Question

1. XYZ Corporation is a manufacturer of widgets. Over the past several months, it has been selling its widgets for $100 each and unit sales have averaged 5,000 units per month. This month its competitor, ABC, Inc. raised the price of its widgets from $100 to $110. XYZ noted that its unit sales increased by 200 units. Please answer part B


a. What is the cross price elasticity of demand between XYZ%u2019s and AB C%u2019s widgets?

We know this is .4
b. If XYZ knows that the price elasticity of demand for its widgets is -2.0, what price would XYZ be able to charge and still sell 5,000 widgets, assuming ABC keeps its price at $110?


Explanation / Answer

a) dP = 10

dQ = 200

(P1 + P2)/2 = (100+110)/2 = $105 ;

(Q1+Q2)/2 = (5000+5200)/2 = 5100 ;


Elasticity = (dQ/dP)*(P/Q) = 0.4111;


b) (dQ/dP)*(P/Q) = - 2 ;

P /dP = -2*Q/dQ ;

Q = 5100 ;

dQ = 200 ;

P/dP = -51

(P1+P2)/2 = -51*(P2-100)

100 + P2 = -102*P2 + 10200

103*P2 = 10100

P2 = $98.058
