doesn't contain Nash Equilibria (that we knew) but if it contains profitable bilateral deviation, it's irrelevant, so then it also contains no Nash Equilibria.
