  3. Consider an exchange economy with two agents, 1 and 2, and two goods, X and Y. Each agent's consumption set is R2+. The endowments of agents 1 and 2 are (10,1) and (0,9) respectively. (In any commodity bundle, the first entry is a quantity of X and the second one is a quantity of Y.)

    If a > c, or a = c and b > d, then Agent 1 strictly prefers bundle (a, b) to (c, d).

    If b > d, or b = d and a > c, then Agent 2 strictly prefers bundle (a, b) to (c, d).
