Suppose A lexicographically prefers a to y and B considers and y to be perfe substitutes, i.e., between bundles (x, y) and (x', y'), she strictly prefers (x, y) if an only if a +y>' + y'. The competitive equilibrium allocation for this economy is (A) A gets (0,1) and B gets (2,0) (B) A gets (2,0) and B gets (0,1) (C) A gets (3/2,0) and B gets (1/2,1)) (D) * A gets (1,0) and B gets (1.1)
