Calculating Cross Elasticity of Demand: Easy Economics 3-Step Process

This video tutorial explains how to calculate the cross elasticity of demand using a three-step process. It introduces the formula for cross elasticity, demonstrates the calculation through examples of substitute and complementary goods, and emphasizes the importance of selecting relevant data. The tutorial concludes by reinforcing the ease of applying the three-step process to calculate elasticities.
