Question #89564

Maple Leaf Cement Factory Limited is

a reputable largest manufacturer of cement in Pakistan. The company was set up in

1956. Suppose the quantity demanded and quantity supplied functions of cement

industry in starting week of current month are:

Qd = 5000-6P

Qs= 1500+P

Where ‘P’ is the price in rupees per bag of cement and ‘Qd’ is quantity demanded of

cement in number of bags. ‘Qs’ is quantity supplied of cement in number of bags.

Requirements:

a. Calculate the market equilibrium level of price and quantity.

b. Calculate price elasticity of demand using point elasticity method when the

company is in equilibrium and interpret the result.

c. What will happen to supply of cement, equilibrium price and equilibrium

quantity of cement if government gives subsidy to cement manufacturers?

quantity of cement if government gives subsidy to cement manufacturers?

Expert's answer

a. The market equilibrium level of price and quantity are:

Qd = Qs,

5000 - 6P = 1500 + P,

7P = 3500,

P = 500,

Q = 1500 + 500 = 2000 units.

b. Price elasticity of demand using point elasticity method is:

Ed = -6×500/2000 = -1.5, so the demand is elastic.

c. If government gives subsidy to cement manufacturers, then supply of cement will increase, equilibrium price will decrease, and equilibrium

quantity of cement will increase.
