[AS]

Suppose there are 3 alternatives x,y,z and four individuals 1,2,3,4

R1=(xy)z
R2=yzx
R3=z(xy)
R4=(xy)z

then set of pareto-optimal alternatives isa

a. x.y
b  x,z
c  y,z
d  none

[akanksha]

the ans should be b
y,z

[AS]

could you explain?........

[mrittik]

x & y are same preference for 2....and 1 has z...1 has y....so y,z

I think z is the only Pareto efficient allocation as if we deviate from z to:
y then 1,2,4 are all better off but 3 is worse off
x then 1nd 4 are better off but 2 and 3 are worse off
But when we take y as allocation and deviate to:
x then 1,2,3 will be indifferent and 2 will better off!
z then 2 and 3 will better off and 1nd 4 will worse off
