A major video gaming platform increases its monthly subscription price from £12.00 to £15.00. In response, the monthly sales of a partner headset brand decrease from 8,000 units to 6,800 units.
Calculate the cross-elasticity of demand (XEDXEDXED) for the headsets with respect to the subscription price, and identify the economic relationship between these two goods.
XED=−0.6XED = -0.6XED=−0.6, indicating they are complements
XED=+0.6XED = +0.6XED=+0.6, indicating they are substitutes
XED=−1.67XED = -1.67XED=−1.67, indicating they are complements
XED=−0.6XED = -0.6XED=−0.6, indicating they are substitutes
