Question
3. Anita (A), Ben (B) and Carlos (C) are housemates who have moved to a new house and
must decide how to allocate rooms X, Y and Z.
An 'allocation' is where each housemate is assigned to exactly one room. For example,
Anita → Room Z, Ben → Room X and Carlos → Room Y is allocation (Z, X, Y).
Utilities for each room are given below:
Room X
Utility for A
7
Utility for B
9
Utility for C 2
Room Y
4
3
7
Room Z

Utilities for each room are given below: Room X Utility for A 7 Utility for B 9 Utility for C 2 Room Y 4 3 7 Room Z 2 1 4
(d) Which of the Pareto optimal allocations maximise total surplus (utility) and
would all housemates weakly prefer this allocation over any other?
(e) Suppose the housemates decide to allocate the rooms by randomly assigning Room
X to someone, Room Y to someone and Room Z to someone. Explain whether this
always leads to an allocation which is Pareto optimal or maximises total surplus.
(f) Suppose the housemates decide to allocate the rooms according to the 'random
serial dictatorship' rule studied in lectures.
Explain what this rule is and whether in this case it always leads to an allocation
which is Pareto optimal or maximises total surplus.
