Micro 12 - An Elasticities Experiment Flashcards
What is price elasticity of demand?
Price elasticity of demand is how the demand of a product changes in relation to a price change
How can PED be measured?
%change in the QD / %change in price
What does elastic mean?
Change in demand is responsive to change in price
What does inelastic mean?
Change in demand is irresponsive to change in price
What is unit elastic?
Change in price is equal to change in demand
What does a PED of 1 mean?
The good is unit elastic
What does a PED of less than 1 mean?
Good is inelastic
What does a PED of more than 1 mean?
Good is elastic
What is Income elasticity of demand (YED)?
Income elasticity of demand measures the change in quantity demanded to a change in income
YED Calculation
%change in QD / %change in income
What is cross elasticity of demand (XED)?
Cross elasticity of demand measures the change in demand of one product due to a change in price of another product
How to calculate XED?
%change in QD of good A / %change in price of good B
What does a positive XED mean?
Products are substitutes
What does a negative XED mean?
Products are complements
What is a YED of 0-1?
Normal good
