Question

Rice and potatoes are substitutes in consumption. If the price of rice rises and there is a bumper crop of potatoes, in the market for potatoes one would expect the equilibrium price to _____ and the equilibrium quantity to _____.

a) equilibrium price to rise, fall, or stay the same and equilibrium quantity to rise.
b) equilibrium price to rise and the equilibrium quantity to fall.
c) equilibrium price and quantity both to fall.
d) equilibrium price to rise and the equilibrium quantity to fall, rise, or stay the same.

Answer 1

a) equilibrium price to rise, fall, or stay the same and equilibrium quantity to rise.

Step-by-step explanation:

Substitute goods are goods that can be used in place of each other.

If the price of rice rises, consumers shift to the consumption of potatoes. Price and quantity demanded of potatoes increases

The bumper harvest increases supply of potatoes. Price falls and quantity increases.

The effect on equilibrium quantity of potatoes would be indeterminate but equilibrium quantity would rise.
