Economic Concepts: Price Elasticity of Demand Quiz

It quantifies how much the quantity demanded of a good changes in response to a change in its price.

When elasticity is greater than 1, demand is considered elastic, meaning quantity demanded is highly responsive to price changes.

The formula PED = % Change in Quantity Demanded / % Change in Price is used to calculate price elasticity of demand.

With an elastic demand (-2), a decrease in price leads to an increase in total revenue.

A price elasticity of demand value of zero indicates perfectly inelastic demand, where quantity demanded remains constant regardless of price changes.

In a perfectly inelastic scenario, quantity demanded remains constant despite changes in price.

Unlike factors such as substitutes and necessities, income level does not significantly impact price elasticity of demand.

A perfectly elastic demand curve has an elasticity value approaching infinity, indicating an infinitely responsive change in quantity demanded to price changes.

As time horizons lengthen, demand becomes more elastic, meaning consumers have more time to adjust their behavior in response to price changes.

Demand is considered perfectly elastic when the elasticity value approaches infinity, indicating an instantaneous and complete response to any price change.

With a negative but less than 1 elasticity value, demand is inelastic, indicating a less responsive change in quantity demanded compared to price changes.

A negative cross-price elasticity signifies that the two goods are complements, as a decrease in the price of one leads to an increase in the quantity demanded of the other.

An elasticity value greater than 1 but less than infinity indicates elastic demand, but not to the extent of being perfectly elastic.

With an elasticity of 0.5, an increase in price leads to an increase in total revenue, indicating inelastic demand.

An elasticity value less than 1 but greater than 0 indicates inelastic demand, though not to the extent of being perfectly inelastic.
