Questions and Answers

What characterizes elastic demand?

Price changes result in equivalent changes in demand.
A small change in price leads to a large change in quantity demanded. (correct)
Demand remains constant regardless of price.
Demand is unaffected by price changes.

How is price elasticity calculated?

Price Elasticity = % Change in Quantity Demanded / % Change in Price (correct)
Price Elasticity = % Change in Quantity / Absolute Change in Price
Price Elasticity = % Change in Price / % Change in Quantity Demanded
Price Elasticity = Absolute Change in Price / % Change in Demand

What does a price elasticity greater than 1 indicate?

Unit elastic demand
Inelastic demand
Elastic demand (correct)
