DSE 2016 Question 21: Welfare economics and social choice
Consider an exchange economy with two agents, 1 and 2, and two goods, X and Y. There are 6 units of X and 4 units of Y available. Agent 1 has the utility function u1=min{x1,y1} and agent 2 has the utility function u2=x2+y2.
Which of the following allocations is not Pareto efficient? (Each allocation is agent 1's bundle followed by agent 2's bundle.)

Plain-text version
Consider an exchange economy with two agents, 1 and 2, and two goods, X and Y. There are 6 units of X and 4 units of Y available. Agent 1 has the utility function u₁=min {x₁,y₁} and agent 2 has the utility function u₂=x₂+y₂. Which of the following allocations is not Pareto efficient? (Each allocation is agent 1's bundle followed by agent 2's bundle.) (A) (2,0),(4,4) (B) (4,4),(2,0) (C) (2,2),(4,2) (D) (0,0),(6,4)
Also written as: Consider an exchange economy with two agents, 1 and 2, and two goods, X and Y. There are 6 units of X and 4 units of Y available. Agent 1 has the utility function u_1=min {x_1,y_1} and agent 2 has the utility function u_2=x_2+y_2. Which of the following allocations is not Pareto efficient? (Each allocation is agent 1's bundle followed by agent 2's bundle.)
