Question 56

An electronics manufacturer monitors the sales of its premium VR headsets (HHH) and compatible VR gaming titles (GGG). Following a 15% reduction in the price of VR headsets, the quantity demanded of VR gaming titles increases by 12%, while the quantity demanded of a rival's standalone console (CCC) decreases by 9%.

Which of the following correctly identifies the economic relationships between these goods and their corresponding cross-price elasticities of demand (XEDXEDXED)?

A

HHH and GGG are complements with XEDHG=−0.8XED_{HG} = -0.8XEDHG​=−0.8, while HHH and CCC are substitutes with XEDHC=+0.6XED_{HC} = +0.6XEDHC​=+0.6.

B

HHH and GGG are substitutes with XEDHG=+1.25XED_{HG} = +1.25XEDHG​=+1.25, while HHH and CCC are complements with XEDHC=−1.67XED_{HC} = -1.67XEDHC​=−1.67.

C

HHH and GGG are complements with XEDHG=−1.25XED_{HG} = -1.25XEDHG​=−1.25, while HHH and CCC are substitutes with XEDHC=+1.67XED_{HC} = +1.67XEDHC​=+1.67.

D

HHH and GGG are substitutes with XEDHG=+0.8XED_{HG} = +0.8XEDHG​=+0.8, while HHH and CCC are complements with XEDHC=−0.6XED_{HC} = -0.6XEDHC​=−0.6.
