Meaning
Economic coefficients measure the responsiveness of the demand for one product when the price of another product changes. Calculating cross elasticity allows a brand manager to determine if two items in a category are substitutes or complements in the eyes of the buyer. This measurement guides pricing strategy for portfolio expansion.
Substitution Effect
Consumers switch to a different brand when the primary option becomes too expensive. A high positive value for cross elasticity indicates that the two products compete for the same market share. If the price of a premium beverage rises, the demand for a value-tier alternative typically increases as buyers seek to maintain their budget.
Complementary Demand
Certain products are frequently purchased together to satisfy a single need. A negative value for cross elasticity shows that a price increase for one item reduces the sales of the other. For example, higher prices for printers often lead to a drop in the volume of ink cartridges sold because fewer consumers enter the hardware ecosystem.
Pricing Influence
Market leaders use these metrics to set floor prices for their secondary lines. Understanding cross elasticity helps prevent internal cannibalization where a discount on one product line accidentally erodes the margin of a more profitable one. Accurate modeling of these relationships protects the total revenue of the distributor.
