Respond to the question: Investment Game 4 players Two decision?

01/18/2014 05:50 AM by Dominik; Investment Game. 4 players. Two decisions each. Nash Equilibira?
 Hello,

I try to calculate the nash Equilibria for a relatively complex investment game. There are four players and each player has to decide how much she wants to invest into a and b. Alle player start with the same endowment E = 100. a and b are continuous variables with (a+b) >= 100. (side condition)

Please see the attached file for the payoff condition.

Do I have to start with a Lagrange Function? With respect to which variables do I have to differentiate? (a1, a2, a3, a4?) The term gets really really ugly.

THX, a lot!

(Sorry, double post!)
