Answers may include:

  • definition of cross price elasticity of demand (XED)

  • explanation of the impact of XED on businesses if the price of complements and substitutes for a good they produce changes in terms of price, quantity, revenue and profit

Evaluation may include: the relative size of XED and the extent to which the revenue and profit will rise or fall; the assumption that other factors affecting demand remain constant and that XED is difficult to predict and measure.
