Suppose a world with only two persons, A and B and where only goods X and Y are available. Person A has 10 units of X and O units of Y. Person B has 10 units of X and 10 units of Y. The utility function of person A is U(X,, YA) = X,YA. The utility function of person B is U(Xn, YB) = XB TY a. Compute the contract curve b.
