Suppose the quantity of gadgets demanded is reported to have fallen by 20 units—from 50 to 30 units—as a result of a per-unit-price increase in widgets from $10 to $14, what is the cross-price elasticity of demand? Explain your cross-price elasticity coefficient and graphically show and explain the consumer responses in both markets. As a manager, carefully explain why your estimated coefficient may or may not influence your pricing decision in this case.
