Elasticity Computations

1. Suppose that 50 units of a good are demanded at a price of $1 per unit. A reduction in price to $0.25 results in an increase in quantity demanded to 70 units. Show that these data yield a price elasticity of 0.25. By what percentage would a 10 percent rise in the price reduce the quantity demanded, assuming price elasticity remains constant along the demand curve?

Given:

Q1 = 50

Q2 = 70

P1= 1

P2 = .20

What percentage would a 10 percent rise in the price reduce the qd?

Ep = Q2-Q1/P2-P1 = 70-50/.20-1 =20/.80 = -0.25

A 10% increase in price would result to 25% reduction in the quantity demanded.

2. Fill in the blanks.
