What is cross elasticity of demand and its significance?

Cross elasticity of demand measures the responsiveness of demand for a product to a change in the price of another product.

Cross elasticity of demand is a key concept in economics and business studies. It is calculated by dividing the percentage change in quantity demanded of one good by the percentage change in the price of another good. The resulting figure can be either positive or negative, indicating whether the goods are substitutes or complements. If the cross elasticity of demand is positive, the goods are substitutes, meaning that as the price of one increases, the demand for the other also increases. If it's negative, the goods are complements, meaning that an increase in the price of one reduces the demand for the other.

Understanding cross elasticity of demand is crucial for businesses as it helps them to predict how changes in the price of one product will affect the demand for another. For example, if a company knows that two products are substitutes, it may decide to increase the price of one product in order to drive up demand for the other. Similarly, if two products are complements, a business may choose to lower the price of one product to increase demand for both.

Furthermore, cross elasticity of demand can also be used to identify potential risks and opportunities in the market. For instance, if a business finds that its product has a high positive cross elasticity of demand with another company's product, it may indicate a high level of competition and the need for differentiation strategies. On the other hand, a high negative cross elasticity of demand could suggest opportunities for bundling or co-marketing strategies.

In conclusion, cross elasticity of demand is a valuable tool for businesses in strategic planning, pricing decisions, and market analysis. It provides insights into the interrelationships between products and can help businesses to make informed decisions to maximise their profitability.
