Chapter 6: Elasticity Flashcards
Price Elasticity
How changes in price effect the elasticity of demand
Price Elasticity Formula
% change in Q demanded / % change in price
Demand is ALWAYS what?
greater than zero
% change in quantity
2 / quantity
% change in quantity demanded
Change in Q / Average Q
Average Quantity
q1 + q2 / 2
Percentage Change in P
change in price / average price
If elasticity is greater than 1, demand will be what?
Elastic, having a large response to price changes
How does a price hike greater than 1 affect total revenue?
It reduces total revenue
If elasticity is less than 1, demand is what?
Inelastic, and is not affected by price changes
How does a price hike less than one affect total revenue?
Total Revenue is increased
If elasticity is equal to 1, demand is what?
Unitary elastic, changes to demand equally affect changes in price
How does a price hike equal to 1 affect total revenue?
Total Revenue is not affected
Cross - Price Elasticity
the way that changes in the price of one good can affect the quantity demanded of another good
Substitute good (Accounting)
When price of good x declines, demand for good y increases
