What does cross-price elasticity of demand measure?

• A. The variance in quantity demanded based on the price of another good
• B. The interaction between supply chain efficiencies
• C. The fixed demand for luxury goods compared to essentials
• D. The effect of market competition on pricing

Answer: (A)

The cross-price elasticity of demand measures the responsiveness of the quantity demanded for one good when the price of another related good changes. This is particularly important for understanding the relationship between different products in the market. For example, if two goods are substitutes, an increase in the price of one good will typically lead to an increase in the quantity demanded for its substitute, indicating a positive cross-price elasticity. Conversely, if the goods are complements, a rise in the price of one would likely result in a decrease in the quantity demanded for the other, showing a negative cross-price elasticity. This concept is crucial for businesses and economists, as it helps in predicting consumer behavior and market trends when there are price changes. It informs pricing strategies and can also impact decisions on product development and marketing. In contrast, the other options do not accurately reflect the function of cross-price elasticity, thus reinforcing why the correct answer focuses on the relationship between quantity demanded and the prices of different goods.
