Concept introduction:

Demand: Demand refers to the total value of the goods and services that are demanded at a particular price in the given period of time.

Supply: Supply refers to the total value of the goods and services that are available for purchase at a particular price in the given period of time.

Subpart (g):

To determine

Demand and supply.

Subpart (g):

Expert Solution

Answer to Problem 4P

Price shifts up and quantity indeterminate – g.

Explanation of Solution

If the supply decreases with an increase in demand, it will lead to an increase in the equilibrium price because both the curve put a pressure on the equilibrium price. An increase in demand will lead to an increase in the equilibrium quantity. This is shown below in Figure – 7:

Figure -7

In Figure -7, the horizontal axis measures the quantity supplied and the vertical axis measures the price of the balls. ‘DD’ represents the demand and ‘SS’ represents the supply curve. Due to a decrease in supply and an increase in demand, the supply curve will shift the curve to the left from SS to SS1 and the demand curve shifts the curve to the right, which leads to an increase in the equilibrium price from ‘P1 to P2’ and the equilibrium quantity from ‘Q1 to Q2’.

Answer 62

Subpart (h):

To determine

Demand and supply.

Subpart (h):

Expert Solution

Answer to Problem 4P

Price indeterminate and quantity shifts down – h.

Explanation of Solution

If both the supply and demand decreases, then it lead to a decrease in the equilibrium quantity and the change in equilibrium price is indeterminate. This is because a decrease in supply puts an upward pressure on the equilibrium price. This is shown below in Figure – 8:

Figure -8

In Figure -8, the horizontal axis measures the quantity supplied and the vertical axis measures the price of the balls. ‘DD’ represents the demand and ‘SS’ represents the supply curve. Due to a decrease in supply and a decrease in demand, the supply curve will shift the curve to the left from SS to SS1 and the demand curve shifts the curve to the left, which lead to an increase in the equilibrium price from ‘P1 to P2’ and a decrease in the equilibrium quantity from ‘Q1 to Q2’.
