Answer:
Almonds and walnuts are substitutes. Suppose the demand for walnuts increases from a
rise in world demand.
a. Using partial equilibrium analysis, predict what happens to the equilibrium price and
quantity of almonds.
b. Using general equilibrium analysis, explain how the feedback effects between the
markets affect the almond market. Does general equilibrium analysis predict a larger or
smaller effect on the equilibrium price and quantity of almonds than partial equilibrium
analysis?
Answer:

B) q1 = 350; q2 = 275
C) q1 = 80; q2 = 106
D) q1 = 260; q2 = 245

A) 102.
B) 88.
C) 56.
D) 22.
