Question

Suppose demand and supply are given by Q^d =60 - P and Q^S = P-20. a. What are the equilibrium quantity and price in this market? Equilibrium quantity: Equilibrium price: $ b. Determine the quantity demanded, the quantity supplied, and the magnitude of the surplus if a price floor of $50 is imposed in this market. Quantity demanded: Quantity supplied: Surplus: c. Determine the quantity demanded, the quantity supplied, and the magnitude of the shortage fa price ceiling of $32 is imposed in the market. Also, determine the full economic price paid by consumers. Quantity demanded: Quantity supplied: Shortag e: Full economic price: $

Explanation / Answer

Supply function: Q = P-20

and Demand Function: Q = 60-P

(a) Equilibrium price and quantity can be identified by equating the above two function:

P-20 = 60-P

2P = 80

P = $40

and Q = 60 - (40) = 20 units

equilibrium quantity is 20 units and equilibrium price is $40.

(b) If price floor is imposed in the market at $50, it implies no seller will be allowed to sell the product below $50 per unit, thus supply quantity would be = P - 20 = 50-20 = 30 units

and quantity demanded would be = 60 - P = 60 - 50 = 10 units.

quantity demanded and supplied does not match at this price floor. supply is greater than demanded, thus a surplus occurs.

Magnitude of surplus = supply - demand = 30 - 10 = 20 units.

(c) If price ceiling of $32 is imposed it implies no seller would be allowed to sell above $32 price per unit.

thus supply quantity would be = P - 20 = 32-20 = 12 units

and quantity demanded would be = 60 - 32 = 60 - 32 = 28 units.

quantity demanded and supplied does not match at this price floor. Demand is greater than supply, thus a shortage occurs.

Magnitude of shortage = Demand - Supply = 28 - 12 = 16 units.

Full economic price (PF) = Pc + (PF - PC) where

PF = full economic price

PC = price ceiling

PF - PC = nonpecuniary price

12 = 60 - PF

PF = $48.
