Solution Summary: The author explains the three fair divisions of the land using the lone-divider method.
Five players are dividing a cake among themselves using the lone-divider method. After the divider
D
cuts the cake into five slices
(
s
1
,
s
2
,
s
3
,
s
4
,
s
5
)
the choosers
C
1
,
C
2
,
C
3
, and
C
4
submit their bids for these shares.
a. Suppose that the choosers’ bid lists are
C
1
:
{
s
2
,
s
3
}
;
C
2
:
{
s
2
,
s
4
}
;
C
3
:
{
s
1
,
s
2
}
;
C
4
:
{
s
1
,
s
3
,
s
4
}
Describe three different fair divisions of the land. Explain why that’s it—why there are no others.
b. Suppose that the choosers bid lists are
C
1
:
{
s
1
,
s
4
}
;
C
2
:
{
s
2
,
s
4
}
;
C
3
:
{
s
2
,
s
4
,
s
5
}
;
C
4
:
{
s
2
}
Find a fair division of the cake. Explain why that’s it—there are no others.
