The following information is the starting point for Q16 – 20. Consider an exchange economy with two agents, 1 and 2, and two goods, X and Y. Agent l's endowment is (0,10) and agent 2 's endowment is (11,0) . Agent 1 strictly prefers bundle (a, b) to bundle (c, d) if, either a > c, or a = c and b > d. Agent 2 strictly prefers bundle (a, b) to bundle (c, d) if min{a, b} > min{c, d}. For both agents, we say that bundle (a, b) is indifferent to bundle (c, d) if, neither (a, b), nor (c, d), is strictly preferred to the other. 16. This exchange economy has DSE 2014 Indox Pogo 120

Question

The question is based on 'pure exchange economy' in general equilibrium. 

Please answer all the three questions. Please do not reject it.

The following information is the starting point for Q16 – 20. Consider an exchange economy
with two agents, 1 and 2, and two goods, X and Y. Agent l's endowment is (0,10) and
agent 2 's endowment is (11,0) . Agent 1 strictly prefers bundle (a, b) to bundle (c, d) if,
either a > c, or a = c and b > d. Agent 2 strictly prefers bundle (a, b) to bundle (c, d) if
min{a, b} > min{c, d}. For both agents, we say that bundle (a, b) is indifferent to bundle
(c, d) if, neither (a, b), nor (c, d), is strictly preferred to the other.
