Dear Chaminda,

I am attaching two examples of games theory in the international sphere. The first file is from Gibbons 1992 book, Princeton Press about tariff applications under imperfect market assumptions. The second is from an article I co-authored that uses game theory in a Computative General Equilibrium (CGE) setting. Hope you find them useful.

Please note that when you are modelling international economies, you will have to control for the Rest of the World (ROW). My example on CGE does that.

Dear Lall

Thanks lot for your great help. Now I am following sources that you have sent 

My advice would be "Game Theory "by D. Fudenberg and J. Tirole (MIT Press).

However, to start with the subject I suggest Thinking Strategically by A. Dixit and B. Nalebuff (Norton) or "A primer in game theory" by R. Gibbons (Prentice Hall)

Dear Carlos Hervés 

Thanks lot
