Only individuals A and B live on a desert island where no production is possible. A is endowed with 12 units of good X and 18 units of good Y. B is endowed with 6 units of good X and 42 units of good Y. In the Edgeworth box, good X is measured on the horizontal axis. Individual A's utility function is
so her MU
X = 3Y and her MU
Y = 3X. Individual B's utility function is UB = 10
so his
and his MU
Y = 5
