Question

BASED ON THE INFORMATION BELOW WHAT IS THE ECONOMIC PRICE

Suppose demand and supply are given by Qd = 50 - P and Qs = 0.5P - 10.

a. What are the equilibrium quantity and price in this market?

Equilibrium quantity: 10

Equilibrium price: $ 40

b. Determine the quantity demanded, the quantity supplied, and the magnitude of the surplus if a price floor of $46 is imposed in this market.

Quantity demanded: 4

Quantity supplied: 13 Surplus: 9

c. Determine the quantity demanded, the quantity supplied, and the magnitude of the shortage if a price ceiling of $30 is imposed in the market.

Also, determine the full economic price paid by consumers.

Quantity demanded: 20

Quantity supplied: 5 Shortage: 15

Explanation / Answer

Full economic price is the price such that Quantity demanded = 5 units = Quantity supplied

therefore 5 = 50 - P

             P = 50 - 5

             P = $45
