Efficiency refers to minimizing the price paid by buyers; equality refers to maximizing the gains
from trade
among buyers and sellers.
c.
Efficiency refers to maximizing the size of the pie; equality refers to producing a pie of a given
size at the
least possible cost.
d.
Efficiency refers to maximizing the size of the pie; equality refers to distributing the pie fairly
among
members of society.
23.
If an allocation of resources is efficient, then
a.
consumer surplus is maximized.
b.
producer surplus is maximized.

all potential gains from trade among buyers are sellers are being realized.

the allocation achieves equality as well.
24.

raise total surplus.
c.
lower producer surplus.
d.
raise producer surplus but lower consumer surplus.
25.
Which of the following is correct?
a.
Efficiency deals with the size of the economic pie, and equality deals with how fairly the pie is
sliced.
b.
Equality can be judged on positive grounds whereas efficiency requires normative judgments.

Efficiency is more difficult to evaluate than equality.
d.
Equality and efficiency are both maximized in a society when total surplus is maximized.
