Study Notes

Supply and Demand Elasticity

Price Elasticity of Demand

Price elasticity of demand measures the responsiveness of quantity demanded to changes in market prices. When the price elasticity is high (-1 < E > 1), it means consumers change their behavior more as a result of price changes, indicating a relatively greater response from consumers to price changes. This can lead to either increase or decrease in total revenue depending on whether the price rises or falls. On the other hand, if the price elasticity is low (E close to zero or |E| < 1), consumer behavior changes less with respect to price changes, implying that small price changes do not significantly impact sales.

Price Elasticity of Supply

The price elasticity of supply assesses the responsiveness of producers to price changes when determining how much they produce and sell. If the price elasticity of supply is very high (E >> 1), this indicates a large shift in supply due to changes in price, which may cause shortages or surpluses. Conversely, if the price elasticity of supply is very low (E<<1), there is only a small proportionate change in quantity supplied with respect to price changes.

Cross-Price Elasticity

Cross-price elasticity examines the relationship between different goods and services by measuring how one product's price changes affect the demand for another good or service. In this case, if goods are substitutes, an increase in the price of one will lead to an increase in the demand for the other; conversely, if they are complementary goods, a decrease in the price of one will boost the demand for the other and vice versa.

Perfectly Inelastic and Perfectly Elastic

In economics, two special cases of price elasticities are mentioned - perfectly inelastic or perfectly elastic demand. These concepts are utilised to analyze extreme situations where all buyers buy or none buy a certain product regardless of its price. For example, if a person needs oxygen to survive, they would continue buying it even if the price increases infinitely, making the demand perfectly inelastic (-∞ < E < 0). Alternatively, if a luxury item has become so expensive that nobody can afford it, the demand becomes perfectly elastic (E = ∞). Similarly, perfect inelasticity applies when a firm cannot reduce production below or above a fixed level despite any changes in price.
