Technical Questions
Using the elasticity table (above), you have the following information for your product: (1) The price elasticity of demand is -2.0; (2) The income elasticity of demand is 1.5; and, (3) The cross-price elasticity of a related good is -3.5. What can you determine about consumer demand for your product from this information?â¨â¨
