(a) Previously, we found the Nash equilibrium for the
game. Now find the collusive outcome. What total quantity should be set by the
two countries in order to maximize their joint profit?

(b) Suppose the two countries produce equal quantities of
VLCCs, so that they earn equal shares of this collusive profit. How much profit
would each country earn? Compare this profit with the amount they would earn in
the Nash equilibrium.

(c) Now suppose the two countries are in a repeated relationship.
Once per year, they choose production quantities, and each can observe the
amount its rival produced in the previous year. They wish to cooperate to
sustain the collusive profit levels found in part (b). In any one year, one of
them can defect from the agreement. If one of them holds the quantity at the
agreed level, what is the best defecting quantity for the other? What are the
resulting profits?

(d) Write down a matrix that represents this game as a
prisoners’ dilemma.

(e) For what interest rates will collusion be sustainable
when the two countries use grim (defect forever) strategies?
