If preferences satisfy all requirements, is A preferred to C or C to A? Explain your answer.
A
B
C
Basket A has more food than basket C.
Basket C has more clothing than basket A.
Therefore, basket A and C cannot be compared without additional information.
1b. An island economy produces only two goods – coconuts and pineapples. There are five
people (A, B, C, D and E) living on the island, with these preferences:
A has a strong preference for
pineapples. B has a strong preference
for coconuts.
C doesn’t care for pineapples (assigns no value to them).
D doesn’t care for coconuts (assigns no value to
them).
E will only consume pineapples and coconuts in the fixed proportion of one pineapple to one
coconut.
For each of these five individuals, construct a representative indifference curve
with pineapples on the horizontal axis and coconuts on the vertical axis.
